Re: Chronicles of a 9 Second Trans Am... Final Chapter
Looking at the schematic, if SpareADC2 is unplugged and you apply +5 to spareadc, it's going over the 1m resistor to the ground on C40 and showing on spareadc2 on the CPU side.
I don't get why they designed Spareadc2 this way.

Since MS can work with "any" sensor, they were worried about biasing sensors with low resistance. If they put in bias resistors it would effect the sensor itself and the reading it produced. So they opted for no bias resistors. See my fix for interweaving A/D reads of a known value.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
I will explain it another way.
1) SW sets the A/D mux to read spareADC that is connected to something sitting at 2.0 volts.
2) Next SW sets the mux to read spareADC2 this is floating (connected to nothing). The sample and hold cap was just charged to 2.0 volts from previous read. SW will read approx the same value now. Therefore, it appears that you have "leaking" when in fact you have a floating spareADC2 input that should have been biased to a known voltage.
Note that the 1 megaohm on spareADC is not that good of a choice either since the RC time constant with the sample and hold capacitor is a loooooooooonnnnnnnngggggg time.

So are you saying the hardware ADC itself is re-using the stored value? I'm confused.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
It's literally reading the processors ADC.
Suppose your job is to listen to two people saying words and report the last word you heard to your boss. Person A says "car" so you tell your boss "car". Person B says "dog" so you tell your boss "dog". Person A says "foo" so you tell your boss "foo". Person B says nothing so you tell your boss "foo". Your boss thinks Person B said "foo", but they really didn't. This is the broken wire/case you are seeing with your MAP/IAT.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Yes it is, but understand that there is only one ADC with a set of 8 switches in front of it. So, if the switch is set to MAP input then the ADC has the MAP voltage and SW reads this voltage. Then if the switch is set to IAT input which is floating, then the voltage stays the same at the ADC and SW reads this voltage. That is, it still sits at MAP voltage (or pretty close to it) when reading the floating input.
Suppose your job is to listen to two people saying words and report the last word you heard to your boss. Person A says "car" so you tell your boss "car". Person B says "dog" so you tell your boss "dog". Person A says "foo" so you tell your boss "foo". Person B says nothing so you tell your boss "foo".

I assumed each ADC in the CPU was a completely redundant component.
So the "Fix" is to bias the circuit to ground, but B&G didn't do that to have more flexibility on the read side. (At the expense of potentially not realizing a sensor is our of whack).
Is this why I see a lot of posts about guys running resistors to ground on their input's on the ms forums? I've always just glanced over those threads.

Your trap speed will tell you the true story even if you run a 14.0. At 3500 pounds, 410 Horsepower should net you 115-mph in the 1/4 mile, which translates to a mid eleven second ET with a very good sixty foot. Definitely looking forward in seeing the results...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Yeah, these threads tend to derail when everyone's ego's want to bonk heads with one another. Human nature. I don't mind at all so long as the information is beneficial for the readers. As far as updates go, I should have the drivers side installed today and hopefully upload a quick exhaust video tonight, or definitely sometime this weekend. I can't seem to find both exhaust hangers for the muffler, and although Walker makes both, most auto stores don't carry them, they are special order. I still have my 17" 315 MT drag radials, but I hesitate putting them on a 9.5" torque thrust rim...

I do get nasty PM's from time to time from two of our younger members complaining. I suspect it's because their build threads get zero activity.

Ever driven a C4? Nice cars but very road sticky and feedback sensitive on the steering. My C3's are more like Jeeps.
I have regular 245's right now on the Formula.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
The headers are great for the money.
The o2 sensor location is whacked though. I had to "modify" my floor a little with a BFH.
-- Joe
#174
Re: Chronicles of a 9 Second Trans Am... Final Chapter
What do you mean modify the floor for the O2 sensor? Are you running your wideband in that location? I put my narrowband in that location, fits good, but will be welding an O2 bung into the y-pipe collector for my wideband. So far everything fits perfectly, and believe it or not, despite cutting the corner of the tranny's bell-housing off where the dust cover bolts to, I realized I didn't even have to do that. They actually went in very easily. Anyways, these pics were taken after bolted down. Spark plugs are in, wires will be shortened and run overhead. When I pulled the starter I seen that one of the three fusible links' terminals were broken off, so I need to correct that before reinstalling the starter. Wanna get this on the road as soon as I can, so hopefully today I will have an exhaust clip for the thread...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
I have AFR heads which raise the exhaust ports a little bit, so my headers are a little closer to the floor than yours probably.
Speaking of which, what heads are those? A 1990 should be centerbolt of course.

The stock/original Speed Density LB9 is wrapped and sitting in my garage. This '90 GTA came with a manual too which was pulled. I picked up this stock LB9 w/700R4 from an '86 Iroc a long time ago, well, two to three years ago, low miles, as this is the 305 I am using as a test mule to be tested for nine seconds. I explained this awhile back, but I keep forgetting this thread is still essentially new, and is missing key information. This is why I don't really care what happens to this engine. Bone stock 305 w/auto, I ported the 416 heads along with the earlier TPI intake system. This is also why I had to make a new MAP sensor bracket a few pages ago because this plenum is for a MAF system, I have the original Speed Density setup on the original engine...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Exhaust isn't all the way hooked up, just the headers into the y-pipe for now. I still need to mate it to the Flowmaster, it's just way too hot out to weld. When I pulled the turbo the tune was dead on, but now on the first try it needed lots of tuning down low, what a freaking difference though. Had the engine cut out on me when the fans kicked on, didn't even think to look at the BLM, so first I adjusted the fan enable, had the second one come on five degrees after the first. No difference, stalled out when first fan kicked on too. Watched the BLM when I tried again, and damn, 156 BLM. Added some fuel to the VE and got it down to 132 BLM for now, idle is stable. Damn thing already sounds unreal, had neighborhood kids flying over to check it out, that was cute. Anyways, will try to bang out the rest of the exhaust tomorrow, time to eat...
Off topic, but hey guys, mostly guys 35 and up, what do you think of when you hear the words Ford Focus? Yup, me too, absolute garbage lol. But look at this damn thing, where the heck was this when we were kids, ehh? This thing is freaking stock...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
I've been really thinking about buying a new vette. Just don't know if I'd drive it enough to be work paying 60+.
Been looking at Mastercraft boats lately too, the V drive stuff. Seems like that's what everyone is buying now. But setup the way I want starts around $130.. Again, kinda step for something I use a dozen times a year at most.

Anyways, I only have a few hours to give to the car today, if I don't get the muffler bolted to the headers setup, I'll still try to grab a quick video to upload. By the way Joe did you take the Formula out for a test drive yet...?

Re: Chronicles of a 9 Second Trans Am... Final Chapter
No more vette's for me, the last one was leased too, insurance was an absolute waste. A few weeks back Joe the tree in my yard was struck by lightning, and luckily it landed nowhere devastating to the house. I'm dying for a pool, and the money I threw away on that vette could have had me swimming the day after that tree came down lol. Also tired of lying down while driving...
Have not touched the formula this weekend, working on my main house. Today I'm a plumber haha.
Good luck with the exhaust! Post a sound clip

Dont buy a automatic Focus. From what I hear, the torque converters go all the time and their on intergalactic backorder. Brand new cars(Still under warranty) sitting at dealers waiting for them to come in because they wont move at all.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
I guess they went to a new sort of style transmission. I forget what my friend said it was (Hes a service writer at the local dealership) but its along the lines of VW's DSG. Focus's and fiesta's use the same thing, so id stay far, far away from those cars if their a automatic.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Joe, for a second I mistook the Ford Focus with the Ford Escort, that is why I compared it to the early Chevy Chevette a few posts up...
Dan, I think I'm going to stay away from it. I looked at one by the dealership this morning and it didn't really grab my attention like the one in the video, and the last thing I want to do is to buy one and then start modding it.
Can't get over the amount of tuning that was required to get it back to the way I wanted it from a simple exhaust swap. That turbo was very restrictive. Gotta go back under again in a few minutes as I have to double check the torque readings on the flywheel to converter bolts. Yup, I hear a slight chirping again that's getting louder, and the starter housing looks chafed, sigh. Anyone wanna hear it???? Yay!!!!
Who hear plays Mobile Strike by the way? Get to the chopper!!!!!!!

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Purchased two Walker exhaust hangers that were made in India, nuff said;
The welded arm bracket on the exhaust tube on the right is exactly 4" high, which matches the stock location for the original one perfectly just before I welded it. I was going to pull down the muffler, cut the bracket and add about an inch and a half to it in length to correct the appearance when my buddy gave me a better idea, just pull the exhaust hanger and add a one and a half inch spacer between the hanger base and the frame where it gets bolted. I have to correct this issue before welding the intermediate tube to the over the axle tube. Don't let the appearance fool you, the dual exhaust tubes are about eight to ten inches tucked in from the bumper...

I welded a one inch extension onto the Walker piece, all leveled up...
Joe, you'll get a kick out of this, wanted to share an amusing evening. Settled on a new 2016 Hyundai over the Ford, but I picked up another car along with it on the way back. Passed a used car dealer with an older Buick Regal that looked to be shunned by the much newer cars that were surrounding it. I pulled over and asked about it just for the hell of it because I wanted a beater for the colder weather, and I love the way the third gen coupes look. After seeing the mileage, then the price, I pulled out the wallet lol...
I get it to the house and figured I would give it a once over in the garage. Fluids all look great, idles like a kitten (save for a small vacuum leak), but I wanted to give it new brakes and rotors because that was the main issue; brakes, rotors, one hung caliper and a wheel alignment. I cried about it at the dealer acting like it was a big deal, and he lowered the price lol. He was already asking practically nothing for it, he must have wanted to just get rid of it. Anyways, got the fronts done in a few minutes, but the backs... jeez, damn. What the hell was GM thinking. It took me almost an hour to figure out I was dealing with "pivoting" single bolt calipers. What the hell was the design team smoking back then lol. Guess they figured luxury car, not performance oriented, but still, they should have used two freaking bolts per caliper back there.
But anyways that was my evening, added a "third gen" Buick Regal to the stable. I don't think it's possible to slap on an 3800 L67 supercharger onto the 3800 L27, would be pretty cool though if it were possible, would keep boost low, and would definitely go Megasquirt then for sure. She's a two door coupe and runs like a freaking champ. Great knock around car, especially for what I paid for it, which I'm still in shock about...

What the hell was the design team smoking back then lol. Guess they figured luxury car, not performance oriented, but still, they should have used two freaking bolts per caliper back there.
But anyways that was my evening, added a "third gen" Buick Regal to the stable. I don't think it's possible to slap on an 3800 L67 supercharger onto the 3800 L27, would be pretty cool though if it were possible, would keep boost low, and would definitely go Megasquirt then for sure. She's a two door coupe and runs like a freaking champ. Great knock around car, especially for what I paid for it, which I'm still in shock about...
Joe, you'll get a kick out of this, wanted to share an amusing evening. Settled on a new 2016 Hyundai over the Ford, but I picked up another car along with it on the way back. Passed a used car dealer with an older Buick Regal that looked to be shunned by the much newer cars that were surrounding it. I pulled over and asked about it just for the hell of it because I wanted a beater for the colder weather, and I love the way the third gen coupes look. After seeing the mileage, then the price, I pulled out the wallet lol...
I get it to the house and figured I would give it a once over in the garage. Fluids all look great, idles like a kitten (save for a small vacuum leak), but I wanted to give it new brakes and rotors because that was the main issue; brakes, rotors, one hung caliper and a wheel alignment.

I had the previous body style in the early 90s. Was an '85 regal. Originally I think it had a 307, did a 350/th350 swap in it. cool car but it rotted out.
I wouldn't mind finding another one, but they are all crushed or high dollar restorations.
Have you driven the bird yet with the new exhaust?

This Buick has beaten it's fair share of grocery getters in the last 24 hours, including many BMW's rolling up to get some, I really wanna keep her and do something with her, like install a '95 M62 supercharger from a Buick Riviera, but I am going to flip it once I take care of a few more details. Should net me half the cost of the polished F1A setup for the GTA. I really hate to sell her, but I am not a big fan with red on red. Sooo close to painting it Black and keeping the chrome exterior, installing GN interior w/chrome rims and create a 90's Grand National, but I need to focus on the GTA lol...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Oh yeah, they were stepping on it. Don't get me wrong, I wasn't pulling them with the Buick lol, but I was ahead. The car is starting to grow on me, again not too crazy about the Red w/Red scheme, but I am digging the style. Supposed to be working on the GTA today, but I'd like to get some fresh plugs, wires, coils and air filter for the Buick. You gotta see the exhaust lol, my gawd is it restrictive. Speaking of superchargers, there is someone local parting out a '95 supercharged Riviera. Hmm...
You have a lift in the garage ?

Didn't like the way the front tires were feeling so I bought two bearing assemblies. Tie rods seem fine. When under the Buick I seen that someone pulled the AC compressor in favor for a delete pulley, but left the AC compressor connectors in place. Might wait on that though. Already replaced the thermostat, got an oil change w/filter, air filter, but now I'm thinking tranny mount because I feel an ever so "slight" shake when hitting the throttle. Yup, a day that was to be dedicated to the GTA and I am back on the Buick lol. Gonna do the HUB bearings now in this 90 degree heat...
The 305 in the GTA needs to be pulled, I am not dropping the trans to change the flywheel this time, and it's definitely the flywheel. With an open exhaust it was hard to tell, but with the full exhaust now on you can hear the flywheel rubbing against either the converter, or the back of the block. Sigh, there is always something. I have a spare SFI flexplate to use, just effin tired of pulling the damn engine...

Re: Chronicles of a 9 Second Trans Am... Final Chapter
It doesn't get as hot under the blistering sun when under the car lying on the concrete, but yeah I have been looking to have the driveway redone very soon. I don't have a full lift in the garage, but a buddy of mine hooked me up with something that I use out in the yard. I get about four feet of clearance when under the car using it. This is why I am very lazy when it comes to trans removal, I don't have it in me like I used to, especially with only that much working space to utilize...

I can't crawl around on the floor working on cars, I've got dramatic back and nerve damage. I'm lucky I'm still vertical.
Go park the Buick out back and work on the GTA. Summer is almost over. Get that F1 ordered.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
That's honestly why I want to get the Buick done asap, I just want to flip it so I can order the Procharger. I have to freaking order the full Intercooled version from Procharger despite not even needing it because I am using the 4" Intercooler I have on there already, just need to figure out the intake routing by the battery. I don't know if I can squeeze 3" tubing through the fender where the horn is located down to the Intercooler and there is no way I am running 2 1/2", so the battery might have to go in the back in the hatch again so I can reuse the routing that I had for the turbo. I know I am losing the wiper fluid reservoir, so now I have to use the coolant reservoir for the alky and get my hands on a small coolant reservoir to mount next to the radiator...

On the flip side, if you wanna sell the intercooler and piping I might know a guy. (me) who might be interested.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
Is the TPI bracket still being produced by Vortech because I read they discontinued the system? That is the only reason why I am going Procharger, because Vortech apparently stopped making them. Definitely Joe, if you want the Intercooler w/tubing just say the word, because I really like the one I already have mounted, I have it setup so that it looks factory, even the Power Steering lines are hooked to it, and the bracket arms fit snug under the radiator support. People that see it can't believe a 4" is tucked in there the way it is...
I'd be interested in the bottom mount procharger intercooler and piping if the price is right, just remember I'm a cheap ***.

Re: Chronicles of a 9 Second Trans Am... Final Chapter
I did a whole write up on it under the power adders section. You wont have to go as low as i did and modifiy the alternator case seeing your charge pipe isnt going over the alt.
