I keep seeing you guys posting vids of your single digit passes, so I thought I'd share my video of something a little bit different lol.

Timeslip at the end, but here are the vitals. .010 RT to his red light. I ran 15.18 on 15.39 dial (lol). He went 11.39 on a 10.90 dial (and I thought I was way off). Saw that he red lit, and just ran it out for a free time trial. Car was knocking with every tune, so I went in blind that pass with a different tune. Turns out my knock is fake.

My top end tune needs some work, as I was running 2.0x 60' all night. Easy 14 sec territory, but it doesn't matter. That was the last night in competition for my little ol 305, time to step it up a bit.

Getting a red light, breaking out or being way off your dial for whatever reasons is a bad way to give up a race but it's also the most common way to win/lose. If I cut a good light, ran close to my dial and still lost, I'd be shaking my opponents hand for a good race because he had to work for the win without me simply giving it to him.

I've gone many rounds winning against red lights and break outs. A win is a win but it's hollow. I'd rather cross the stripe at the same time and not know who won until I got the timeslip. I don't always see the win lights on the guardrail.

Getting a win against a faster car is what bracket racing is all about. All vehicles are equal and anybody can win. Money doesn't win you the race. You can go as fast or slow as you can afford and still have a chance of making it into the final round. Many times the slower vehicles are hard to beat.

The live commentary from the track announcer over the radio is a nice touch

hey is that one of those new sunpro tach's ? been thinking about buying one of those for my iroc since they are cheaper then the autometers, but i was worried it would have a dim shift light like most of the big cheap tachs

also it sorta sounded like ur engine nosed over for a split second after u shifted into third

Excellent post Alky. I agree, I thoroughly enjoy having close races over easy wins like this. Two weeks ago, I went down in the Mod Stock semi-finals by .0012, my closest race ever. I followed the guy back up to the staging lanes, told him what an excellent race it was, and of course got into racer talk.

It's funny that you mention the slower vehicle being harder to beat. Honestly, I'd much rather be chasing than being chased. I have a sense of power when I'm chasing, that when I catch the other person, I can pedal it or whatever need be to stay ever so slightly ahead of them.

Yeah, that's a SunPro Sport ST. PN# CP7900. Shift light isn't dim at all, I can assure you that lol. Yeah, the car does have sort of a dropoff right at the end of the track, that was the top end tune part I mentioned. It won't be close to perfect this year because I have $6E, and nobody has a hack for a WB, so I can't datalog my AFRs with the rest of my data. Once I wire up my 730, I'll have a much better tune.

ive had alot of tpi cars over the years, and i think just about all of them had that lil noseover/hicup on the track after the 2-3 shift

thanks for the pn on that tach and yeah i saw just how bright it was in the video, in my v6 car i have a cheap 5 inch with shiftlight tach but the shiftlight is useless as its so damn dim

PhoenixFirebird

iTrader: (2)

Okay, let me rephrase that lol. If anybody has a hack for a WB on $6E, I'm not aware of it, but it doesn't matter since I'm done for the year anyway.

What do you think it is? I always just assumed it's something where my timing isn't smooth or my fueling is off.

project89

iTrader: (1)

i never really paid attention to it. i do recall my 89 l98 car having it being very noticable bone stock, i dont rember if it got better or worse after i ported the intake though

all of my cars ran the stock tunes as back in the day i wasnt into tuning them,mostly just simple boltons like headers and intake port work etc

We still Need to get rid of that glitch. Good job though. Love seeing a thirdgen get a stang.

Any more thought into what mask your going to use for the new engine?

Btw the car did bog when shifting, drive it once and watch the afr and see what it does when the shift takes place.

PhoenixFirebird

iTrader: (2)

Yeah Mark, not too worried about the glitch though, probably won't run it very seriously anymore. Going to the 730 ecm, so I may use $59 like you have, that way you can teach me from your experience

Same thing with the bog though, I'll wait until I start tuning the 730 for the new build before I worry about it.

I'll be back

From your vid it looks like your converter is locking up in third, I noticed your rpm's dive down when it seems to nose over.

fasteddi

iTrader: (2)

Whatever mask you choose Ill help you bud. Speed density is a breeze in my mind compared to MAF. But the 7730 ecm is a way better ecm then your current 165 which you already know. Many more options and control over tuning!! Theres a few other codes that are pretty damn good and are about the same control wise. $58 is also a good one. $59 is just a modded $58 mask. Being that your staying n/a a $58 is comparible. I want to add that the $59 mask like I have has a horrble resolution...lol if you would ever go into a boosted application. Read up on the masks and decide which one you want to run. Either way I can help you alot in tuning once you go speed density. Its not that I cant learn MAF, I just feel much more compfortable with MAP systems...lol THe VE and SA tables and such are to much easier to me...

I've got a 6e WB hack, pm me and ill send it to you. Its very nice seeing the WB afr in the datalog.

Ive got all the stuff he may (if he chooses) ever needs to datalogg the WB and a few other things for both code59 and $58. And also some damm good starter bin files for a V8 N/A car(0-100kpa) I dont know how anyone can tune without RT datalogging the sensor. I guess i've just been spoiled from day one. Also have the injector duty cycle in there so that you dont have to look at the palse width, and have to calculate how much injector your using at whatever Rpm/Kpa

PhoenixFirebird

iTrader: (2)

Absolutely! I may only take it to the track once more this year, but at least I'll have a datalog for it.

I've pretty much just watched the guage at WOT, and if it's in a decent range of 12.5-13.0, I'm content with that lol. I know it's not the best way, but hey, it worked out fairly well

The $6e WB bin is available in the DIY PROM section. Keep bumping this thread to remind me to find the link for ya when I get to my computer!

Cool whatever works man but as soon as you get the modded 6E mask, youll be in love

Then you can do some part throttle tuning which is much more time consuming and precise. But that sort of tuning will make you a better tuner overall and a faster one at that. I remember taking 1-2 hr drives just to collect data for part throttle tuning. From driving in town to the country to the e-way. Then export the data into excell and turn that into 10-20K+ cells of info then sift though that and work it out. I will add though that im ADDICTED to tuning!!!

That is exactly what is happening. The ECM is hard coded to engage the TC Lockup over 75mph I think. Might be off on the exact MPH, but its there in the code if you look.

My car does it here as well:

Is this what you're referring to? I noticed you said "hard coded," but I went through all my TC scalars anyway, and sure enough, that one is set at 80 MPH. Is that the scalar that's making this happen?

Thanks 88gunmetalgta, between you and TPI-Formula350-, I'm going to mess around with this hack a bit, even if I only make one more showing at the track this year. Thanks guys!

Thirdgen89GTA

I used "hard coded" in the wrong way. Because it is programmable and can be changed so its not technically "hard coded". But every factory ECM tune i've ever seen for a thirdgen with an auto has the lockup at 80mph or so no matter what the throttle position.

I think it was to reduce the heat generated by an unlocked converter during extended WOT periods. An unlocked converter makes some big heat after a while.

fasteddi

iTrader: (2)

Is there any tables or scalers that have TPS Vs. Mph for your lockup?? Or delta vs Mph?? Im not aware of what the 165 is able to do. I have mine to lock up at 40 mph but thats when the tps is under a set TPS that I tell it to.

My thirdgen was pre-set to lockup at 45Mph from the factory. Keep in mind that a lock up converter was first designed for MPG only.

If there is a upper and lower lockup area make sure to have them at least 5-10mph apart so that the converter doesnt lock up and unlock constantly. That can ruin your silenoid and or trans. Also look and see if there is a temp area, not that you should change that but its nice to know what it is if your running lower temps then usual. But if you want to enable it period then just jack the temp up to 155c or if your in F whatever the highest is.

I'll be back

Not sure if you'll see a gain or not but you can try disconnecting the plug on the trans to keep the converter from locking at the track.

After doing a bit of research, I just burnt a new chip that moved the unlock prevention threshold up to 100 mph. I haven't tried it out yet, but I'm pretty sure that's it, since its the only TC value at 80 mph, and based off of Orr's post.

fasteddi

iTrader: (2)

Did you wire in that WB to the ecm yet to try out the datalogging and modded adx? If you want you can send me your modded adx with the WB on it and I will add the injector duty cycle to it so you have a history table and data for that insted of that dumb injector pulse width...lol

I finally got not lazy and opened your files I had. Heres what I see.



Tables for the TC lock up:

76mph=89% tps to lock up
84mph=99% tps to lock up


These table are what you need to change unless you want to take one chip and mess with the unlock prevention and one that has the stock limit so you do lock up your converter.

I would personally just change the % to be maxed at 80-85% in those 52mph-100mph cells just because your TPS% may be off and you do still want that TC to lock when your just crusing. This is what I did in my car and never had a issue with the TCC lock up or having to totally disable the lock up. Last thing I wanted was to be crusing home on Rt20 at 3K rpms with open exhaust....lmao I needed my TCC for that and added Mpgs. Everyones different though and has there opinions on that.


Tables that you can change
TC unlock speed vs. TPS% (not in 4th gear)
TC lock up speed vs. TPS% (not in 4th gear)



Now for the scalars:

Yea your Unlock TCC prevention scallar is a quick fix "I think" as im not sure of the hystericals that have to do with it and if any other things are tied into it. But personally Id just change the Tables as it will do the same thing. I always look to change a table before a scaller in many cases.



My one question would be is how fast is it when you shift into 3rd gear. For me its about 78mph but thats at about 5900rpms. I think that your tables just needed modded because if the 165 is anything like my 7730 the rounding process would put your third gear shift(or shortly after that) in that 84Mph cell on the lock up TCC table. Look what it says there for TPS 99+%. Now I would think that if you just changed the cells at 84mph and up you would fix your problem and see that you dont have to eliminate the lock up.


Also andrew can you link me a datalogg or just tell me what your MPH and TPS %(vts) was when you see the TCC status as being first locked up on your exported log???

Shift into third at about 78 mph, right around 5000. I'll have to look at more of my datalogs, I'm on the other computer at the moment lol. Probably won't have WB hooked up for Sunday, if I even go. So far the weather isn't looking pleasant...It's been raining about every day here, silly Ohio.
