Re: Another Turbo 2.8 in progress
Couple more questions, If I piggyback MS do I need the relay board? And should I go for the 8 foot or 12 foot cable? I know the kit comes with the connectors but I hate messing around with them.

Re: Another Turbo 2.8 in progress
Why would you piggy back the MS?
It's a full EFI controller, so why not use it that way?
For the extra $20 or so, I strongly suggest the V3.0 PCB, as a fellow electronic engineer (in school currently), I know that you will likely want to have easy ability to modify and add to the main board, which the V3.0 PCB is the best for this.
If you go with the 12 foot harness you can always cut it back.
Alternatively you can use the existing harness that will have all or most of the relays needed, you will have to invert the fuel pump control output of the MS to work with the GM fuel pump replay wiring. MS uses a ground trigger to the relay, GM uses a positive trigger to the relay (they did this for safety reasons in a collision in case the wire git cut and shorted to ground, it would force the fuel pump off). You would just need to make a short adapter harness or change the connectors at the ECM location.

Re: Another Turbo 2.8 in progress
Baby steps Six, lol. Im going to start with it piggybacked to get used to tuning, etc. Im learning with this project not only tuning, but turbo setups too. Im planning on starting with the stock computer and the turbo setup with the injectors to start. Then since I am getting the MS kit, I will assemble it and make sure I have everything I need before going further, and all the information I need.
So get the turbo setup on first and get it running without tuning at low boost, Once I am comfortable with that, I will take the next step and go with MS piggybacked. After I am happy with that I will go with stand alone.
I am basically going one step at a time to make it easier to backtrack if something goes wrong. If I try to do everything at once, it makes it that much harder to troubleshoot.
I am going to weigh my options before getting the MS, but I am going MS. I will decide once the turbo is in and running, and after doing research on both 2.2 and 3. Is the 3 all through-hole or is some of it SMD? I can work with SMD but would have to get a proper setup when dealing with an ECU.

Re: Another Turbo 2.8 in progress
Money is in, time to start spending )))
I pick cheap and reliable. Time isn't an issue at this point but I will be going pretty quick. Hey project, think you could shoot that base tune for MS my way?
Ok so going to go the MS 2.2 route. If I piggyback and use the MAP sensor with the MS can I get rid of the MAF? Easiest to take the MAF out of the picture which would mean less cost.
also,
VW VR6 92 99 Golf Jetta Passat 36lb 355cc Fuel Injectors 0280155811 | eBay
Will they work? I want to get the fuel taken care of off the rip, and I honestly don't think I will have a need to go higher than that for the first build.
Other things I am looking at,
What all needs to be done for a FULL EGR, cruise, and evap canister delete??? De-cluttering the engine right before the build.

Re: Another Turbo 2.8 in progress
Yep, the MS doesn't need a MAF to work. Since you're going to run it with the '302 at first, I would start with the injectors I'm sending you so you don't max out the BLM and trip a rich code.
Edit- NM, you're piggybacking the fuel so it doesn't matter.

First thing to do is learn about tuning, forget adding any power adders, learn what an engine wants, how to give it that and what changes have what result. Once you're familiar with that, THEN add the power adder/built engine/whatever.
When you add larger injectors to a non tuned set-up all you will end up doing is washing down the cylinders and giving yourself more work than you need to do. At start up, the GM computer is in open loop and will not trim back the fuel, so you will be injecting more fuel than needed and give yourself more headache than you need.
If you're not going to learn about tuning first, then add the tuning ability at the same time as the power adder.
I also see going piggy back being a more difficult learning experience. Fuel delivery and spark timing are NOT mutually exclusive. They directly effect one another. Change the timing, this will effect how the fuel is burned in the cylinder ans a change in spark timing will be needed, same applies for fuel, change fuel delivery, this will likely cause a different need for spark timing, among many other changes.
The V2.2 and V3.0 MS boards are through hole. The V3.57 is SMD, and not sold as a kit.

Re: Another Turbo 2.8 in progress
u do not need the relay board .
if u piggy back the ms u must leave the maf sensor hooked up for the 302 ecm to control spark properly
i would just do full ms install since im supplying u a full base tune this will get u close and u will have to fine tune
the only thing i dont like about supplying a base tune is that the user using the base tune really doesnt learn anything ,the best way to to learn is starting from scratch
but its upto u i can give u a base tune u can drive around on or i can give u a tune that will get the car to start and idle , and u will have to do some tunning to get the car to drive around prooperly
for the extra few bucks get the 12 ft harness , its nicer looking when u have to cut back wires instead of extending them

Way wrong way to go about this IMO. Basically you're doing it backwards if you want to do things in certain steps.

I know its not really all that good to get on the car while its cold, but is this why it feels more powerful before warmed up? I have 19lb injectors in right now.

Can I just grab a wideband O2 sensor and use it with MS to monitor realtime on the laptop? I assume so.

Re: Another Turbo 2.8 in progress
Tuner Pro doesn't work with MS.
AFAIK only Tuner Studio is supported anymore for MS and the latest firmware.
The cold start enrichment is only part of the reason a car appears to have more power when cold. But what I was getting at was that in cold start, the larger injectors will be delivering more fuel than the engine needs, washing cylinders, adding fuel to the oil and possibly making it difficult to keep running, just how far out the difference in injector size is.

Re: Another Turbo 2.8 in progress
i use both megatune and tuner studio, along with megatunix
ms1 and ms1 extra code will run on megatune or tunner studio, megatunix
ms2 and ms2 extra upto a certian release will work on megatune megatunix , after those releases u have to use tuner studio or megatunix
i prefer megatune when i can use it as when i started with ms years ago its what everyone used and i like the layout of the software the best
as far a sa wideband u still need a controller for it my recomnedation is the invotive mtx 199$ last time i looked , aem eugo 165$ ( which i currently use), or the one six shooter always recommends the diy slc wideband dont know price off hand but i think its in the 150$ range
stay away from the inovate lc1
my friend recently purchased an glowshift wideband for around the same price as my aem it seems to work very well
21/24# injectors is about the max the car will run on with a stock ecm , when in closed loops it will pull back enough pulse width to run ok , but it will still be about 1 point to rich
with 21 or 24 pound injectors on a 2.8 u actually have to unhook the cold start injector or u will foul the plugs on a cold start
witht he megasquirt hooked up u will also have to delete the cold start injector as the ms ecm sends cold start enrichment fuel threw the port injectpors unlike the stock ecm that relies on the csi

Re: Another Turbo 2.8 in progress
there site and store are both down , so i dont know
i have used there widebands before, i installed one in pilsburys turbo car , the old tiny one smaller then a tic tac case , i liked it , only thing i didnt like was the terminal strips on it kind of sucked

Ok, so here is what is ordered so far.
Turbo setup
MS v3.0 kit all cables too
AEM Uego wideband kit
Digital Boost gauge -14 to 21psi
6 36lb Bosch injectors from southbay
I know I will need some little stuff here and there too

Re: Another Turbo 2.8 in progress
off to a good start , did u get an ms1 or ms2 kit ?
once u nail down the entire combo a lil better i can shoot u over some base tunes

Re: Another Turbo 2.8 in progress
Im getting 22lb disc injectors with the turbo, thats whats going in first,
for tuning probably putting the 36lbs in

Re: Another Turbo 2.8 in progress
What waste-gate did you get with the kit? Do you know what the spring pressure is? 22lbs injects will only take about 4-6psi if you dial it in before they max, go static and you go lean. So be careful the first time out if your unsure of the spring pressure. Watch that KR, PSI, and AFR. You can always get a adjustable boost controller or even a gm solenoid one like the one I run, i would think that MS would allow that output.

the ms does boost control,i would not even put the 22# injectors in , just put the 38's in it and be done with it

Re: Another Turbo 2.8 in progress
Yea i recommended at least 36's because I know i maxed the 28lbs out fast. might as do it right the first time. Boost is pretty addictive.

Re: Another Turbo 2.8 in progress
lol i went right to 80's in the iroc turns out they arent big enough dohh, next step is a set of 120's for me
hey fast need a set of 80's for the new engine? lol
36's will prolly be fine for a 2.8 but on a 3.1 or 3.4 i generally recomend to start with atleast a 42# injectors

Re: Another Turbo 2.8 in progress
Na no 80's for me. I think the 48lbs will do. Besides i dont think my 7730 injector drivers can handle low z injectors. Your maxing out 80 lbs injectors?? Wow thats with pump gas not alky?

Re: Another Turbo 2.8 in progress
What waste-gate did you get with the kit? Do you know what the spring pressure is? 22lbs injects will only take about 4-6psi if you dial it in before they max, go static and you go lean. So be careful the first time out if your unsure of the spring pressure. Watch that KR, PSI, and AFR. You can always get a adjustable boost controller or even a gm solenoid one like the one I run, i would think that MS would allow that output.
EGR delete, Cruise delete, and charcoal canister delete will be done too.
Once the setup is all buttoned up, I will then build the MS and make the endeavor into tuning and hooking all of that up.
lol i went right to 80's in the iroc turns out they arent big enough dohh, next step is a set of 120's for me
hey fast need a set of 80's for the new engine? lol
36's will prolly be fine for a 2.8 but on a 3.1 or 3.4 i generally recomend to start with atleast a 42# injectors

Re: Another Turbo 2.8 in progress
Heres what I did back when I ran a IC. Worked quite well. Else then I was running a very inefficient t3/4 for the set up I had.

http://scontent-a-iad.xx.fbcdn.net/h...73899570_n.jpg
The intake temps were great till I got up arround 10psi and then the turbo was just unefficient for the power I wanted. Also when I coupled that IC with the alky injection I have now, I always got little or no rise in temp on intake temps(sometimes it was below ambient temps) when racing the 1/4 mile which is a great thing that kept my stock engine in one piece after all the times down the track when I first learned how to tune. Im pretty sure alky has saved me more then once....lol

Re: Another Turbo 2.8 in progress
i was hitting 93% duty cycle on the when i sprayed the nitrous @ 50 psi base fp
and yes on pump gas , once the new motor is together prolly this wekeend i plan on being able to max the 80's on boost alone without the nitrous
shooting for 4 digits on boost only and 1100-1150 with the spray (crank hp )
im pretty sure the pair of gt35's @ 25 psi will get me there
thats right u cant use low z stuff

Re: Another Turbo 2.8 in progress

Re: Another Turbo 2.8 in progress
The one I have is set for 6psi. I was thinking though, since you're going to put together a hybrid eventually, are you sure you don't want a t3/t4 instead?

Re: Another Turbo 2.8 in progress
I should be able to do a bleed switch on the T3 for more boost or no?
Project - Its the open grille with a custom expanded metal grille I made

Re: Another Turbo 2.8 in progress
Well that was quick. Got the MS1 v3 kit and cables in the mail today. AEM wideband is set to be delivered tomorrow. I love early presents
The tube from the Pass side valve cover just gets a breather filter on it correct?
And how about the tank vent line. I was thinking check valve on the line to prevent pressure blowing out, but will let it pull in when the fuel level goes down. That with a vented cap should be good no?

Re: Another Turbo 2.8 in progress
psst u deffinatly want the t3/t4 turbo , the t3 is only good to about 250 hp total and u will make more then that even before the hybrid build
i just left my vent line disconected and bend it upwards a lil, fuel wont come out of it
the pasengerside valve cover tube gets a breather

The hybrid build is a long way off right now.
I've been working on cars since around 7 years old, this is my first turbo, and first crack at tuning. But I do tend to learn a bit faster then others would so it should go pretty well. Plus I have the help of Thirdgen.org, my mechanic father, and a couple friends that have done turbo setups before.
That WBO2 has 4 wires, one for pos(red), one for gnd(black), one for 0-5v out(white) and one for serial out(blue). I want to hook it up before the turbo goes on so 2 questions.
1 Do I hook the 0-5v out to the stock o2 ECM wire for normal operation?
2 Is the stock O2 bung the same thread? The AEM comes with an M18x1.5 bung

Re: Another Turbo 2.8 in progress
The stock is the same thread I think. But just try to thread it in, if it doesnt go in with your hand then its not right. But i am 99.9% sure all o2 sensor threads are the same.
The 0-5vts is your linear output. This is what you would either want to wire into the MS or if you had a good hack on a obd1, you could wire it into the stock ecm, like many do on obd1. So that you can datalog on Tunerpro and record the afr. Makes tuning alot faster exspecialy on part throttle and idle.

Re: Another Turbo 2.8 in progress
i have to read the manual again but i think the blue wire will do 0-1v output for the stock ecm , if not for now weld in the bung it came with and just use it as a standalone wideband gauge

Re: Another Turbo 2.8 in progress
checked the manual the white wire can feed into the stock ecm , u have to set the rotary dial on the back of the gauge to p4 which is simulated narrow band output 0-1v on the white wire
info can be found on pages 10 and 11 of the manual

lol i had to go and find the manual , i havent looked at since i installed it a while ago , once u hook it to the megasquirt u can reset it to 0-5v output for more accurate readings to the ecm

Re: Another Turbo 2.8 in progress
If i'm deleting the egr, cruise and charcoal canister do I still need to keep the "orb of power" vacuum canister?
Also what vacuum lines need to stay connected or re-routed to?

The vac ball is there for accessories, but you don't need it. Here's the other turbo I was talking about. It has an internal wastegate and BOV.

I don't have specs, but I had both on my car and this turbo had much better response and wasn't top end limited like the standard t3 was.
