ECMlink ECMLink newbie

[Ghost_92TSi]

Just going to post this here because the other section is picky. I just did a stock rebuild on my car:

I need to update my mods list but I added bushing this time around on the front subframe, SB SS-TZ clutch/pp. Using the GM 3" maf to ECU, FIC 750, and ECM link.

Been reading on ECMlink wiki as well as other post of here. I still need to re read through the WB to ECU hook up. I just wanted to start the car and see if I could at least move it around.

Just trialing and error right now, I did some adjustments to the MAF and I noticed that was better.

I did fix all my boost leaks prior to this, replaced injector seal, TB gasket, Tighten one coupler, and J-pipe gasket.


My o2 only cycles once or twice every now and then?

I also noticed it leaned out when I reved at the end.

If anyone notices anything I am missing: or better things to look at. lmk.

Guess they moved it here anyways. Base timing was anout 4 degrees a adjusted it closer after. Boost leak is good. Still going through the other list of requirements.

I was using an innovative wb and it was running really rich 10-11 at ldle. Changing the hertz down alot got me to 12-13. I changed to the stock mas and same thing so I can rule out the gm maf.

The above really helped me get started, its' a few pages but if you check it out i left plenty of pics on how i was able to meet the criteria .

but from what i am seeing, your airFlowPerRev and load is a bit high, Ft looks good, you may have to adjust from your fuel while tweaking your maft sliders also.

Yea I read through that when it was first posted. I used those to get where I am now. I think I am going try another o2 sensor. My fan stopped cycling as well so it got a little hot last night. After I fix that ill see where I am at.

So you know, it took my o-2 forever to cycle correctly, i had to play around for while. good luck.

My A/f is good in open loop now, no more stupid rich, in closed it runs lean 19-21. the o2 cycles when i hold it around 1-2% TPS although it revs up and down when i do that.

New log, Seems to run fine, but stutters under acceleration. IF you see after a rev it runs lean. Any ideas? My other car is down, if I don't have some input after I cook and eat dinner, I am going to swap back in the stock injectors and see if I can tune that easier.

Enable narrow band O2 sim.

If its stuttering under acceleration, then adjust your Throttle tip-in under the direct access tab.

Enable narrow band O2 sim.

Kind of hard to do when he doesn't have a WB hooked up.

If its stuttering under acceleration, then adjust your Throttle tip-in under the direct access tab.

It's stuttering under acceleration because nothing is calibrated...not even basic airflow according to the second log. Changing the throttle tip-in at this point would just muddy the waters more.

OP -

1). Please attach your logs to your posts directly; not through a 3rd party file share

2). You need to go back to square one and get your fuel and airflow properly calibrated.
