  1. How do I increase torque request on 2014 ATS-4 2.0T?

    Hi All,

    I seem to be hitting a brick wall here.

    How do I increase torque request on this 'puter? I have gone up to 500 in the pedal torque request tables at the 3 highest pedal positions with...

    Ancient thread, I know, but I don't see the software download on the page you linked to. Looks to have been redone in the last couple of years.

    Does anyone have a current link to the software?

    What's not ready is closed loop. Therefore you're in open loop until the conditions for entering closed loop are met.

    Same here. On a 2015 Whippled SRT GC.

    I have a small throttle oscillation due to exceeding expected tq, but I'm dialing that out.

    The real issue is that 2500RPM momentary cut/ hard stumble.

    You still have an issue if you can't tell the ECU there's more than 195kpa MAP with a 3 bar MAP sensor. Did you input the correct data for the 3 bar sensor? Is MAP correct with key on engine off? I...

    Well, regardless of whether you've had the max MAP as high as 250kpa, you're running more boost than 195kpa, so that's got to change. And P0108 makes more sense.

    If you have a 2.5 bar MAP sensor, and you're only hitting 2.15 bar or so, you're not maxxing out the MAP sensor. Which I think is what you were trying to test when you increased the max MAP voltage...
  9. Do NOT use the Duramax 3.3bar 12623671 MAP sensor on small cam builds!

    Hi All,

    I was having difficulties with a 3 bar SD OS tune on a 5.3 turbo build with a stock cam. Idle was unstable and trims were all over the place. At higher loads all was ok.

    With the above...

    More searching has led me to believe the MAP sensor itself doesn't play well with low absolute pressures and therefore voltages.

    I apologize. I see now that I didn't mention that I was running it in SD for now.

    It is currently SD only, so I can dial in the VE tables. Yes, it is a bit blocky, but, 1200 RPM and lower aside,...

    Baro changes while engine running on 3bar OS

    I've been pulling my few remaining hairs out over this for awhile now.

    The car is a turbo 5.3 with blow-through MAF and the 3 bar OS. The engine itself is stock, and idle issues and...

    I do NOT have any codes that arise from this, simply the MAF fail status bit goes red and says "Yes."

    What could cause a MAF fail on LS7 E38?

    Hi All,


    The car in question is a 2008 Z06, running the stock OS. It's already scaled 50%.

    Dynamic airflow is set at 200/100RPM, so MAF only for now.

    The "MAF Fail High" is set to 14500Hz....

    It won't be left like that. I posted this up pretty much stock because the scaling glitch didn't let me get any further than pretty much free-revving.
