  1. So I have been able to work around the lean out,...

    So I have been able to work around the lean out, by setting the dynamic airflow enable to around 2000 rpms, it will slightly lean out but goes above 2000 rpms quick enough for it not to lean out...
  2. So I finally got my flex fuel sensor installed, I...

    So I finally got my flex fuel sensor installed, I couldn't get it to fit and made a convoluted mess of fittings and hoses but its in there and wired and and virtual flex fuel is now disabled.
    ...
  3. Yes, thanks, it seems this is the way it would...

    Yes, thanks, it seems this is the way it would work too, but with mine you can butcher it pretty bad and it still works, now if you zero it out or max it out, then yes it will throw a fuel pump flow...
  4. Does anyone know how the fuel trims work on the...

    Does anyone know how the fuel trims work on the FSCM control loop? They appear to just be multipliers as both short and long term trims I usually see in the 0.89-1.01 range. But they just don't make...

    What platform is this on? Camaro? I didn't think we could full flash any FPCM? Only write regular calibrations?
  6. Has Anyone Gotten Successful Control Over the GMT-900 Truck FPCM?

    So the CTSV and Camaro people are able to control their FPCM's so they can get the maximum duty cycle and flow out of their pumps.

    However, the truck FPCM (20898936), which has included stuff...
  7. Sorry I mean to say calculate not extrapolate,...

    Sorry I mean to say calculate not extrapolate, you hit extrapolate to load the new generated coefficients from the edits you just made in the VT editor. And yes like hjtrbo said, we have been dealing...
  8. You are exactly right, I have been trying...

    You are exactly right, I have been trying millions of things trying to figure out why my airmass is so high, it is also high at full manifold pressure before boost kicks in, for whatever reason...
  9. . You have to increase the MAP kpa just like...

    .
    You have to increase the MAP kpa just like you did for the airmass to show tables with an increased MAP range.

    The virtual torque calculation isn't 100% perfect as there is some numerical...

    We are hoping you have the answers to your questions being a GM engineer haha, it's baffling some of the things you see in the tune file.

    And about all the extra ethanol parameters, I copied the...

    Ok thanks for the info.

    I have been fighting a 2-3 WOT slow shift. I just reset the adaptives after flashing CTSV shift times in. Once you preset it to fast learn mode it will click off about a...

    So I did some visual comparing of my stock L9H torque tables to a LS9 ZR1 calibration torque tables, and in the WOT areas around 2000mg airmass they appear to be about 100-200 ft-lbs lower on the ZR1...
  13. Also for those of us with truck E38's, I wonder...

    Also for those of us with truck E38's, I wonder if we should just copy the torque tables from a LS9 calibration? or at least a LSA? I haven't really looked at one in depth but I would think they...

    The virtual torque editor should instantly display the new set of tables with your limits, look in my screenshot in the above post and see where I cricled in blue, thats where you need to increase to...
  15. So yes I think you're right, the stock torque...

    So yes I think you're right, the stock torque tables work and are fairly linear through the stock torque range. However, once we double the torque, the small little variances in the stock torque...
  16. You need to disable these checks once you go...

    You need to disable these checks once you go boosted, the ECM is expecting a certain amount of airflow and when you go boosted and increase the airflow past what's normal for a NA motor of that...
  17. As for your original question OP, which it may...

    As for your original question OP, which it may not even be what you were asking, but, I have heard people comment on how you have to "tune" the virtual torque tables when you go FI and start making...

    From a HP Tuners marketing and business standpoint I clearly understand and get it. If they can figure out a few tables and parameters for a completely new vehicle, like the Frontier you were talking...

    I wonder if HP removed them because they are feeling more "heat" from the do-gooders at the EPA? Makes you wonder?
  20. One thing I don't think I saw on there is changes...

    One thing I don't think I saw on there is changes to make if your cam has a bigger fuel pump lobe. So you can scale the row axis (y-axis) of ECM 17062 "Fuel Pump Leading Edge Angle" by the percentage...

    My only guess could be that TITM is maybe "tip in torque management"? but that doesn't really make sense because I get TITM at WOT right before the spark timing torque reduction. I also get TITM...

    I couldn't get mine to work at all, I think it may have been a GEN III type control, but they took it out, along with AFR control, in the GEN IV stuff and vehicles. Probably a EPA mandated thing.
  23. This is how mine is stock and I verified it with...

    This is how mine is stock and I verified it with some other stock tunes, but I will change it to go faster.

    I've also tried turning off desoot mode and different combinations of the enable temp.

    I promise I tried haha, but I used one of those stupid racetronix fittings to use to connect to the stock fuel line and it left me stranded on the road and almost started a fire because the aluminum...

    Sorry I keep posting replies but I keep forgetting things.

    I put it back in MAF only (zeroing out dynamic airflow enable RPM) and it still does the instantaneous lean spikes, but it hasn't done...
