    Yes, some more information can be found here and here

    I went to an LSJ TMAP sensor and wired in the temp sensor correctly. I've been trying to get VVE/Dynamic Air to work, but haven't had luck....

    I relocated my IAT to a 2.5 bar TMAP on the supercharger maifold. I was disabling it by setting the maximum hz to 100. I think the timer was preventing it from actually faulting though.

    I think you're onto something though. If it's not failing, it could mess with the VE tune. I set it to 20 seconds to see if that changes anything. Should have data tomorrow. Thanks!

    Thanks for the responses. Much appreciated.
    I checked MAF ERT tests vs stock and they are all the same. My motor was equipped with SAI, so it could be different than other models.

    I'll confirm...

    A solid tune shouldn't have a backfire. While I was tuning I had a real bad one. Disabling DFCO completely got rid of it.

    Get your injectors, MAF and VVE tuning right and it shouldn't happen.

    ZRJO, I replied in your other thread.

    As an update, the original tune from the 'tuner' was alright, but required quite a bit of touchup. This is partially my fault because of the vac leak and only...

    I'm sorry I'm not able to open your tune because there's a version issue. I've had this in the past and haven't been able to fix it.

    Your log is showing adding quite a bit of LTFT. Are you logging...

    You can absolutely use my tune for whatever. I've since found it was tuned with a vac leak and I'm redoing the MAF and VE tuning to dial it back in. I'll have a much better baseline in a week or two....

    I tried turning on the coolant pump in VCM scanner and no relays came on. Pretty sure mine isn't using the right outputs from the ECM. May still be possible.

    I tried updating my HP Tuners and it still won't let me see your tune. It really sounds like the MAP isn't scaled right. Can you tell me what the map linear and map offset are?

    Couple updates:

    Changing throttle area scalar from about 1600 to 2950 cured Rev hang issue.

    I'm dialing in PE parameters. Been raining here a lot so I haven't had much time. I have to upgrade...

    I can't open your rune right now, but I had to change my throttle area scalar from about 1600 to 2950 and that fixed my hanging revs. Double check that. Also, check your MAP sensor linear and offset...

    Which MAP sensor are you both using? And is the ecu correctly scaled for it?

    Let me know if you find out. I have a supercharged LAP and would like to find a dedicated relay for the coolant pump and heat exchanger fan rather than piggybacking off the fuel pump.
  16. 2.2 LAP Supercharge Tune - Is this how you would do it?

    Car is a 2020 DF Goblin with the drivetrain and electronics from a 2009 Pontiac G5 2.2 LAP motor. Car ran N/A for 2 years before supercharger install.

    I added mechanical supercharger components...

    I'm not able to open your tune file. It says unsupported version.

    I just supercharged my 09 2.2 in a Goblin. How did you wire in the LSJ throttle body? Did ZZP send an adapter?

    I just did this to my 2009 2.2 in a Goblin. I used 42lb Bosch green injectors, so my numbers are different.

    Changing this table got it to run with the new injectors:

    I have not changed...
