    Do you have a wideband on this?

    You need to remember that you put this into speed density, so it's only running off the low octane timing table. Those really low values in the timing table where...

    The tune posted above should never enter closed loop on it's own. If the closed loop ECT vs IAT is set to 284 degrees, it should never enter closed loop. Same with having the LTFT set to 284 and the...

    HP Tuners themselves are the ones that set the credit amount.

    That table is on newer computers.

    This P01 won't have that. You can change the open to closed loop temp settings and also change the STFT and LTFT settings. It looks like you've set the tune up...

    Well, you kinda only have two options.

    Either buy the MPVI2 without the PRO Link features or buy it with it. You'd need to make that judgement call to see if needing the PRO features is worth it....

    It's going to take a good amount of time to adjust the fueling with a wideband o2 sensor.

    Is this a cat-less setup?

    Where is the wideband installed and can you do a open air calibration on the sensor? You also forget to disable COT.

    More fuel means to add and less fuel means to subtract.

    You add to the VE to add more fuel and remove from the VE to subtract fuel. Same goes from the MAF table.

    It's not a PE problem. The commanded AFR didn't change, so PE is working as it should.
