VAFC 2 installed with PAW calibration what to do???

OK so I've installed ste's VAFC 2 in my ATR, went into the setup process and it's all already been done with fuel corrections from when he had it installed at PAW.

The question is, do I reset everything to default or leave it as is?

The motor it was tweaked for was almost exactly the same as mine and the VAFC is only changing the fuel trim...

Take it to a rolling road and see if it is running right with the vafc running, until then take it easy?

Fair enough, it'll be going on the rollers on the dyno day.

will be getting a wideband O2 sensor in the next couple of weeks so will have a much better view of what's happening then...

as long as it doesn't lean out your fine

I'll take it up through the rev range tomorrow, PAW wouldn't have tuned it to lean out. Altho all motors aren't the same it shouldn't be that far out.

Altho, just remembered it was on obd1 injectors not obd2 but that shouldnt effect the afr should it?

wouldn't have thought so but you don't know what the differences are between an obd1 map and an obd2

True, I'll have a drive tomorrow and take a look at the correction numbers. May just take them in a little until I can get the wideband O2 sensor on it
