Tuner in Training
I am going to be attempting your open loop maf tune. If I get this right when all said and done with the tune I want to set
PE enable>delay vs. tps = zero out which it is stock
PE enable tps>hot = where I want it 20%.
The base afr vs. ect to 11.50 since I'm supercharged to be safe @ 11.7 now
Zero out the add vs. rpm table.
What about the add vs tps? Do I leave this zeroed out? Are there any pros or cons of having this and the add vs rpm zeroed? Just curious on what these changes do exactly.
THis is on a 99 GTP (s1x,48#,3.4,headers,cb)

I would leave it 0'ed out. If I find the an engine is going lean at all in the top end then you need to hook up the wide band again and make adjustments to the maf table in that region to get your desired AFR. There are tuners that use only that table to tune fuel and leave the MAF stock. I say, choose one or the other and stick with it. Having both tables interact to tune that area is a pita in my opinion. Just make dam sure that a WB is being used to adjust your MAF table in PE. Just telling the car to go to 11.5 in desired AFR wont cut it, it has to be verified with your WB. 20% TPS for PE is a might bit low too I have to say. You will bounce off 20% with minor TPS changes at highway speeds. PE that low is going to kill your NB Sensor pretty quick, and waste a lot of fuel in the long run. Try tuning PE for the area of 30-35%. Just my 2 cnts
Ok I am having some issues, I must be missing something, because when I attempt to do my maf tuning, I get nothing but 0's across the maf board.
Here is a scan, and more importantly my file being used.
Any help is appreciated!
