I have both my PE tables at 0, im bout to go - on the pe vs rpm.

Im running an open loop tune. I tried lowering my AFR vs map vs temp table and it didnt seem to do anything.

How do I pull fuel via the MAF?

 

You multiply. IE: If you want to add say 4 percent of fuel in a certain cell you scale the number and put in 1.04 for 4%. and to take away say 4% you scale the number again and put in .96 Im not sure if this makes sence but if you need me to claify I will.

 

do you have a wideband? are you rich all over? first thing i would do is put the car in closed loop, then, if youre still rich, go in and adjust your injector constant. putting in a higher number will lean you out, a lower will richen it up. if you have 60s, try putting 63 in and see if it gets you where you want to be

 

Wouldnt you change the injector if you were lean/rich all over the scale. If its just certain spots your wanting to change I thought you wanted to change the number via the maf.

 

Yes, I have a wide band. With My PE tables set to zero my A/F is still 11.3:1.


Im sort of moving on from this problem and going to a speed density tune.

But for future reference for me, in the MAF table, if I increase the value the car will richen up?

 

AFAIK, the pe tables dont do jack crap in open loop mode.

If you're speed density open loop, fix the target air fuel ratio for that map value and coolant temp and that should adjust it everywhere. OR if its got the same error during cruising, adjust your fuel injector size. OR you can go into the ve tables and adjust specific rpm fueling at high map values. If you still have a maf hooked adjust maf tables in the upper ranges.

To answer your other question if you increase the map value for a frequency, it will richen the car. You're telling it its getting more air and really it isnt, so it will add fuel for this extra air you told it its seeing, even though nothing changed but the value in the lookup table.
