So I am trying to do some street tuning on my talon to make it driveable till I put it on the dyno. Right now just breaking in the motor and breaking in the clutch. All my mods are listed in my profile
So here is my problem I cant seem to get the afr to hit there target air fuel in ecuflash. Ive tuned before and in the higher load cells in the upper rpm range are right now at 10.7 and the my wide aem wideband is still reading 10 to maybe 10.3. As I have leaned out the cells the car is breaking up a lot less and pulling harder with no knock. When I have tuned before on evo's if you put like 9.5 to 10 in the cells under boost the ecu would always hit 11's . So its aiming for 10 and hitting 11. In my talon using ecu flash its over shooting the numbers I put it in. I have never seen a ecu over shoot the number , only fall short. Would adjusting my base fuel pressure help this. or do I keep just upping the afr's in the cells till im logging mid to low 11's in my logs.
Exactly what happens punching gas at like 2k afr's go to like 15.5 and slowing tapper down as I am coming into boost around 4K and pulls 22psi all the way to 8K . Once I start hitting boost afr's tapper down nice and smooth , but just pin down at 10 to 10.3 which I know is really rich and I don't want to wash down my cylinders on a fresh motor. Like I said I keep upping the afrs in the cells and its getting better.
