Also are you sure your running the right afr or is it just super rich and that's why its using so much fuel.
Well, yeah, check the AFR table, it is from the same datalog as the injectors: INJ_DUTY vs AFR match.
I thought of making the pressure 4bar but then I noticed the Nismo FPR twists together with the screw (it's crap). I changed back to the VE stock FPR at 44 psi.

This is true and since my battery is in the trunk voltage may be lower than normal.
OK, I know I'm not pushing 226WHP
, but something weird happens with my tune (and/or something is wrong with my car
). If I use the base E60 bin Calum made, it goes so lean at high rpms is not even funny with the 12AFR values in there. I have to fill the fuel map with 10AFR values so it gets near 13:1 actual AFR.
What I did in order to get fuel maps AFRs to be more similar with actual AFRs for ease of tuning is to alter (add to) the VE Map without changing the K Value so cruising is not affected. Up to 6800 rpm, 12.98 in the fuel map gives me around 13 actual AFR
. At 7200 and above it just doesn't and I still have to lower it to 11s to match 13 actual. This has some cons:
1. Injectors are maxing out (but not before altering the VE Map and getting the same 13 Actual AFR)
2. B_Fuel Schedule tops at 255, meaning all ECU fuel calculations are maxed out.
3. MAF Voltages read higher with this setting (MORE POWA???), despite timing and actual AFR curves (aiming for 13) are practically equal.
