Injector Pulse Width
InjPW vs. Fuel Mass - hopefully your injectors provided you flow data to fill this out. ID injectors do. If not, you will have to do some math versus a stock injector to get you a baseline. Not ideal but sometimes the only way.
Fuel Mass vs InjPW - inverse of the above table
Startup InjPW
Startup Base - cut these in half by multiplying entire table x 50% or 0.50
Closed Throttle Mult - cut these down by 17.5% to start by multiplying entire table by 82.5% or .825
Min InjPW
InjPW Min - just know this usually is lower than the stock injectors if your injectors are aftermarket, though each injector is slightly different. I have .152 for ID850s. Hopefully injector company provides this to you.
WOT Thresholds
WOT Pedal Thresh - set to 3.300 volts
Power Enrich
FA Power Enrich - set this table to be your WOT fuel air ratio. Math is (1 / Stoich FA + FA Power Enrich) you want. Or inversely if you know your AFR you want, plug it into this: =(1/AFR)- Stoich FA (not AFR). My stoich is .067 or 14.9, so for me I wanted to command 11.6 AFR under boost so =(1/11.6)+.067 = FA of .019. I put .019 to all the rows in the FA Power Enrich table up to the .75 pressure ratio row, then I scaled it to the equivalent of 13.5:1 by the top row. This blending helps the transition when going from cruising to WOT.
Fuel> Cutoff, DFCO
RPM Limits
You set these to be what you want, factory TCM and MTCM is set to 6700, if you have factory or MTCM you are limited to 6500 here or you will hit limp mode.
Torque Reduction - Rescale left side to be -250,-200,-125,50,0 and set to 100,100,50,0,0 for percentages. Gives you a "soft" rev limiter where factory will just bang on it pretty hard.
Fuel> Open and Closed Loop
Closed Loop
Coolant Temp - set to 32*, factory 14* makes no sense, risks a frozen block trying to run in closed loop? Use this also as your toggle for Open and Closed loop for VE tuning
Closed Loop Enable
ECT Rear - set to 374* as you don't want to ever be using your rear O2s for fuel trims
Fuel Trim Cells
Idle VSS - I set this to 5mph, you can leave stock and see if you have any fueling issues rolling around at slow speeds. If you see weird fueling right between 2 and 3 mph then come back to this.
Fuel>Transient
If you are stock intake manifold, leave this alone. If you have a roots blower, this should be bumped up but not sure exactly how much. try 12.5 to start.
