SD Fuel Tuning
Do I lower the numbers or raise them on the two ve tables to take away fuel? I'm at a 1:1 ratio right now which is causing me to be in the 10(AFR) when in boost.
Also how do I know what KPA range is equal to VAC or PSI? Can you log it?
Running a omni 4 bar and using the fuel temp sensor.

100+kpa = positive pressure
Log kpa at request ID 38 (Map sensor adress) and set the formula for the omni 4 bar which is: x*1.63345239
For the ECU, VE is a direct multiplier to fuel pulse width: +5% VE = +5% longer injector duty cycle = more fuel
