I started my tuning experience. I have all the software possible, lt1 edit, datamaster, freescan, and I have a wideband in the car. Mods in the sig. I have chosen to go with a open loop tune only, do to the size of the camshaft. I first set the injector offset for my SVO 42's. Then went into the OPEN LOOP AFR vs. LOAD vs. COOLANT TEMP, and got the car to idle inbetween 14.7-15.1, with about 30° of timing. Tomorrow I am gonna go out and do some part throttle tuning. What should part throttle AF be roughly? High 13's? Now should it be mid to high 13's no matter the kpa, as long as I am on the throttle? Thanks guys!

 

How did you specifically set the idle fuel mix via the open loop afr/coolant/load tables without affecting cruise fuel ratios at the same map value?
