Well long story short I’m having a hard time getting a base map written for my skyline with tuner pro. Figuring out the kvalue and latency are what’s really killing me. I converted the car to e85 with an aem e85 pump and 850cc flowed injectors but the damn suggestions in the tuner pro xdf notes are way off,the car won’t even run with them set as suggested. The injectors are correct for the car and I have it tuning half decent now by guessing. But still. Is there a proper formula to figure out the k value?
