yep gotta zero that guy out unless you want to go full flex fuel capable.What else is strange is with the SD2 chip he is adding about 5* of timing at WOT with the flexfuel option If you look at the spark adder table srait from Eric or at least mine came like that
That is what screwed me. I had the timing I wanted in the table, then after going over the log, saw 25°. By then the cooling system was pressurized and the gasket was done.What else is strange is with the SD2 chip he is adding about 5* of timing at WOT with the flexfuel option If you look at the spark adder table srait from Eric or at least mine came like that
Believe it or not I start even lower than that when over 80lbs/min and on pump e85. If it's e85 out of a sealed can that is mixed with high octane I have other strategies I use. I'd rather be chasing timing rather than pulling it. The cylinder pressure is the problem. Timing equals cylinder pressure. I agree with you based on your high egt though id want 100% verification of base timing and to know exactly what fuel i was in the car before I was questioning my timing strategy. I had an engine that wouldn't run for crap with low timing. It was 7.5:1 with a crappy set of iron heads. It needed 22-24* of timing or it lost a bunch of power. I had about 200 dyno pulls on it so I know I had the timing dialed in over the entire map. The quickest it ever went was 10.60.Copy that I can see where u r coming from guys as every motor is different . So where would you guys set your timing to with 85% ethonal to start tuning 17-18*? And sorry Anders for jacking your thread up but all these guys know a lot more about tuning these motors then myself so disregard my statements .
