Hey everybody. I'm about to get my car started for the first time after building the motor with 9.0:1 compression pistons. I'm running straight 94 octane for now, with an HX35. I don't have the map available right now, but I had the car running well on stock 8.5:1 pistons up to 12 psi on a fairly conservative timing map that I built off of a stock evo 8 map. AEM infinity 506 ECU.
I'm wondering where I should adjust my timing map and by how much roughly to start safely. I'm assuming the low load portion of the map will probably be fine knock wise? But I'm not sure.
Is there anything else with the tune I should expect to adjust for the higher compression like fuel?
What about startup timing and fuel, any tips? I was having a bit of trouble getting the startup tune right before. (Crank, crank, fire, crank, crank, fire)
