We can make programs for every 10% of of Ethanol content, this allows you you to select a program based on the gauge reading. We have good base programs to offer this for Nismo 740cc injectors. The following would be a typical program to make this easy.
0 = no start program 1 = E10 that is pump fuel 2 = E20 3 = E30 4 = E40 5 = E50 6 = E60 7 = E70 8 = E80 (this would be safe for full E85)
We would provide you with safe boost levels to run.
