I am working on a 3 bar Custom OS on a 2002 Express Tune.
What is confusing me is the table axis. Lets take the high octane spark table. It is comparing Engine Speed (RPM) to Cylinder Airmass (g).
This is a speed density OS only so shouldn't it also compare RPM to MAP as there is no MAF sensor being used by the ECU.
Maybe I'm just missing something.
Any help and explanation would be greatly appreciated. The VE table is RPM vs MAP like it should be.
