First scan is with the P59. I've been logging some spark retard 3600 rpm and lower. This timing is lower than the other scan(kid drag 3) which I didn't log any spark retard. My flex spark adder is 4 degrees. There might be something I'm missing but kinda feel I'm pulling more timing than I should have to. Could be wrong.
Also I've been trying to dial in my ve or at least get it somewhat and then let my stft take over but it seems to be always wanting to target 14 or higher when cruising. When I get into PE and then BE it makes a huge jump and my errors are far less. This is with 40% alcohol and I think the scanner was saying I should be targeting 12.4 give or take. I've already added fuel a couple times but with no change.
