AccessPORT, maps and octane question...
I'm trying get some information on Stage 1 aggressive maps for AccessPORT regarding octane. The stock ECU can detect the octane level and adjust. For instance, if I put in 89 octane it will automatically detune itself to avoid damage from pre-ignition. If I run the 93 octane aggressive map and end up filling with 91 octane gas because 93 was simply not available in the location I was in would the reprogrammed ECU be smart enough to detect the drop in octane and adjust?
