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?

I was also told by the COBB guys not to run the aggressive map until my spark plugs were changed because I was getting a missfire on a cylinder with23k miles on the car. |

I find it hard to beleive that the DME no longer adjusts for lower grade gas with the cobb in place. The knock sensor and pulling of timing is a basic function of how the DME works. Agreed you should run the recomended 93 with the cobb but I don't beleive that cobb would have removed this basic function from the DME when they did their tune.
