Cobb AP map qeustion - 91 vs 93oct
I just bought STG2FXT's car and in the process of driving it back across the country. Once I crossed into Missouri, the max octane shifted down to 91. Charlie has the AP set at Cob Stg 2, 93 oct. He gave me the AP as well, so I can change the map if needed. However, given that I am in a hotel in Oklahoma City, I really don't want to risk f*ing things up mid-way through my drive back to SF.
I am now on my second tank of 91 oct, and am noticing lag in the power, but no bad detonations. I still have another 1600 miles to go, so I am looking at 6-8 tanks of 91 oct until I get home.
What are the detrimental effects of continuing to run the 91? Does anyone feel like walking me through a map update to 91 oct? My smart buddy is currently in SF, and has not played with an AP before, so he is not helpful in this case.
edit: It was brought to my attention that I am an idiot. 2004 FXT Manual.
I just went out to switch the maps, and it said 'done', but it's still on the 93 map. This is a really stupid question, do I need to have the car in diagnostics mode?
