Hey guys and girls,

I got a new dry-cell Odyssey battery for xmas and had a question about swapping it into my car. I'm currently running Cobb AP stage 2 and was wondering if I need to reflash my my ecu again after changing my battery? Also, should I do the ecu reset while my battery is disconnected? (Press the brake three times, etc.). Sorry if these are dumb questions, my AP manual is at work. Thanks!

Andrew

 

it all depends on how you flashed on the cobb map. if you simply flashed it on, then it will be reset to factory. but if you had the cobb rewrite the ecu, then its the permanent map. this is all in your manual btw, look at it when you get a chance.

 

^^^ +1...realtime maps will get erased, basemaps wont

 

this info is slightly correct. Basemap=flash, realtime=load.

when you marry the AP to the car you're flashing a basemap. Later, you can load a real time over that (kind of a temporary map that doesnt use up the 100 or so flashes your ecu can handle in its lifetime). When you disconnect the battery, the realtime map will go away and the car will revert to the basemap that is on the ecu. This is the same effect as if you selected "rest ECU" from the AP menu or if your battery died. Hope this helps you

 

Thanks guys. When I got the AP, I married it to my car and flashed a stage 2 basemap, so it sounds like I'm good with switching out the battery without having to reflash. I appreciate everyone's help

 

to make it clear for everyone, installing AP=flashing basemap. if you have the ap installed, you have a non-stock basemap
