I have a 07 M8 with a 09 ecm, older ADA boondocker box with the external EBC, kit is a OVS based race gas running a water to air intercooler. Trouble i'm having is my tune changes with elevation even with the EBC set to auto for elevation correction at 1:1. I can tune the sled in 5500-6500 elevation area and it stays pretty consistent until around 9000-10,000ft then it goes lean under boost. I tune it for above 9-10k ft and it's pig rich below 9k ft. When I ride in a area were I easily change between that elevation range it's a real pain in the ***. I tried my original 07 ecm that was flash to the 08 update with the same results. I notice on my stats screen the pulse width is way lower in the upper elevation and I have to really fatten the PSI maps up to keep it from going lean above 9k ft. Anyone else have this trouble with this? I know this setup is old and most guys that had it probably forgot some of the problems.
