I was wondering if one tunes his turbo car at 4000ft above see level what would happen if he drives his car at approximately 50ft-500ft above see level? Would the car run excessively rich? I have a Hondata fuel/igintion map for my turbo H22a, but it was done at 4000ft above see level and I drive at 50ft-500ft above see level. Please advise what I should do. Thanks.

 

I don't have any experience with Hondata, or tuning at 4000ft. But, if it is Hondata, then it should be corrected by the barometric sensor in the ecu. More atmospheric pressure, the maps should automatically be adjusted. The Hondata guy would know for sure. Since it is off of an oem Honda ecu, they're self-adjusting. For more power in racing, it should be re-tuned at the elevation you are planning to race....

As for just driving, I go from sea-level to @8000ft without any drivability problems on my oem ecu....
