So I uploaded a test tune a couple weeks ago, and then... Life. SO I've been driving on this tune the entire time, mix of city and highway. At this point I'm assume the stored BLM's are pretty spot on for a tweak and re-test. Is there anyway to read them out of the ECM with an APU1 or should I just find some time and go for a long mixed drive?
See sig for ECM info if that matters.
thx
