And what did they offer as a explanation why this happens. The T5 compensate for high altitude and it will run lean? What is it compensating for?
Why will it run lean, logically thinking it should be the other way around.
T5 does calculate the fuel based on MAP, manifold Temp and the "known" VE.
Later of them will get worse, ie. filling is worse = less O2 in the engine.
Temp is more likely to be higher, ie. lowered comprssor efficiency.
In both cases you'll have less O2 going into the engine and the results should be fat instead of lean if T5 does nothing.
I also cant get it through my head how it would end in a lean situation if something goes through the lambda loop and cases corrections to maps.
