Boost Target Changing


Electredge

Recommended Posts

I have all the trims zero'd out, using only 1 target table

 

Boost Target Table has boost set to 200kpa at 75-100% Throttle and 0kpa at 0% Throttle

somehow between gear shifts it changed boost target from 200-244... but if you look closely it appears to have offset the entire boost target by adding 44kpa to everything... after letting off the 3rd gear part of the pull you can see it doesn't fall back to 0kpa target as it should. 

let me know if anyone has any suggestions... the ecu log is too large to post but I will attach the map on the next post

Can you update to the latest firmware and try to reproduce.  Even if you set your target lower for testing it should be a valid test.

I found a similar bug noted in our system where if you passed through a 0 target in your boost target table when there was a negative trim applied it would add trim to the target after that point.  During that gear change you do move through a zero target cell so I think this is related to the same bug that has already been fixed.

seems to have fixed it, I also got rid of the 0 target as well just in case but no longer having the issue. 

Thanks Adam
