I haven't answer you correctly as you maybe understand that I changed the voltage target and have no more problem... No, to be more correct, I changed to 0.45v and then it was also to about 15-20% short term correction... (with long term also)
I compared two datalog records to understand what happened.
I tried to attached here my calibration .re4 but it's not allowed. which was tuned in open loop and then turned in closed loop operation. so I attached two datalog:
the datalog file "Autoroute1" was recorded open loop. If you check at the point with the cursor 46.36 I had 3997rpm, 566MAP, 14.35AFR, INJ 4.63ms and DUTY 15%.
the datalog file "closed loop2" was recorded closed loop with the same calibration. If you check at the point with the cursor 34:498 I had 4023rpm, 583MAP, S.TRIM 11% and already L.TRIM 14%... with almost the same INJ 4.70ms and 15% DUTY. and looking at my AFR gauge between 14.4 and 15.2 (swinging)
What do you think? It's strange?
As I said, I then tried to compensate the overall fuel trim for about +7%. (I was at -5% in open loop so I set it to +2%)
After that I had the same numbers at WOT (13AFR) but I had to richen the Idle and column 1..
Did someone already has this problem??
Thank you for your help.
