40% too lean when turning to close loop

Post by AECampeau »

Hi there,

We tuned couple cars with the same OPEN/CLOSE loop problem...

After tuning the car at open loop, as soon as we swith the option to close loop, it run 40% too lean and run like #$%#@.

The problem is not only at idle, its doing it at WOT too.

If I switch back to open loop everything is fine.

this problem happened on 3 different car/setup

let me know if someone know what im doing wrong here...

thx

You need to post the calibrations and the datalogs showing the problem.
