2001 Cobra no LTFT

I am having an issue with getting the car to use LTFTs. This has been going on for about a month. I flashed it yesterday and all worked as it should and since all seemed to work as advertised, I made a minor change, flashed the car and they were not working again. I went back to the previous working tune with no success. I drove the car for about a hour with a lot of highway use so there was ample time for it to repopulate. Has anyone ever had this issue before? The O2 sensor are new Bosch units.

If your fuel is dialed in then kams will remain at 1.

post the tune file and someone can check it out to make sure you don't have kams disabled.

They are close, but not that close. when they were working I was getting a LTFT at cruise of +/- 1.2% and more at various loads. Updated original post with tune file.

All looks well.

The stock tune only allows kams to update between .15 and .45 load. You can set the adaptive update rate table to all positive values to get it to adapt through out the range if you want.
