that didn't work, anyone in the area that would have the capability to reset the adaptive values? I really don't want to pay the dealership $150.

Autologic, Faultmate, Nanocom, Lynx, Hawkeye, can reset adaptive values as well. Ultragauge can not. The only cheap way is to get someone else to do it.

What are you trying to fix? I think maybe you did reset you adaptions but it didn't fix anything because that's not what's wrong with your truck.

I don't think the adaptive values can be reset by the method he performed. I say that because a local Rover tech and shop owner reset mine for me twice, for free. I have to think he would have saved both of us the time and just told me to touch the battery leads together after being disconnected.
I don't ever plan on owning another AEL D1 but I guess I'd still be interested to know if the touching leads method works for sure.

It will fix some fuel issues and close throttle position will be learned so the idle will improve
wouldnt just driving around cause it to average out the old values with the new values and arrive at the same adaptive value? I think the only benefit to resetting would be to speed up the process, or if the adaptive values are so far off after a repair that it wont run

I've tested adjusting Long Term Fuel Trim manually with diag tool and it hasn't reverted to previous value in 6 months of driving.

I have to do it if someone changes a tps sensor sometimes. The biggest thing that needs to be done is relearning closed throttle position before you set the min idle . Like when you do it right and want the iac counts to be between 9 and 21 or whatever the target counts are
