I need help solving a very annoying issue with cruise control. I have also posted this on the HPtuner forum. Any leads on someone that could help would be greatly appreciated!
I have a 1987 60 series that I have swapped in a 6.0 LQ9 DBW setup, I kept the stock 5 speed manual transmission (H55f). I bought the wiring harness from BP automotive and have a Dakota digital cruise control panel.
Over the last several months I have spent an exorbitant amount of money and time trying to diagnosing the issue. Currently, I have cruise in 4th gear but when I change to 5th the PCM locks out cruise. As you know, the transmission is analog, so I cannot figure out why cruise doesn't work in 5th gear. BP automotive did their best and over the course of 4 months, we exchanged 100+ emails with several iterations of tunes but they finally threw in the towel. I can supply a copy of the latest tune if that would be helpful for anyone. (I can't attach the file because IH8mud doesn't recognize the file format)
I would be more than happy to pay a professional to take a look and help me diagnose the issue.
thanks for any insight.
