I know this is kind of an old thread but I am trying this out on my 91 GMC Full size Jimmy. The standard bin is the ARJT and I have modified with the HW lean cruise and ESC as per the instructions on this thread. When I did a bin differences and even noted the which I though appeared similar to what was posted here. However; when I loaded the ECM I immediately got a rapid flashing Service Engine Soon light. I tried the load on several different 512 chips with the same result. The standard ARJT bin works fine. I would take any suggestions at this point. I have uploaded my modified bins as per these instructions for reference. I am just trying to apply the HW lean cruise to the standard ARJT bin at this point and data log at a later date for fine tuning.

Thanks in Advance,
Steve
