I'm trying to research the differences in the 14CUX ECU and I'm not finding much information on how to tell the difference between them by the code or model number. I found that 80505 is for 3.9 cat and 80506 is for the 3.9 non-cat. My assumption is that this is catalytic converter equipped. Also, I know there are automatic and manual transmission specific ECU's, but I don't know how to tell the difference. It could be the "A" designation as in 80506A. Anybody out there that can shed some light on this for me?
I've read about ten threads and it sounds just like stated above. They all pretty much work, but it may be necessary to have the unit reset to learn the new truck.
I'm getting one to add to my spares and would just need it to get me home. Dont really care if it throws codes.
Thanks guys.
85 MPH speed limiter would not have much of a chance to kick in for me either. I had my truck cruising at 70 last week and it caused my 10" side mirrors/airbrakes to tip back. It was very smooth, but I don't see it going 85 in comfort.
