Dave, Everything I had read online referenced the 3e xdf, which I could not find except on Tuner Cat. I also had noticed the same 3f reference when I read the hex file so it made me doubt the 3e information I had seen... But when I load the $3f xdf I found this is what displayed for VE and spark, certainly not right.

Also I come up with a totally different prom ID that you show. What tool are you using to get the PROM info that you screen captured?
I am not opposed to using TunerCat as long as the 3E will really work. Since this bin reads 3F, I am not sure? At some point I will probably take this to S_AUJP, but figured this was the quicker way to get it rolling.
I wonder if the $3F adx I have is a good one? Do you now if there are multiple versions I could check out?
Sorry for all the random comments and questions, a lot of pondering going on here this morning!
