But these newfangled engines with computers are out of my area of expertise.
I have a BlueFire which I take when I pick up vehicles, but I need more detail for some of the diagnostic work I'd like to do here. I did recently buy a Nexiq (not a clone) and I'm looking for the most universal software option to pair with that. Is PF-Diagnose a good option? Is there a better one I should look into?
If you want to get a Pro-Link scanner for Detroit DDEC engines, a good way is to buy a complete Pro-Link for old (late 1980's, I think) GM cars that used the same 12-pin connector as DDEC. Because nobody these days needs scanners for those cars, you can get a Pro-Link for cheap, then you throw away the GM cartridge. This will save you needing to buy an expensive adapter for the DDEC diagnostic port. Software cartridges for DDEC I and II and for II and III are often available for not too much, but there was a running change during DDEC II which means that earlier generation cartridges won't work for later engines, and v.v. I've bought all my Pro-Link stuff off eBay this way, and for a few hundred dollars I now have everything I need to scan my engine, including carrying case and printer.
