Iso prom chip and maybe ecm for my truck
I have an aftermarket Jet prom that came from my 91 with a 5.7 and a 5speed manual. It has the selector switch so you can tune for different power levels and a valet mode to limit it to 10MPH. You can also turn off the ECM to stop it from being stolen. I pulled it when I replaced the engine because I used a different camshaft and I didn’t think it would work. I had a custom chip burned for my needs.Iso prom chip and maybe ecm for my truck
They're all ODDI with an EPROM but, the 94 & 95 are probably the 16197427 PCM (there are others) if you have an automatic trans, other ECMs for a manual. The chips are 28 pin instead of the 24 pin earlier ECMs have. 96+ are "flash" PCMs with no chip. YMMVI thought 94+ ecms were different. Maybe @PlayingWithTBI or @Schurkey would know?
