See #46 above. When I see data that does not make sense I usually grab a different scanner. Sometimes the data just gets screwed up. I to await your results with the new cable, I think you will find a lot more than the 10 data list parameters that your current scanner gives you.
I’m still waiting for a response from red devil before i purchase the cable
This seems like to much work and I’m
Not good when it comes to wiring, what are the benefits on this swap anyway?
Pretty much just a repin of the harness, shouldn't be too bad should you decide to go that way.Originally Posted by maronielb
It's a more modern PCM than the ECU you have now, not sure, but should have a faster clock speed, and more ram? There are probably more people who are familiar with them than the ECU that you have.
Should be able to turn on highway mode for a lean cruise if you wanted.

To be clear I wasn't saying that you should or shouldn't go with that, but only pointing out that it is a fairly inexpensive option before burning the rig down.
Should you decide to do that, you can still use the same scanner and should be able to use the same aldl cable also. Should be noted that there are not any known factory bins for a 350 and a 5 speed for it, there are v6 i4 and 454 bins for a manual transmission however.
While I'm thinking of it, do you have access to another obd1 GM you can plug your scanner in to for throttle % ?
No need to re-invent the wheel. But we can make it better
Just looked at your first picture of the scanner again, I noticed that the pnp or park neutral position is showing reverse
Does this always show this, does it change when you push the clutch in ?

No it doesn’t sometimes it shows drive/reverse and other times it shows p/n this does not change with clutch depressed or brake pedal depressed. It’s just randomly shows something each time i plug it in. However 90 percent of the time it shows p/n. My neighbors truck is an automatic so i will check tomorrow to see if my scanner changes when i put his truck in gear
I think I’ll keep the computer that i have since i can run the correct bin on it and I’m definitely not burning the rig down i just spent 15k to restore it from the frame up. Yes my neighbor has a 94 I’ll plug my scanner into his truck tomorrow and see what it does
Glad to hear. Too many repairable trucks end up in the scrap yard and are replaced with new trucks that aren't made as good. Well that's my opinion.
