Hello, Newbie from Oregon

**g00se** · 03-20-2021

I picked up an awesome 1994 Chevy, 5.7L, 5 speed manual, C2500 truck.

I'm really loving this truck --only problem is that it failed the emissions test for HC. It does smell a little rich --but there are no CEL codes and my OBD2 scanner won't read live data (and this is OBD1). I'm hoping I can learn from your forum --how to work on EFI/TBI with OBD1 and not only fix the emission problem but also increase engine performance.

Thanks!

TunerPro RT is a good option for OBD1

Thanks Dave! This looks great--and exactly what I am looking for.. I will give it a try!

g00se,

People like RedDevilRiver make ALDL (OBD1 for GM) to USB/Bluetooth that are compatible with TunerPro RT. I've used it myself and it has helped me with a lot of my problems. You just need to figure out if you need the GM 12-pin or the GM 16-pin.

Hope this helps!

Hi Guys! Okay good news --I finally got an ALDL cable and have downloaded the TunerPro software. Right now, I just want to be able to see the live data --so I downloaded the Datastream Definition---which I think should be "A217_0D_v250.adx" --does that look right to you? My truck has a manual so I'm guessing the other two options are for an automatic? They just include Trans1 and Trans2 in the adx filename.

Do I need the Bin file too? Would it be safer to check the ECM to make sure it has 16197427 on it?
Sorry for the newbie questions! I've done some reading but honestly it is way over my head to understand it all.. :-)
