OBD1 GM PCM tuning, who does it?
I have been searching in vein for a shop that can do OBD1 tuning for my GM 4.3L TBI. Has anyone got a bead on somewhere I can take this rig to get properly setup? I am probably capable of getting all the stuff together to do this myself but I'm a busy man and I'd rather not have to learn how to do this. Any leads would be helpful.[cheers]

reeceman on here or dirka dave could prolly help ya out, i know they both have scanners, im not sure if they have the obd 1 stuff but you never know,

also, google is your friend :p

try this and then just google your engine code for the obd1 system

I can get codes no trouble, I built a switch into the harness when I built the whole thing just to get fault codes on a whim. What I'm looking for is more than a scanner, I'm looking to change the programming. I'll give them a shout and see what they know. Thanks

Well u want a tuner then or someone to make a tune for u, an OBD reader won't do that

My scanner will read obd1 codes

4skin 02-22-2017 03:33 PM

Read and tune are two different things

Reeseman 02-23-2017 08:55 AM

Ya I know. I have a buddy that can do GM tunes too

Reeseman 02-23-2017 08:56 AM

Not much you can do with OBD1

Happypants 02-23-2017 09:00 AM

Andre could prolly make a
Tune for him

Reeseman 02-23-2017 10:42 AM

Nope he can only do 97 and newer.

I believe I called indy-speed before but I may be mistaken. I will try them again. From what I have found online it definitely seems like an OBD1 ecu can be tuned, just nobody seems to do it anymore understandably. I am looking into other options like finding a manual ecu. I have been trying to determine the correct part number for one.

Happypants 02-23-2017 06:27 PM

Let us know if u find anything, reese, mabey something like this, assuming he finds something, might be worthwhile on Corey's s10 to utilize that power if the RBI system falls flat on its ass lol
