Default Upgrade ESC Question

After going back and forth about whether I wanted to do it, I've decided that since everyone else's having such good results with the upgraded esc module, I'd pick one up. I haven't gotten it in yet, but I have a question.

Where does it go? I haven't checked the gm manual yet, but I'd figure I'd be lazy and ask you guys. Simple dumb question, huh?

Thanks
Chris

If you thought your question was dumb, how bout this one?; What are you talking about??? Upgraded ESC??? I never heard anyone talk about this. I know ESC is electronic spark control, but what is there to upgrade? I have an 85 if that helps answer my question.

Thanks for the help, guys. I don't know what's up with the forum lately, but it didn't display the first 3 posts after mine for some reason.

The upgrade ESC is GM PN 16038331. It cross-references to several different parts, depending one what auto parts place you go to. Autozone showed it as a Borg Warner part ESC108, Napa showed ESC209.

I simply disconnected my knock senser. No false counts, here. As a matter of fact, no counts at ALL. Good luck, and...

RACE ON!!!

So your saying this newer version is a direct plug in, but offers better performance via better control of knock counts?

SBNova, that's the deal.

While at the 35th Anniversary tent at Carlisle 2001 Gordon Killebrew stopped in to answer some C4 questions and I asked about false knock I was getting. He then gave me that GM part number for the upgraded ESC; though I don't know what application it came from it certainly cured the false knock issues.

65Z01,
When I ran the part number in GMpartsdirect.com, it came up as for a 4.3L, but it didn't say which application. I don't know if that's right or not, because when I had an auto parts place that wouldn't cross reference try to pull it up, we had a really hard time. The only gm vehicles with a 4.3L was the S10's, blazers and full size pickups, I thought.

:cheers: The NAPA ESC 209 is an Echlin part...Borgwarner makes great gears and stuff, Echlin makes great electronic stuff IMHO :D
