Kind of "on topic" since this is for a TBI SBC into a Fiero

Do any of the ECM guys know if the 93 Caprice (ECM 16136965) uses the GM passkey system?

My diagram is pretty small and hard to read but I don't see it but I wanted to check to make sure.

Thanks

My experince with the Caprice's, from 91-93 models, is no, they do not have PassKey system...

(I worked as a mechanic for a security co. - lots of old cop cars ( 91-93 caprices))

Probably doesnt help much, but my 1992 does not use the passkey.

GM started implementing PASS-Key into cars as early as 1986 with the Corvette, for what it's worth.

After looking around for a while, I didn't see any Caprice from '91-'96 having the PASS-Key system installed. So - I'm going to have to say, tentatively, no. No Pass-key system involved.

Thanks Everyone,

My 1988 Firebird Actually does not have the pass key but I know that my 1989 and 1991 Trans-Am and Z28's did.

I didn't think the Caprice did but I wanted to check. I would imagine that there would be some reference to it in the ECM diagram but I may be wrong.

The info from TunerCats shows that the ECM supports VATS, but it does not mean that it was used in all applications. I know the TBI F-Bodies used the VATS, but the TBI trucks did not. My '94 Caprice has it, but it is a different engine system (LT1 style).
I don't have an editor for the 16136965 ecm, but it is pretty cheap. If needed, I could pick up the editor and fix the VATS and set the flag for a manual transmission for about $30. Let me know and don't be in a hurry because I don't keep the chip burning stuff set up all the time because I don't have room for it to stay out all the time. PM me if you want to work something out.

Thanks for the info Cooter.

$30 is more than reasonable and I may have you do exactly that for me. I don't do that much of the custom stuff so I don't feel it's worth it for me to buy a ton of equipment to burn 1 or 2 custom chips etc. Easier to pay someone to do it . (who has experience).

I've run across the same info. It looks like the ECM will support the VATS but like the TBI truck, it doesn't have to have it. My 93 TBI 4x4 does not have VATS and either does my 88 Formula.

My other 91 and 92 F-body's did but since I don't have them any longer, I don't have a reference to check.

Within the next few weeks, I'll have the engine in the car and wiring done. I may have you at least set that flag for the manual trans for me. (can the power steering pressure sensor and TCC lock-up be "removed as well" ? ). I think we shared a few posts about this in another thread.

Right now, I just fired up the engine with a 650 Holley and manual fuel pump. With less than 4000 mile on the build, I'm sure I'll be fine but I just wanted to have it running outside the car to make sure I don't have any leaky gaskets etc. I also may have to "isolate" the knock sensor somehow if the gear drive causes an "issue" but that's not going to "rear it's ugly head" until everything is in the car. (if at all).

At first, I wanted to install the fuel injection and run it outside the car but the more I thought about it, I figured that once this engine is tested and ready to go, I may as well get it the heck in there. I'll swap the Intake, pull the fuel pump, install the Block off plate etc and then install it. Once it's in the car, I can finish off the wiring and install the TBI. with the car on the ground.

I have the 93 truck and 88 Formula here for "reference" and i have plenty of spare TBI's, Sensors, etc for testing and a nice supply of TBI related spare parts like coils, distributors etc.

I just wanted to make sure I don't have a "VATS Issue" and wonder why I cant get it started when the engine is in the car. I think I'm all set to go now. I'll touch base when I have everything in about the PROM.

Thanks Again,
Brian
