91' R/T Trimcal in 92' IROC R/T

[turbo_III]

tach works right off the bat, no changes needed from what I gather

[navyboy65]

Hey I am planning on trying this mod on my 92 Spirit In hopes of running a 91 Trim Cal.
As to the tach and cruise control has there been any more info on this? Or if I do the afor mentioned wire swaps and running the 2 wires to the clock spring wiring, I should be ok???

I know it's not a must but I want to see if I can make an adapter instead of modding my SBEC connector, Junk 60pin SBEC and connector

You do not need the connector. Just drill out the blank spots on the back side of your 60 pin connector (wiring harness side). There are little divets there to guide the drill. Much easier than you think.

Ok Now that I just got my 91 trim cal in, I want to do the install in the morning. Just wanted to double check that the above quote is the right info to make the 91 trim cal work in my 92 Spirit R/T!
Thanks, Seth

Well I looked at diagrams from '91 and '92 and that's what I discovered...Jackson a.ka. lotsashelbys has tested this before and he drove it around the block and it worked!

I made this work on a 92 R/T in a pinch once, too. Seemed like I had issues with cruise control, IIRC.

Hey thanks for the double check. I am running behind on my up grade as I have to install the *+40's, *fwdp fuel rail, *acufab AFPR, *3bar map, 255l fuel pump, SBEC wire mods(1992 to 91)and then the trim cal set up! I've done the things with the *'s so mainly just the wiring mods, 255l fuel pump and actual trim cal install is what I have left! THen I get to play with it and fine tune.

I've read that too about the cruise control. I though though if you made jumpers from the wires at the clock spring to the sbec connector it works

Pin 48 goes to the WHT/RED wire on the Clock Spring

Pin 49 goes to the Pin that doesn't currently have a wire(this is if the clock springs are the same in the ''92/93's as the 91's

For some reason my cruise control doesn't work right now with the 92 computer and all 92 wiring??? We'll see if after the swap to 91 that is fixed?
I'll keep wrking on it on my weekends and hopefully I'll get it done soon!

Pretty sure it will not work, unless you get the clockspring and cruise switches from an 89-91 AA body. 89-91 used discrete switches, 92+ all use two wire resistive switches.

I'll be looking into this more. Trying to research part #'s, but I am away from my catalogs till thursday night! I'll post what I find # wise and when I eventually do the physical research!

Sounds good!

Ok, I just did a quick look up in my parts catalogs and searched them online.
For 1991 The speed control bar/switches should be 4565042, online nothing came up. Weird, no super, probably NS1'ed?
Clock Spring 5252468, online shows 1990-1992
For 1992
Speed Control Bar/Switches 4565265, online looks to cover 1990-1995
Clock Spring 4637952 super to 4688552, online looks to be 1992-95

Don't know what it all means? But it does seem that they maybe inter-changeable????

It's quite possible, I'd have to look into it which I will eventually once I start working on my next project. (gonna be a while yet) But when You're racing who needs cruise anyway

Ahh great! I was out doing my Walbro 255L fuel pump up grade and the stud like thing that goes to the the drivers side fuel tank strap sheared off, and is pretty much flush with the body? SO that is something I have to fix now! Anyone have a link to a thread on how to fix this? I'll be searching it up and looking at replace ment parts right after I post this. Good news is that All that is left is to now fix this fuel tank strp stud and to install the trim cal & wire mods and its test time!!!!

Fixed the broken stud, by drilling it out and using a bolt from inside the car (under the rear seat & trunk area). Read it on this thread fuel tank straps!!

Still have to install the trimcal and wire mods, but I am getting close!!!!

Update. Well I got it just about all togeather. Well that is I have it all hooked up except for the Cruise controll wires! I got it to fire up! It stumbled at first and stalled out but then it was able to smooth out and hold an idle. My fuel install only had one leak , and that was a plug that FWDP installed in the fuel rail that they did not seal? I did a bit of reading last night as to what my AFPR should be set to, and most say stock 55psi, but other say something lower about 10-20 psi lower, while all agreed that you have to tune to your car. But to do this you really need a wideband O2 set up, which I don't.
WHen I first started the car with out messing with the AFPR, (about 25 psi) the car had great throttle response, after I turned it up to 45(yes with the vac hose off) it seemed like it got worse?? Any ways I am about to head out and play with it some more! I'll update whit what happens!

Ok I turned the AFPR up to 55psi and seems to run great. But as soon as I left the drive way, the check engine light came on??? I got 5 codes 2 of which are the *standard ones; *12, 41, 53,34, & *55
41 should be Altrnator, I did have the charger hooked up with it running so that might have caused it, but the trim cal was reading the alt out put @ 13.5 volts while the car was running, and from memory it should be more like 14-14.4v. This code should also be the only one to cause the light to come on!
53 is internal SBEC fault, don't know if thats is supposed to be there with the trim cal reprogram or there is a problem???
34 speed control short or open, I did hook up all the speed control wires but maybe I did it wrong or I need to get some 91 switches (which I have a want ad up for some!WTB Cruise Control/Elec Speed Control Swtich(es) 4565042)

I drove the car for about 7 miles even with the codes and it seemed to do fine, didn't really get to open it up though, because to many looky lews out because of the 4th! So next weekend I'll resent the codes and see if I can get the chance to open it up!

Happy 4th all!!!

53 is normal. 41 is the reason for the CEL.
