TCS removal

Awhile back someone was nice enough to PM me the procedure to remove the TCS from a 92 9000. Since the fire I really haven't had time to think about playing with any cars. Low and behold I finally got the car home and the PM is gone. In short could the kind soul who sent it to me in the first place resend it?

Thanks,
Marty

i guess i was that kind sole...

procedure used to be up here as a sticky, but i dont know what happined.

-youll need to change the throttle pedal,
-adapt the TCS throttle cable, or add a non TCS cable,
--------HELPFULL HINT----------, when pulling out the a new cable from the local boneyard, pull the cable from the actual cable itself, not from the outer housing, once the cable has been disconnect from all sources, it simply pulls out of the firewall, however pulling from the housing will brake the housing every single time, when pulling from the inner cable, the Barb on the other end more pushs the housing though, and does not brake anything

-transplant wireing harness from bulkhead forward,
-add non TCS TB
-change coolent temp sencer to non TCS sencer

-add pins in both in the jetronic ECU plug, and in the circular plug that goes though the bulkhead, pins can be removed from old TCS wireing harness, there tricky to remove at first, but once you get the hang of it, your golden

however, you can have a running driveing car with nothing more than a TB change to a non TCS style.

however it wont run well, it will be like not having you AIC and TPS plugged in,

-also the 1992 jetronic computer isnt set up to take either the AIC or TPS, so a 1991 ecu is helpfull, the car will run with the 1992 ECU, but again, just not as well.

- the DI/APC computer is the same part number, so im asuming that it doesnt care.

included is a link to the wireing diagram i used to set up the TPS, as far as the AIC valve goes, ive had the best luck running a c900 8v aux air valve (much more reliable than an AIC)

after all this you can remove the ETS computer, all the extra check valves, re fit car with proper vac line routeing, and life is good.

extra credit:::: i also ground pin 13 from the ETS ECU plug, the ETS system diagrams i have says this is grounded when no faults apear. and apon grounding you can hear a relay click. im not certain exactly what this does, but it just seams like a good idea.




wireing diagram

Semi-hijack, but isn't TCS removal far easier on a '93? I'm seriously considering buying a '93 Aero.

To the best of my knowledge, virtually impossible on a '93.

That is unless you are willing to revert the car to LH with DI/APC, or switch everything out to run 1994+ Trionic 5.

Otherwise, good luck finding a non-TCS 1993 Trionic ECU. To the best of my knowledge those never made it to the US, if they were made at all.

nothing is impossible,, just a royal pain in the @ss ive heard of someone doing it by using a later non TCS aero, and quite literally swaping the entire harness from tip to toe. compared to a 1992 where its just from the bulkhead forward.

ive heard of several 93aeros w/ tcs that have just had an off switch wired in. i have a printout of how to do it, you just have to turn the switch on every time you start the car.. doing it on my own aero when i find the time.

The off switch will only take TCS out of the equasion.

The real issue is the electronic throttle system (ETS) itself. The limp home mode and various failures are cause by faults in the electronic throttle system, not in the traction control leg of the system.

So the switch =/= solution to the problem.

look under the hood at the throttle body,, if it has a black plastic cover on it, its a TCS throttle body

also, the wrightup listed above was for a car with a very different EFI system than your 94 has.

Also, with the advent of T5suite we are able to make our own non TCS ecu's,, this could make the process of converting a 1993 much more attainable

How the hell do you get the throttle cable out? Obviously the whole thing has to come out- "welded to the firewall rubber grommet" and all, right? Sometimes I get so pissed off at myself for getting bogged down in what surely will be a simple procedure.

I personally use wheel cleaner, tire dressing, a sponge, and some elbow grease.
