Hello I have a 1993 Toyota Celica JDM I my Ecu (Serial# 89661-2B200) is not working right now and I have been trying very hard to find a replacement for it but to no avail. Everywhere I look dont seem to have it. Is there anyway someone can help me to locate the part. If not would there be another ECU that I could replace it with

Looking through this instruction manual for the A'PEXi Rev/Speed meter, there is a diagram of the ECU. Have a look at the scanned picture, can you tell me if this is the wire to cut to derestrict my car, like we were discussing a few weeks ago. (See attached file: ecu1.JPG) Cheers Dave

i don't think thats the one, if you just cut it there would be no pulses to the ecu and the speedo probably won't work.

Yep that looks like the jap 3gse Connector... Now weres me peanuts

Al, no pulse means that the ECU wont be tipped of when your doing the magic 115, I think the Speedo uses a seperate send than the one the ECU uses...Go on D cut the bastard real good...

Right do I cut it or not. Mart are you sure thats the right one, I dont fancy soldering anymore wires together, but I do wanna get rid of the restrictor. Cheers guys Dave...

cut the fecker.

What if it doesnt cut the limiter, will there be any other side effects, spose I just solder it up again dont I. Cheers Dave.

CUT THE BASTARD...solders cheap

OK then, but if it blows my car or it refuses to start, there will be trouble, and il be sending the boyz round, I know where Al lives so he can take the beatin for ya. :o)) Dave PS. What speed should I see if it all goes to plan, it currently goes to about 200 kph then shuts down.

seperate sensors? or the split feed? how much were you quoted for recharging the a/c? does ?60 sound good for a fill up of c12 or r12 or whatever you call the original and still the best illegal chill out juice?

seperate feed i would imagine. 60 quid sounds good hey...Ps just took that alt out tonite, spend bout an hour before i discovered the bastard of a bolt hidden in behind it LOL ps Marius serius give us a price on the Nokia's incl. postage to UK.

I don't own a celica (so I prolly don't know :p) But most toyotas with digital clusters (note that analogue needles do not always mean analogue clusters) have a gearbox pickup that sends 20 pulses per revolution (of the pickup shaft) to the cluster for the speedo. The cluster then divides this signal by 4 to give 5 pulses per revolution that gets sent to the ECU. Once again on every toyota that I've seen it's sufficient to cut that wire. In some cases the ECU notices a lack of speed sensor signal (you wont be travelling at 3000 rpm for half an hour unless your moving.. will you) and lights up the check engine light giving you a "Speed sensor" error code. The most elegant way to do it is with a switch. Interrupt the speed signal when you actually wanna speed, otherwise feed it to the ECU. That keeps the ECU and you happy. Mos. (Part time wiring dude).

lol, we own celicas (apart from the odd renegade with an audi) and we definitely didn't know :)

201?

it's a bitch innit, did you check the brushes? they might be replaceable.

I know u were Jem, I was refering to my state of Muldleupiness from all these messages..feck it im gonna subscribe to the GT4 and 2000 Celica groups...

Decided last night not to cut any wires, the diagram in the A'PEXi instruction book had 3 plugs on the ECU, when I came to look at mine, all I could find was 2, am I looking at the right ECU. Dave..

ARGH! shut up about AC. You have caused mine to break in sympathy! No cold air at all just outside air! does anyone actually have working AC? (U dont count Jem) Mark

My Air con is working fine, just what you need on these warm humid days weve started getting. Oh Sorry :o) Dave
