part #s for ECUs?

[t2000gts]

what are all the #s for ECUs in the 2000+ manual AND auto?

and for the new matrix XRS manual and auto?

where can i get this info if nobody has it already.

Celica GTS info:

2000 ECM
89666-20082 (Manual)
89666-20092 (Auto)

2001 ECM
89666-20083 (Manual)
89666-20093 (Auto)

2002 ECM
89666-20190 (Manual)
89666-20200 (Auto)

Knock Sensor (2000-2001)
89615-12090

These numberes are off the parts catalog, I THINK there may have been an update to the number for the 2000 ECM because of a TSB on misfire so if your doing the ECM swap probably best to use the 2001 part numbers. There is a second 2001 part number that has the 7800 RPM fuel cut but I didn't bother to list it.

I dunno the numbers on the Matrix stuff but the Matrix ECM is COMPLETELY incompatible with the Celica so don't worry about it too much.

the old 2000 ECM ends in 80 and 90 respectively... 82 and 92 are the updated ones i believe.

[Raymund]

funny, I have two ECUs with 20081 m/t #. manufactured date stamp on the bottom of the ecu is 8/26/99 and 9/1/99 for the other.

[Griffin]

did some digging. 20081 was original - it superceded to 20082 in Aug. 2000, and 20083 is the one in the TSB. Supposedly there was never a 20080.

relly weird.. my alldata part numbers are showing 80 and 90... and when i put it into trademotion's part locator it gives me the right part: 2000 celica GTS ECM.

which ones had the 6k vvtl-i engagment point vs. the 6.2k point? Or was this due to something other than the ECU?

[Griffin]

Hmm I found the 20080, it doesn't sub to any new numbers and according to the info was only in production from 8/99 to 9/99. Its not in the EPC and you can't even enter it to order it. Very weird.

i'm pretty sure the matrix auto has a 8300 or at least 8200rpm rev limiter (indicated redline)...i was wondering if i could somehow pull a frankenstein, and take that part of the circuitry (is it stored in a chip? a circuit?) of the ECU and transplant it into my GTS Auto ECU (7800rpm limiter).

you think it's possible?

do i have to wait until i get my degree in computer engineering or can i have someone do this? :)

[GTS LAID]

naaah.. it'll take a lot more than that to do it.

the Matrix XRS (2zz-ge version) comes in auto? I thought you could only get a six-speed with it? I gotta go and see.

Yup - you can get it auto or manual

I believe there were at least three ECU's in 2000. My car was manufactured Feb. 2000 (20082 ECU) and defniitely has the 6200 rpm cam switch. I think only the 20081's and possibly the 20080's had the 6000 cam switch.

[GTS LAID]

well mine was 7/2000 and had the 6000 switch

[igotan02=/]

there are ecu's with diffrent cam switches? and is there anyway u can tell which ecu has the cam switch of 6k?

[autxr]

Good thread. Where is the part number located on the ECU? Just pull off the plastic cover?

Mine is a very early car (purchased in 10/99) and will probably have the earliest ECU (8300 rev limit and 6000 rpm cam switch).

Edit: Car purchased 10/99 NOT 10/00

[Griffin]

Its on a big sticker on the large front panel. Basically VERY hard to see without pulling the ECM up out of its little plastic home.

Are you sure of this? The only way to tell is on a dyno. According to my tach the switch occurs at 6000 but the dyno tells otherwise. My rev limit kicks in early on the tach as well, even though the dyno shows it revving to 8300. I think Toyota offset the tach needles or something.

[GTS LAID]

heres the funny thing... well we have confirmed anywhere from 5800 to 6200 engagements... i just dont know which one i'm in...

i am very close to doing a 6 speed swap to my auto gts. But before i pull the auto trans out i'm gonna plug in the computer that came with the 6 speed setup. I'm hoping it will still actually shift and drive normally, and besides that I'm hoping to see a higher redline and earlier engagement. Right now it doesnt feel like "lift" until around 6700 and then it redlines at 7700. I'd love to see another run at the drag with the wider "lift" curve. My previous run was 16.8 with only a home made cai mod.

[GTS LAID]

you mean the manual ECU in the auto..... i really dont see how it could work.... the ECU monitors what gear you're in ... the speed, RPM and a billion other parameters that dont match between 6 speed and auto

It won't work. This is not a guess or conjecture. The ECM is not programmed to control your trans which is shifted electronically... your car will probably not even move and if it does it will run like ****. Sorry.

Oh well that blows that idea. It was gonna be an experiment done in the process of completing a different goal. It would be good news if it did work, thats too bad. I think they limited the autos to 7700 to help the trans last longer...Mine shifts ok but not firm enough to really handle high rpm shifts. Those clutches may burn up if i was able to hold 8300 and then shift.

[t2000gts]

griffin/gtslaid are right about the manual ecu in auto thing

ALSO...i think the difference between 7800rpm and 8300rpm has nothing at all to do with the transmission. if you can spray nitrous and last fine, or bounce off a rev limiter, it can handle extra rpm. i think it's at 7800rpm just because that is indicated redline and that is a normal automotive manufacturer practice. the 6-speed SHOULD have been 7800 but they know that it's impossible to keep it on the 1-2 shift (for most drivers) that way and they copied honda's lead and made it 8000+
