General Swapped ECU, non-EPROM, not turbo?

[GSLENK]

I've owned my laser awd/turbo for about a month now. I have caught up on maintenence and the first thing i want to do performance wise is get DSMLink going... Well while doing my radio etc... I dug a bit further to see what ECU I actually do have.

The closer I got to the ecu, the more appearant it became that the previous guy may have swapped parts into his project car, from this one.

My ECU is MD159963 , E2T35676 , no EPROM "chip" for socketing. It has 3 plugs to go in, But on the inside, there is 6574M, and JE331B997A.

After checking here, Eclipse Talon Laser Galant 3000GT Stealth ECU ID Reference
I am utterly confused.

My car: 1992 Plymouth Laser RS/t AWD (manufactured January 1992, so it is a 6/4)

My ECU case: MD159963, E2T35676, points to 90-92 3S 3.0L DOHC NA FWD MT and AT (wtf?)
My ECU: 6574M , points to 1G DSM Turbo FWD 90-92 MD166260.

So I don't really care about the case not matching, but i did find it odd, any reason for this?

I suppose the actual board a FWD in a AWD, doesn't really matter as far as proper stock tuning?

Does this mean I can still run DSMLink? I know they do a conversion, would this qualify as a core?

Should I buy/find a 90-92 AWD ECU?

Thanks

Maybe im wrong but you need a awd for a awd car, fwd can be used in awd if im not mistaken if you have a awd get a awd ecu. Fwd into a awd, awd not in a fwd.

AWD or FWD doesn't matter. The only thing that matters is the following:

Turbo or non turbo
Auto or 5 speed
90 or 91 - 94
Federal or California (emissions)

GSLENK: Tom or Dave (ECMTuning aka DSMLink) can use your ECU to do the conversion for v3. No need to find another core. Keep in mind the conversion board will only work for Link v3 though.

Awsome. thanks. do you guys know by any chance if he has cores? It seems like he might. Im awaiting his reply, unless someone has recently been turned down... (the main point being that socketing my board will be 135, and the new board, socketed, 265) thats only ~130 to keep my car on the street while the work is done.

Also how does this work? theres a socket in the board that is pretty hard to reach... The only pictures I saw were of obd2 type link cables. Does the cable stay plugged in all the time? I assume I will have to cut a hole in the emu housing correct?

Gonna have to email him.

Honestly, if you really need your car that bad, your best bet is to just go to a junk yard (or our classifieds section) and purchase either a 91 to 94 eprom ECU and have it sent out to be socketed, or a non eprom ecu (also 91 to 94 turbo) and send it to get converted. Or (if your lucky) purchase the whole setup from someone (DSMLink, and ecu). You'll need to email them to see if they currently have any ECU's in stock. Turn around with ECMTuning is very quick (few days max), so if you can just send your ECU, that would be the cheapest. The cable technically only needs to be plugged into your car when you are making changes to the tune. Other wise it can be kept in a safe, dry, cool place.

I think ill go the route of finding an Eprom ECU and maybe DSM link locally if im lucky... Wasnt even thinking of it...

So what I am looking for is a 90-92 (my car born jan. of 92) AWD. according to ECU ID at the posted link i want: MD166262

And its a crapshoot as to whether it is eprom or not right? Ill just have to open it and see.

Any other years or options that will work 100% with my car? maybe a FWD? maybe a 92-94?

If i get it cheap enough, I might try the socketing my self, Im pretty good with a soldering iron, and have played with some simple computer boards...

ANY 91-94 turbo ECU will work in your car. Just make sure it's for the same drivetrain as your car, i.e. 5spd or Auto. FWD/AWD doesn't matter.

Great, thanks. I think i found one locally then. 93 5sp, awd. sounds like it should work in a 92 5sp awd.

 

[92AWDHX40]

Yes it will work in it 91 94 no problems 90 91 -94 wiring needs to be switched around.

So I lined up this deal... this guy has a secketed eprom ecu from back when Todd at TMO did them... And i have a few questions:

1 Is that work relaible?
2 Will it be compatible with DSM Link? (I assume so since it is just a socket...)
3 I assume there is a non factory tune on that ecu, all i need to do is hook up the dsm link and reset it to factory? (i wont be able to copy the factory tune from my non-eprom ecu.

Thanks for the help

When you get link youll have to read the demo, if you install it, if not use the ecu you get, im not sure, what factory tune. Its just stock. Have you read the ecmlink page?

 

[e85_4g63]

Your best bet is to send your ECU directly to ECMTuning, and have them check it over before using it... (seriously).

I tried but then i got really interested in speed density... theres so much cool stuff on there. I guess ill try combing through again. they are "located" about a hour from me, so i will try to see if i can stop by to avoid shipping turn around times. Will definately take the ecu to get it checked out.

Its a reasonable safe bet that the ecu, although socketed and tuned by todd of TMO, will accept tunes by DSM link, and be compatible? assuming the ECU itself is good (i think it will be)

Todd didn't really do much in the way of tuning. He just modified code to make things easier for racing and to go faster. he added the NLTS, increased rev limiter, removed fuel cut. None of those have anything to do with tuning.

Great. well the local one I "found" Sold before i could get my hands on it... I guess it back to the search for me. At least now im well informed. Thanks

Just buy a ecu from ecm already ready to go done. S d is cool takes a bit to learn, not yet for me but one day.
