How to Identify an EPROM ECU [Merged 5-9]

[olmytsi]

You need an eprom only if you want to get a chip or dsmlink.

thanks you so much... thats waht i was looking for!

How can I tell if i have an eprom ecu or not?

Check this out hope it helps.

The Ecu will have an ( E) written in the bottom right corner!

I am looking to get a eprom ecu so I can do the DSMLINK. Do all 95 turbo motors come with the eprom ecu? If I was looking at the ecu, it has numbers on it. With out opening it up, how do I tell? The person I am getting it from sent me some pics of the ecu, They said they did not want to open it up. They state it came out of a 95 gst. I just want to make sure before I spend 125.00 on it.

It's better to open it up and check because sometimes non-eprom ecus end up inside eprom ecu cases.

He probably doesnt want to open it up because he knows its not an eprom. Why doesnt he want to open it up? Its 4 tiny screws and the top just comes off. My 3 year old daughter can loosen 4 screws without damaging it. My advice is to save your money because it isnt an eprom.

 

[99redgst]

Not to mention 125 for an eprom ecu would be a hell of a deal. They normally go for around the 200 range. If it sounds too good to be true, it probably is.

 

[daren_p]

Ask him what all the letters & numbers are on this sticker. But like others have said you can easily swap cases so even if its the proper ecu part# on the case it could have a reg board inside. If he doesn't want to open it, Id pass on it. You will not damage it, its only 4 screws like was said. If he can't do this its probably a scram as $125 is very cheep for one of these, there's probably a reason for this.

 

[DJ23GSX]

Save your money. If he don't want to open up the ecu and send you pics then obviously he know's its not an eprom. If he knows what an eprom ecu is then you can bet your ass he probly checked it. Price too low pics are horrible i say run away as fast as you can.

 

[95 tsi awd]

how do you if you have a eprom ecu? because im looking in to buying a 95 gst totally stock. how would I tell if it has eprom

Do not just check the cover, take it completely off and check the bottom right corner for the Eprom chip. Having the "E" does not 100% guarantee you have an eprom.

 

[805DSM]

yeah you should check for the "E" and open up the ecu...just be carefull when you do that

 

[sureshot971]

I thought only the first half of the 95's had them?

 

[spyderturbo007]

All 95's did....But, what if someone switched it. Open it up and look for the chip.

Not true. Most 95's came with an EPROM, not all of them.

 

[90laserRSfwd]

I just bought an eprom ecu for my 90 laser rs turbo and it has an "E932a" eprom chip. Does anyone know what that is coded for (my car is a fwd 5 speed) and I think the eprom is for an auto trans. anyone know 100%? help me I'm not eprom smart. thanks in advance

It looks to be from a 91-92 Federal Turbo Automatic AWD car. Since its out of a 91+ car, putting it into your 90 won't be plug and play exactly. You'll have to switch pins 6 and 14 on the ECU harness and do something about the tach. Check out this page:http://www.dsmchips.com/1990ecu.html for info about that.

 

[awdmonster1904]

how can i tell if my ECU is eprom??? can some one show me ?maybe a pic or something

thanks

Here is a good thread to go through, but in the future I would recommend you do a little searching.

This is about the n(th) post I've made within the past few days that I've gotten an answer straight from VFAQ/1000 Already Answered Questions.... I love it, that site makes me feel so smart!

>>>How can I tell if my ECU has an EPROM?
You would already know this (hint, hint) if you had used the FAQ Locator. Read Todd Day's EPROM check webpage.

One fact that is not mentioned on this page is how to quickly check ECUs *after 1990* for an EPROM. There is a label on the top of the ECU (not the sides). If this label has an "E" in the lower right-hand corner, you have an EPROM. If it has an "M" or "T" in that corner, you do not have an EPROM. 1990 owners have to open the ECU to find out, as there are both EPROM and non-EPROM 1990 ECUs. This tip is also on this page from the developers of the DSMlink (good link).

Galant VR-4 owners, again, have an edge - owing to the low production volume of that model, GVR4s are almost guaranteed to have an EPROM.

The Last Word: Hey, not ALL 1990s have EPROMs. Can't you read?

But yes, as 1GawdJunkie's link states, it's best to open it up and take a look.

Is this part number a 95 eprom ecu that I can socket?

md321911

e2t61676

5712


Thanks

Actually that's a 1996 model year ECU not 1995 and not an EPROM.
Your looking for a MD312464 or MD309947.
