ECMlink 90-91 vs. 92-94 DSM Link

[bgold87]

I bought an ECU with linkv3 already but is there a way to tell if it’s a 90-91 version or 92+?

There is i only 1g no year specific.

Only difference is the 90 ecu vs 91-94 ecu but uses the same exact ecmlink chip.

This is what I got. Near as I can read, the 3 verticals boards in center mean it’s a 90 and to put in my 92 Id need to swap PINs. Can anyone confirm?

You would need to do a little more than that. Honestly, I’d just get a 91-94 ecu and swap the chip over.

90 is different from 91+.

It should have a MD# on it that would identify the computers origin. Does it have one?

 

[streetraceboi]

Check the MD number on the case. Here is the ECU list. Based on my quick research, the E2T34478 ecu is MD145903, which would be a 90 ecu. Double check though

I just swapped wires on my 1990 when I put a 91 ECU with link in it. Same applies to you only you are using a 90 in a 91+, they swap the same wires.

 

[ATEAV8]

Swapping the wires doesn’t make the tach functional. If you don’t care about the tach, continue on

 

[1990TSIAWDTALON]

True. I had to rewire my ptu/coils when I went with a ARCII box, but the swap worked out and all things function as they should, thank goodness.

Thanks all. Near as I can tell all I have to do to use the 90 in my 92 is swap wires. It looks like if you’re putting a 91+ in a 90 then u have to do more to deal with the tach issue.
