Might have a problem with one of my boxes.
'88S.

Other than chips, can I use any 87+ DME or KLR?

rberry951

Yes, just swap the chips.

You can also use older boxes if you convert 24 pin to 28. It's easy task to do

I have an 89 T DME and a 87 T DME, and they are both fine in my 89 T as long as the right chips are installed.

86-87 are 24 pin while 88-89 are 28 pin chips.

does anybody know if you can use the turbo S dme on a 86 turbo?


TIA

You can use turbo S DME on a 86 turbo if you have in that DME box a '88 non S chip. All boxes can be used on all models if you use right chip. Early boxes can easily be modified to have a 28 pin chip

I've taken an 89 T box, with an 89 T chip, and put it in a 87 T and it drove fine. I'd suspect the fuel maps might be a tad off (due to turbo size?) but it worked fine for us.

Good Question. I know the 86 DME will work in an 89 as the last Dyno run I did I swapped the DME out to see what the chips in it were doing. Ran fine if a bit rich (autothority and all) I do not see why an 89 DME would not work in an 86?

are the US spec 944 and 924S chips the same or are they different?
cause different people have told me different things

It does work, I have an '86 with '89 DME and K26-8

Olli Snellman

Nothing?

Nada, just 3 years newer!

Thanks guy - although even better - it was some random wiring issue to the MAF.
