if someone can send me a link to ecu info I am trying to find out what year model etc used this ecu

mainly if its a match to a 83 2.5 engine

bosch
0 261 200 086
944.618.121.05
typ 944 mws-02

That should be the DME for a later 944 model, after 2/85. The early DME has a pretty thick case on it. The late DME is just sheetmetal.

Arominus

That would be an 88 944 dme, if you want to run it you would need the AFM from a late car as well IIRC.

I am trying to work out a problem I am having with the car losing power and going lean when the WOT tb switch is engaged. wideband goes 16. I am wondering if the swap the prevous owner did has the wrong mix and match in regards to engine to ecu to sensors etc.

the motor is a 83 for sure so you guys now say 88 ecu.
so I question if I have the right MAF/ DME CTS etc.

V2Rocket

as long as the DME/AFM are the right pairing (early/early or late/late) the car should run fine, assuming everything else is in order. an early motor does not care if it has a late dme as long as it has a late AFM as well, and vice versa.

understood i need to now find out what part number the maf should be to match the ecu in it

cool thats the one i have. now i need to find out what the cars problem is. maybe I will get a new cts to start

It sure sounds like the TPS is faulty. I was having WOT problems with lack of power, and I replace it and now it goes like it should.l
