Hello Guys!

I´m new here at ecuedit.com and already reading and searching for much information for my project car.
I´m working on an VW Mk3 Syncro which i first engine swapped from the 1.9tdi 1z with wastegate turbo,
to the 1.9tdi AFN with vtg turbo.

Now as i built an selmade exhaust manifold for running an 3.0tdi turbo which was changed from elctronical to negative preasure, an frontmount intercooler bigger nozzles and a bigger pumphead 11mm different camshaft new head gasket and so and so on..
I wan´t to make an adapter for running the EDC15 instead of the MSA15 becuase it can be tuned via OBD.

I have both wiring diagrams, one of my car and one of the car where the MSA15 came out, an MK4 with ALH Engine. (Please tell me if I´m allowed to post these here)
But my skills in reading wiring diagrams is not that good and so i wnated to ask maybe someone here have already done something like this or can help me here, as i would really like to tune the car by myself and get it running properly.

When the wiring is done, the engine will be placed in an MK2-Syncro and before bolting it in, i will put in new rods, new bearings, new piston rings, maybe i will also port the head of the engine.

Thank you and best regards from Austria!

I'm searching for MSA15 tuning files but came across your post, it is possible to make an adapter from 68 to 121pin,I have a pinout diagram somewhere which I will post it up below.

My VW T3 now as a TDi with a 68 pin ECU, but I made a complete loom to take the 121 (EDC15) ECU and CANBUS cluster, I used this diagram so I know it's at least partially correct.
