With the M113 I was thinking of a Link ECU with the stock loom as I want to get rid of the Mercedes electronics, too limp mode prone for a race car. What ECU do you make, is it stand alone and does it connect into the stock engine harness? If I went the M113 way would it's trans be better assuming that it was in good nick?

I agree with Neil's summary of the combinations. I can modify OEM ECU's to operate the M113 or M113K with auto or manual, and connect to the stock wiring harness. An aftermarket ECU will not run the engine (and integrate with the car) as well as the OEM unit can and you could still keep all the factory safety stuff (eg. ABS and Stability Control). If you went with an M113, I would just modify the car's original ECU. I can get rid of anything that would generate limp codes or limit the torque, or rpm. Where are you located?
