What I want to know is how hard or what problems would I run into putting S4 TII running gear into a S5 N/A? I plan to go Microtech this winter neways so the S5 ECU wont be a problem.

The motor will bolt right in, as well as all of the other stuff. You should give more details about your setup. [/quote]

Well the car has a bunch of stuff done to it but the main thing im worried about was the Dash harness in the S5. The micro tech will take care of the engine harness problem of a s4 motor in a S5. Do the plugs (or plug, cant rember if there are 1 or 2) from under the dash plug into the microtech? Because if teh micro tech unit goes in place of the stock ECU id think they would have too.

Lol sorry about the convertible crack! they just arnt as appealing to me as the hard tops https://www.nopistons.com/forums/pub...IR#>/blush.png [/quote]

The engine wiring harness also does the wipers and cruise control. You'll need the yellow wire with the white stripe for your stock water temperature gauge. The Microtech isn't a "plug-and-play" ECU. You have to hardwire it into your car, unless somebody is selling a plug-in harness.
