Hi!

If I want to run the engine with the better FSI coil-on-plugs, do I need to change something in the ECU software?

The dwell times ideally.

If I understands it correctly, I can just change to the tfsi coils right away without any hardware modifications besides the mounting spacers?

All that because I have the AWT engine that already have the right connectors and all that, right?

You can yes, but they can be run with less of a dwell time, which means they aren't saturated for as long..

Loads of people just bang them in, but why would an ECU running these have different times to that of one that doesn't?

Change them if you want, I have.  There's an excel file that helps choo..

Yes what is the part number for the 2.0 coils?

My friend just did the 3.0L Coil Swap and ICM Delete on his S4 so some wiring mods where required if you don't want to purchase fancy cable/harness.

Now the coils he got where $20 each at Napa Auto Parts which I have verified they have them. Now Is there dwell time differences with the 3.0L coils?

If so what should it be?
