Just an ECU update, and already 70 hp more..... for $1200, I'd take that for sure. They don't change a single thing on the engine, just update the computer a bit. That 400 hp version sounds quite interesting too.

This is great. I think it was always given that BMW had the 335 tuned well below its actual potential, so it will be interesting to see how far this engine can be pushed within reason.
So - now the ovbious questions.
1: This will void the warrenty, right?
2: Could I "hide" this upgrade when the car is brought in for service?
3: What real consequences will this have on engine wear and tear? Could we expect a modified 335 that's driven in a reasonable manner to suffer significant premature aging because of an ECU mod?
A shame this car doesn't have an LSD. Straightline acceleration ought be just fine though.

Anytime someone messes with the ECU there is a chance of things going wrong. A friend of a friend had his S4 modified and then had it chipped...came home parked his car woke up in the middle of the night with his alarm going crazy and his windows going up and down like the car was possesed. The next day he tried to take the car to the dealership but the thing started stuttering on the highway and it finally gave out. He had the car towed and dealership said that it was the ECU that was screwing everything up. Plus, I've heard ECU horror stories from others as well. I'm not saying that ECU upgrade is bad, when done right its great but it carries with it a big risk and also revoked warranty
