We offer a free 3 time reflash on the kit so if your dealer resets the ECU and gets rid of the software, we will perform the reflash for you 3 times for free. You just cover shipping the ECU to us and shipping it back. It is 328xi compatible, we can do ANY of the engines
how much is the cost after the 3 times of free updates? also can you guys make a custom map for my friend as he has full eisenhaus meisterchief exhaust.
it takes 3 days to upload the map on the ecu? there is no tampering with the ecu itself right like going in and soldering some stuff, etc and is untraceable by dealer when returned back to stock?
more importantly speed limiter gone and whats new rev limit?
thanks and i think that sums up all my questions.
