Active Autowerks ECU 128i

From my respective, taking out and shipping the ECU, is too much of a risk to gain 15hp.
In the future, whenever dealer will flash it you have to start all over.
Chip would be way more practical

Any updates guys?

And am I new to the idea of flashing and ecu tuning so correct me if I am wrong.
A flash is when they just "rewrite coding" within the car's ecu to achieve the different throttle maps and air/fuel ratios and such?

Secondly, the picture shows an AA ECU module, so is this just a flash or a full ecu replacement? I'd think if it were a full ecu replacement, you could just pop your old ecu back in there for when you go to the dealer.

I am not sure if any 1 series owners have done it, but if you look at the 3 series forum people say it is the best tune out there. Better then the OE tune, and better the powerbox. It is a software encoding, no module, so you need to take your car to a nearby AA tune shop(they have a lot check their website), or ship them your ECU. I haven't heard/read one bad report of it yet
