wonder if the drive by wire and VVT built into this ECU would cause problems... guessing one would have to pretty much re-engineer this ecu and base it on the AAN specs coding out the "Fluff". Iam very good with the hardware end of things, so adapting sensors and such is totally doable, but roadblock would be the software end :S
what about the Rip Chip from 034 ?? The chip is not made by 034.... it is made by Miller Performance in Canada for BMWs .... some what the same ECU like yours . I have been running the Rip Chip for 3 year now and the chip will allow you to change the timing , fuel , injector timing and some other small stuff . I am pushing 480hp with the stock ECU with the rip chip inside ...( with a lot more bolted on to the engine ).
034 sux when it comes to customer service but the Rip chip is perfect when you dont want to go standalone ECU. check out Miler performance website . Their chip is called the WAR chip
https://www.millerperformancecars.com/store/war-chip and their forum is good for suport and software updates. The UI they use is a Java base and you can rewrite it with NetBeans if you have time on your hands
It will take you about an hour to install the Rip chip and then about 2 hours to fine tune the engine pefect. I have alot of base files that are better than 034 has for the Rip chip if you buy it ... PM me if you have more questions
