RSXDC5, I advise you wait until I confirm it works before ordering. Thus far, I have a bad feeling it won't. I'm not new to modifying (I know my way around a wankel 13b
) but this is my first go at BMW...
The N20 motor (and other BMW turbo motors) all seem to have vacuum activated wastegates. In the BMS tune, you intercept the boost solenoid, which seems to effect wastegate activation. However, on the N26, the wastegate is electronically controlled, and there is no boost solenoid (that I can see). I've got a lot to learn about this motor but at the moment, because wastegate activation is electronically controlled rather than vacuum, the BMS tune doesn't seem to be compatible. I could be entirely wrong though (and truthfully, hope I am wrong)!
I will be
very disappointed if this tune is not compatible. Not disappointed with BMS (seems like a great product!) and not disappointed with BMW (great platform!) but disappointed with the situation. Why N26, why?!
Anyways, emailed BMS, let's see what happens. Fingers crossed I'm a massive noob
