Hello everyone

seeking guidance from an expert

I just replaced the intake manifold in my 2c3200 and am now attempting to repair the swirl flap.

I would like not to deal with the issue of recalibrating as I do not own ista.

Reading this, I was considering the possibility that I may either

1. fasten my own actuator without resetting it by removing flaps while keeping the bar in place

2. Acquire the bung that I now possess by removing the bar and flaps.

Would either of these choices not need an Ista reset? Also, what's your recommendation?

Getting good gas mileage isn't essential to me, therefore I've removed the flaps from all of my BMWs without a problem.

grateful for any feedback

It has to do with the motion, not the motor, therefore you'll have to make adjustments and reset it to learn the end stops regardless of which direction you travel.

so, the absence of flaps will cause the bar to revolve infinitely, even with your motor attached.

remove the flaps and bar, replace the manifold and then find a place to reset the modifications. ISTA isn't required; autel, launch, and others can accomplish the same.

Yeah, the only thing is that I personally just have BimmerCode, so I'll have to search around then. With the new intake's bar and flaps removed, I figured I could get away with it.

The flaps closing against intake constitute the stop point, hence the answer is no, regrettably.
