Have you looked into using Euro S50 ITB's on an M42?

I'm assuming it would be a cost/availability issue to go this route but it could be easier.

Just wondering if you know anything about this set up?

Default name... I have heard and seen that on some threads.... They are very costly.... Imo motorcycle itbs are cost effective. The first set of itbs shipped to my door was around $120 i think... These $180... Those euro bmw ones when i was looking well above $400

well it took some time but a friend of mine was able to squeeze in some time for me at his shop to do this...

been a little busy with some other things so the next few steps may be a while... but not as long as this update was.

Any plans on adding an adjustable fuel pressure regulator and a WB O2 sensor to help tweak the fueling in the mean time? Eventually you will need to go standalone though...

Maybe, but I'd still consider installing a WB O2 though so you can see how the DME adjusts and keep an eye on things.

I can give you a hand if you'd like. It's pretty straight forward. I installed one in mine before I started fooling around with the M30 AFM and 19lb injectors. And two years later it's going to come in handy for tuning my 2.8L stroker which will be running stand alone
