I'm new here and on a mission. I have no GN or TType but I'm thinking about installing a full GN engine management system into my now, twin turbo BMW 635. The BMW's ecm is one step up from an abicuss plus I like to horrify the BMW purist. First, are the cam and crank sensors "Hall" effect or inductive? Also, are the VSS and gear switches vital to the ECM's proper function?... my car is a 5 speed. She's down to 3300lbs, has 1 of 16 Cartech twins on her, a Saab APC system and a bunch of home made parts... boosting to 20psi right now and, well, it's my commuter car. I much appreciate any info I can gleen from you guys. Cheers.
The crank and cam are both Hall effect, the VSS and gear switches aren't vital, but they do "play" in the scaling of boost, lean cruise, etc.
Sounds like a killer project! Be sure to look at the various sections of the Technical Articles (http://www.gnttype.org/techarea/techpage.html)
Especially the ECM sections:

Thanks, Ken. That's good news! A few more questions... Does the crank trigger wheel have only one trigger point (window) and if so, how many degrees BTDC on cyl 1 is it (assuming it's for #1)? The cam sensor... flying magnet or "window"? This is registered to #6 cyl correct? Do you know it's relation ship, ie. degrees from TDC #6? Thanks again! This is looking more and more feasable.
