One more of the ready-made EFI controllers is VEMS. My impression is that it is a bit cheaper than Omex or Emerald.

Building the thing was easy enough, and its good quality board, its making the software work that prooved frustrating and having spent several years working on ecu calibration for oem's you'd have though that part would be a cinch. Its trying to be all things to all engines and that making it too complicated. Trying to make all different sensors work with each other just and never being sure whether its something you've done wrong became too frustrating. I wanted something that would work so I could just get on and play
Most stuff is surface mount now so not really diy-able.
Happy with the way I went in the end but sure could have saved myself some time and money.

im running my saab engine off a ms3. its been a brill bit of kit. the best tip i can give is if you dont have a month of evenings to learn all about how it works reading the manual and forums dont bother. i started reading up on them easily 6months before i even built mine and to be honest the whole thing was a doddle.

just sign up to msextra that is the best ms forum by far.

as for your crank wiring just wire the sensor up as it shows in the ms manual. if you dont know what pin is what on the vr sensor just look it up on the bosch (manufacturers website)

little tip. your tooth angle will be 114deg not 20something degrees like the vauxhall forums suggest in their guide. found that out on ben copelands redtop when we did his ms2

Baz cheers for the info i am singing from the same hymm sheet i will get there with the wiring it will not beat me i was quite happy i got the ms to talk with my laptop and configured the throttle etc etc. ive been spoilt in the past with honda wiring diagrams & wiring this gm ( german haynes diagrams ) have been a right challenge.

Ash My engine runs iff the siemens stuff and i cant for the life of me find the info on any forum ! I got miffed and gave in today with the bike shockers i was going to use bit of retail therapy and ive a set of protechs on the way ill use the bike shockers on the next toy for the kids !!

I can see light at the end of the tunnel !!
