cranking problem, BMW with M50B25 running MS I v3

Postby AllarN » Thu Aug 28, 2008 8:52 am

hello,

i have a strange problem with my MS I v3 on a BMW 525, M50B25 vanos.

when im cranking the engine, i get a rpm signal at 3500 rpm...
I have dubbel checked all the wires and the vr sensor is working.

the box is made for vr sensor and six coils and tested with stim, so it should be working fine.

Check your RPM wire and make sure it is soldered well ,

you have to get the VR-'table' right,
you have a 60 trigger wheel teeth
you have 2 missing teeth
you have 20 skip teeth (every 20 teeth a ignition fire at 6 cilinders)
and you have problably 14 delay teeth (between the 2 teeth missing and TDC Cyl #1)
it worked for me last saterday,
to bad i only worked with a MS-2, code 2.88, v3
but it works and it is a BMW 6 cilinder engine,
sooo. get yourself a MS-2 ;)
