I contacted Mattias about setting up VEMS on my BMW 535 (E28) on which I has a twin turbo setup. More information here (in Swedish): http://www.535twinturbo.com/

I previously ran with SMT6 but that was just crap.

Engine information

Trigger setup

The stock reference and speed sensor are not useable with VEMS as far as I know, these are mounted at the back of the engine. One measure engine speed through 360 teeth, the other syncs with the engine once every revolution. So it's kind of like a missing tooth setup - only it isn't.

The solution that will be used: Three M8 bolts will be fastened to the harmonic dampener at the front of the engine, 120 degrees apart with 8 mm protrusion. A Honeywell GT1 Hall sensor will be used to sense these.
