Summary of change:
(This page will eventually move to it's owners MembersPage.) Fredrik Eriksson contacted me about setting up VEMS on his BMW 535 (E28) on which he has a twin turbo setup. More information here (in Swedish): http://www.535twinturbo.com/ He previously ran with SMT6 but found it couldn't handle the engine and requirements and has decided to get an assembled VEMS/Genboard. '''Engine information''' * Mostly stock M30B35, a 3.5 litre 6 cylinder engine with ~210 hp N/A with stock engine management * 2 x Garret T3 from Saab NG900/OG93 * Custom exhaust manifolds * 2 x EGT K-type thermocouples in the collectors * 6 x 380 cc/min high impedance injectors * Single coil and distributor (for initial setup, direct-fire setup might come later) '''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. The primary and secondary trigger inputs should be of Hall type. '''Questions about the assembled v3.2 controller''' Some things seem to be left out from it. Q: No serial communications jack seems to be present on the assembled controller. Is it up to the customer to decide which method to be used and realise it? Q: 2 x AD597 chips are a requirement from this board, are those an additional cost? They aren't listed in the web shop page for the assembled controller. Additionally, are K-type female ''chassis'' connectors available through the webshop?
