Visit Preferences to set your user name Summary of change: 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''' * Mostly stock M30B35, a 3.5 litre 6 cylinder even-fire inline (not odd-fire V6) 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. '''Assembled v3.2 controller wishes''' * '''both primary and secondary trigger inputs should be of HALL type'''. * MPX4250AP 255kPa MAP sensor mounted onboard, with frontplate mounted pneumatic connector. * Serial RS232 and LCD through front endplate. * PS2 through EC18 * 2 x AD597 chips (normally they have to be added to the order and mounting is free ** 2 x compensational cables through the frontplate, flying loom style ** 2 x K-type female chassis connectors (mounted by me) ----- 050926 Problems of the day EGT sensors dosent work, just show 16c when engine off, and when engine ON it jumps between 16c and 60c Is it just switched plus and minus or what? Lambdan act a little strange and unstable, yesterday it work perfektly but tobay it just "freezes" at like AFR17.95 Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
