BMW M73 V12
Engine information:
Customer query:
I have a 1984 BMW e30 that I am putting a M73 V12 twin turbo in and I am looking to buy one of your systems that can run it. Please advise what you believe would be the best system to run in this from your company as well as pricing and availability
1 [VEMS ECU] can drive it if it has 12 high-Z injectors
- 2 high-Z injectors in parallel is fine
- ignition options:
- use the oem twin distributors
- optionally use wasted spark coil (either active coils driven by logiclevel ignition outputs or passive coils driven by IGBTs)
- or last option use 12 active COPS
- choose 2 knocks
- also request "2 WBO2 and lotsof extra inputs and outputs on extra EC10 connector" in the order comment (to have some extras above the bare mnimal)
Primary Trigger (crankshaft, most likely 60-2)
VR or HALL ?
- if you find 2 pins that measures same resistance in both directions (usually between 300 and 1500 Ohm) that is VR. Otherwise HALL
Secondary Trigger (camshaft)
VR or HALL ?
- if you find 2 pins that measures same resistance in both directions (usually between 300 and 1500 Ohm) that is VR. Otherwise HALL
Twin Electronic Throttle bodies
- ETC if present should be removed and retrofitted to normal (cable operated) throttles
- according to information on: http://www.meeknet.co.uk/E38/Pdf/EMLIIIs.pdf your engine is equipped with it.
If it has 12 low-Z injectors, or 24 injectors (most likely not), or some other special requirement than 2 VEMS ECU-s can drive it (some considerations apply, eg: no MAT, CLT pullup on 2nd VEMS ECU )
