It has 24 teeth and 2 additional pickups 180 degrees apart. As I rushed things and ordered assembled unit with secondary trigger - Hall, I had to stick to the initial plan by using only NE signal from 24 teeth wheel and grind two opposing teeth off. Otherwise, as I understand, it would be possible to use unmodified stock trigger as coil-type trigger together with cam-sync (from one of those additional pickups G1 or G2) as secondary. So, in this case 24 wheel cam sensor with opposing teeth missing is represented as 12-1 crank wheel. '''IAT''' FAE 33160 '''Coolant temp.''' Stock. Green connector on the side of the thermostat housing. '''TPS''' Stock. Using only E2, VTA and VC terminals. '''MAP''' External VEMS 400 kPa MAP sensor with temperature and 5v outputs - both seem to be useless at the moment. '''WBO2 Sensor''' 1) INNOVATE BOSCH LSU 4.2 057 2) AEM UEGO (OLD INFO: I had AEM UEGO kit. VEMS supports specific Bosch LSU4 sensors and it turns out AEM is using the same sensor. Well at least pretty similar Bosch LSU4.2, so I connected it. Very helpful info to figure out wiring: http://wbo2.com/cable/lsuconns.htm. I was able to calibrate it with VemsTune. It appears to work. Compared to the readings of AEM gauge and it showed AFR about 0.4:1 more rich.) '''EGT''' Standard EGT. '''Knock''' Two stock sensors wired but and not used. '''Coils''' Stock three wasted spark coil packs (one coil for two cylinders 1-6, 2-5, 3-4) driven directly from VEMS 3 ignition channels. EC36 pins: 35,33,34. '''Injectors''' LowZ 1000cc RC injectors wired with resistors. '''Fuel pump''' 1)AEM 320. Stock main relay is activated by the ignition switch on, which provides power to circuit opening relay, which in turn is activated by VEMS - EC36-pin15 connected to stock FC wire. http://www.vems.hu/files/Gachax/FP_relays.png 2)Walbro 255. Activated at certain boost level. Not that it's needed, but had a spare one. '''IAC''' OEM stepper valve '''BC''' Pneumatic valve 3way '''TODO''' - Try to get knock sensors working although it might not be possible as they are one wire sensors.
