These use special "auditrigger" 3 sensor trigger system with the 135 tooth flywheel teeth VR, crankhome-VR and cam-HALL sensor. The factory MAT (manifold air temperature)-sensor is PTC type, so 430 Ohm pullup resistor is used for better precision. Bosch made many motronic ECU-s with this connector, but different (incompatible!) pinout. Other engines already tested with VEMS motronic55 boxes: BMW inline 6cyl (M20B25 and M5) Peugeot (106 GTI) Porsche (usually with 60-2 crankwheel VR sensor) tested with harness-adapter loom (with standard Econoseal36+18 VEMS and adapter outside). If you have such an engine, make your project page(s) from wiki MembersPage so we can help verify the application, pinout and other aspects. the default 400kPa MAP sensor is a good choice, but if you want other type of MAP sensor (none / 115kPa / 250 kPa / 300 kPa) than write on your wiki MembersPage, and paste the link in the order note. as the factory setups have no WBO2 (Bosch LSU4 wideband sensor), and WBO2 needs min 4 signals between ECU and sensor (the sensor has a 5th pin for supply and 6th pin that need not be used if the more precise software adjustable calibration scheme is used), a few wires must be used for WBO2. It is often simplest to pull in a few wires in protecting tube to the cabin, while others prefer to hijack some non-used wires (like the MAF-wires, when they throw out the MAF sensor). For this, or any other special wish or preference write on your wiki MembersPage, and paste the link in the order note
