(not logiclevel) ? ** A: they are logic-level, 5v (not sure if its postive (+) though) ** Guide for conversion from original POS/coil to COP here: ** http://www.bonnquattro.se/aan/18tCoilPackConversionInstructions.pdf Next goal: * switch exhaust header * another turbo * larger injectors * another WasteGate * switchable fuel maps What I know: * I will buy the assembled vems with econoseal connectors * I need 5 logic outputs for the ignition, would like a 3+5 version * The extra flyback 30v diode seems like a good choice * I will buy a wideband lambda * I will buy a EGT sensor * I want the LED (4x20?) * I want a special lambda display * EGT and knock sensors(would like to use the stock knock sensors) * onboard MAP sensor 400 kpa * I will buy some econoseal connectors 18+36 * Primary trigger Is VR * Secondary trigger would be "audi trigger" What I dont know: Q: Shall I order 2+6 version, what can I use the 2 high current outputs for ? A: Lots of things. Relay, solenoid, NOS, ... Q: How about firmware and sensors, do I need to compile something myself ? A: no need to compile anything. See VemsTune Q: I suppose I should choose PS2 connector as well A: useful eg. for wheel-speed input (but we can connect PS2 clock signal to an unused pin as well Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
