Summary of change:
Hi I have an Audi urS4 1992 with the AAN engine. http://www.bonnquattro.se/images/eja/bild1_400.jpg http://www.bonnquattro.se/images/eja/aan_1.jpg My goal is for now: - use all original sensors - replace the MAF with a MAP - replace the original Lambda with a WideBand - make my own electrical loom/harness for the engine, using VAG OEM connectors and use the standard Econoseal connectors on the Vems. - Make the engine run nice and good. * make it work with COPs from 2005-2007 VAGs ** is that power-input ? (not logiclevel) ? Next goal: - switch exhaust header - another turbo - larger injectors - another WasteGate - switchable fuel maps What I know: - I will buy the pre assembled vems. - I only need 5 logic outputs for the ignition. - 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 What I dont know: Q: What version of the hardware do I need, what to order ? A: asembled controller, either econoseal or motronic55 connector. 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: Primary trigger ? Is that VR on Audi AAN ? A: VR Q: Secondary trigger, would be "audi trigger", yes ? A: "audi trigger" , yes 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
