Hi

I have an Audi urS4 1992 with the AAN engine.

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.

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
