HFS3 wiring ecu area
 

Evening All

i am struggling a little here.

i have installed the kit on my rs4 b5 2000 model, me7 ecu.

i have done all the wiring and the kit is working fine, i am now on to the next stage of mapping it in. and my goal is to get a signal to my laptop for logging. i have been told to use the orange wire to the rear o2 lambda input for the signal. I have done this and it has not worked am i doing this correctly?

Also on the same harness i have no connect for the yellow wire or black wire, do they need connecting to for the Orange wire to work?


thanks

What signal do you want to log?

Orange wire on the grey harness is a map switch wire.

0 to 5v i have got it working if i put the jumper on fs0 but wont work on fs1

My over all goal is to see it activate on logs for remote mapping for my file writer

I am not sure what you are trying to do.
FS1 and FS0 only changes state upon failsafe activation.

Rite OK I may be way off the mark here.

First of all where is the orange wire meant to go?

Secondly my main aim is to get a voltage signal from the grey harness into the ecu. So I can log when the meth is kicking in.I know I have the gauge but my file writer can't see this.

Thanks for your help.
