    '02 WS6 A4 Wideband through EGR?

    I have searched a bit to no avail...be kind.

    I have an '02 WS6 A4 and wish to log my Auto Meter (Bosch) wideband in Lambda into the ECU and HPT. I have no HPT pro and need some direction if and how this can be done. Wiring inputs would be appreciated.

    I can scale the 0-4v output from the wideband and develop the cfg and histos ok, just need some wiring connection tips, ect.

    I prefer tuning in Lambda coming from the turbo LNF world and running a not so common ethanol blend of 47 to 60%. (Stoich is 11.25 afr on E60)

    Spent the last summer toying with the WS6 after selling the LNF Cobalt SS and need some guidance. It had a Superchips tune on it and I have shaved 1.2 sec off the 60 - 100 time tuning it so far but need the wideband wired in so I can safely lean it out some and get it dialed in. Cam and springs this winter so a WB is a must. TIA.
