Please measure the MAF pins in the harness
- which AANpin it belongs to (fill in table below)
- any pin connected to ground must be avoided.
- Is there a +12V pin (capable of 2..3A) for heater+ ?
We recognized that the MAF connector is simply unsuitable, because we need 4 pins (neither must be connected to GND or +5V) which is simply not available in the MAF connector. If we find 3, that, together with the NBO2 nernst signal might be enough.
Anyway, finalized pins to use for WB02 LSU4 sensor:
- AANpin...#42 (open on stock harness) pump-
- AANpin...#37 (+12V supply-flyback, voltage supplied by the AAN harness, NOT the ECU like on the 3B)
- AANpin...#43 (open on stock harness) nernst
- AANpin...#51 (open on stock harness) pump+
- AANpin...#54 (open on stock harness) heater-
- not used
Using these pins we wouldn't use the MAF plug, but would allow there to be enough inputs for the WB02.
In the meantime, review VemsAudiAan
You can do the verification measurements,
I am testing this ECU for Brian on my stock 93 S4 and am having major problems trying to interface with megatune. I downloaded the latest megatune from this site, uploaded (and verified) the 1.1.23 firmware and loaded the config posted by marcel but the config will not verify. An error message comes back on the verify stating that there is a flood of charachters on the serial line. this is with or without a reboot of the ECU inbetween firmware flash....
