Hey guys,

got myself an air/fuel guage from autometer and was wondering if anyone has had problems installing this/ wiring into the loom for the oxygen sensor????

got the diagram on the guages box for install, but was wondering if anyone has done this themselves and whether you've got any tips for this install!!

Cheers in advance!

YEah I did it.

Tap into positice & negative under the dash.

To get your O2 sensor signal , i THINK it's the middle wire off the O2 sensor - best to check though - USe a DIGITAL mutimeter and find which of the 3 wires to the O2 sensor is fluctuating voltage (millivolts to like +3 V as I recall )

Also, try a search - that's where I got my info from initially.

I tapped in mine close to the O2 Sensor cause I couldn't be bothered finding the pinout on the ECU.

Good luck --

Oh and BTW - the AFR guages are not really that accurate (actually I think it's the O2 sensor) - Eg: when I got mine dyno'd the lamda prope told us 1:12's (i think) but the AFR guage was reading super rich - go figure -

It's really just a guage - I only ever rally look at mine if it is reading lean - which it never has under load.....

      And 90% of the time those people turn out to be wrong anyway. But they still treat themselves as a victim...

      I used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it

      Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare.

      R32 gtst speedo out by 10kph

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.
