Easy install, P/G and one o2 wire splice.

Red one is a voltmeter that GG made.
Light bar all the way right is rich.
All the way left is lean.
Middle is good, or 14.7:1 air fuel ratio I think. Probably part throttle cruising.


Really cool little thing.

I believe only one bar is green at any one time and moves left to right depending on if you are running rich or lean. The red one is most likely a volt meter. George graves work is top notch and 100 is a good price.

So this works with the factory o2 sensor in the exhaust? If so shoot me a pm with ur PayPal info.

It can be set to read in a single bar as shown, or full like the voltmeter on the left. It's showing rich in that picture because I just got a new o2 sensor and didn't want to splice into it before sale.

I don't think he offers these anymore, and they're far and few between.

Three jump splices, power, ground, and one o2 sensor wire.
