I'm thinking about putting an AFR in my clock delete dash hole like this analog unit, looks like a decent period look match.

Anyone running one and what make?

I have an Innovate system with O2 sensors in both headers. It's digital and doesn't match the OE gauges, but it's a track car and I don't care about that. The gauge only displays the reading from the sensor closest to it in the daisy chain, but when the laptop is connected it shows both sides. The engine is carbureted so I can change jets in really hot weather if it gets too rich. Generally I use the system to check A/F at idle, to achieve good balance and minimize backfiring. It was very useful for initial set-up so I could choose the best main jets. It would be equally useful on an injected car to get the best adjustment on mixture.

My thoughts too...I'd like to know what's going on under load and not just an idle number since I'm running a stock 9.8 comp in my 930-10 and it is in a hot environment.
Rather than just fatten it up as I've done now I'd like to find a sweet spot for safety and performance.
I have SSI's on it so it'll just be a one sided affair but I guess that'd be good enough for street use.
That and it is just fun to know what's going on with your combustion process.
Where did you plug into a power source and what was the required amps?l

KILRWAIL

I took 12 v from the hot side of the three-fuse block at the ignition module. The spec calls for a fuse in line and from memory I think it was a 5 amp type in a pigtail that I spliced in.

Thanks....I don't have the unit yet but that sounds as good as any.

The AEM Electronics UEGO wideband is a great choice and I have personally utilize this unit on several projects. They offer accurate monitoring of air/fuel with the included Bosch wideband sensor and best of all does not require free air calibration, like many others on the market.

If you are in need of one, I would be more than happy to assist you with a kit for only $209 including shipping to the Continental USA or $159 for the AEM Electronics digital display UEGO wideband. I will PM you for further information.

Julio,
Thanks for the note.
Bisimoto made me a deal on an AFR that beat any price I could find by a considerable amount.

BisimotoSales

Thank you for the kind words Pat. If you are in need of anything in the near future, please do not hesitate to ask. Thanks.

Julio,
Ok, then stop by and put the gauge in for me......

BisimotoSales

Hahahaha, I would love too. Just cover my flight to AZ and I will installed for you ASAP.

Got it in and running, not to bad a deal....routed the sensor cable thru the tunnel, the only surprise is you have to drill a hole on the underside of the dash to access the gauge cluster...the cable is 'just' long enough for that route to the far side of my left SSI.
Interesting watching the afr/co change depending upon load...the gauge maker AEM claims an accuracy of +/- .1 on the AFR scale.

Looks great! It flows very well with your factory gauges.
