Curious if any are / have used this digital A/FR gauge. Costs $199., with Ox sensor, may be a good gauge for the $$. Thanks!

Can't speak to the AFR gauge but I've got their Oil Temp/Pressure gauge and I'm happy with it.

When installing it I had a question and called them up. They went out of their way to provide great support. Because of that I'd buy more of their stuff if I ever needed it.

I am using both. Good units. Get the heatsink bung to make your o2 sensor last.

Feel free to ask any other installation questions. peacb

Motard, is the heatsink bung something from innovative? Please explain for me. Thanks to both of you for reply's. I have added a Katana, and while it is all buttoned up, I was able to buy a PPE header and test pipe, which will go on maybe next Winter. I figured I should install the A/FR gauge to make sure I don't need a retune on the Charlie X ECU that I am running, once the header goes on. Thanks, Tom

Have you looked at the PLX wideband SM-AFR?

I have one in my Turbo Esprit, been working great. I'm adding in a boost sensor and a dual fluid temp sender to the same DM-6 gauge, wich works great since you don't have to run any extra wires.

Makes sense; the PPE test pipe I got has a 3 in. extension tube for the 02 sense. in the U bend position., must be it. Thanks

I run the AEM UEGO gauge. Dead-simple install (built in control box) and looks / works great. Also a bit cheaper than most of the competition. Comes with a black and a white face so you can swap it out (i run the white face on mine).

I had 2 mtx Innovate gauges that I replaced with the Aem unit after problems with the Innovate. It kept loosing connection with the sensor, replaced the wiring still had the problem then replaced the gauge and it was good for about a year then the problem came back. Have had the aem for a few years now with no issues.

Jeff and Moldy, the AEM looks good, as I need as simple as possible; no need for data logging, etc. Basically, I want to see what ratio's I have, to make sure change to header/decat doesn't lean me out too much. I'm running Charlie X tune from a few years back, and only mod is Katana, with PPE, decat, and Rapture muffler. I have the impression the tune was set pretty rich, to protect guys who keep modding without checking whats happening to A/FR's, so expect I will be OK. Simple read-out, and install, (and $$), all look like what I want. Thanks for all the responses!

I've looked at lots of gauges and I think I'm going with:
PLX Wideband O2 Air Fuel Ratio SM-AFR V2 + DM-6 Multi Gauge Touch Screen Kit

I'll post a picture tonight of my gauge setup. Just a simple boost gauge and an A/F gauge near the shifter using the BWR pod. People who have been in my car think it's just a stock cluster since the faces and even the lights match at night (on a 2005 at least).

I've actually have the AEM as well and am happy with it. It's connected to my Series 2 ECU so I've got data logging as well.

I can't imagine a use for it going less than 10:1 though. Are you using pure Ethanol or something? Cause if your gasoline based system is that rich you are damaging your engine by flushing the oil off the walls of the cylinders with all that extra fuel.

I'm looking forward to seeing your setup. I was considering the same. Thanks for the info:bow:

Here you go, sorry for the delay. The colors on them look slightly off between the two because of the flash (it's dark in the garage / with the top on), but in person they are nearly identical for the bezel color and the face.

I Installed a little switch on the side of the cluster to control the lighting because I got lazy when wiring it up and didn't want to tap into the headlight power. I just leave the light on all the time since you can't see it during the day anyways.
