Jumptronix A/F meter

[Van]

I got it from RRE for $85. It is black, and 1 7/8" x 1" in size. This unit can be mounted just about anywhere because of its uniqueness and small size. Display is backlit in a greenish light. There is a switch on the backside that will enable you to read battery voltage if needed. Hook-up was really easy, 3 wires: power, ground and o2 wire. You can hook this up directly to the ecu wiring or drag out the o2 wire up in the passenger side kick panel like I did. I already had an egt gauge when I got this unit, and I must say it is really nice to be able to correlate the two readings together. I chose this over the blinky light gauges, even modded to be more accurate. I want to look at it and see the exact digital readout of the voltage at my o2 sensor. RRE also has wiring instructions at their website to help with installation. In my book this is a great gauge for: price, exactness of readout, size, ease of installation and dual purpose of gauge if needed.

My buddy with a 95 GST has the same gauge. He swears by it and I've seen how it works. Easy install and pretty good accuracy. I've been trying to get one myself but RRE is always out. If any of you guys happen to be lucky enough to come across these, please buy 2 and I'll pay for one of them! Thanks!

hey spltscnd98gst, I just got my Jumptronix from RRE today. I ordered it last week so they do have some in stock now. I'm going to install it right now and see how it works. Later,

If anyone is considering the new Apexi Super AFC, you can do the "blue wire" mod and monitor your O2 volts with the AFC. You will get the same results as the Jumptronix meter.

[spltscnd98gst]

is that true with the S-AFC blue wired mod? I've never heard of that? How do you do it and are there any issues as to which is more better or reliable? Thanks!

Yes, the blue wire mod works with the AFC with no problems at all. You just have to tap into the same wire you would for the Jumtronix or A/F guage. The voltage readout is the same as the Jumptronix, acutal numeric values. It works excellent and eliminates the need for a Jumptronix and the unaccuate A/F guages. Just make sure you display the AFC where you can easiy glance at it.
