I found this gauge that uses a linear 5v input for AFR..

It appears to match the output of the Tuner's wideband 5v output pretty closely.. Turns out it'll work with any UEGO output that measures stoich (14.7:1) at 2.35 volts.. (the higher the voltage the leaner it is)

The main advantage of the TurboXS Tuner Pro over any other UEGO is that you can calibrate the output to match any device you want to send your output to.


I just ordered one in black and will test it out.. But its a nice alternative and means I can now hide my Tuner away in the glove box..

And even better, it matches my existing gauges almost exactly...

 

Just so you know.. The Tuner's 5v wideband output needs to be adjusted for.. Not sure if your using lambda mode what the settings should be, but they should be scaled appropriately.. Since the start point, and end point sets the ramp..

AFR
0v = 10 (factory is 9)
5v = 20 (Factory is 25)

This will calibrate the output to work correctly with the range of the gauge.

And even better.. This gauge was under $150 including shipping..

Much cheaper than the FJO and Link Digital gauges which may or may not have worked.

 

Yeah Jack, definately post up when you get some results on this gauge. I'm very interested in it.

 

Jack,

Pretty cool idea. Keep us posted on how it turns out.

 

Nice, if only it came in 60mm.
I would have to get an A-pillar for this.

 

nice

 

In your case you would use this...

and this

http://www.plxdevices.com/NB_WB_GaugeConv.htm Which is a wideband input to narrowband output.. so you can use ANY narrowband gauge as an accurate wideband gauge... but Nordskog is my second favorite design and one of 3 sweep style analog gauges in existance.

 

I wanted something illuminted so I can catch the state quickly in the corner of my eye.. which is basically the only reason I chose not to use the norskog gauge..

 

OK.. quick update for you guys.. Hooked up the gauge to the 5v output on the TUNER, initially it was reading slightly off, like I said earlier, you seen to set the output calibration an AFR low (0v) of 10:1, and a AFR high (+5v) of 20:1

Once the output is calibrated and the gauge is dead-on.. I found the refresh was slightly slower than the Tuner's display, then I realized I had the old flash and reflashed the Tuner, now the refresh is at the same speed as the Display. I can now hide the entire Tuner box somewhere out of sight.

Currently I have the PLX Gauge in my cubbyhole until I decide where I want to perminently mount it.. I need something line of site, so I may mount it in a custom vent setup I'm doing, or pillar mount along with the EGT gauge...

The overall install took about 15 minutes to do once I had access to the wiring, I wired the +12v and Gnd wires to the same place that the Tuner is getting its power source from, and connected the white wire to the 5v wideband output on the Tuner.. Real straightforward.


This is a definite MUST-HAVE if you need a clear digital/analog gauge for your tuner. It visually looks alot like the AEM gauge for the UEGO wideband. It cost all of $130 (which is a bargain for a gauge like this)

 

I got all excited and then realized that my Tuner Lite does not have a Analogue Output. Bummer!

 

Doh! I didn't even realize that..
