Thanks for the info. I just bought the Tuner Pro-Bosch a few hours ago. Now i should be able to instal the UTEC and Tuner this weekend. Good to know i got the right one. Now i just need a gauge???

 

Any luck Smoky? I getting everything installed on the 17th and want to get the gauge if it works. (Bitting nails waiting for answer) LOL

EDIT: Also is any thing else we need to wire everything up?

 

Sorry guys...last night ended up a ruckus. It rained this morning but I managed to get out after it dried for a short cruise to verify this..

The AEM reading the analog output seems to report first, then the Tuner display reads the exact same AFR a fraction of a second afterwards. But I've got them reading the same!


BTW, the AEM gauge has many wires. You can ignore the serial output. And the 5v output. That leaves ground, 12v, and then signal + and signal -.

The signal + and signal - wires are brown and orange. I can't remember which is which, but that doesn't matter. Once you obtain the mini-molex connector for the Tuner's 5v analog output (I got mine from TXS, sort of) then you have 2-pins on a plug.

The plug has a clip that secures the plug to the Tuner.

The plug is arranged such that:

^ ----clip
O ----Pin1
O ----Pin2

The AEM's BROWN wire goes to Pin1, the pin closest to the clip. The Orange wire goes to Pin2.

If you connect it and the AEM gauge says 8.22 or whatever and doesn't budge, then that means it has 12v power but no O2 signal power, and you reversed the signal wires.

Cheers,

Thanks for the info Smoky!!! But I think I'm going to pass on the A/F gauge. I've done more reasearch and talk to my tuner and just don't need it. I feel a little bad for being so "pushy" are getting the info from you. Hopefully someone else with use all the work you've done!

 

good info on this thread...subscribing for later use...

 

Finally got the AEM AFR gauge mounted in a nice black metal Autometer (Autogauge) gauge cup on the pillar. No pics yet, but I'm out of town at the moment. It really came out nice though. If anyone is going to get an AFR gauge, until Autometer expands their Nexus line to include an AFR gauge, then this AEM AFR display gauge with black face and silver bezel is hands-down the best match for our Z's interior.

 

Anyone know what pin on the on the molex plug is the 0-5v output? I want to hook the signal to a Blitz SBC iD Color display.

 

The plug I am describing above is the 0-5v output.

 

But which pin of the 2 pin molex plug has the WB signal? I guess one is 12v and one is WB signal?

 

Hey thanks for all the work guys. This is very useful info to me. I was just looking at getting an A/F guage in.

I have been using an outboard gauge with my TXS Tuner for more than 6 months now. I am using the dynotunenitrous.com wideband gauge.......

here's the thread:

I forgot I posted this. LOL Goodwork Quad.

 

One is Signal +, the other is signal -. It tends to not matter how you hook it up since it is binary.

There is no 12v coming from the 0-5v. At least I don't think so.

 

This is from quadcams thread, thanks!

The Tuner Wideband has an analog output (bottom pin of a 2 pin molex connector on the side of the Tuner.) The output sends out a DC voltage that varies from 0-5V.

 

FYI...I use the old PLX Devices guage wired straight to the UTEC 5V output. Works great and the gauge only cost about $80. Unfortunately, they are discontinued and are getting very hard to find. Note, this is not their new digital gauges.
