The Wideband Commander Air Fuel Monitor Install

[03AV8R]

Hey am i like the last person to install one of these?? Just got it done & it appears to work great! Has a nice PC display for my tablet & logs the data pretty easily. I hooked up the A/F of course & the RPM's for now so i can monitor those 2 things. Im holding off on the TPS & MAF voltage hook-ups for now till i gets the new livewire & see what that needs for inputs. My car is running like crap. I thinks i got some condensation in the tank from sitting all winter in the hot & cold garages.. I put the stock MAF back on & am starting the whole tuning thing over again with a stock setting currently.. Still running pretty crappy.. The stock MAF is more than enough for my power level so im gonna try it again first & tune from there.. I really like this A/F monitoring device. Cant believe i went this long without it!

If anyone wants a step by step of what & how its installed i could prolly take some pics & lay it all out for ya?? Im thinking everyone wanting an A/F monitoring device already has one though! I thinks i was pretty late in the game here..

First i had a "Bung" welded onto the end of my longtubes (while in the shop doing the rear end) just below & behind the 02 sensor.

Then the A/F sensor screws in to get its readings directly from the out-going exhaust. See Pic

Then i ran the wires for the sensor up thru the floor thru a hole with a rubber grommet.

Next you hafta connect the sensor to the commander box & run the 12V power lines to a "switched" 12V source. I used 1 of the hot wires behind the Fog/Traction control/Rear Def panel that was indeed only hot when key was on. This will ensure you dont drain your battery when not in use.

Next was hooking up the little gauge that comes with the unit. Its pretty simple. Both pieces i decided to tie-strap & mount near each other using the Glovebox door bar which was removed recently.. The gauge is only a temporary thing ill be removing once the Livewire is installed. I dont like gauges cluttering my dash.

Another step is finding an RPM signal for another connection you will make to have RPM's displayed with the A/F.. I used the line coming off the computer #26.. Seems to work OK & didnt hafta run wire thru the firewall..

A final step is installing the software on a laptop, tablet or whatever you gots lying around with a USB port.. Hook up the USB cable & start your engine.

There are 2 sets of analog inputs you can use also for TPS or MAF readings. Ive not done those yet & probably wont till i see how the Livewire works

Thats pretty much it outside of finding good grounds where needed..

Nice info, I went with Innovate system. It was the same process except I put my sensor further back on the h-pipe (in prep for TT) and ran the lead in thru the shifter boot via a dent in the boot ring and homemade seal. I was able to hide the LM2 and wiring in that area around the shifter. The software is about the same and I have not made the interface for the Xcal2 yet.

I think these are GREAT --- beats the HEII out of plug checks.

Great post! I STILL have to get one. haha...
