Just bought a mpvi2 and looking for an wideband o2 to hook up. Only one on here is for CAN BASE system 07 and newer. Everything I'm working on is 99-06 LS engines. Any one got suggestions

You need to buy the pro external wiring harness kit or wire them in through the egr port. Early ecus don't support the can wideband last I checked
All standard wideband should have a 0-5volt signal which is the one you'll need.
I have the pro link wire harness that plugs into the side of the mpvi2 just looking for suggestions on a o2 sensor I can wire into the pro link
I bought an AEM Xseries and it works great with the prolink
Are you using it on 99-06 gm stuff that is NOT can based
Are you using a gauge with the sensor?
I am using mine on a 2003 Tahoe turbo 5.3
I use the aem 30-0334 for all my in house tuning and on my personal vehicle. I try and get my remote guys to invest in the setup as well. With the MPVI2 with prolink getting the CAN signal is easy.
Just my $.02
if your looking for analog you will use the black to ground and the red on the prolink unit, on the wideband if it is the 30-0300 I am using the white and black. I also have the pro upgrade so i don't have to wire into the egr or ac circuit.
I have the 30-0334. I was trying to do analog, but just rewired it for CAN to try DHC's idea. Still nothing showing up on the scanner unfortunately.
yeah I have the pro feature set
It should work,only hookup the wire your going to log from, do not hook up everything to the prolink. If your looking for analog only use the analog 1 input only. If your looking for can use those 2 only. Another thing did you resync your unit after the pro feature upgrade? If not you need to.

I'm having the exact same problem, I been fighting with this over a week. I have all the same kit he has, pro link, its updated, using aem 334 WB. Im using the blue wire and black wire and it will show up when the car isn't scanned but soon as I scan it, it disappears.
early ecu does not support can activity.
you can use the 5 volt + signal with the pro edition. you would wire this to the red-analog 1 wire of the pro harness.
the white wire 5v range positive which should be connector A port 9.
the white wire requires a channel transformation by using the given equations
0-5V Analog Output Scaling Formulas:
AFR = (2.3750 * Volts) + 7.3125
Lambda = (0.1621 * Volts) + 0.4990
for external recording options the rs232 DB9 connector can be used with any interface software that uses this style of com port. you must wire the blue rs232 connector A port 5 wire to pin 2 (Rx) of the DB9 connector and pin 5 (Ground) also must be populated at a minimum.
if it doesnt read then you need to calibrate the com port settings to make the com settings match the aem com rates:
baud rate 9600 bps
data bits 8
parity None
stop bits 1
i dont know enough about vcm to know how this is calibrated in the scanner if possible.
2000 Ford Mustang - Top Sportsman
Here is how mine is hooked up to my AEM on the wideband white is hooked to the prolink red the brown is to ground and the prolink black is to ground, in the vcm scanner I add a channel to log my eq ratio error.
send me your channel config file
