I installed my Speedhut boost and AFR (AEM compatible) gauges, AEM wideband with Bosch sensor, with the sensor mounted downstream from the Cats. I understand that this sensor placement will slightly skew the AFR readings; however my AFR is hovering at 10 on idle and drops to 9 on WOT. Includes: The 52mm (2-1/16") Wideband FAILSAFE Gauge includes a Bosch 4.2LSU AFR wideband sensor for monitoring and feedback of AFR and an on-board boost sensor to read vacuum or boost pressures up to 30 PSIG. Both boost and AFR can be displayed in real time on the gauge's face using the full color OLED screen and 24 three-color sweeping LEDs. If you have ethanol in the car the ProEFI wideband readout will adjust itself to read the different stoich set point. The AEM gauge will never adjust its readout. example: If your on E85 and targeting 9:1 AFR the ProEFI wideband will display 9:1 and the AEM wideband gauge will read 14.6:1

3. If you plan to keep your ac you need to come up with a way to switch the wideband output on only when tuning or reading off the wideband. Then back to normal operation when not using the wideband. A simple 3 post switch, 2 input 1 output, will do the trick. The wideband output will be one input, the red and black wire you just cut will be ...
Hey! Matt! hows it going... I installed my AEM UEGO Wideband and everything is working well except im a little confused... I bought a RS232 port, and ran the wire (not the 0-5v one but the other one I cant remember the name of it right now) to the RS232 port, and the other pin to ground.

Last year I had a lean condition that I was trying to track down. The fuel pump was failing, so I changed it, and I got my fuel pressure rise back. O2s were still in the 600s. I wired up a new heated O2... Can someone explain the difference between the PID, Desired FA Cyl 1 (AFR) and the reading I get on my AEM Wideband guage during WOT? The Desired FA is a constant value (Straight line) when my AFR's are reading 12.5 (Straight line) and everything is good. Is the wideband ran independently form the ECU ? Do I keep my NB connected to the ECU. Is the wideband only use when tuning? I just got nistune and I cant find pretty much anything on how to connect the wideband to the ECU, so to me .I dont need to.Does the ECU take any advantage of having the wideband wire to it?

I went into the scanner and checked to make sure it was the latest update and I setup up the channel to the MPVI2.1 analogue signal. Then transformed the reading to AEM-4110. It shows up properly on the AEM wideband output wire? - posted in Advanced Virtual Mechanic: I just bought an AEM uego wideband that has an output wire that runs 0-5v or 0-2v. My question is can i use this to substitute my stock 1 wire o2? 2v or 5v? Will the ECU like or dislike this setup. Im just wondering cause I just spent $200+ on it and $260 on the maft kit and dont want to spend more money on another o2 sensor. I ... Well I have a AEM, and don't recommend that.

At idle, it should (provided the car is tuned correctly), show 14.7AFR (if yours shows 15 at idle, it could just be that the sensor is not calibrated, the voltage to AFR config is wrong, or the idle ... The rest of the deviation can come from the programming as well. There are tables were we can tell the ECU the O2's are not reading correctly. IE, if the programming says that at 2000RPM / low load the O2's are reading 5% richer than actual, the ECU will take that into account and adjust fueling accordingly.
