Default AEM or Innovate Wideband

Just purchased the Invidia downpipe with 2 O2 bungs, now I need a wideband sensor set up! I'm looking at the AEM UEGO and the Innovate MTX-L Plus. Which do you recommend?

Also, I'm going to need advice or a guide on how to wire it. I haven't installed one before so I don't know how to route it and how to get it into the cabin. I would like to set it up to work with my Accessport as well. Please help!

I went through 2 innovative widebands. Complete junk. Controllers failed on both of them. Constantly needed to be calibrated.

Oh are you serious!? So AEM? That seems to be what everyone uses

AEM. Especially since they are now using the Bosch 4.9 sensor.

AEM seems like the way to go.

Can you wire it to work with Accessport? Any advice?

You will need some items specific to set it up within the AP but essentially... Isolate the oem rear O2 circuit. Run the AEM's 0-5v output signal to the ECM using the oem rear O2 circuit. Set up AP features to use the rear O2 signal. Scale it to the AEM chart in the corresponding UEGO manual. Now you can view your WB on the AP screen as well as add to your datalog parameters.

I have both the AEM uego and the Innovate MTX-L in different cars. I like the MTX-L more. It has a faster response than the AEM. I don't datalog with the aem since it is in a carbureted vehicle but the mtx-l syncs right up with romraider logger. I haven't had any issues with either unit and they both seem to be accurate. Been running the innovate for 6 months, aem for several years.

Sounds like some of that will be done by my tuner. So you can't run both O2 sensors at the same time? Wouldn't it be beneficial to use both for data logging and tuning?

You haven't had any issues with the Innovate? To be honest, they both seem like the same product but I like the gauge for the Innovate more than the AEM.

most new units regardless of mfg will be using the 4.9 sensor now. and some are even moving to the even newer ADV sensor.

personally i run the Spartan2 OEM from 14point7. good response, and i didn't mind wiring it up myself. a hell of a lot cheaper than the big name offerings.

my biggest gripe with AEM and Innovate units are that they have unnecessary round gauge displays. you only need a small LED segment display (or no display at all if you just wire it into the AP). on my setup i have the 0-5V signal split, one wire to the rear O2 plug to be datalogged by the AP, and the other running into a microcontroller that's converting to a digital signal and sending to a small LED display for real time.

I like the idea of splitting it! I'll have to look into that!

I think he's saying to log with accessport you need to connect the aem output to the rear sensor wires(since rear o2 is not used for tuning, only front). Sounds like you can't log external sensors with accessport but I don't have one so I don't know. Tactrix cable with Romraider you can log all the car's sensors plus external sensors and don't have to hook wires together under the car or scale voltages.

The only problem I had with the innovate was initially getting it to sync with romraider. Most of the time it would not work but randomly would but it was not the fault of the innovate unit. The DB-9 to usb adapter cable I purchased was crap. Bought a more expensive one with the FTDI FT232R chipset and it works every time without issue.

To be honest, I won't be using Romraider or anything so I'm not really worried about that. I have an Accessport and will be taking the car to someone to get it tuned, assuming they're using Accesstuner

The AP can log any 0-5V signal you give it. It really doesn't matter what it is. If you have some random 0-5v sensor that the AP doesn't know what to do with (like say EGT or something) you can still input the signal and log the voltage directly, then do your own calibration curve conversion in post analysis of the datalog. I'm currently logging fuel pressure and Wideband O2 by feeding the signals into the ECU directly and configuring the inputs in the AP software.

You can feed 3 different 0-5v sensors into the AP on the following inputs:
Rear O2
Right TGV
Left TGV

Ahh so if you TGV delete, it would be smart to use those signals! I see where you're going!

You can use 1 TGV input even if you don't delete them. That's what I'm doing now. You just duplicate one TGV to drive both, then use the spare one for whatever signal you want to input.

The microcontroller is just so that you can get the digital LED only display, right?

Yup. It takes the analog 0-5v signal converts it to AFR value, then writes the value over the digital serial port to the display.

Just found the UEGO on Amazon for $153 with free prime shipping. Probably going to go that route

Have you considered spending $153 on hookers and blow as you DO NOT need a wideband on your car at all? My 250,000 mile trouble free Subaru has not seen the need for one since April 2003.

I have a feeling 153 may not get me very much blow and probably an undesirable hooker. Hahaha
