The CAN module is not related to the OEM analog O2 sensor (which is also not used at all with the Basic MS3), so I don't understand the question here.

I worded that horribly and asked the wrong question. What I wanted to ask is "what input does the analog EGO2 input show up on?" I RTFM'd and answered my own question. I have a track day next weekend and dyno time scheduled so I need some kind of O2 signal in case I my UEGO's digital out is broke.

I have a few buddies locally that also have UEGOs, I'm going to swap controllers with one of them and see if that fixes my issue.

I recently purchased and installed one of these modules along with an MS3 Basic from Reverant. The MS3 is working great so far (hasn't left the garage yet though) but the CAN module is not. For the benefit of others I thought I would post my issue and (hopefully) resolution here. I have sent the following message to Rev:

"...I am having some trouble getting the CAN WBO2 working though. In the mean time I set the EGO port back to "Normal EGO" and I am using the analogue output on my AEM UEGO. There was about a 0.4 AFR offset between the gauge and tuner studio, so I compensated with a custom calibration. What do I need to do to get the CAN module working? I verified that I am getting a proper serial data stream from the AEM by plugging it directly into my laptop with a serial adapter and running hyperterminal, so I know it is wired correctly - unless the CAN module requires different wiring than specified in the AEM manual? (Pin 2 for data and Pin 5 for ground, if I recall?)."

Anyone else have a similar issue? I assume it's probably just a setting in Tunerstudio somewhere that I am missing (or don't understand!)

I bought this module to gain some precision but can't get it to work properly...

I enable Can EGO, put CAN EGO for the wideband setting and the value stay at 7.xx in TunerStudio. Analog do work fine. Can I damage something trying to reverse CAN H and CAN L ?

I bought it from CowGod could it be set for something else ?

Just want to let you guys know that the INI file was set for AEM, Dimitris handle it and its now perfect.

YOU NEED THAT !!!!!! Awesome no more offset and dyno is better... MOAR

It is awesome, isn't it? :party:

So... how exactly did you get into the INI for the device? :naughty:

<p>Couple questions.</p><p>1. Can this device share the bus with multiple CAN device (MS3, Wideband Can Module, Racecapture datalogger). Is the termination resistor capable of being disabbled by a jumper or something.&nbsp;</p><p>2. Can the wideband input on my MS3basic be repurposed as a spare analog input for a pressure sensor or another analog 0-5V device?&nbsp;</p>

1) Yes
2) No

Nice, I'd been wondering that myself. Some sort of slick programmable CAN display would be neat.

<p>Couple more questions.&nbsp;</p><p>&nbsp;</p><p>1. Trackspeed mentions an optional OBD port option for this. (http://www.trackspeedengineering.com/MSLabs-CAN-Wideband-Module.html)</p><p>Does this mean it combines the wideband CAN functionality with your other OBDII-CAN output module? (https://www.miataturbo.net/ms-labs-miata-accessories-89/obd-ii-data-module-all-ms2-ms3-ecus-79429)</p><p>&nbsp;</p><p>2. If it does, that thread mentions the capability of outputting custom PIDs such as oil pressure and temp read by the spare analog input channels of the MS3. Can these be output and displayed on a&nbsp;ScanGauge II via the OBD2 module and has anyone done something similar?&nbsp;</p><p>&nbsp;</p><p>If it can do this I'm pretty much sold!</p>

Question : Does this Canbus interface work with DIY products such as my ms2pnp, or is it proprietary to MS-Labs?

I see that I have canbus H/L inputs on my option connector, but I am an electronics novice. I would gladly pluck down the money to get rid of infuriating voltage offsets by going this route.

1) OBD-II is standard on all the TrackSpeed modules. All that is missing is the $10 plug (optional) to plug it on ScanGauge.

2) This threads mentions the idea, not the capability. I said it's a good idea, but I haven't implemented it yet.

It works with ALL MS2s and MS3s.

<p></p><p>&nbsp;</p><p>So the available PIDs through the version trackspeed sells with the OBD2 port is:</p><p>&nbsp;</p><p></p><p>&nbsp;</p><p>this was posted over a year ago so I was wondering if any chnages have been made since.&nbsp;</p>

Correct, no other changes since then.

My mate Rev did send me everything! Talking about customer service !

is 1.3.4 the correct INI file for an AEM wideband?

1.3.4 refers to the ECU firmware, not the CAN module.

I'm finally getting around to switching my car over to the CAN WB02 controls this weekend. I just wanted to confirm my wiring before I do.

Parts List:
MS3 Basic for 99
MSLabs Can WB/OB2 Module
AEM Uego

MS3 DB37
Pin 1 (RED) - Wired to AEM UEGO 12v Pwr
Pin 2 (Black/Yellow) - Wired to AEM UEGO Ground (Black)
Pin 4 (Yellow) - Previously WB02 Analog Input - No Longer Used
Pin 8 (White)- Wired to CAN module White
Pin 9 (Black) - Wired to CAN Module Black

Can Module Serial Port
Pin 2 - (Blue) AEM Uego Serial Out

Can Module Pigtails
Red - 12 switched Power
Black - Chassis Ground
White/Black Twisted - MS3 DB37 Pin 8/9

OBD2 Dongle
12v and Gnd are pulled from chassis sources
Pin 4 - Chassis Ground
Pin 5 - Chassis Ground
Pin 16 - Switched 12V
Wired in parallel to the Can Module to the DB37
Pin 6 - Wired to MS3 DB37 Pin 8 (White) CAN H
Pin 14 - Wired to MS3 DB37 Pin 9 (Black) CAN L

AEM Uego (For Confirmation)
Red - MS3 DB37 Pin 1 (Red)
Black - MS3 DB37 Pin 2 (Black/Yellow)
White - Not Used
Blue - CAN Module Pin 2

Future Can Inputs
I should be able to wire all future CAN (7 remaining) items to the Can H and Can L of the db37. I would provide those modules power and ground via external sources but I can T off the Can H and Can L wires on the DB37 in parallel.

Can some one please confirm that i have the wiring straight? Can someone please confirm the 12v and ground wiring I have listed above? Is the WBO2 still supposed to be powered by the MS3 DB37? Thanks in advance.

One more question... does the AEM Uego broadcast on both the analog and the digital output at the same time? Meaning if if leave the white wire (analog out) hooked up to the MS3 db37 while the blue wire (serial out) is hooked up to the can module at the same time... will that give me issues?

I wouldn't mind leaving the analog wiring in place in case I have issues and I need to switch back.

Also... is it important for the Can module and the Wideband to have the same ground?
