Wideband CAN interface
 

Haven't seen it really discussed on here so I'm probably one of a few actually running this setup.

I picked this up from MSLabs a few months ago. Just got around to installing it with my new ms3 setup. This is basically a credit card sized board that has 4 wires you run to your db37. Power, ground, CAN H and CAN L. You then run the included serial cable to the serial out on your wideband controller. In my case an innovative LC-2. No need to worry about offset or calibration, just enable it in your CAN settings and it's dead on. It's seriously easier to setup than a non CAN interface.

Unfortunately I didn't get a picture of it before installiation under the passenger side airbag. I'll try to snap one this weekend when I get in there to clean up some wiring.

Interesting. Where did you get your CAN module?

Reverant (MSLabs).

Well, that makes sense given you're posting in the MS Labs forum!

Any details? Is it similar to the GPIO?

It is not like the GPIO.

This is a really small board (80x55mm) that is preconfigured for the job.

It doesn't require any configuration on your part.

It's sole purpose is to connect to one of the widebands that have a digital output (Innovate LC-1/LC-2/MTX-L, AEM UEGO, AEM Inline UEGO, Zeitronix) and feed the digital signal from the wideband to the MS2/MS3 through CAN Bus.

This makes sure that whatever your wideband is reporting (and whatever you are seeing on the wideband's physical gauge/display) matches with what the ECU is seeing. Ie zero offsets.

As an added bonus, this method will also refresh faster on the AEM and on the Zeitronix, which have highly filtered outputs (especially so on the Zeitronix) and will also remove random noise from the AFR signal.

Finally, if communication is lost with the wideband or if there is a reported failure from the wideband, the module will report back "14.7" so as not to trigger any more EGO corrections and make it lean out or go stupid rich.

Does this work with the MS2e? How about a price?

Yes, it does work with the Enhanced MS2, you may need a small firmware update though.

Pricing is not yet determined when not buying with an ECU, I may need to do a group buy on these as shipping and customs fees will quickly kill it otherwise.

I'd be in for one...

No idea how big this device is but could one or more not piggyback with shipped ECUs coming over? I'd definitely contribute to any additional shipping cost the ECU would incur.

Yes it can, obviously that would mean you need to wait until the next batch ships.

Foot print is approximately the size of a credit card. ~.75" in height

So if I'm not running any AFR gauge, can I still benefit from this WB02 CAN module? Or am I better off wiring up my LC-2 in typical fashion?

i'm in for one too with you EGT board as well!

Using the CAN board will always yield better results than wiring the wideband through the analog input.

Its not uncommon to sit at 14.7 for 10+ seconds while idling with the CAN board. Closed loop works really, REALLY well with 0 noise on the AFR signal.

Got mine from Reverent the other day for my Innovate LC-2. Label added by me to aid identification in the future. Like ryanr said, you wire power and ground to the WBO2 controller as usual and connect the DB37 to the MS3 and the serial connector to the WBO2 controller digital out via the Innovate supplied serial cable. I look forward to getting this all hooked up!

Interested in group buy.

Reverant. Can board be put inside MS3-Basic along with a serial port on the end face?

Hey look at that, you have 2 endcaps on the module:party:

A group buy might shave $5 off the price, but no more.

The board is not designed to go inside an actual MS2/MS3, whether a generic do-it-yourself unit, one of our units or a competitor's unit. There are no provisions on the CAN board for mounting.

OK. Will PM for pricing.

Email sent! If this works with my MS3-Basic then DO WANT. I don't like the MTX-L gauge controller I'm running now, so this will be a perfect addition when I switch over to the LC-2 I've been eyeballing. I'd much rather use the digital output rather than the analog I'm running now.

Nice to see MSLabs bringing more sexy goodies to market, keep up the good work!

It does work.

I received your email but can't reply until I restore my system (controller firmware or driver bug caused my raid5 array on my system to go belly up)
