OBD2 port on these coaches?

Does my '98 U295 have an OBD2 port?
I'm interested in this app for weighing my coach both with and without the towed vehicle attached.

You should have a Cummins M11 Celect Plus 450 h.p. which is an electronic engine. Look under the dash by the driver's left knee. Bet you are thinking about a BlueFire bluetooth adapter. Here is the page with illustrations of the three possibilities: BlueFire LLC. FAQ

If you are thinking of buying the Bluefire adapter, I would buy something else.  I bought one, and it would never stay connected to any of the different platforms I tried, and the last time I tried it, the engine developed a major shudder and sent a fault code of faulty data going to ECM.  While it was shuddering, I removed the Bluefire adapter and it immediately  went away and has never returned in over the 6,000 miles I have put on since.  I tried to email Bluefire about the problem and never even got a response.

Which blue fire adapter do you have?  Would you be interested in selling it?

I don't doubt your problem. But, I thought an OBD data reader did only just that. Read data. To invoke a shudder there must have been some sort of bluefire internal fault sending spurious electrical or static charges down a wire that shouldn't see such a thing. Where does the bluefire get it's power from? Battery or external 12V or from the port itself.

Perhaps that is the issue on this one then. A bit of bleed over voltage from some crud or internal solder issue in the BF.

This question still looks unanswered.  Quick answer: "no".  The BetterWeigh wants to plug into a standard OBD2 port -- like what's probably in your car.  You don't have one.  You'll likely have a round J1939 Cummins diagnostic port.  Mine was a complete pain to find hidden in the jungle of wires in the kick panel near the driver's left foot.  Easier to find, was a rectangular (OBD2 is trapezoidal) port that is an Allison transmission diagnostic port.

Conceptually, the J1939 and OBD2 do the same thing.  I have no idea if there is any compatibility between the two, but they are physically different connectors.

I use the Scangauge D to monitor gauges and as a trip computer.  The weight/angle/accelerometer stuff needed by BettterWeigh wasn't one of the parameters.  So, even if OBD2 and J1939 were compatible, you may be missing the needed information on the bus.

Roger Engdahl (commercial member) can probably tell you if anything like that shows up on the VMSpc.  If not, you probably don't have the information BetterWeigh needs to operate -- even if you crafted your own with a Raspberry Pi.

I would try the blue fire adapter on another coach to see if the problem is coach or adapter.

I have aScangauge D that came with the coach and it works fine, so it is the adapter.
