EFI TBs and ECU discussion

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Ha!
Fuel pump is connecting to left EJT32L only
Therefore ECU is not interchangeable

Pretty sure someone on this forum tried taking off one of the plastic covers, but it wouldn't budge, I think it is resin filled inside, or glued, the clips at the edge of the plastic covers are only a convenience for assembly, when the resin is cured, they are stuck on.

Of course I might be wrong tho. (Often am. :D )


Of course inside is going to be tiny TINY SMD (Surface Mount Device) components, which you can't do anything with unless you are an expert at that sort of thing and have the relevant tools. (Can't just use your $20 soldering iron from Tandy.)

This hole seems to connect with ECU?
Darrell told me about the tiny hole inside TB

It is able to sense manifold pressure, so probably what that is for.

Appendix: thanks for the connector photos!

I really like how they make an EFI that behaves like a carbed bike but you can’t adjust lol!

I've been milling over this very problem recently and I have some thoughts. Gobi, going to pm some interesting abstract concepts to you after I get home. I'm guessing that Ural is never going to release a customer tool for dealing with the computer, and it's a shame because now I'm going to have to give my money to someone other than Ural to fix the problem.
