A90 Supra engines and parts diagrams (all) revealed!

CAN protocol is a very simple protocol, you just need 2 wires (CAN high and CAN low) to transmit data...that's why the auto industry uses it. For example, in my line of work, we primarily work with automation for high voltage equipment....so CAN BUS wouldn't be as efficient as say ModBus over TCP or DNP for electrical interfaces (HMI's) or controllers that need more data points transmitted. However, this still doesn't make interfacing CAN with older ECU's or integrating emulators with CAN a reliable or affordable solution. There are a few standalone ECU's that can integrate with CAN, but they are still ways away from being 100%.

Btw, Pure Automotive still has a check engine light that appears with their solution no? The 86 works, but will it pass emissions when they connect the cord???

You're right, they're not at 100%. That's why I said almost perfect. You have to sometime cycle through ignition to get it working. But for a pretty cheap translator it's absolutely worth it.

Regarding the CEL, I doubt it shows. It is controlled directly through CAN BUS and if my guy figured it out they have as well.

We did another 3UR swap in an FJ Cruiser where the old 1GR ECU used mostly analog signals for tach and temp. Using the same translator hooked up to an analog module, the CAN BUS was converted to analog and everything works as it should.

Info on this please!! I have an FJ cruiser and wouldn't mind doing this down the road if my engine ever decides to blow up on me

New engine codename B58C30O1 for J29 Toyota Supra 40i from wikipedia
https://en.wikipedia.org/wiki/BMW_B58

Very strange why replace B by C.
It's a fuel type code
B -> gasoline
C -> Ethanol?

Found this but it's definitely not right. My guess is Flex-fuel but I'm not familiar with BMW if the "B" category also includes Flex-fuel in previous engines.

Why not? It's only fair for a SUPRA to have a 2JZ. I know i'm not the only one planning this either.

As an owner of a 2J Supra (and two other JZ-powered cars, look at my sig)....that seems really silly to me.

I'm very much looking forward to the B58 engine. The iron-block 2JZ is a god damn boat anchor. I'm sure the compact and lighter aluminum B58 has major impacts on handling dynamics, turn-in, etc....and as already stated, it's proving to be a pretty stout and tunable power monster for those that wanna chase big RWHP numbers.

I find this number strange B58C30O1.
I would think more B58B30O2 if it's same engine than X5 and Toyota has update some parts.

I finally find B58B30C

Ahh, the BMW has the "Upper" designation, but the C makes absolutely no sense.... Custom?

Bmw have already used c for the B57D30C but for a quadruple turbo but the Supra has a single turbo

The 'C' is quite confusing when looking at the B57 example because it is also referenced as "S" and "T0P" in various documentation. "S" referring to Super and, "TO" meaning "Top-new development" while "P" is a mystery

EDIT:
Here it references "C" and "S"
Here it references the G11 having the "T0P"

The Chinese market 120i has B48A20C name.

Another confirmation of B58B30C code from
http://www.realoem.com/bmw/enUS/showparts?id=DB43-USA---J29-BMW-Supra 40i&diagId=11_7844

But it’s same engine code for x5 g05 40i missing the reversion number I think some parts change between x5 and Supra
