Remote PDU/IO - Lets Standardize a CAN Table

This will hopefully build on the Wiki page here: https://openinverter.org/wiki/CAN_table_CAN_STD Looking to see if we can standardize towards a CAN Table for a Generic PDU/Remote IO device to build into Zombie The actual end device shouldn't matter too much could be as simple as a bluepill and some ...

MQB & MLB Can log Request - For Zombieverter Comm Additions

Hey All. Wondering if anyone has any sources for a MQB and MLB canlogs. I have the DBC files already, but just looking for some examples to work with to write a Zombieverter CAN plugin for MQB and MLB models. Lots of shared addresses between these two, as well as the Porsche 9x1/Macan. I've got the ...

Re: Mini-VCU Based Stm32-VCU?

Great points to consider all around. I do fear that more forks of hardware will dilute the whole ecosystem, the main purpose was basically to get the board assembly cost down to $100 or so, shrinking the size to make custom boards easier while still using the same circuitry. My ultimate goal is to s...

Mini-VCU Based Stm32-VCU?

Hello All. Inquiring to see if we can set some requirements for a 'Mini' Zombieverter. I'm careful not to fork and crowd this space too much; but I seem to think that there's some space in the Stm32-vcu line for a non-toyota focused VCU, while still maintaining compatibility with the project as a wh...

Re: Fried AEM Electronics VCU 200 Programmable Electric Vehicle Control Unit

I'll bite on this one.

Would you be willing to ship to Canada?
Just a flat rate international box will do.

Re: Show your ECU connectors

Would the best path forward to be to condense the VCU into a footprint that can be just copy-paste into a PCB design for each connector/enclosure type? Ultimately with that many pins available, it's easy enough to add a few SPI IO chips and extend the IO to whatever space isn't used by the base VCU ...

Re: Porsche 981 Cayman S (2014)

I'm not too confident that the 5QE modules are flexray only, as it seems they're used in the Mk7 and it appears that they're still using powertrain CAN connected on Terminals 16(CAN-L) & 25 (CAN-H) If you notice the Q7 wiring terminations in my previous post these terminals are unused, so I'm li...

Another positive point is that it'll still identify all modules with the ECU/TCU missing. The only issue is the automatic mod...
