Little square 112 pin ECU used both on Indian bikes as in https://www.indianmotorcycle.com/ and Indian cars as in https://www.marutisuzuki.com/ with Polaris, UAZ and VAZ in between.

Maybe one day we should make an open source design simply because of how widely this platform is used, maybe one day.

Slingshot action

schematics is more or less just the pinout with IGBT https://github.com/rusefi/rusefi-hardware/blob/main/breakout-boards/adapter-board-me17-112-B-schematic.pdf

I am hesitant to release gerbers for the adapter since I do not want too many people to start using the adapter instead of pushing for a proper me17 hellen. My plan is to revisit the plan in a month from now depending on how much me17 progress is made.

What is a "proper me17 hellen"? What it means?

it means "single PCB plug and play ECU which uses original vehicle connector and usually fits inside original case"

like https://github.com/rusefi/rusefi/wiki/Hellen-154-Hyundai or https://github.com/rusefi/rusefi/wiki/Hellen-88-BMW

Too thin wire for ground return?

Smoke was probably my fault - I've unhooked the superseal plug with power GND while vehicle was on.

Anyway wire looks to thin for power GND for 4 ingition transistors.

we now have an open source ECU compatible with that pinout https://github.com/rusefi/hellen-112-17

Waiting for harness components to actually test this further

Hellen compatibe with Bosch 17.9.7 and siblings
