Yanvar January 7.2 OEM ECU from Russia

Post by AndreyB »

Yanvar January 7.2 (Январь 7.2) is quite an interesting OEM 81 pin ECU for Lada and other Russian vehicles like https://en.wikipedia.org/wiki/Lada_Samara#Samara_2

A couple of things are cool about this ECU. First of all, this ECU is pin compatible with Bosch M7.9.7 which was used on some Asian cars around 2000, for example Daewoo Spectra, Hyundai Elantra or https://rusefi.com/wiki/index.php?title=Vehicle:Hyundai_Accent_2001 - these cars were available in the US.

Secondly, there are a lot of cars in Russia using this ECU. They definitely have tuning options and even custom third party firmware but I believe nothing free and open source. I believe it would be cool to have a rusEfi board with this pinout as an attempt to get more software developers participating in rusEfi.

See schematic at https://github.com/rusefi/rusefi_documentation/tree/master/oem_docs/January_7.2/schematic

I believe there is a huge chance that https://github.com/andreika-git/deucalion by @ would end up being pin-compatible with Yanvar January 7.2 - more about that board at https://rusefi.slack.com/messages/CF6JUMK3R/details/

And the 81 pin connector is just a larger part of the 121 connector https://rusefi.com/wiki/index.php?title=Hardware:OEM_121_pin_connectors I guess the "Asian" version of it.

Apparently there were quite a few hardware revisions - see schematic at https://github.com/rusefi/rusefi_documentation/tree/master/oem_docs/January_7.2/schematic
