Well, https://github.com/rusefi/proteus-Honda-K-125-adapter is a mild disaster: Honda K has two different pinouts, "SUV pinout/late models" pinout
on the current adapter, and the early car adapter which everyone wants

For now I've quickly soldered a Proteus adapter using https://www.ebay.com/itm/334141525131 and the car runs! Next step is VVT configuration cleanup, still confused about two cam inputs - which one is VVT, which one is intake, which one is what. But with a recording of all three signals it should not be a big deal.

Note the Nissan Sentra plug wire helping with COP timing light setup

I believe you may need to use the new "cam for sync" option set to NOT zero, since the exhaust cam is the one that has enough information to sync the engine.

[AndreyB]

Haltech says "The Exhaust Cam Sensor is used for the Home input to the ECU." and "Home Tooth Pattern 4+1"

in your logic analyzer snip, the three channels are crank/exhaust/intake

Thank you! Also https://github.com/rusefi/rusefi/issues/4611

Honda-K Hellen is hopefully 45 days away from reality.

OEM 125 header has five sections. Manual cars use only three sections, the other two plugs are used for automatic transmission. We have no chance to control that transmission soon so we have a great chance to use plugs C or D for WBO and aux.

What would be the arguments against using the bigger of two plug C for aux? https://github.com/rusefi/hellen125honda-issues/issues/1

Another question VTC control https://github.com/rusefi/hellen125honda-issues/issues/2

On the white car under rusEFI control power steering does not work.

How on earth is power steering related to ECU you would ask? Well all I know there is a EPS Power Steering Module 39980-S5T-A131-M1

https://www.civicforums.com/forums/21-i-c-e-audio-electrical-upgrades/375997-diy-eps-conversion.html mentions VSS and RPM signals. To be continued.
