Holset HE351VE standalone controller (arduino based)

I'm starting a new project controlling a Holset HE351VE VGT turbo. I'm building it based on Arduino with the following hardware properties:
- CAN BUS communications to control the veins
- MAX9926 to read turbo RPM's and engine RPM's (from any magnetic sensor pulley, camshaft sensor, etc..)
- two map sensors: one for turbo boost and another for checking manifold pressure
- read of TPS sensor

about software, for the moment I'm going to use a simple 3D table RPM vs TPS, logging RPM and MAP.
In future I would like to have a good PID system.


current status: CAN communications working and controlling successfully the turbo VGT motor. MAX9926 near working.

I don't have installed the map sensors yet.

Now software is just a few test methods.. I will release it in github when it's usable and not shit looking.

Any suggestions?

Suggestion: Send me one of these turbos for my 740, ASAP. :-D

How much did it cost you landed in Spain? Can't have been cheap! :-o

Peter did some work on controlling these with FreeEMS a while back. I'm keen to have integrated support for this thing, as it's what I want to use on the Volvo once I build the engine, and I don't want two boxes on the car controlling the engine hardware.

Yes it was not cheap.. Something around 650 eur with customs fee + shipping from canada


I think also if I've a good working freeems is better to have control on it.. But for first stage i prefer to have it standalone as i've many cars and ecus.

Fair enough :-) Keep us posted!
