Not sure if it's relevant here but this reminds me of when I worked on an MK5 Astra conversion a few years ago and the electric Power Steering wouldn’t work without the engine running.Jack Bauer wrote: ↑Tue Jul 06, 2021 10:18 am So in the E36 builds that I have done the brake / ABS works without any Engine/gearbox input. However I did have a 2000 E36 compact briefly that seemed to be a bit of E36 and E46 mixed together so it may need some dme can to keep everything happy. If so its well hacked and you can copy whats on the E46 class from the vcu repo.
Superb! Nice one Tom! Taking away the rusty brakes, it's so smooth. Great feeling getting that first drive in. Keep it lit! Itching to get mine back on the road. Life has taken over again and the BMS is all that is holding me up but just need a full day to sort it.bobby_come_lately wrote: ↑Mon Jul 26, 2021 4:12 pm
Decided not to edit it in the end. The 'clip' you can hear my wife talking about is a wheel chock I forgot to move! The other scraping is just rusty brake discs and some slightly bent tinware.
That's absolutely it but in this case it's a canbus input it needs. I have a spare teensy coded up with a pared down version of Damien's VCU code that just spams the system with the relevant values for now. Later I will link it in to inputs from the inverter so that I can get tacho output etc.Mouse wrote: ↑Wed Jul 28, 2021 2:59 pmNot sure if it's relevant here but this reminds me of when I worked on an MK5 Astra conversion a few years ago and the electric Power Steering wouldn’t work without the engine running.Jack Bauer wrote: ↑Tue Jul 06, 2021 10:18 am So in the E36 builds that I have done the brake / ABS works without any Engine/gearbox input.

I spoofed the original engine RPM by mounting the original camshaft pickup sensor on the motor shaft with a magnet which got the dash to work but showing twice the RPM. Then using the power of Arduino detected when the motor was stopped or below a certain RPM and produced a 'tickover' output to fool the car system + power steering the engine was running. There was something about having to 'start' the engine by providing a higher RPM for a few seconds when first turning the ignition on. The Arduino also provided a divide by 2 to get the car dash to display the correct RPM.
Cheers Fiachra! MOT booked in for tomorrow morning. It's going to fail but hoping not on too much.Cookie6000 wrote: ↑Wed Jul 28, 2021 9:13 pmSuperb! Nice one Tom!

Good to know. I really will have to learn some CAN bus if I'm going to continue playing with this sort of thing.bobby_come_lately wrote: ↑Thu Jul 29, 2021 5:57 am That's absolutely it but in this case it's a canbus input it needs.

It's pretty crucial it turns out. Satisfying when it works, frustrating as hell when it doesn't.Mouse wrote: ↑Sat Jul 31, 2021 7:59 amGood to know.

If you combine multiple functions into one cooling system i recommend low radiator with integral tank. I got one of those from old Fiat Uno or Panda cars, year 88... Maybe some other small cars have such...
