Hey guys
I've been doing testing on this and I have to say, I am impressed by how well it works! We're doing more dev testing, and here are a few videos!
I'll keep posting on here when new progress is made!

Next step we need some CAN Lua for A/C logic
just a skeleton for now:
Code: Select all
-- listen to CAN ID 0x500
canRxAdd(0x500)
-- todo: add payload logic
packet546 = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06 }
function onCanRx(bus, id, dlc, data)
id11 = id % 2048
print('got CAN id=' .. id .. ' dlc=' .. dlc)
-- todo: add filtering logic if needed
rpm = getSensor("RPM")
-- handle nil RPM, todo: change firmware to avoid nil RPM
rpm = (rpm == nil and 0 or rpm)
if rpm > 800 then
-- at the moment we simply
txCan(1, 0x546, 0, packet546)
end
end
function onTick()
end

Norman, spoke to Andrey. Need to give you heads up.
ECU will need to output AC Pressure, Coolant temp, and current AC status.
I'll attach wiring diagram for you below.
ECU on this car also reads ac pressure sensor.
Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA]

I'm looking to produce some boards for my clients.
Does it still support cruise control?
Anything we should know that isn't supported by that?

Question on grounds magic.
This Hellen 154 Hyundai
https://rusefi.com/docs/pinouts/hellen/hellen154hyundai/ https://github.com/rusefi/hellen154hyundai/blob/main/boards/hellen154hyundai-c.fab/board/hellen154hyundai-c-schematic.pdf is your typical design with on-board IGBT and three power GND pins on the header/in the harness.
Would it be better, worse or no difference to have a designated Power GND pin/wire just for the on-board IGBT for the on-board IGBT and on-board everything else grounds to meet on car body, or actually share a huge GND on the PCB?

Actually
https://github.com/andreika-git/hellen81 is an example of exactly that - explicit IGN_GND pin.

I have a customer interested and I'm looking to make a small batch.
I was looking at the revc file and rev d. Revd is autogenerated version. Should I take the time to review and updates the bom or the changes between c and d doesnt worth it?

rev D changes a lot internally and there is no firmware for rev D. As of today rev C is a safer bet.
