[AndreyB]

We are starting a 154 Hellen!

Primary target platform 2010-2014 Genesis Coupe 2.0T

Norman chose to make this board open so https://github.com/rusefi/hellen154hyundai

This board is pretty ready for review.

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?

[AndreyB]

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?

[AndreyB]

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.

[Suprazz]

ok thank you!

2013 and 2014 BK 2.0T models use a wideband sensors but what is it? is it the NTK not LSU 4.9?
