Accuracy is not so bad by the way.

Just a funny picture of my test bench.
Too different eras and markets...

Capture! Dump! Take a short of oscilloscope! Write down a partnumber! Pleeeasaaseee.

How it will be handled on software side .??

Metal enclosure for a board with bluetooth?

Optional BT. For BT fans there is plastic case. See first post in this thread.

New hw is just arrived.

I had disconnections when charger and ecu were connected at the same time.
Laptop has dead battery so I start using cheap USB isolator (ADUM3160 based) from Aliexpress. Now I can have both charger and ECU connected to laptop, and get not disconnection when cranking.

PC/laptop connection? Laptop charger? Try running without charger (with only ECU connected over USB).

https://github.com/mestrode/IBS-Sensor-Library but not compatible with these two sensors that I got from junkyard.

which code? it's just raw data..
btw, googled for that BMW battery wire and got this:
"Плюсовой провод аккумуляторной батареи БМВ, Клемма аккумулятора BMW с пиропатроном" %-)))

LIN bus driver code.
I have only minus battery wire. Hope it will not explode.

Hey, has the Rev1 PCB been tested yet? I'm considering ordering 2 assembled from JLC to have a play with in the garage. REF3033 is OOS everywhere at the moment, what do we think of ZRC330F02TA as an alternative. JLC have it in stock currently. Cheers. Not yet. It is on the (two) ways to me. Hope to...

Battery voltage drops down to 8.53V (actually seems even lower) during cranking. This cause controller to switch to SensorNoHeatSupply state and after battery voltage rises above 9.5 - start heating from the beginning. https://github.com/dron0gus/wideband/blob/master/firmware/wideband_config.h#L55 S...

Do you connect laptop to the MRE's internal USB connector or through main connector?
Do you have AC charger connected to your laptop? If yes - can you try without charger?
Please show us you MRE to car chassis/body connection. Please show us your battery to chassis connection.

Why would you give the user an option if there's only one pin that can possibly work?

Because you are the first real user of SENT! Congratulations! And thank you for testing!

What connector pin are you using to supply MRE?
MRE measures Vbat using pin 1. But can be powered by pin 1 or pin 5. Please check this.

Main connector pinout added to silkscreen.

Rev1 was just released. https://github.com/rusefi/rusefi-hardware/tree/main/lambda-x2/export/rev1 Any feedback is welcomed. Short changelog is: * Switch to 64 pin STM32/GD32 * Add 8MHz HSE oscillator (better clock stability for CAN over wide temperature range) * Use DAC (instead of PWM) outputs for ...

@Dron_Gus would you mind to share any test results with this board?

No tests are started so far...

The breakdown voltage for this mosfet is 100V minimum. The datasheet doesn't specify nominal and max voltage so this could might as well reach 200V under some operating conditions. I wouldn't want voltage spikes of this magnitude coming into my ECU. Also I don't think it's wise to use a mosfet in a...

Lambda-x2 is currently in state of designing rev1. And debugging SW on rev0. It is compatible with same SW as all other widebands based on mck1117's initial design. See https://github.com/mck1117/wideband/tree/master/firmware/boards . f1_dual = lambda-x2 SW development for lambda-x2 happens here htt...

This circuit also has no clamping mechanism whatsoever.

Only injector outputs have no clamping circuit. To speed up injector closing. MOSFET reversible breakdown is used to clamp high voltage spikes.
All other outputs have diodes to +12V.

ETB IC powered from this pin and can consume more than 5A
Also there is overvoltage protection for >33V on this pin.

did you try out the trick circuit to generate cleaner "aux analog output" pwm?

(https://www.edn.com/cancel-pwm-dac-ripple-with-analog-subtraction/)
Not yet. Switched to S105 ECU.
Hope to find some time during holidays to finish rev1.

In the "Nernst Sense" section of the circuit, instead of "LSU_Vm" consider a voltage divider with a voltage set to virtual ground + 0.45 volts. That way you are not amplifying the 0.45v common mode voltage and you can greatly increase the amplification. Using "virtual groun...
