I think speeduino can't use WB controller based serial com

try to open the box this is what i got, stm32f and bosch 30615 chip
You could feed your controllers serial signal into a coprocessor that converted it to a suitable analog output

how to do that? since this controller have its own software
can you help?

The software for the computer isn't important.
You need to either get hold of the serial protocol from the manufacturer or sniff the protocol using a terminal application.
Then once you know this information then you can make a convertor to translate the serial data into an analog value that speedy can understand.

No, 30615 is CJ125.
I have never seen any aftermarket controller with CJ135
If its a CJ125 variant then it has an analogue output pin, looks like it is connected to C16 which is not fitted. It should be simple enough to take the signal from there.

do you mean C16 next to CJ125 chip? try to route that and found routed to UN (black wire bottom right) also try voltage with multimeter, no significant change

You must transfer this signal, it outputs pump current, so not really usable to feed it directly to an ecu.
I would buy a ready to use controller.

My apologies, I miscounted the pins. Pin 23 should be Ua which is the analogue output from the lambda amplifier, it looks like its connected to C20.
