Some more progress....
As i am too busy at the moment there is only slow progress for this controller.
The PCBs arrived from the manufacturer and all looks fine so far. I have flashed all of them and until here all looks fine.
Need to solder the CJ125 and the varistor on the PCBs and also need to do more detailed tests.
Stay tuned.

how much for this?

Hello all

I throw in also my version of the wideband controller with cj125 and Arduino nano for LSU 4.9
It is a fresh thing, have not ordered the boards for published version yet. But I am quite confident that it should work as I have the thing working on earlier board and there was only some pin assignment changes. Also the firmware Arduino skech included. Currently calibrates and then displays Lambda value and sensor temperature in real time on LCD and outputs wideband lambda analog signal. Narrowband emulation not implemented at the moment.

Hello all!
I am drawing my own BL49SP board on KiCad and i have few questions about the schematics:

1. "OUT" is 0-5v linear and "PWM" is simulated narrowband but what is the purpose of "IN" connector that go to PC2(ADC2) pin?
2. What state two leds represent, power and heating process?
3. I didnt find AO3400A from Mouser, would this be okay instead?: https://www.mouser.fi/ProductDetail/Inf ... S48UOXVw==

This is what the board looks like at the moment

So looking at the code seems that this need to be grounded when engine is running so code knows to start heating.
i think this replaces need to power controller from FP relay, just configure one of the speeduino outputs to pull "IN" to ground
when RPM > x

I added "IN" and ISP headers, and few routing improvements
just final check for mistakes and then i can order boards
