Is there a chance to make a universal f0+f1 firmware image? Just an early chip detection (using an external mcu pin tired to gnd or something?) and two branches of code to configure the hardware.

Re: Bricking
I've noticed yet another way to brick my board (hellen81): if I set wrong SPI settings for the SD-card (wrong SPI number and pins), then something happens to the USB config inside the firmware (possibly somehow related to the mass-storage driver part?), and TunerStudio cannot connect to the USB-COM ...

Re: Hellen 128 Mercedes
The primary ignition coil resistance may vary greatly: from 0.2 to 3 ohms. Usually it's about 2 ohms, i.e. the average current is 7A. The dwell duration in running mode is usually 2-4 ms, and for cranking it may be increased up to 10 ms or more.

Idle is way higher than expected. According to the log, your TPS position is 2.6% which is higher than 2% threshold, that's why the auto-idle is disabled and the IAC valve is stuck at 89.95%. Even the REO says it's running, not idling :roll: Tach no longer works I am confused. Maybe because you cha...

In order to simplify the LSU sensor wiring, we used a board-to-wire connector on the board: image.png This is a XH series connector (XH-8A) with 2.50mm pitch and 3A current rated pins. We use double pins for the heater output and ground. The best part is that JLCPCB...

Hellen81 PnP for 81-pin M7.9.7/ME7.9.7/ME7.8.8/Yanvar7.2/Micas10.3
Hellen81 is an ultracompact and cheap yet full-functional 8-Cylinder ECU board. The board is compatible with some 81-pin ECUs: Bosch M7.9.7; Bosch ME7.9.7; Bosch ME7.8.8; Yanvar7.2 (Январь 7.2) Micas10.3 (Микас 10.3). The board is NOT compatible with 121-pin VAG ME7.x vehicles!

Most of the MS2 derivatives use just the same BIPs as the Prometheus does and you can just solder B to C and use the signal, but a buffer of driver IC would be the most elegant method I think. Yes, you can solder jumper wires instead of BIPs. I've used Prometheus with logic-level COPs just fine: !l...
