Re: The ultimate ECU & TCU & PDM & AWD project !

F7 flash drama can be solved by cheap spi/qspi flash chip.

I strongly suggest using specialized automotive chips for output stages. With diagnostic and protections. Instead of discret smart mosfet.

Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

I don't have a recent picture, but both sensors are placed just after the Y junction where the 3 exhaust pipes meet. The straight section just before the next bent. Could it be possible that one bank of cilinders is running so much richer/leaner? I don't really have synced all the cilinders yet. Fi...

Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

I have disconnected the CAN wires and the module started heating all by itself, and AFR was al good. With a engine running I have two AFR and they are a bit apart, so need to fix that, but channel 1 has a big delta in the readings (about 0.1) compared to channel 0 (about 0.09). Via the can bus, is ...

Re: ECU accuracy

Secondly, for all these sensors it is necessary to set their parameters at several points. Now the IAT and engine CLT set by 2 or 3 points. Seriously? There are not only linear sensors, there are even sensors with a polynomial or logarithmic curve. Through 3 points they will show garbage. https://g...
