Re: Limp Home and Engine Protection

what's the usual way of checking engine temperature? from the coolant temperature sensor? what if there's a crack in the rad, and all the coolant has run away? will the sensor still provide valid values? i mean to say, for the peace of mind coolant level sensor is a must.

Re: Full JLC PCB

you mean to say pb5 and pb6 of stm32f405rg56 are not 5v tolerant? according to the datasheet, they are! or they are only 5v tolerant as general GPIO, but not for CAN purpose? is it a 2 layer or a 4-layer board? you can still use it: replace the can transceiver with 3.3v-powered one, cut the 5V suppl...

Re: 3D printing ECU case - cost?

I'd suggest that instead of investing in a 3D printer, you invest in a milling machine :D
What was rationale behind the 3d-printed case vs aluminum one?

Re: FrankenFerrari - V12 Ferrari 308

In my case, the needle in the cluster was driven by voltage from 0V (full tank) to somewhat 12V (empty), but it's electronic circuit there, not just a winding. In your case (old-style dashboard) this winding is driven by current, so may be you don't need it that difficult, and simple pwm will do.
