Ranger

Is this a Ford Ranger with an electric motor? The ECU uses an STM32, but I don't see injector or ignition controls. Am I reading the schematic wrong? I was thinking it might be a Norway re-badged rusEFI, but I'm not sure what I'm looking at. Could I be looking at an electric truck? https://openinver...

Re: Ford 60 pin EEC-IV connector breakout board

Picture or suggestion of changes? It is likely that the silk screen does not know about the connector numbers. It's hard to see with a blindfold on. I may have this connector around here some where.

Re: Common Rail MC33816 dev board - 4 injectors GDI

The attempt of a boost voltage valid LED on R0.3.2 does not work. It appears the diodes do not drop the voltage enough and U1 gets destroyed. The below circuit was suggested in Slack by mck1117 and was drafted in LTSpice. This circuit or similar should probably be Incorporated in future spins of thi...

Re: CAN support

By far the most poplar is the M12 5 pin, followed by the M12 4 pin. I think you'll find the M8 is small and easily damaged. However if you have a fairly low stress environment, and you have space concerns, the M8 is smaller.

Yes we have several of these PNP boards which could be used as a reference. It would remove a bunch of risk from a new spin.

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection

A very common igniter failure is caused by not gaping your plugs. Over time the gap gets larger and the primary voltage increases until the driver fails. When the igniter breaks then the voltage goes back up and you burns up your primary wingdings. All the car's I've owned have been from the mid 80'...

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection

Don't forget the Waltech WO2 option. It could be made into an integrated option. Some code porting would need to happen. Also would be good to select automotive grade op-amps if reasonably possible.

Re: Uber simple no PC ECU

Looks like this is feasible. See below snap shot of a LTSpice simulation which shows a analog MAF signal being used to vary a fuel pulse from around 1 mS up to about 10mS. The pulse is triggered via a single pulse on the crank. R13 could be a POT which could allow you to adjust rich vs lean ratio. T...

Re: Proteus v12 club

Part of switching + and - is because you'll likely see a slight conduction in one direction vs the other.

Try making those measurements with etb opened and closed. As well try with you meter + on red then again with - on red.

Re: Need help with Frankenso 0.5 board, maybe short circuit or something is missing

Yes the op-amp has a divider. Yours appears to be a correct 2:1 step down. The ADC is limited to something like 3V, so we have to step down the 5V to below 3V.

Re: Need help with Frankenso 0.5 board, maybe short circuit or something is missing

Can you check the op-amp circuits? Those could be broken, or the STM32 could be broken. Do you measure the proper volts on the STM32 pin, then read an incorrect value in TS? Currently My guess is that the op-map is not providing a proper signal to the STM32, so the STM32 then provides a bad signal t...
