I was playing with the same idea but for the Mazda ECU - traced a lot of wires etc. The killer in case of rusEfi is the fact that our stm32f4 chip is 3.3 volts, not 5v as it should be in an ideal world. It's a loooooong story, but for all the pros of stm32f* we have to pay with the 3.3<>5v bridging which would make an add-on board a bit larger then you want.
It could be done, but with limited resources I just wanted to get stuff running so ended up with own universal ECU board.
I wanted to start a project but did not know where to even start with the k-series ecu, It can't be much harder then adding external eprom for maps and what not but with no online info. Like i said i did not know where to start.Statistics: Posted by efihacker — Wed Sep 09, 2015 2:12 am
