Does FreeEMS support communicating through a standard automotive ODB-II port ? I believe it's just a serial port running at a range of possible baud rates...? Does FreeEMS support logging faults or most/all data to some type of network connection to a tablet or pc ? I guess rsyslog or something of t...

Good idea Fred, to find out which pump is being used by the smaller bike manufacturers. The one I mentioned was for use on a Ducati 1100, two or four cylinder not sure. The current draw numbers you mention, 2 Amps or so, that's totally doable on this bike Crossing off the eco company's products from...

Thanks Fred. Your estimate adds up to about 17.5 Amps at 12V electrical power needed just for the EFI system. 1. ECU 1 ampere, or less, max 2 or less, but likely in the hundreds of mA region. 2. Fuel pump, 10A+ typically, some up to 50A, but smaller ones should draw less. Still need high pressure, t...

1) Battery capacity and/or charging capacity to run the system sustainably 2) EFI fuel pump physically small enough and electrically efficient/lean enough to supply the engine and conform with 1) 3) Injectors with sufficiently small flow to not make tuning near-impossible 4) Instrumenting your engi...

I have one of the very popular carburetor based 50cc GY6 Chinese scooter, made in 2012, itself a clone of the wildly successful Japanese Honda Elite GY6 engine from the early 1980s. It's hard starting in especially in colder weather. It usually stalls out the first 5 or 10 starts before it'll stay r...
