I’ve been playing about with the ECU after getting the V8 program working, and have reset my fuel trims. It’s now reading around -10%; do these 190 ECUs always read rich or should it be a bit better?
Ive tried unsuccessfully to connect using an elm327 wifi and a bluetooth obd.
How did you connect up?
Depending on vendor they sometimes disable the ODB2 port .
Usually the ‘ELM327’ aren’t really ELM chips, but something newer that can support the chipsets, but don’t actaully work. I was using this:ELM327 OBDII / EOBD Car Scan Tool diagnostics interface (Wi-Fi), but Apple have done something that means that newer iOS versions don’t work with it anymore, although my older iPad works just fine. I ended buying an old ELM323 (the EFI supports ELM323 or 327) but you’ll need a decent quality serial to USB convertor, as the cheaper ones don’t always work (the StarTech.com with the FTDI from Amazon works just fine though).
