I got a used autocal so I can log my rail pressure when I pull next week. I have the software loaded to my laptop. Transfer the pid (e54). To the autocal. I have desired and fuel rail pressure ( frp_c ) selected among others. I made a short log to check. Everything thing logged except actual rail pressure. That's really all I care to log so I need help to figure out what I'm doing wrong. When i started the log I got an unknown pid message but I read that could be from too many selected
Thanks I did some searching but didn't find anything useful
