Hi gyus.

I have AEM AFR Failsafe (30-4900) which doesn't have serial rs232 output however there are analog +5V output which provides the AFR level signal. I'm curious about getting this analog signal using a 2.5mm Stereo Jack and passing it to the RomRaider.

Is there any way to log using romraider that voltage (or calculated value based on that voltage) from tactrix 2.5mm tip (OEM12 pin)?

cant help you logging the 2.5mm jack - but you could take that 0-5v input and log it from a rear o2 input

Good luck and may the logs be ever in your favour!

i've found that for my forester 2007 ot should be a "B4" wire at B135 socket/plug

is that looks true?

what is the best place to wire? directly at ecu side of the harness under passanger's carpet? (my aem afr output wire came from gauge mounted to dash)
