Konrad Posted February 3, 2016 Share Posted February 3, 2016 So here it is a bit unusual I own facelift Supra and I've done 1JZ conversion to it. After some time I discovered that speedo is not showing proper speed and I get odo light flashing. I assumed that it is dodgy converter, so got another another, replaced it and... speedo still showing wrong speed. Now - there is no odo wire in facelift wiring loom behind dash as odo is mechanical. Should I still extend 1jz ECU odo wire to in signal and it will solve problem or you think it is something else? Quote Link to comment Share on other sites More sharing options...
Konrad Posted February 5, 2016 Author Share Posted February 5, 2016 Ok, speed problem was simply needle out of correct postion, pulled it out and put it back when doing 60mph according to GPS speedo and all is fine now + - 1mph. OD Off light still flashing tho... Quote Link to comment Share on other sites More sharing options...
