No speedo

Tedmeister · 12-11-2021, 05:42 AM

I had the car tuned with uprev last Saturday. It did well on the dyno, 330hp
with minor mods, but the speedo no longer operates. I had the same issue
in February when it was dynoed, with no tune, just to get a baseline hp number.
I don't remember how it started working again. This time the tuner said to just drive it and it will come back on. I've driven the car about six times and gone at least 20 mi. It has thrown code P0500 Permanent. I'm running 275 35 18 square.

Well when that happened to me I went off at the track and the speed sensor got confused. I just unplugged the battery and waited a couple min and plugged it back and it worked fine.

I disconnected the battery for 30 min., with no effect. I ordered the uprev cable and this afternoon, with the help of the tuner will try to get to the bottom of it.
