Any Toyota Tacoma Tuners out there had this issue? Not matter what info I enter in speedo calibration the speedo reads slow... Is there something I am missing??
i believe with hp tuners the speedo calibration is for automatic trans shift points only.Originally Posted by desertfab racing
I had the same problem. the trans output channel is correct. i contacted HP on a ticket and they verified that the speedo is taken using the wheel sensors(ABS Trac con) and not the engine management. i eventually just took the bezel off the dash gauges removed the needle and placed it 3mph slower(reindexed)it. using GPS it is accurate at 60 MPH that's all I need for the purpose of slowing when police cruisers
are passed.
Oddballs, on all cars the speedometer shows about 5% higher than the actual speed
If the Toyota tuning is like the GM tuning you want see any change unless you flat both the TCM and ECM.
