Speedo Output
Posted: Sun Oct 25, 2015 8:40 am
Lance,
I need some help with the Speedo Output (spare port 0). I am running a 4L60e gearbox with Mshift code 5101ii. I need the speed to be in km/hr. I have set the SI Lengths to be activated. In TunerStudio MS 2.6.19 the speed is shown in km/hr and the indicated mshift speed appears to be correct. I have checked this with GPS speed in TunerStudio and what mshift is indicating is very close to GPS speed and the speed gauge works smoothly with no sudden surging or dropping etc. So I assume that the VSS settings are o.k for mshift. The speedo output is working, although it appears to be indicating the speed in mph rather than km/hr. By this I mean that when I am travelling at 60 km/hr the speedo indicates just under 40 and at 100 km/hr it shows just over 60. The OEM computer sent 6250 pulses per km to the speedo and this is what I have set in the spare port 0 output settings. I have also tried 0,10,15,25,40,50,75,85,90,95 and 99 for the speedo output duty cycle %. These numbers did not appear to have real effect on the speed indicated by the vehicle speedo. Can you see anything that I have done wrong? Any help would be appreciated.
Thanks
