speedo help
 

Hooked up my dolphin gauges but my speedo off the computer at idle not moving it pegs at 145 mphs and moving at 20 mph 8ve followed the calibration steps hasnt helped have not called dolphin yet do i need to tap off the vss at the transmission?

Re: speedo help
 

What input does it want? The vss is a 4k signal I belive, if the gauges expect different, it won't read properly.

Certain changes can be made in the tune as well if the gauges don't have variable input.

I found this to. Maybe it will help. They have no tech support at all on the website which would bother me if I had their product.:chevy:

Did you look at this one?

They have some explantation on how the pulse signal is made. Its a bit confusing but it looks like which wire is hooked up determies the rating. I see 4,8,16k pulses being possible if I read this right.

Otherwise in the "speedometer" tab in HP Tuners you can alter the VSS output signal to 8 or 16 to match the gauges. Whoever did your tune should be able to make this change in about 28 seconds if his fingers are all broken.
