more VSS issues

Now that I have the new file for the tweecer and data logging works I decided to check out the VSS reading. between 0-25mph there is no reading displaying in calcon. between 25-35 the numbers are wacky. 35+ it reads steady and accurately to my speedo and GPS.

new sensor, new wiring from sensor, new PCM any thoughts? These items were replaced trying to figure out why the low speed shift points are messed up.

and to refresh everyones memory:

using a volt meter to check voltage from the vss @ the firewall just before the ECU plug gives a proper output at all speeds, IE: a steady increas in wheel speed = a steady increase in the voltage reading

the pcm has been swapped, no effect

the turbine shaft speed sensor has been swapped, no effect

the car has been returned to "stock" and the tweecer removed, no effect

grounding wires were strung from the battery negative to various points on the engine, no effect

I'm sure you guys checked the ecu? Sounds like you guys might have a bad computer! Get a known good one, and see if you have the same problem?

I replaced the ECU and have the exact same problem with the new one.

Neutral switch?
