VSS noise
 

So I just re-wired my EMS4 to include VSS from the 94 stock system. I used a 2.2k pullup resistor off the same 12v line that the 1k ohm tach pullup resistor uses. He's the issue, the AEM numbers were off by like 2 orders of magnitude for speed, would go straight to 255mph as soon as i let out the clutch in 1st. So I reduced them until I could get 10mph on the speedo and 10 on the computer. But if I go to like 20 it'll jump between 10 and 60. This tells me that I have a shit load of consistnat noise at 10, but the noise gets noisier above that. I have filtering and smoothing turned on, smoothing really doesnt seem to make much of a difference. Do I need a low pass filter like the crank and cam signals for this one too? And I'm guessing it should happen between the ecu and the pullup.

Anyone? I'd like to get it working for august 10th when I have my last event this year where I can run launch control. I guess technically if I set my launch control to disable over 8mph I'll be ok.
