95 Saturn Strange VSS Readings past 50 mph
 

On my 95 Saturn SW2 I seem to get accurate VSS readings up to 50 mph. As I continue to accelerate past 50 the speed on the MPGuino decreases until I reach 59 mpg (on the speedometer) at which point the MPGuino reads 0. So basically once I hit 50 it starts counting backwards until it hits 0 when I am really going 59.

My VSS Pulses is set to 10000.

Can this be caused by too much wire length between my ECM and my MPGuino?

Thanks.

FWIW, I've not heard of this problem in a saturn before.

You could try setting "VSS Delay ms" to 1 and see if that helps.

Yes. That worked. Thanks.
