Tach jumping around at idle.

Hi i am running a MS2 Version 3.0 and am using the edis-4 set up. I built the tach output circuit as instructed and when at idle the tach jumps. When im off idle it seems to work just fine, it only acts up at idle. Any suggestions. Do i just need to add a capacitor into the circuit somewhere, or will that just degrade my signal. Any help is appreciated. This is on a 92 Toyota Camry if that helps and i am sending the signal via the factory wires that lead to the control module.

draco12369,

Does the tach also jump around in MegaTune?

No in MegaTune the RPM is pretty stable.
