Hello....

I have a signal issues with my MS3X and sending TACHO to Glowshift Digital tach.
https://www.glowshiftdirect.com/blac...h-shift-light/

Motor: BP4W with OEM coil pack

Tach has 3 wires power, ground and tach signal. The tach will work at idle and up to about 4k rpm then goes to "0" on the display. I can watch the the tach and compare the value to the virtual tach in Tunner Studio
they match until about 4k at that point the virtual tach will continue but the Glowshift Digital tach goes to "0". I have put a filter inline also from Glow shift GS-Tach-Filter Signal Filter same results.

I have the TACHO set to NORMAL on the ECU, the other choice is half Speed it did not change anything when I made this change same results.

Any ideas?

thanks much
