Speed adjustment Carb legal flashpro

Post by guywitthesi »

I have a FD2 final drive that makes my speedometer read 10mph higher. What percentage should I set the ECU and or the dash to?

You will have to try different values and see what works best for you.

Update
I was able to make the speedometer read the same mph as my gps unit.
I set the DASH to -15 and left the ECU at 0, I noticed changing the ECU effected the idle speed.
