We have a 2014 Ultra - Stage 1 with a rough idle.
It has new fuel and plugs, cleaned injectors, air cleaner. Leads tested - ok.
Compression test 205ccp in each cylinder. No vacuum leaks detected.
We have tried 2 different SE maps to no avail.
Data collected indicates fluctuating timing from 14 - 23 degrees.
MAP voltages from 1.1 - 3.8 v .
I set the timing on both cylinders to 20 deg at 0-50 kpa and 750 - 1250rpm.
Still fluctuates !
Disconnect MAP sensor and bike runs significantly better.
No broken wires found.
Do I have a faulty MAP sensor?
