2009 street glide, put the woods 555 cams in with the fuel moto x pipe. Dyno tuned and has been running great. I've noticed the fuel mileage continues to get worse. Last fill up I got 19 miles to a gallon. My dyne guy checked it out and said it's the fuel induction module and it's not closing. Basically running at or above 63 steps after warm up.

Anyone else run into this?

 

Nobody?

 

I'd call Jamie at Fuel Moto and get yourself some solid advice. You never said what tuner your runnin?

 

I'm running a 09 FLHRC with a PCV/Autotune and I weigh 225lbs and get about 35 mpg city and about 45 mph hiway. The new stock 103 FLHRC gets the same as me. Something definitely wrong with your set up.

 

I would guess you have an intake leak.

 

Running the se super tuner and have checked no intake leaks.

 

Well if you are getting 19 mpg, you are running so rich that you should leave a black smoke trail wherever you go. Have you looked at the exhaust or the plugs?

 

So...after three days at the dealership found out it was not the fuel induction module. It was a bad ECM, now back to the dyno and can pick up tomorrow. Hopefully my mileage will be back up in the upper 30s

 

How did they know it was the ECM?

 

Going back and forth with the motor company, tech support decided that it was the ECM failing.
