I'm not 100% sure if what I am hearing is pinging but under hard excel in 2+3 gear, I am getting almost a "metal rice crispies" type of sound with a simultaneous slight loss of power. (it's the best I can describe it) It happens when the bike is hot. Anyone experience this with the fuel moto stage one AC and power commander 5?

2010 flhtcu, FM stage one AC, SE fat shot mufflers, CAT is still on, Power Commander 5and stock ecm.

The sound I'm getting is followed by a funny exhaust smell.

I used FM's "power map" and also their "mpg" map. No change.

I was thinking that maybe it's bad gas but I use nothing but the highest octane available. I was also thinking that maybe the sparkplugs are defective.

Anyone got any ideas? maybe cutting back a value or two on the timing???? I'm starting to think I should have gone with the SERT....LOL...JK!

 

It's running too lean.....not enough fuel injector pulse width.......or not enough fuel. Give it a little more before it causes damage.

 

I'm thinking that the fuel tables should be good. no radical changes....just a stage one air cleaner which the stock ecm should compensate for anyway. "fuel injector pulse width"-is that adjustable on the power commander?

I want to add that I was using a completely WRONG map for about 100-150 miles because the one I was sent originally was wrong. I am supposedly using the correct one now.

I just don't thing the fuel values would be causing it with a map from FM. unless of course the maps I have aren't correct.

A little bit more info. I looked at the ignition tables. On a map that I was using first (wrong map-too rich but no noise/pinging) is shown below:

And here is the one I am running right now. Look at the differences. the guys with PC5's will know what they are looking at. I THINK fuel moto might have copied and pasted the values incorrectly! would this cause my symptoms?

above, you are looking at the 8th column. look how the values are at +2 and go right into +3...the two tables are completely different.

 

Anyone? I looked at a bunch of ignition tables and THINK that can be an issue. Nobody has this set up and can add anything?

 

Drop the timing two degrees at a time in the troublesome area..

 

3&4 degrees is too much advance.I had my 07. at -2 in a couple spots..

 

I am going to zero everything out and see if there is a change.
