Hi everyone, I have a 2006 EG with a 95' stage 2 bb kit. I'm using the correct se mufflers and ecm download from my sert. I took the bike out a mounth ago for my first ride of the year. I noticed the bike would ping slightly at 2100-2200 rpms only, up a slight hill, in 4th or 5th gears. Last year I had no problems and my riding style is the same (mostly touring). The bike has plenty of power and does not ping at any other load or speed. If I climb the hill at 1900 rpm, no ping. I ran a tank of fuel through the bike and it still pings. I use 93 octane fuel only, mobil or exxon. Any suggestions would be appreciated. Thanks, Vic

 

Your post mentions the "download from the SERT". If you do have a Race Tuner, it should be a simple matter of taking the specific map that was downloaded into your ECM, and backing off the spark advance just a couple of degrees in the RPM range you mention. Don't know how much you've played with the Race Tuner, so this may be Greek. One question might be the value of "slight hill", and what that means to the ECM as far as Manifold Absolute Pressure. Here's a guess, that might be around 50 kPa. My '03 Road King 95" with Andrews TW37 cams (fairly high cylinder pressure) is running the following spark advance:

2250 rpm 30 kPa map = 39 degrees
2250 rpm 40 kPa map = 39 degrees
2250 rpm 50 kPa map = 34 degrees
2250 rpm 60 kPa map = 33 degrees
2000 rpm numbers for above kPa: 30, 30, 32, 30
2500 rpm, 38, 40, 36, 35

The ECM interpolates the spark advance for rpm values between the ones in the map.

You can also make a recording, the SERT will show you Knock Sensor values, and how much the timing was retarded when it happened.

Or, as some will probably suggest, kick it down a gear, 2100 is too low for climbing hills.

Oh, and if you don't have a SERT, just drop a gear!

 

Thanks for the reply. I was thinking of pulling some advance out at that rpm,but it ran good last year. I put 6000 miles on the build. Thanks again.
