I am not an expert on engine fueling (that's your dept) but from what I have read I believe the correct answer is heat. Overly rich mixtures may cause unspent fuel to enter into the exhaust flow. When this hits the cataclysmic perverter it causes super heating. This can lead to melting of the honeycomb structure and the metals (catalyst) it is made of.

Agreed

It takes much richer mixture than any fueling mod we're talkin' 'bout here to melt a cat. Think rich like two out of six in a car not firing and your wife drives it around town anyway, thinking it would blow itself out. DAMHIK...

Yes. The ECU always uses the air temperature input and barometric pressure to calculate air density. With that information it determines the length of the fuel injector pulse necessary to create the desired fuel/air density ratio.

Regarding the afterfire (aka backfire) popping from the tailpipe, that issue is primarily a function of the inconsistent Overrun Fuel Cutoff routine in the ECU.

Moving the throttle around within the range of fully closed to slightly decelerating is what creates the unburned combustible mixture in the exhaust tubing, and causes the backfires. Tailpipe popping can be greatly reduced or eliminated with careful operation of the throttle.

To describe the 'workaround' throttle operation as simply as possible, the throttle should be either holding the bike at a constant speed, or opened more to cause acceleration. If you want to decelerate at more than a slight rate, close the throttle fully. When you want to accelerate, or hold the new lower speed, open the throttle quickly and directly to where you want it.

The above takes practice of course. And I don't like the idea of having to adapt to the ECU. But without other electronic measures there's no way around it.

The reduced air temperature input has some slight effect on backfiring, I don't know that I'd call it significant, but there is an improvement. As you have seen however, some bikes experience more improvement than others. I ascribe the difference more to the rider, which I suppose is a good example of 'Your mileage may vary.' (YMMV)

Regardless the name, there are better ways around the problem of tailpipe popping, afterfire, or backfire.


Thanks for that great explanation. So what is the ECU doing when I completely remove the ccp and this stops the tailpipe popping?

Thanks,

Just bought 2, one for my 2012 GS/A and one for my 2002 R1100S Boxer Cup Prep...

I'd really like to receive them before the end of May if possible. I'm traveling to Alaska, leaving the first week of June, on my GS/A.

I'm even willing to help with the assembly, as I have stated in at least 2 pm messages sent... Let me know...

I'm really a very slow putt-putt type of rider, lucky to get into third gear on most rides. Today was one such day, motoring along in 3rd, in the slow lane up Ashby. When all of a sudden I realized the bus to my left was changing lanes, into my space, man.

Looking back, I'm grateful for two things: A quick reaction to gas it right the hell out of there, and the sudden rush of acceleration that the ICEE AIRE gave me. Two to Engineering and Marketing.

I would like mine by the end of May too! I ordered it in January.

OK, this has probably been asked or is posted were normal people should be able to find and read it easily... butt.....

Is the IICE Air I got for my 2009 F800GS compatible with the new 2013 F800GS?... not that I am officially looking ;)
