intermittent fault code 20 & engine light

To determine if there is a cylinder that is running cooler than the others, indicating a mis-fire.
If you have a FCE, consider calling IVAN. I understand that he may give you a credit towards a RE-FLASH on your ECU.
This is by far the best mod that I have done.
 
Problem is I am in the UK lol. It's Ok, I know how to deal with it, it's only a problem when I eventually come to sell it..

Well, its been a long time since an update...

I still have the bike and I still get that same fault code, however I have after many years of not a lot of riding, sussed how to manage it. Basically, starting from cold, 80% of the time the code 20 will appear and idle is a little rough. All I need to do is wait until temp reaches 101 degrees and the fan kicks in. Turn off, turn back on, and its gone all the time the bike is warm.

I did contact IVAN and the great guy sent me a few old units that he had from part exchangers for the ECU flash. The exchanged item worked for a few months and the fault came back.

Long story short, it has to be a fault of the FCE (although I haven't tried it without...). The bike only throws the fault when its cold and once it reaches the correct temp and the fan kicks in, its gone. All those reading in to the pressure sensors etc I think you are headed down a wrong path in the way that the bike is just getting confused with all the 3rd party kit attached.

Its almost summer here in the UK, happy riding!

Wow, I'm having exactly what you are having with my FZ1S 2006, but this time I started to lose power when revving at the point the bike stalled while trying to accelerate from 1st gear, then after I restarted I noticed the code 20 came up and it run better than without the code 20 however usually the code 20 comes up when the bike is really cold or cold days this time the code came up on hot engine hot day, I checked the sensor readings on diagnostic mode and they are normal, next step for me is to lift the tank and check the hoses...
