How is THIS different ?

[TheRepairMan]

Hey guys!

Got a question!

I found a couple of links to "Adjusting the Co" or tweaking the fuel mixture of the FI ECU in the FJR's diagnostic mode right on the bike's LCD display, at least on the pre 06 models. 06s supposedly have a new fuel system and MAY not be adjustable.

https://www.fjr1300.info/howto/co_adjustment.html

How is this different, or less effective than tweaking with the PCIII ?

TIA

Did I miss that on the spec sheet somewhere?

The Co adjustment was before the PCIII was available for our bikes I believe.

With the PCIII you have a lot more functionality and custom tuning ability.

If money is a concern but you still want to richen your bike and make it smoother here is an option that has been suggested to me from a close friend who is a Harley, Yamaha, BMW mechanic.

The CO adjustment affects only lower rpm range IIRC, and the O2 sensor still functions. The PC varies the change throughout the RPM band, and the O2, being disconnected, cannot alter the mix.

RM is 100% correct.

BZZZZZZZZZZZZZZZ! Wrong.

Sparky's reply would be: IIRCIB.

The correct response is: 'If I recall correctly', I believe.

Rad, you're beginning to disappoint me missing these... Cold weather freezing the brain?

Randy, and all who replied, Thanks!

The term "New FI" was actually in an 06 FJR power point presentation linked in this forum back in September or October under "FJR Performance" improvements.

https://www.bikes-n-spikes.org/misc/misc.html

I and others here have the entire presentation on file but don't know if it exists on the web anywhere now.

It's worth posting a link to it here again if anyone knows where it can be hosted.

Exactly what the "New Fuel System" consists of technically is a complete mystery to me. There was a mention however of it being a "feedback fuel system" which isn't anything new at all.

I haven't seen any further info and have only speculated about the fuel trim

non-adjust-ability based on what I am reading about the 2006 emission requirements for the US market.

I hope my speculation is totally incorrect.

Anyone who would like page eleven "FJR1300 Performance" or the entire presentation in zip file form sent to them can PM me with your e-mail addy. Note that it is a large file but I'll give it my best or refer you to someone who actually knows what they are doing. :blink: Hey MARK ! :lol:

Found this generalization from Yamaha about the new fuel injection system

(which really tells us nothing), very frustrating that even with all the rag spys at work that 06 tech info is slow to get to us avid FJR fans.

"Advanced fuel injection system is ideal for long-distance supersport-touring, delivering crisp, seamless throttle response in a variety of altitude/weather conditions.
