I mean, in all fairness Kev, do you think it's right to be dynoing and mapping these bikes knowing with the problem with the ECU?

Cause as it stands, as far as I'm aware, untill we can find a suitable solution that can be distributed for turning off the O2 sensor in the bikes ECU, its probably fair to say that you're only going to get a limited map completed on these if anything?

Kev, i only have 9 messages in my folder....so room for a little one! it never arrived.

I think he didn't really stick it in....(!)....But it cant be far off, or if it is, i will be really suprised......and driveability is my goal.........

They ought to go IN the exhausts, otherwise it's measuring the ambient air and would show a leaner AFR than what its actually producing, its why most lambda sensors on cars and bikes are straight after the manifold and before the CAT to get the most accurate reading possible.

Kev...you need to clear your message box again...it says you're full!!

I agree Daz, but on paper my bike looks bad, but goes like a dream....i think the AF wasn't measured as well as it might of been tho'...........but i dont think there could be much more of a difference in feel......

Yes, but like what was said earlier, the PC3/5 aren't able to map on these bikes very well because of the O2 sensor problem so the bike would still run regardless. If you were able to disable the O2 sensor and went back to remap, I think you'd find a couple more ponies and a much MUCH better AFR.

Daz, its only the lower rev bracket where the o2 sensor interfers..........come ride my bike...you will see how sweet she is now....:happy::unibrow::happy::unibrow::037::037:: 037:

I was only analyising with Kev......no offence!

I beg to differ...

First post on page 2, Paul quoting what it states on the PC3 Box.

Don't get me wrong, im not arguing, im just saying why you're probably getting a very bizzare AFR :)

If you look at the Videos on youtube, you can see the AFR Fluctuating between lean and rich by quite a substantial amount!

I've done testing for Kev and found that with a certain piece of equipment on the bike, that I'm able to map it perfectly, as is the same with Kev.
However, this Piece of kit is still very, very much in the development Phase and cannot be revealed.

This is all a debate about the A/F ratio reading I am sure the bike is running well. The last dyno run posted was using the exact same ECU as richardsracingmad is running.

dazmatic has been do some independent testing for me on my new O2 eliminator, I am still trying to find an electronics engineer to help me build the O2 eliminator, I know it works & can prove it, I just need some help in building an electronic version, I have a electrical version working but is to hard to wire up & sell for the average rider.
