Daz....its at all throttle openings........not just under 20% throttle..

I was under the impression that the O2 sensor only reads between 2500 and 6000rpm? which is where the O2 sensor problem lies which is surely more than 20% throttle?

I could be mistaken however.

go back to page 6, 9th post down...i believe your post with a link.....lol

Indeed I am mistaken!



Sorry :mbounce:

I give up...


I can't do it :Christo_pull_hair: :Christo_pull_hair: :Christo_pull_hair: :Christo_pull_hair:



I've got the mod made up here on a proper board now and when I try it on a 3.7V battery, it works and you can visually see it working because of an LED I've added to it.

But when I attach it to the bike which is 4.92v, where more is better, it doesn't.

Even in the simulations I've ran on the computer it works flawlessly.

I've worked on this every spare minute of my evenings I've had this week till near 11 - 12 o'clock and some evenings not eating because I've been so busy with it.

Something just isn't right and I can't work it out :Christo_pull_hair:


Edit:

Bah, One of the wires on my mod just came off and it still did the same thing, so it's actually... NOT working as expected on my desk :(

Mate I think we need to keep our little O2 eliminator project out of this thread so we don't confuse things.

Just to enlighten everyone, I have found a way to turn off the O2 sensor on my 09 XTX & can map the bike perfectly with no surging problems, dazmatic has confirmed this by testing this mod for me on his XTX with O2 sensor.

Everyone in the tunning industry is trying to tune the closed loop circuit with O2 simulators or Eliminators, I have taken a different approach by turning off the closed loop circuit so the ECU only runs on the open loop with no O2 sensor.

I have made a the device that can turn off the circuit completely with relays & switch's but is to complicated for the average rider to wire up himself, dazmatic is helping me make an electronic version so we can reduce the amount of wiring & connections, so stay tunned we might have something new that know one has done before.

yeah, sorry bud.

I think when you two have cracked the 02 sensor, it will merit your own thread...... (try a much lower voltage!)......and get off my thread!!!!!!!

Results of my third Dyno session.

DNA Stage 3 Airbox, PC111, CCC.

I now have all the figures from my three dyno sessions all on one sheet, with the same Correction Factors. I am now using these figures below........

As a reminder, at my first dyno my bike was Standard, except for a Power Commander.

Dyno session 1. Result. 42.32 hp 40.73 ft/lbs. A/F 12.25 @ 6000rpm

My second visit was with the Airbox, DNA "Open Ackro" Map, CCC Exhausts, PC111.

Dyno session 2. Result. 47.18 hp 44.80 ft/lbs. A/F 16.5 @ 6000rpm

Now with my "custom map"...

46.24 hp 45.02 ft/lbs. A/F 13.9 @ 6000rpm


My third visit, as I wasn't happy with the results and "gains" above, they kindly offered to have another look at it, without charge to me, and I asked them to set the A/F at 13.2:1.

Dyno session 3. Result. 44.87 hp 42.43 ft/lbs. A/F 13.2 @6000rpm.


So.....I STILL AM VERY CONFUSED!!!!! AND STILL NOT HAPPY WITH THE RESULT!!!!
(A GAIN OF ONLY 2.5 HP/ 1.7 FT/LBS FROM MY "STANDARD BIKE" !!!!

Well, from other figures quoted I should be on a "Gain" of around 7 hp, 6 ft/lbs torque, from a Standard bike, and a A/F Ratio of around 13.2:1 is supposed to be the ideal area, but CLEARLY, not in my case!! (my bike produced the most power at an Air/Fuel ratio of 16.5:1)

Either there is something wrong with my bike, or the dyno A/F figures are wrong.

SO.....I have phoned Dynojet UK, and they are going to study all the Run Files, and get back to me. I just hope there is nothing wrong with my bike, its only done 900 miles! And I hope that we will end up (eventually) with a nice and juicy "gain".........the saga continues.......

Keep us posted. I hope you'll get the results you should have!
