Premium Member 2and3cylinders Posted April 12, 2022 Premium Member Share Posted April 12, 2022 It says adjusting CO but it's hard to see and there's no audio? This French video is unlocking what?? Link to comment Share on other sites More sharing options...

Premium Member 2and3cylinders Posted April 12, 2022 Author Premium Member Share Posted April 12, 2022 Could you please elaborate on what you mean and/or what values he's changing, why and how (direction)? I've calibrated (down) the APS* to smooth throttle response but didn't know about this adjustment on my fastest red 15. *or was it the TPS?

Supporting Member knyte Posted April 12, 2022 Supporting Member Share Posted April 12, 2022 That was a quote in the comments by the creator of the video. Sounds like air/fuel mixture, but there's no reference... for ex stock values and what increments to adjust and why. Leaves more questions than answers! Sounds like you probably adjusted the APS...something I've yet to do!! 2015 FJ-09 / FJR touring bags / oil plug mod / Evotech rad guard / SW Motech bash plate / VStream touring windshield / Seat Concepts: Sport Touring / Vcyclenut ABS rings (speedo correction) / Cosmo RAM mount Link to comment Share on other sites More sharing options...
nhchris Posted April 12, 2022 Share Posted April 12, 2022 Am I correct in thinking that the optimum fuel air / fuel ratio is 14 to 1? If so will this recal procedure set the MPU to that value?

Premium Member 2and3cylinders Posted April 12, 2022 Author Premium Member Share Posted April 12, 2022 Have to check my maintenance log but likely was the APS, it's just I likely did iy a few yeas ago and my memory hasn't gotten better since then. As far as what he's adjusting, with more data, I'm not going to experiment. The French video translates to unlocking but what? I hope Macron wins, otherwise our poor French two-wheeled brothers and sisters are going to be in big trouble! 1 Link to comment Share on other sites More sharing options...
skipperT Posted April 12, 2022 Share Posted April 12, 2022 -This is not “unlocked” on US models. Needs dealer software. -the +/- value doesn’t equal anything that you can directly put a value on without Exhaust Gas measuring equipment on each cylinder ex pipe -it DOES slightly richen or lean out the mixture in EACH cyl at idle and very small throttle openings. -think of it like a Pilot Screw adjustment, @2and3cylinders -this is NO substitute for a reflash or “live” fueling adjustment by a Power Commander. -Skip 1 Link to comment Share on other sites More sharing options...

Premium Member 2and3cylinders Posted April 12, 2022 Author Premium Member Share Posted April 12, 2022 I was just curious, as I had my ECU flashed years ago by Dave at Vcyclenut. 1 Link to comment Share on other sites More sharing options...

My advice (FWIW) is do it! I noticed a discernable improvement with my machine and I'd already had an ECU flash. As always...YMMV. 🙂 1 Link to comment Share on other sites More sharing options...

I had questions about that when I first got the bike. After getting my ECU flashed I called 2WDW and asked them if it was something worth adjusting, their short answer was, if you have the ECU flashed with a correct fuel map, DO NOT mess with the CO settings. 2 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
