The harness secured with a zip tie? Can't tell from the picture.Comparisson of OEM O2 sensor (left) and the Bosch wideband from the autotune kit (installed)
The harness secured with a zip tie? Can't tell from the picture.
It was still using other sensors to make changes, so in the end the bike would ride just fine and change it’s fueling based on environmental changes.Gives me piece of mind to run a proper closed-loop fueling system now knowing that the bike can monitor its AFRs. Something was bugging me about cranking the bike up at 5C in the morning, riding through a 30C afternoon and returning on a muggy 20C night and realising the bike would not actively adjusting fueling for these atmospheric conditions and just go off of the static PCV fuel trims. I think the PCV kits are slightly different now but atleast for my install, the instructions had me disconnect the stock O2 sensor from the bike and essentially run an open-loop fuel system (no connection between ECU and the stock O2 sensor; the sensor was basically being re purposed for an exhaust plug).
Another thing I wanted to mention here, with the AutoTune install, is the disabling of the PAIR system. I did not want to go with the full-blow PAIR delete with block off plates and all that so I just blocked the air hose at the airbox with a vacuum cap. PAIR system is still on the bike just blocked.
My PAIR hose is still connected to the airbox. I stuck a vacuum cap inside the PAIR hose from the airbox side. Its not like i pulled the hose off, capped it and left it disconnected from the airbox (if im understanding you correctly).Did you block both hose and airbox or just hose? You need to cap the airbox too or you risk sucking in unfiltered air.
You do know the proper operation of the auto tune is to turn it off after a few weeks, correct? It’s not meant to be an always on thing.
Gotcha...as long as you are confident it's not going to come loose and grenade a cylinder. Personally, I wouldn't chance it.My PAIR hose is still connected to the airbox.

Accept the trim table after every ride until you reach a somewhat steady state. Have zero trim table will never happen due to changes in riding style, conditions, temp, elevation....lots of variables.Where'd you get this from? Wont be doing much after a while but itll keep doing something. Bringing down the trim adjustment range from +/-20% to +/-5 to keep it from throwing skewed numbers after a while. I guess you could disconnect it after the bulk of the adjustments have been made but i dont see the need to disconnect it or anything potentially wrong with single-digit adjustments long-term.
As made obvious by this thread im new to this so enlighten me.
Yeah its in there good rubber on rubber and its jammed in there. The top half of the airbox is actually holding the edge of the cap in place just the way it worked out. Had to snip the vac cap a bit for the top half of the airbox to seat properly (essentially seating on part of the vacuum cap). Hard to explain and i shouldve got a picture before i closed it up but im confident it wont pop out.Gotcha...as long as you are confident it's not going to come loose and grenade a cylinder.

What is the size of OEM O2 sensor bungActually the pc5 kit should have an o2 sensor plug in it, to avoid said error codes and allow for proper map building.
I mean for CBR 650F the bung is of 18mm or 12mm, if the stock bung is of 18mm than I don't require to weld the Autotune Bung on my exhaustNot sure I understand with the quote. The bung is an electrical connector so only comes in one size.
