Can you post a pic of your bunghole?
It's probably got a bungplug in it...
Interested to see where Rottweiler positioned it
Photo of bungplug plugging bunghole:
Well, that all worked out better than I had imagined
Lol. Almost like we're all grownups!
Don't call me that
You were saying...?
Whats going into that bunghole? (i had to)
An AFR sensor... gently... but firmly...
Brass, minus the ballz..
I think I have seen an install video on the web where they mounted a plug into bunghole as well as another similar into air intake. The system self-adjusted to use spare air intake on top of the main one and there was third plug going into intake manifold. But in the end it all 'exploded' so something must have gone wrong. No motorcycles were hurt in this video
I was thinking about autotune too but talked with a dyno guy who asked what I was after, I told I wan't to tune a reliable setup and then just ride ever after. He suggested only mapping for me and autotune only if I wan't to constantly try different setups and/or otherwise tune all the time.
Ordered pcv and going to dyno later when bike is otherwise good to run.
That was my thought as well. In reality, as I think about it more, autotune really shouldn't increase fuel efficiency much over this race tune, just make the tune a little more optimal in all conditions/all elevations and give you the AFR display so you can see where it's running at all times.
The fuel efficiency comes from it running extremely lean on the stock tune. The PCV tune fixes this extreme lean condition, also reducing fuel economy.
I expect a more efficiency-minded decat tune could be produced by allowing the tune to remain lean at smaller throttle openings, tapering to richer under greater load. I assume the PCV has this capability, but haven't reached out to Rottweiler about it yet.
Another full tank gone, another 39 mpg tank. Hurts a bit.
The auto tuner I have on my HOG constantly modifies 2 separate maps. One is performance, and the other eco. The tuner watches how I ride and knows if I am on it, or just cruising. Then after I cycle off the key and back on it tweaks about 5% of those 2 maps, slowly over time, optimizing each. Different perhaps than the PCV, as my tuner completely replaces the OEM ECU. I also had to install O2 sensors. But if PCV could switch between 2 maps which it has optimized for the specific rider, that would be mint.
hi nowwhat, just wondering what stock header oxy sensor (bung) you threaded the Dynojet autotuner wide band sensor into? does it matter?
He didn't. It's an additional bung, pictured above on my bike.
