Not sure who the OP is at this point in this thread. I will almost certainly get a wideband O2 to go with my headers in a month or two though. My VFR is stock right now, except for "mods that don't matter but people think they matter" like the snorkel and flapper. I am pretty sure I can feel the map steps (aka piecewise linear logic) right now when I am feeling around for them, while the drop/surge behavior is gone. I can only imagine the wideband sensor tuning makes them less obvious, along with making smaller pieces in the map of course.

Interesting...thanks! Anyone play with the fuel injection and ignition advance much? The manual doesn't say a whole lot other than rider preference plays a part :lol: I'm not too worried about tuning at WOT, pretty happy with the mid-range steady state and roll-on behavior. Like if I got no more improvements and never had drop/surge behavior come back, I'd be content. Useability of the bike is waaaaaaay up, it's nice not having to futz with gear and throttle management too much in corners!

Again...the manual could be better. But my bike is automatically tuning itself with the stock O2 sensors as far as I can see, and in line with previous posters' examples: I've only jetted up and down the highway a few times and gone on a few errands. So very little time spent above 7,000 RPM or with lots of throttle for the RB to observe. The numbers match my feeling as to what it's adjusting to, where the bike is happier sitting between 4K and 6K RPM without downshifting as much. From what I can tell, the "RBo2 Active" box must be checked for it to use the O2 signal. Mine was checked already. What I did just enable tonight...I think...is ignition and fuel advance (section 3.6.3 in the manual). Will see if that makes a difference tomorrow. For those who might be interested, here's where I ended up putting this thing: That's the RB Racing unit on the left side of the photo (right side of the bike), with the USB and other cable plugs inside the plastic bag by the rear brake reservoir. The red rag on the other side is around my shock reservoir (I have some neoprene foam sheets coming to make all of this look a lot nicer). The tools are in there...but hidden under the center spine, running between both pockets. I can pull out the RB unit or the shock reservoir very easily and get to them. The harness has just enough length to meet the stock O2 sensors on the left side of the bike, running right by the rear cylinder heads and down inside the frame near the coolant reservoir. The other connectors have excess length that's loosely running under the fuel tank on the right side, and coiled a bit behind the plastic body panel in front of the rear brake reservoir. In other words...this thing is clearly meant to go on the left side of the bike, but my WP shock was there first!

The software ran, but I didn't see anything obvious like "Self-learn" or "optimize," it had some windows that looked related but nothing clear. Kinda like the website 😄 I've put about 80 miles on it, I'm going to go down to the garage with my laptop and see if it made any adjustments in a few hours.

Well that was a successful test ride! I want to see how it does on longer trips, but I think this absolutely defeats the annoying drop/surge behavior with closed loop control. Did a normal start, full ECU boot, and never did the bike obviously lean out power on me. There were a couple times later on in 4th gear around 5K RPM that I thought it was dialing it back just slightly, with the RB maybe adjusting it right back...but it was so subtle I'm not completely sure, where the Honda dial-back is very obvious. Power curve is very obviously filled-in mid range too. 5th and 6th are much, much more useful and I didn't have to downshift nearly as much. Bike wanted to hit every ramp much faster than usual, which is what I think most people are looking for. No more flat spots 😄 Oh, and I managed to shove my tool kit under the center spine of the rear subframe, across both pockets. It'll be awkward to get them in and out but I really don't use them that much anyway. Will post pictures later. Going to be a while, but now I'm very interested to see what the mid range will feel like after I install the VFRD headers. And come back with a wide band O2 sensor of course!

Ok I have it installed, and plugged in everywhere. The harness was clearly meant for the left side of the bike where I have my shock reservoir so it took many tries to get it to go far enough on the left to the O2 sensors. May re-attack and alternate spot later. But for now, on to riding! So question...bike starts, Rapid Bike software connects to the unit via USB just fine and shows bike status. Appears to have a map loaded already. Do I just ride this thing for a while and let it figure itself out? One other thing I had forgotten about...I actually did the O2 sensor eliminator thing with resistors ~15 years ago. At first I thought "WTF" but then as I pulled the tape off I recalled I did it. Sadly, stock bike still goes into closed loop mode unless you do the key trick. Now that I know what no closed loop looks like...the O2 sensor eliminators by themselves do nothing to change it. Hopefully the RB does. I can see voltage from my stock O2 sensors and they are in line with what I expect from cars idling so...here goes, suiting up for a late night grocery-get and test ride...

Here's where I got it: https://rapidbike.us/contact Don't know why, but the software link is in the contact page. The website has confused me on a regular basis. I'm just glad the physical install instructions they mailed with the device are pretty straightforward!

Oh, and the RB Master Free version software also asked to update something itself following download...there's that too. Have not installed my RB Racing or played with this yet, but the software appears to run.

I just loaded my software this morning. When I did, Windows prompted me to install a different version of .NET framework. I want to say it was 3.5, which is now present on that laptop next to 4.8. The desktop I'm on already has it, so this may not be the 100% answer... If you want to see what you've got, type "Windows Features" in the search bar and click on "Turn Windows Features on and off" when it comes up.

Sure...you're selling one in Oceanside a week after mine arrived in San Diego? :lol:

Received my RB Racing unit and an M18 plug and gasket today. Gotta get my front suspension re-installed so I can tackle this next 😄

It was one of two options with the buy. Slightly wider gaskets that don't intrude into the inner pipe diameter, and passivation.

I do a little bit - but I also don't want to cut into my new Seargeant 😄 It comes with a little storage area under the pillion spot as well. Really good spot for insurance and registration cards, will see how much else I can get in there.

Oh, I'm thinking of re-arranging the tools into the remaining space in the underseat tray and inside the saddle, to free up space on the right side for the RB. Among other things I could probably slim down the tool kit with some smaller alternatives. I'm not sure I'd like to hassle with wiring in and out of the saddle :lol:

Well, maybe between the tiny cargo slot in my Seargeant saddle and what space is left towards the back of the two pockets, I can make something work. Time to get creative...

My RB Racing unit shipped! Question for all of you with a 6th gen, where did you put it? I have the reservoir for my WP shock in the left storage compartment under the seat, and the VFR tools, etc in the right side, so hopefully its small enough to fit in elsewhere, or somewhere among all those thing. My options for relocating the reservoir are pretty much zero and I could relocate the tools if i have to, but don't want to have to run saddle bags all the time.

Just ordered a Rapid Bike Racing to go with mine when I get around to installing it. Just to verify, I need an M18 1.5 pitch plug to fill the wideband sensor hole right? Didn't order the MTB module this time around, maybe later.

Ok, I think this is the info I'm looking for! I too consider myself pretty good at figuring things out, and yet the Dimsport's website also leaves me with many questions :lol: So the Racing module will self-tune with the stock sensors and I don't need the MTB thingy yet...that's great!

Interesting. Better than stock, no lean mixture issues? I think I mentioned elsewhere, I'm a fan of defeating closed loop control via the key switch and happy with that (no surging, etc.). I would like a RB at some point but if I could piecemeal this out over time that would be swell too.

So I have my VFRD production headers in hand, waiting for install. To make it work right, I think I'll likely go with the RapidBike Racing module when I get around to install it. Does that mean it'll work with a pre-programmed map or one I can adjust, until or if I get a My Tuning Bike module that plugs into a Bosch wideband O2 sensor?

Got my header in hand! I should probably ask this on the Rapid Bike thread, but after looking at all the sites (which are not clear)...it looks like the Rapid Bike Race module will work with the wideband O2 sensor bung, and I don't need the You Tune module unless I want to futz with the settings while riding (I do not really...or at least not now). Should get everything including auto tune, right? The header is a few items down my work backlog on the bike, so not an urgent thing to figure out now. Front suspension next, then maybe a rear suspension overhaul. Bike is running *great* right now with the closed-loop defeat method via key switch that some 5th gen rider figured out so not in a rush. No annoying surging on the highway at constant throttle...
