I've got a 2018 R NineT Classic and have just placed an order for a set of Remus headers to go with my Akrapovic single silencer. As many (not all) would agree, when modifying the intake and or exhaust, something should really be done to assist fueling with the more free-flowing air / exhaust, especially given the Euro 4 bikes tend to run on the lean side due to emissions.



I've done a fair bit of reading across this and other forums regarding booster plugs, AF-Xied modules, Re-Maps and Piggy-back modules (AKA: PC5, RB, etc) and weighed up what would work best for me. Given I'm still well within my warranty period, I quickly ruled out the re-map and more complex piggy back modules, which left me with a Booster Plug or AF-Xied. After even more reading and weighing up both camps, I was leaning towards the AF-Xied side as I believe (from what I've read only) that the BP works initially, but is slowly adjusted out of the equation by the factory ECU. So I was set on the AF-Xied. Given I'd need a twin AF-Xied module for our boxer, the price for such a simple module was more that I was willing to pay. So after a little more searching around, I came across what I ended up purchasing, the Rapid Bike EASY!


The Rapid Bike Easy essentially works the exact same way the AF-Xied does, but in a much neater package and at around half the price. It's a simple plug and play device (easy to remove in warranty situations), no cutting, waterproof connectors, and an easy to follow guide stating the optimal settings for your bike.


I'm yet to use the module as I'm still waiting on the headers to arrive, but will report back once all done.


Below are a few photos of the unit. Also note the same module can be used on a number of other BMW models, including all 1200 series boxers through to 09-2018 S1000RR's.


If anyone's used one of these before, I'd be grateful if you'd chime in and let me know your opinions, findings, tips etc.. Or if people have used similar units that have any useful info - that would be great too.


Thanks..

This looks a good solution at reasonable cost.

My understanding from reading is the 'easy' intercepts the O2 sensor output to fool the cpu into slightly richening the closed loop mixture. This shouldn't effect warm up (below 80 degree temp) and higher throttle and higher revs as these are outside closed loop operation.
However with use (100 mile or so) does this also richen the 'trim' values in the cpu so that open loop is then also made slightly richer?
If so I should get a slightly more drivable bike and may run a bit cooler engine temp, but no big hp gain. It may improve economy slightly due to better drivability. It may also have a slight detrimental effect on the 3-way cat efficiency.

Sounds just what Im after but would love to know if it works before purchasing. Ill be watching this thread for any feedback good or bad.

I’ve had a rexxer remap on my ducati as well as the rapidbike evo. Rapidbike was probably the better of all the piggyback systems I’ve used prior which also included the bazzaz and powercommander, as it constantly adjust the values to adding/subtracting fuel. I haven’t heard of this EASY module, pretty interesting.

So prior to purchasing the module (can be had for AUD $250) I found an independent place in Sydney that had a 2017 Racer in and did a fair bit of before and after mapping of the RBE. It looks as though the owner of the Racer (I don't know him) had fitted a set of Remus headers and assumed the bike could cope, or perhaps fitted a booster plug. None of which was disclosed, nor did I think to ask at the time.


Here's a link for a 'before' dyno video. It's a facebook video so not sure if the link will work for everyone: https://www.facebook.com/DnACustomCycles/videos/2270791636514130/
Comment for video:
*********
Having fun with this new #bmwr9t on the #Dyno today, we did a stack of pre testing of the AFR readings at set 10/15/20/50% TPS settings using the #texatxb tool so we can see the ecu outputs and then carry out #dynoruns accordingly.
Now a lot of products make bold claims but the #rapidbikeeasy module backed it up with great fuel figures over the stock ecu.

Another video from the same place describing how they're mapping:
They state: "it’s a piggyback that tricks the ecu into thinking it’s getting 14.7afr but I fact it’s now getting 13.2. On an adaptive learning ecu it’s pretty cool"


Annoyingly they didn't post a follow up video, but did post the graphs (although not the best) on their facebook page.

Before and after fitting the rapidbike easy module. The solid middle white line on the graph is 13.2AFR (our target) you can see that before fitting we are in the hi 15’s and that’s why we have heavy heat signatures on the header pipes, now after the install and exact re runs we are pretty dam happy hitting target.

Feedback from the owner:
“I’m happy to report that the bike is like night and day compared to when I dropped it to you....
If I’m honest I didn’t realise how snatchy it actually was before.
It’s so much smoother than before & purrs in every gear at every rpm.
Happy camper. Thank you! :)

It would be good to know how tricky the install is.
Does the tank need to come off to attach cables etc
How many connections are there, just the two O2 sensors or more such as a power and earth.
Where are the O2 sensor connectors

Im assuming the box can fit under the seat in the tray.

I haven't done it yet (waiting on headers), but had a brief look and on a scale of 1 to 5 (5 being hard) I would put it as a 1.5.

Because they're in-line connectors, it's just a matter of unplugging the O2 sensor, plugging in a replacement plug, then plugging the original o2 sensor back into another plug. Repeat on both sides. So there's two plugs on each side.

The unit gets its power / earth etc via the plugs, so no need to tap into power / earth. 4 plugs and that's it.

I managed to route the cables up along the frame completely out of site without having to remove the tank. Just use black cable ties to secure them.

The unit is pretty small so will easily fit under the seat.

If the headers don't arrive by the weekend, I'll fit the unit up anyway and take a few photos for the thread.

So one would need to purchase two units for the 9T or do Rapid have a "BMW Cam-head R1200" package?

Cool! So they are adjusting the AFR of both cylinders with a single unit, as opposed to AF-Xied which requires a separate unit for each.

Certainly makes it EASY! :)

Exactly! Which is also how they can make it cheaper than the AF-Xied.

Although the O2 connectors are nice (waterproof) my only complaint (albeit minor) at this point is that they could have used smaller cable sheathing. It's just a little bulky / baggy, and although will be hidden, it would have been a nice touch to use something slimmer or more compact.

I may try hitting it with a heat gun to see if it will shrink down a little.. Or simply cut it off and get some of that stretchy sheath that will slide over the connectors then down to a snug fit on the cables.. Or maybe I'm just expecting too much! ;)

Will this module work on a 2017 Scrambler or is r nine t the only one listed?

Also I didn’t see the easy module on the rapidbike us site, where did you order from?

I can't see why it wouldn't work on a Scrambler. It's the same engine... As far as I can tell, it works for all 2014 through 2019 models..



I ordered mine through an Australian site, but can also be found here: https://calsport.co.uk/bmw-r-nine-t-14-2015/rapid-bike/rapid-bike-easy-plug-play-control-module/krbea-017 If you're outside the UK, you should get VAT taken off at the checkout.. Alternatively, hit up the US distributor... I'm sure they could get one in..

Hey for USA I just checked with them and they say it’s the same one they have listed for the bmw s1000

I drilled out the dB killers and the butterfly valve but my headers are stock with the cat in place, think this will be an improvement or wait to get headers before buying this?

Seems odd to me that it would be the same kit as an inline four, but I guess the cables are the same for the two O2 sensors.:icon_scratch:

IMO even on a bone stock 9T you would benefit from something like this. :)

Well, It looks like my headers are somewhere in the country, but that's all I know. I figured I'd go ahead and install the RBE anyway, which actually makes sense as It'd put me in a better position to do a direct before and after comparison on the unit itself.



The install was as the name suggests - Easy! The most time consuming part was trying to figure out the best route to run the cables..



In the photo below, next time I'd just run the cables under the cylinder brace (blue arrow) and not bother going over. It's pretty tight and fiddly going over and think it would be neater going under. The unit itself has a silver cover so the dials aren't exposed..



A few more photos of the cable run attached also.

Connecting to the O2 sensor is as simple as follows:


Unplug the O2 sensor, then connect A to A and B to B. Repeat on the other side.


Done.
