Rapidbike and dyno

Hi all, I've got a 2017 1200s with a full Akrapovic system and a rapidbike evo unit... I'm finding the bike is running alot better at low rpm(much smoother) but it drinks fuel! I'm going to put the map switch on and get some dyno runs done... My question is, can I set up a economy map and performance one? Or am I just better using the bypass plug for when I'm doing long highway rides?

The RB Evo only supports one map, for what you are trying to do requires the RB Race

Buy the RB cancel plug and bypass the whole thing. Drive around a bit and report back. If you are commuting and not railing it, you can delete the RB unit and see how your ECU does (hint: mileage will jump from 33-44). Dave K has this set up and explains it in detail in other posts.

I'm in the process of setting up a dedicated map, which AFIK is possible. Poor economy and oil diluted with gas sucks. No flat spots rules. My RB doesn't even reek of unburnt fuel that bad, but it's out of bounds on the fuel dumps.

Dyno yours after switching and I'll do mine

$75 BTW for the RB delete plug.

I'm OK, you're OK

FALSE! According to Rapidbike Evo | DIMSPORT - ENGINE CALIBRATION SPECIALISTS :

Rapid Bike EVO supports quick shifter sensor (optional), multiple maps management, raising RPM limiter (up to 1000 rpm) and the elimination of speed limiter.

Cool, happy to be wrong. I hope it works for the OP.

Here's what Rapidbike suggests on how to use 2 maps (normal and leaner):


The real trick is how to figure out the correct O2SENS value. It surely changes the target A/F ratio, but Dimsport doesn't explain the relationship between these 2 values, just:
"this setting must be changed only by testing the bike on a dyno bench with a
gas analyzer system. This is the only way to proceed in order to verify which stoichiometric
value the auto adaptivity gets and avoid regulations dangerous for the engine"


As Youtune controller allows the maximum adjustment of O2SENS value in +2 to -2 range only, go really easy on the setting! Note - PLUS leans the A/F ration (I think, they go by: higher O2SENS = higher A/F ration = leaner mixture).
I'd add 1 to O2SENS value and ride the bike long enough to see how it effects A/F. If it's not enough - repeat and test again. Or, as Dimsport recommends - take the bike to dyno.

Also, O2SENS value changes A/F across the whole TPS/RPM range. It does not allow selective adjustments (like Dynojet AutoTune). The only issue here is that you probably wouldn't want to lean A/F @ WOT/rev limit range, but Rapidbike can't do that with OEM O2 sensors.

The other way would be completely disable "Auto Adaptivity" feature and just create 2 separate maps on dyno

Thanks for the replies. I have booked dyno time as I really wanted to get the fueling setup. Not sure if I should just go with a lean and a rich map or create 2 new maps altogether? I'm a little confused with the "auto adaptive" won't that just cancel the lean and rich out?

If you are going with 2 custom maps, you have to disable auto adaptivity all together. The adaptivity has to be disabled anyway during dyno tuning, otherwise it will interfere with the adjustments

I take it that is adjusting the table? I've got a bypass plug aswell, so will use that as a base setting.

BIG WARNING!!! It may be important for someone considering Rapidbike for 1260. The new harness puts the device on top of the battery. The harness is not long enough to move the device under the passenger's seat (like 1200). Unfortunately, the rider seat will NOT fit in lower position with Rapidbike!!!
I tried all possible locations for the device - nothing works. The only way I see is to buy a smaller Lithium battery and stuck Rapidbike between the battery and the frame.
Not an issue for me as I use the seat in high position, just FYI.
