I'd like to get my 2016 BMW S1000XR running better. It seems to run rich otherwise it rides fine. My goal is to improve rideability and not outright power. I have a full exhaust with Rapid Bike Evo fuel module. Rapid Bike Evo has a long term tuning/adaptation function that utilizes the factory [narrow band] o2 sensors.
I can add autotune feature with Rapid Bike "My Tuning Bike" module which includes adding a wideband o2 sensor. With this addition the modules are suppose to read the air/fuel 50 times a second and make adjustments to the fueling instantly to achieve whatever air/fuel I set it to. It's an close loop system so it'll adjust to the enviroment (temps, humidity, elevation etc). Also it has an option to have different maps for different gears. Of course without the bike on a dyno I wouldn't know what power/torque its making but that is not the goal.
The other option is to use the standard Rapid Bike Evo module and get it dyno tuned. Pros would be I would know how much power/torque I'd be making, and if the tuner is good I'd improve the rideability. Cons would be that it's an open loop system so the tune would be static no matter how the environment changes. Also if I add modification it would need to be retuned.
I called Seacoast and spoke to their dyno guy Charles. We spoke about my set up and goals and to my surprise he actually recommended the autotune first then dyno if I really want to squeeze out more. He said the autotune can build a map/tune faster and better, and this is what he does on his personal bike. In addition to using an autotune he puts his bike onto the dyno to proof the tune. So the fact that he is recommending something that he will not make money on is encouraging as how good autotune is.
I also spoke to Rob at Rob's Dyno. This is before I learned about autotune so it was not part of the conversation. Basically told me that he can do anything I want and cost would be $300.
The cost between a dyno tune with Rob and auto tune is basically the same. What Charles at Seacoast said really stuck but I'd like to know what your experience is with engine tuning.
So has anyone had experience with either or both? Please share.
