As most of you probably already know R18 has a severely restricted lump of an engine possibly hiding potential of 10-20% more power just by derestricting it and letting it breathe.
If we would compare it to the closest Harley 107 or 114 M8 engine, with proper de-cat exhaust, more free breathing intake and derestricted intake tubes + getting it properly tuned we could see 100-120 HP from stock 91.
Right now there is yet to be released tuner or aftermarket ECU for Bmw R18 and that is the main problem. All of the new bikes stock from factory run very lean and further introducing free flowing exhaust and more air makes it very lean and potentially only hindering performance and longetivity compared to stock.
With R18B and Transcontinental I think there is a potentially big market for these aftermarket ECU solutions but none are currently available, year and a half after initial release of the motorcycle.
I have contacted all of the tuners offering ECU / remapping solutions and here are the results:
DIMSPORT/Rapid Bike - No intention at the moment to develop ECU for Bmw R18
PowerCommander - No response
Brentuning - They have started the development but they need someone lending them a bike to finish ECU development. They are from Michigan so if someone is local please get in touch with them so we can finally let this motorcycle breathe.
If you have any other pieces of information about aftermarket ECU for R18 please share.
p.s. I got also mixed information from local BMW mechanics telling me that modern ECU fitted to BMW R18 has the autotune capability via lambdas to overcome any additionally introduced leanness and compensate it automatically so we are free to "tune it".
p.p.s. There is a ton of custom R18 out there with full custom free exhaust and intake modifications, not sure if they just run stock ECU or is there some "secret" solution to adjust air and fuel levels.
