GYTR vs stock '15 WR450
Posted May 29, 2016 - 07:15 AM
I have a '15 WR450, removed exhaust restrictor, throttle stop, and air box snorkel.
I have been reading up that the stock ECU can be modified with the Yamaha EFI power tuner. I have also read that adding in a GYTR ECU makes the bike more powerful all round.
My understanding is that GYTR tuner only works with GYTR ECU and Yamaha tuner works with stock ECU.
My question is, is there any point purchasing a GYTR ECU if the stock ECU can be mapped (as far as my understanding goes) to match competition ECU anyway?

Interesting, this site says you can.
Acorrding to other Aussies, the showroom models are already GYTR converted, and the ECU you have is the GYTR version....at least on the '16 model..........but yes you must change to the GYTR ECU to remap it.....which your bike may or may not already have.

Yup, Aus WRs have tuneable ECU as standard. They are pretty much entirely uncorked from factory sans slightly restrictive muffler.

Are you turning the bike on (not starting) after you plugged the power tuner in?
