R1 Graves file. Posts: 10Verified User

Hi all.

I am upgrading my R1 2CR 2016 to R1 BX4 2017.

I will be swapping my Yoshimura Race Alpha 3/4 exhaust to my 2017 EU model. 

My question is, I love the Graves flash so much on my 2016 can I still use (Graves Exhaust Cat Eliminator file 2CR-8591A-00 EU) on a 2017 with ECU number BX4-8591A-10.

Thanks Garry.

    Unfortunately you cannot use a 2CR file with a BX4 ECU.

    However, Graves has a cat eliminator exhaust file for a BX4-10 ECU. Why not just use that?

    Hi thanks, I did see that file although i live in England and I noticed the Graves BX4 file has US at the end.

    So is it ok to use that file in EU.?

    Thanks Garry.

    Yes, you just need to make sure that the "US Harness Config" feature is set to FALSE. This is because the ignition sequence order is different between markets.

    Garry, did it work? I want to use the same file on my EU model but im afraid to mess up the immobilizer.

    Hi, I didn’t buy the BX4 in the end, I got my hands on another 2CR with only 500 miles on the clock.
