petshark Posted June 18, 2021 Share Posted June 18, 2021 (edited) The possibility to start the bike in A mode is on many lists as a good reason to get an ECU flash. My 2019 GT always starts up in A if that is where I left it. Is this where I find out that this ECU might have been messed with by a previous owner? Or is it just the newer models that can do this?

CRFan250 Posted June 18, 2021 Share Posted June 18, 2021 (edited) My 2020 starts in A mode or whatever mode I left it in and its a stock ECU.....They must have had a programming change somewhere along the way.

lolocastsb Posted June 18, 2021 Share Posted June 18, 2021 2015 that I just bought used, starts in A mode. Can't definitely say but I'm 99% sure it's flashed. 2 Link to comment Share on other sites More sharing options...

That’s what I figured. Thanks for clearing that up. 1 Link to comment Share on other sites More sharing options...
Supporting Member texscottyd Posted June 18, 2021 Supporting Member Share Posted June 18, 2021 @petshark - The early FJ definitely defaulted to STD mode every time you started the bike, regardless of the previous selection. That changed at some point (I want to say with the 2019 Tracers?) to be a ‘sticky’ setting that retains your prior selection, regardless of mode selected. So, if your early bike (like my 2015 FJ) starts in A mode, it has definitely been flashed. On the later bikes, it doesn’t guarantee anything one way or the other. Additional caveat: This is accurate for US spec bikes, but I can’t guarantee it’s globally correct. 2 Link to comment Share on other sites More sharing options...

Nice to have, as it noticeably improves the ridability (especially smoothing out the throttle response in A Mode) Link to comment Share on other sites More sharing options...

Went to test ride my current FJ09 and the old owner insisted there was no ECU flash (he was the second owner, so it must have been the first one who did it) despite starting in A mode and being VERY responsive. needless to say I'm happy! 1 1 Link to comment Share on other sites More sharing options...
Zach26 Posted June 20, 2021 Share Posted June 20, 2021 I didn't even know this was a thing. I've used standard mode almost exclusively on my 2017 (bought new in 2019) since I don't like the abrupt throttle when going from closed to open in A mode. I have used B mode maybe twice in bad weather. I always thought that it just stayed in the mode it was in last. I guess I'll confirm for my own info in the morning.

Rick123 Posted June 20, 2021 Share Posted June 20, 2021 My 2017 starts with whatever mode I left it in. A in my case. 1 Link to comment Share on other sites More sharing options...

I was out riding with a friend who has a '16 this weekend and I noticed my '17 stayed in A-mode. He was full of envy. 1 Link to comment Share on other sites More sharing options...
