Member Contributer RC1237V Posted March 20, 2016 Member Contributer Share Posted March 20, 2016 When I had mine all apart, I ordered up the harness ($16) for the heated grips, and used that for my USB/Voltage Gauge. Used a step drill to make the hole in the plastic. I will try to post a pic.......... I have not put the voltage gauge in yet, but it will go on the other side............

andy Posted March 21, 2016 Share Posted March 21, 2016 Thanks. I just ordered one per your advice. Link to comment Share on other sites More sharing options...
Member Contributer arrow Posted March 30, 2016 Member Contributer Share Posted March 30, 2016 I've also done the ECU reflash; I've installed it back on the bike and the first impressions are pretty good. It's also nice to see the first and second gears in the gear indicator . Link to comment Share on other sites More sharing options...
Member Contributer Rider14 Posted April 4, 2016 Member Contributer Share Posted April 4, 2016 Anyone know if Guhl will forego adding the sticker to the ECU? - Dan Link to comment Share on other sites More sharing options...
Chanmenie Posted April 4, 2016 Share Posted April 4, 2016 It's just a sticker, peel it off if you didn't like it Link to comment Share on other sites More sharing options...
Member Contributer ReadingVFR Posted April 4, 2016 Member Contributer Share Posted April 4, 2016 I think by law Don has to put the sticker on since he changed the factory settings in the ECU. Like Chanmenie said if you don't like it just peel it off. Link to comment Share on other sites More sharing options...

Jashue Posted April 10, 2016 Share Posted April 10, 2016 Has anyone dyno'd their after flashing it? I was wondering the same thing. I'm actually pretty shocked that I haven't come across any mention of quantifiable changes in reflashed bikes-- either dyno numbers or track times. It doesn't matter that much... I've seen enough positive feedback for me to have the service done. But I AM curious. Link to comment Share on other sites More sharing options...
Member Contributer luvtoleanit Posted April 11, 2016 Member Contributer Share Posted April 11, 2016 Has anyone dyno'd their after flashing it? I did, but I did the de-cat at the same time. The 1st/2nd gear restrictions are gone and my gear indicator works in every gear. The fans also turn on earlier. So everything Guhl claims is correct.

Member Contributer Dutchy Posted April 12, 2016 Member Contributer Share Posted April 12, 2016 Over on the Dutch forum an owner posted the results of 2 2010 non-DCT's put on the same bench in sequence by the same tester VFR1200F 2010 Handshift Remus exhaust no other mods 140,1 HP rear wheel VFR1200F 2010 Handshift Don Guhl Flash K&N Filter 141,6 HP rear wheel Put on top of one another, the graphs were pretty much identical he wrote. Asked if they also included torque, for that is/could be the key differentiator. Link to comment Share on other sites More sharing options...

Chanmenie Posted April 12, 2016 Share Posted April 12, 2016 I don't think so there's no way the VFR1200 makes 189 HP the 140 HP is correct its 172 BHP at the Crank and 140 at the rear wheel you can get into the high 160's with a decat, end can, air filter and fuelling module like a Power Commander Link to comment Share on other sites More sharing options...
Knight Posted April 12, 2016 Share Posted April 12, 2016 Wow did I get that wrong. I should know much better than to question Dutchy! That loss to rear wheel output just sounds huge to me. Link to comment Share on other sites More sharing options...

veeefour Posted April 12, 2016 Share Posted April 12, 2016 Something is either wrong with that bike or with the dyno. They typically make ca. 152-155 RWHP STOCK. 140 RWHP means almost 20% loss which is just not possible. Link to comment Share on other sites More sharing options...
lshark Posted April 12, 2016 Share Posted April 12, 2016 there are different standards for measuring HP.....i can't quote them off of my head but SAE is one the Guhl reflash is not about peak power but removing restrictions, mostly affecting mid range power Link to comment Share on other sites More sharing options...

crakerjac Posted April 13, 2016 Share Posted April 13, 2016 I did a couple dyno pulls after the re-flash... but not a full dyno tune. My bike made 147hp after a long group ride (so motor was not cold). Link to comment Share on other sites More sharing options...

But I agree something's not right... 140 rwhp compared to 173 crank gives exactly 19% - that would be the less efficient drive shaft I've ever seen. Even quattro torsen is more efficient...on 4 wheels. I'm talking about total system loss. More to say they use DIN in NED. 140 DIN is 138 SAE.

I read somewhere (can't remember) that the loss was only 6% off the crank. I'll try and find that source again. The VFR is supposed to have the best power change between the crank and wheel of any shafty bike. Although I don't know the newer BMW numbers yet.Sent from my SM-N910P using Tapatalk Link to comment Share on other sites More sharing options...
marriedman Posted April 17, 2016 Share Posted April 17, 2016 I just got back from a 100-ish mile jaunt this evening. My first real ride since the ecu flash. Good lord. I also need to mention that I have lost 50 lbs since last year, and 120 since buying the bike. That coupled with 1st & 2nd gear being unleashed has turned this bike into an arm straightening torque monster! I kid you not, I was laughing maniacally on some of the back roads not far from here. Honda should have sold the bike with this ecu, it literally makes this bike performance jaw dropping. Link to comment Share on other sites More sharing options...
