Guhl Ecu flash
- Thread starter Bam Bam
- Start date
I also had my ecu flashed by guhl. I had posted about this previously, in fact, its my only other post on this forum because it was the only thing that changed my bike enough to take the time to post about. Not to repeat myself, but it will completely change the attitude of the bike. After the flash it feels like a sportbike not just an old man's commuter. To be honest when I originally got my bike I was disapointed, I couldnt believe that an 800cc bike could be so lazy. Guhl's fixed that problem and if its now $275 like bam bam said its by far the best mod u can do for the money. To bad that waypoint had all those issues with ecunleashed and paid $450 but I think even he would agree flashing your ecu makes a hugh difference in performance. Now I just have to fix the suspension to match the new acceleration

i don't know the specifics of what they did. Here's a quote from one of the emails
"We work on each of the internal parameters of each ECU including, removing any factory restrictions (ignition and/or throttle), optimize fuel and ignition curves, deceleration maps, throttle maps, rev limit,and many more."
regarding the fuel maps, to me the fuel map they input feels lean... so even though it's not the same, i'm thinking one of the tamer stock maps will be a good place to start. i ordered a juice box pro yesterday so when it arrives i'll play around with it and let you know if any of it works. if i can't get it to where i'm happy, i'll take it to a dyno. but i've spent my mod budget of late
Word! if they had gotten the fuel map right i would be ecstatic. but even though didn't, i'm still happy with what i got for my money.I also had my ecu flashed by guhl.

Hey as far as the Dyno most shops will give you a baseline run for $50
lol. just got 4 inches of snow here so wont find out new top speed for a while. topped out at 139 with stock sprockets before guhl flash. as soon as i get some clean roads and sunshine i'll update, might have to wait till june at this rate

sorry to hear about the weather. i count my blessings everytime i head out to ride. hard to be SoCals weather for outdoor sports.
i have NOT found the new top speed... i didn't even know the stock top speed. i like to carve the canyons at a good clip but there's not many places around where i live that you could safely get up to the top speed.
that said, i'm doing a track day at willow springs big track on april 21st and i'll be able to wind her out there for sure.
also wanna say, i rode both saturday and sunday this last weekend and, now that i've really had some time with it and the new tires, i'm even happier with the flash now than before. feels like a beast now. it's a bit lean still but i just got my juice box so i can add a little fuel and get her mapped at a dyno when i get a chance.
hope your weather is on the mend

Yes the couple rides I have had on it since the flash,it is a totally different bike.Very happy with the performance now.Keep us posted on how the track day goes.It also looks like the weather is starting to come around so I cant wait got both bikes all ready for the season.
under the air box. The large red circle is the ecu it has 2 plugs. the small red circles are where the air box mounts after the lid is removed

That was my guess looking at pics. Thanks for help.
no they can customize your ecu with the fuel maps with out the need for a piggyback system like a pcv or bazzaz
Here are some links to videos of bikes don has done with Brocks performance and such.

Thought about getting my ECU flashed too....not sure if Guhl or ECU unleashed ( what is the difference between both) ...but on the other hand i bought the bike 2 months ago and have only 1600 miles on her ...and guess the warranty will be history after this mod but a bit more power would be nice

Guhl is a company that does it in house and has a one day turn around.They have a very good reputation on other forums They have flashed ecu's for both of my bikes.The started in the buisness with micro sprint cars which use the the same engines as our bikes so they know how to get power out of them.They are a small company located in eastern pa but they are known worldwide. Ecu unleashed is a middle man that sends the ecu to pasini a company based in italy.Therefore you have at least a week turn around.
Guhl flash $275
Ecu unleashed is $499
Pasini also owned the company dynatronics which i recomend doing some reserch on they where know for ruining ecu's and having terrible custumer service.

on the warranty you might want to check because I know guhls has several bike shops around that offer the flash as an option with a new bike and guhl does not imprint the ecu just a sticker so there would be no way a dealer could tell the parameters and encoding was changed. Lets face it most dealer techs are real yoyo's
here, if I go with the option of not modding my stock fuel map, can I still use a pcv to upload my own map? and someone mentioned that previous maps won't work because ECU is not stock...? What do you mean by that?
