2 Wheel Dyno Works/ Flash Tune Experience and Results!

First I have to give a huge thanks to Cruizin for setting this up as well as Nels and Pat at 2 Wheel Dyno Works for taking the time to do this. It was a great experience as I have never had a bike Dyno tuned and have never been a part of the process. It was a blast. 

We learned a lot about the bike and Nels worked his magic as always to provide a fantastic addition to this bike.

First thing when I showed up we got the bike right on the dyno and did some baseline runs.





First thing to note was how easy the ECU was to access versus many other bikes. Took all of one minute to get full access to.



We did the few baseline runs and could immediately see the throttle limitations Yamaha placed below 6,000RPM and above 10,000RPM. It seems this was the big difference between the Euro bikes and the US bikes. The bike made right around 133hp and 74ft-lbs. 

Next Nels flashed the unrestricted map and we ran it again. This seemed to immediately add the power back in the bottom as well as on top resulting in 144hp. Once Nels dove deeper into the map though he noted it LOOKED as if they replaced the ignition map in the lower RPM range with the one from an R1...

From this point Nels disabled all the junk (I will let him detail out all the specifics) and began his custom tune. He was very meticulous and very professional. It was great to see my bike in such awesome hands. One thing to note was after disabling the O2 sensors in the flash they still seemed to be messing with AFR while he was tuning. He said he has seen this before so we removed the O2 sensors completely and ran some more. All the issues were fixed. We ended up at around 144hp and the curves looked much better.



At this point we were very pleased and we rode it around the parking lot some and right away the smoothness of the throttle was apparent versus stock. This was my biggest gripe on my bike. Then we started looking around and he said he had a Hindle exhaust which he loves for the R1 and I said "you know, I hear the R1 stuff should fit with a little modification!" He was as excited as me and we began tearing my bike apart. 



Now the sound is amazing, fit is not bad at all I just need to make a slightly different bracket link for the muffler mount but we went back to the dyno. This is where we made a big discovery. The first run looked very similar numbers-wise to our best stock run and we both were surprised. After further discussion we THINK the stock cat is designed so similar to the R1 that it actually is over designed for the FZ-10 and does not seem to be a huge restriction. Granted, eliminating it has other great benefits like weight savings and heat reduction but the numbers didn't shoot up like we expected. That was only part of the story though. 

Right away we noticed the large fireballs the bike was shooting and again in came Nels' wisdom. He said he has also seen this before where in the ECU the AIS is disabled but the valve cannot actually hold itself shut correctly. We wanted to do the block off plates but it was getting late so we just plugged the airbox line for now and away went the fireballs. 

The tuning continued and man does the bike sound like an absolute beast now with the Hindle system!



Here is our final run tuned for exhaust versus bone stock. The gains are obviously across the board but the big thing going to the open exhaust was the addition 5-6hp we picked up in the 5-6000RPM range. Again there were gains on top as well but the low end benefited the most. 

My experience was fantastic and now I need to put in time on the bike to really evaluate if we need to do any tweaking. It was late last night on my ride home and Seattle traffic was as bad as always but I can tell you, it is a complete animal now. No dips in power, constant pull, the throttle is soooo much smoother...so smooth I can even ride in B Mode now which was not he case before. The bike runs amazing, sounds amazing and I eliminated a bunch of junk that I no longer need so weight savings is always nice. I will be reporting back and hopefully getting some good riding videos as long as our weather stays decent.

I cannot recommend 2wheeldynoworks enough, all the guys there are great and I will definitely be going back as a return customer beyond the ECU flashing!
