| On April 27th of last year, I received this
e-mail in reference to first mechanical fix I made for the YCC-T (Chip
Controlled Throttle) opening rate.

I saw your video on the VMax electronic throttle workaround....BBW.
It is being linked to from an informative 09R1 throttle discussion
here:

I just thought I'd mention that *removed* are slightly ahead of the
curve on the VMax, that they (and I) have got the throttle section of
the Yamaha ECU reprogrammed and functioning with no error codes,
although the process is not quite ready for the "masses". However, I
applaud the progress you've made so far, as I originally went down a
similar path but gave up near the beginning and had no thought to
incorporate the EXUP servo for development. I'm curious about your next
step, and what your final goal will be.

Hexed Up |
And so began a
long term venture with
Garage Endeavors. After a short period of acclimating e-mail exchanges,
I anted up the ECU for our project. I have no problem admitting that until
recently, Garage Endeavors had carried most of the "Hacking" burden on
their own. I
had the pleasure of sitting front row and watch this thing unfold.
Finally, one day some data arrived. |
|
I downloaded a Hex viewer and soon I felt like the kid that got an
overcomplicated toy for Christmas. I am comfortable writing and
assembling code for MCU's, not the other way around. After hours of
searching for some guidance on the internet, I finally had to break down
and admit to the folks at Garage Endeavors that I really didn't know exactly what I was looking at.
With their help, I am
slowly learning the ropes. It is backwards from what I am accustomed too, but
this new knowledge of assembly language should prove to be handy in
future projects. I would hate to count the number of e-mails that have
transpired since the inception of this project.

| Once you get into the ECU and can adjust
it, what happens now? Study - Adjust -Test - Repeat. Not everything can be
easily defined once you are in. It takes some experimentation to fully
realize what can be adjusted inside the ECU. In this working
relationship between Garage Endeavors and myself, here is where I get a chance to
step up and bring a skill set to the table. Which brings me to my new
equipment. |

There is a new arrival at my
shop since I quit Blogging on my web site. I now own a EC 997
Factory Pro load dyno. This
dyno sports several advantages over other dyno's currently on the
market. I have upgraded the Exhaust Gas Analyzer to be a 5 gas
analyzer. Adding NOx to my repertoire will help me adjust ignition
timing to be spot on. One of the main reasons I chose this dyno was the
real time Horsepower and Torque display. This feature assures YCC-T and
part throttle fuel adjustments will be quick and easy. |
| This is also a segway to
some sad news I have to break to the V-Max community. Since I now can
measure the new V-Max's output via Factory Pro's acclaimed "TRUE Rear
Wheel Horsepower" dyno, I must relay the results are far below 173
number everyone is accustomed to. The chart to the right was a V-Max I
dyno'ed before and after installing an X pipe. |
 |
| From this point forward, I will
refer to my Factory Pro dyno results as RRWHP (Real Rear Wheel
Horsepower). A Stock 2nd Generation V-Max makes around 158 - 160 rrwhp
as indicated by the Green line in the chart to the right. Please don't
kill the messenger. |

Change. |

As per the
Garage Endeavors web site, owners of the R6 and R1 can ship their
ECU's to Jett Tuning
and have them re-flashed. I have seen several forum post asking if these guys are for real and should
they be trusted. After all,
its just some "hey who" on the internet, right? Well, from what I have
seen, if you are the type that likes to pay to have that little bit of
"extra" in your bike that few others have, you should have sent your ECU to them yesterday!
Additionally, a few forum post has
answered that question. As for the V-Max re-flash service, you will have to
contact me.
I am establishing a new web store for
Gurued Gear and plan to open it
soon. The first two items will be the jumper harness and the ECU
re-flash. I should have a good tune file done when the web store is ready.
More info such as pricing and
terms will be found there. |
| Garage Endeavors has also been tapped by
Hale Racing to handle their engine electronics needs. I
have to admit, I was not a follower of the AMA sport bike circuit until
I met these folks. Now I have set a season pass set on my TiVo and I plan on
following along with Lenny Hale and the Garage Endeavors this
race season. I hope they give 'em Hale! |
