I have been Flashed!!

In the winter and spring of this year (2016) I debated about changing from the Honda VFR 1200 back to the Yamaha FJR 1300.  I ended up deciding to stay with the VFR 1200 and make some changes to fit what I wanted.

The latest customization has proven to be the biggest grin inducing change!  After a lot of reading and talking to a fellow VFR rider I decided to have the ECU re-flashed by Don Guhl Motors. 

It was almost time for a valve adjustment and other maintenance so I took the VFR to my mechanic.  I removed the fairings and the ECU.  While the ECU was being sent to Don the bike got a valve adjustment, new plugs and new air filter.

VFR sure looks
Time for a new filter!
The VFR's 1237cc V4 engine comes stock with 150hp at the wheel and weights 589 wet, but Honda has several restrictions on the motor.  The Don Guhl re- flash eliminates limits and raises the rev limiter by 500 rpm (if desired).

I mailed the ECU to Don with the appropriate information including what exhaust was on the VFR.  The day after he received it the re-flash was performed and the ECU ship Next Day back to me all for $375.

Once back installation was easy, but the fairings where more difficult.  Thank goodness for friends.  I got the bike home, but too late to ride that night.  The inaugural ride would come the next day.  While the bike was out of commission I also added the mounting plate for the Givi case I ordered.

The throttle response was immediately noticeable.  I was careful not to over do it and perform my first ever wheelie, several riders had experienced an unattended wheelie after the re-flash so I was wanting to avoid that.

The transition from gear to gear is now so smooth with no lag in power.  It is like I am constantly in the optimum power band.  Acceleration is immediate and produces a big smile.
The VFR and my sons ZX6R - he noticed the difference when following.
This is the first performance modification I have made on a bike and I am very happy with it.  I would without hesitation recommend Don Guhl Motors for your motorcycle's ECU reflash.  You will be smiling when you feel the power.

  1. Nice. I am glad it met or exceeded your expectations. We can be quite hesitant when it comes to bike mods.

  2. You were definitely right is saying the VFR is a looker. It is one pretty beast. Always exciting when you can squeeze a little more stuff out of the bike!
