ECUnleashed improved power and fuel economy?!

After one full gas tank after sending my 2006 Yamaha FZ1 ECU out to ECUnleashed for them to do their magic, I am a bit perplexed.

The power delivery is so much smoother (Yay!) and increased, especially in lower gears and mid-range RPMs. Because of these traits I and because it’s like a new bike I have been riding it much harder than I had been. I’ve been revving it out much more in first and second gear and enjoying the mid-range acceleration on the highway. How is it then, that I achieved a 2.5 MPG increase over what I was getting prior to the reflash?

This last tank I averaged 44.13 MPG over 3.465 gallons. I used to get somewhere between 41.5 and 42.5 MPG on a regular basis.

In related news, I finally settled on the best way to track my MPG. I was struggling with spreadsheets on my iPhone and also the MPG tracker apps require you to log your odometer ever single time otherwise the calculations break. Since I reset my TripMeter with every fill up I wanted to enter my miles and gallons and then have it calculate my tank MPG and my average MPG over however many tanks I had entered into the ‘spreadsheet’. Well, today I created a simple Google Form and bookmarked it on the iPhone. This makes entering a breeze since there are only two basic fields in the form. I then set up the calculation columns in the resulting spreadsheet.

Yes, the average figures are not presented to me on the form, however it is much easier to view a spreadsheet on the iPhone than it is to edit it and this setup allows me to do just that.

I will continue to track my MPG to see if this is true. But if it is, it would seem that the ECUnleashed reflash was almost too good to be true.

  1. Hi Jeremy!
    I read your posts about the FCE and the ECU unleashing procedure on your bike.
    I have also an FZ-1 (2006), with the same annoying experiences which you also had before, and loking for a solution…
    As i read out your words, you are more satisfied with the results from ECUnleashed, than FCE before.
    Maybe you have now more experiences with the “new bike”, would you always recommend it more than FCE?
    What was the price for this process, and did they give you warranty?
    Thank you for the answers!
    Peter

  2. Hi Peter,
    Sorry for the delay. I meant to respond last week.
    I have answered some of your questions in the comments of this post: http://jeremyblanchard.com/blahg/?p=715

    But now having had it longer, it is much better and different than what the FCE does. I’ve been wanting to put back in the FCE to see if it makes it even better but I haven’t had the time. I was actually hoping to get home a bit early today to do that but that didn’t happen.

    All in all, I enjoy the bike much more now and am tempted to keep it long term. The FZ1 is a great compromise bike that does everything pretty well. It’s not the bike I dream of but it’s the bike that fits my current needs pretty well.

    I’ll do another post once I get the FCE back in.
    Thanks for reading and happy riding.
