ECU from Guhls/Dyno ready

[grover_imp]

Here is the dyno graph of the before and after ECU reflash that everyone has been asking for.

This bike was totally stock except for the slip-on muffler. The muffler was installed for both dyno runs, so the difference is only the ECU reflash.

Let us know if you have any questions.
Thanks,

IMO this is a pretty awesome result. The raw #s may not be super impressive, but it's great to see those solid gains across the entire rev range.

Don, thanks for posting and welcome to the forum!!

From your experience, how would these results be impacted by using an exhaust system that eliminates the catalytic converter? Is that something you're able to intelligently "guess" at, in terms of A/F ratios? Or would you need to have the bike on the dyno to get a solid result?

Thanks again!!
