What happens if a stage 1 is done without a dyno?

What about the "no download" mode? There are no canned maps for 95", 10:1 CR, Fatcat, TW54 cams and ported heads, or any number of displacement and performance configurations. It can take several hours and 50-60 pulls to dial in a performance configuration. The tuner earns his money and has to know what he is doing.

I know this doesn't apply to a Stage I upgrade but the SERT is a very good tuning device, just not real user friendly for high performance configurations. The TTS Mastertune is as good or better and much more user friendly.

The new SEST software listed in the 2010 SE Parts catalog has a new feature called Smart Tune. Reportedly you load a canned map close to your configuration, log a data run and the software suggests alterations based on your desires for optimizing best power, economy, etc. Supposedly the MoCo's answer to the Autotune devices out there and avoiding repeated dyno pulls. S'posed to come with every canned map back to '02 as well as a variety of Lambda based maps for the 2010s.

I'll be looking at the software and instructional DVD in a few days..... no telling whether the MoCo has got it right yet but those I know family with it think it's the best thing since sliced bread. We'll see.

One thing about Dyno tuning...while getting the most out of your new '09 machine is a very good thing, the downside is repeated runs on stock new engine with Wide-Full-Open throttle for a few minutes 10 times or so does not help longivity. The onas is on the dealer to get it right with as few runs as possible...with the necessary tools in hand. Going back and forth Dyno-tuning seems counterproductive and not my idea of good service from "factory trained specialists." And not having canned programs is just an excuse, testing bikes all over the country over a computer network?...hmmm JMHO

hmmmmm smart tune is it likely to be retro fitable to the older software HMMMMMMM i doubt it :(

I have heard that a similar feature is in the works for the TTS Mastertune and the SERT. Some SERT's qualify for an upgrade to TTS Mastertune; if qualified, the upgrade cost is $100,

Pg 21 of the SE Parts catalog, it comes with cals for '02 to '09 as well as the new Lambda based cals for the '10s. Dunno if you can update the old software but it appears the new software is backward compatible with previous Tuners.
