Recalibrate tuner after major work?
I just finished a cam change and exhaust header change along with a bunch of other work. I was laid up with a bum leg so I took my time. Bike hasn't been run since November. Everything is back together and I took the cast off long enough to ride around the neighborhood and check out the "new" bike. No leaks and no parts falling off. Should I recalibrate the TTS or should the bike run okay as-is? I haven't run the bike long enough or far enough to tell if the current tune is still okay and I want to be very careful about running in the new parts. Thanks for any helpful advice.

never mind
I'll answer my own question. No. ECM doesn't change by itself no matter what you do to other external parts. Only an active interface like a SERT or TTS, etc will make changes to your ECM. If you make significant changes to your engine (cam, intake , exhaust) then it may be wise to update your ECM mapping as those changes may have affected the original tuning.

The TTS will make adjustments but you have to run the Vtune process and make the changes indicated. Run it over and over until you have modified all the cells as indicated on each run.
If you don't have the TTS manual, go to the website and download it.

After major modifications the things that seem the most bothersome and the longest to sort out are the little things.
Starting-cranking fuel
IAC
warm-up
Accell enrichment--flame out
decell enleanment-- popping
very slow moving around like in congested parking lot.
There are some others I am sure.

Cam and head pipe change? Needs a new tune. Pretty straight forward and you already know it, too.
Oh.... no reason to baby it after a cam change... there are no parts to 'wear in" so to speak... Get out there and v-tune that Sucka and have at it.
Enjoy your new cam, BTW!!!
