Default Do SEPST ever need a reboot or Similiar?
I had a 103 build done, with SE intake, Rinehart slip ons and s sepst and dyno tune done when bike was new. It ran **** the first 6k miles, but lately it seems to not pull like it used too. I also noticed a lot more heat. It never really ran all that hot. Even now with the lower air temps it still runs hotter than normal. So I am wondering if something happened to the software on the ecm? and the bij]ke has gone back to a stock state? I recently installed a new tssm, but the problems started well after that install and I am not sure that should have anything to do with it. The dealer that dyno'd it is too far away fro me to go there now and all the local dealer does not have a dyno up and running. Beside I really don't want to pay to have it re dyno'd. Anyone have any ideas? Can I get the software a cables and play with it myself with some expert guidance? Thanks guys

Wish I could help but tagging/bumping on to subscribe more then anything else as I am thinking about dropping the PCV and giving a local Indy a shot at doing a GOOD tune with my SEPST. How long or stable the SERT/SEPST tune is has been a concern of mine I've never seen addressed in here.

BTW....what is a tssm?

As the "tune" is written to flash memory, it won't change. More than likely something else did, such as one of your sensors going bad and providing inaccurate readings to the ECM.

I will have to look into that. Where should I start? 02 sensors? Anything else?

Has your bike thrown any codes. I would think if one or both of the 02 sensors were bad it would throw a code.

You could pull the O2 sensors and have a look at them. If you were running a little too rich, they could get some build-up and possibly not work as accurately as normal. I had that problem on a prior bike running a ThunderMax ECM
