just got one from fuel moto with there custom map and after doing download it asked if i want to reset learned fuel trim values do i say yes or no
Its not a big deal, if you do it the ECM will "re-learn" its observed values over time, if you have new parts (ac, pipes), would probably be a good idea.
On my first download I just did exhaust and a/c, I said NO.
When I did my cam upgrade I said YES.
Im thinking it may be better to hit yes and just let it relearn with the new map.
did the same to my 2012 street glide and had the same question. I called fuel moto on friday and they said to say "yes" to relearning the existing values.
I had the same question. I called Keith the next day, he said to reset the values so I reconnected the power vision and re-installed the fuel moto map and selected the reset option.
If your AFR table is changing you will want to hit yes and since you installed a new FM map I would be willing to bet that the AFR table has indead changed.
If you hit yes, should you keep the PCV on the bike for awhile? How many miles does it take to get a good idea of the new values?
Keeping the Power Vision on the bike is really only for monitoring or doing a logging run if you want to change your map. The ECM is what learns the trim values.
