PCV / Autotune / Graves

Second post! And lets get into asking dumb questions, since a quick search didn't show up what I was looking for.

My new (to me) WR250X came with a full Graves exhaust, a PCV and an (uninstalled) auto-tune unit. I'm not sure of airbox mods (yet), but my guess is they're done; I'll know once I get the tank off to install the Ecliptech Shift-I I have lying around from a previous bike that was more trouble that it was worth (*cough* KTM *COUGH*).

What's the collective wisdom of the inmates on the auto-tune. It looks like it can be set up either once, and download the map (I'll have to see if the PO dleivered the s/w or not) or connected to the map port and left to 'continuously' tune the bike. The last is appealing, especially given the altitude changes I tend to see in riding.

The Autotune module does not make real-time adjustments to fueling. It creates a log file while you're riding that you can use to adjust fueling the next time you connect your laptop to it.

You are mistaken. Check it out:
WR250R Tuning <-- linky
The AT calculates and uses the adjustments in real-time, but to make them permanent, you have to accept the trims and then they will be applied to the PCV maps. If you don't accept the trims, the AT continues to calculate new values (and applies them in real-time) each time you ride.

Interesting. I thought it ran at all times, mainly from the following quote from the Dynojet WWW site:

Quote :

The Auto Tune kit can be configured to run and correct at all times or by using the "map switch port" on the PCV. You can set it up so that you can switch back and forth between the tuning modes and the base map settings. You can also configure the Auto Tune kit to wait until the bike is at a certain operating temperature before beginning to make adjustments.

I thought it could run in two modes. First, 'store and forward', I guess, where it calculates the trims and you accept them and second as a real time programmer.

I should have said that the AT doesn't change the map until you accept the trims. The AT module is always gathering data, it just doesn't change the current map. You have to manually accept trims before they will take effect.

I spent quite a bit of time on the phone with a Dynojet rep to confirm this.

Right! Info taken in; thanks for sharing. :)
