Default PCV Infomation

Looking for advice for an upcoming trip this year to hotter temperatures. I have a PCV and running map M19-009-003 which is suppose to be the stage one set up. I am afraid this is going to be to lean. What map or set up are folks running in temperatures that are 100F and above. Did your auto tuner change the map much from the basic stage one?

Thanks

Regards,
Dave

i do not think that the temp diff will be enough to remap your bike.especially if it is just for a trip.

I changed quite a bit of the default autotuner map for the 106 engine, but that was all at the lower throttle/rpm settings. Not so much at the highway cruising settings. Your highway cruising range should be in the 2750 to 3250 RPM range. The stock map has 20% throttle set to 13.7 and the 40% throttle is at 13.2. If you're concerned about engine heat you could possibly richen the 20% setting to maybe 13.6 or 13.5, but you'd probably want to test that out a bit before your trip doing some longer highway runs and see how it affects your mileage. Theoritically it would run cooler at a richer setting.

The air is thinner, thus for the throttle opening/rpm it should draw less air and run richer i.e. lower air to fuel ratio.

I would think the closed loop and broadband O2 sensor would automatically adjust for that as it does in any EFI system. It might be useful to increase the maximum allowable trim value so it doesn't get choked off when it tries to compensate to achieve the target AFR.

Thanks folks for all the advise, I forgot to mention that my O2 sensors are disconnected.

Thanks

I was just about to ask since you didn't outright specify that you have an AT module hooked up to your PCV. Sounds like you don't... right?

The bike should have a temp sensor to compensate for thermal variations, PCV or not. But, a PCV with AT would probably have even more adjustment range. Regardless, you should still be ok if you're just talking about temp swing, assuming all your sensors are functioning correctly.

Now that I said that, I realize I'm just assuming vics have temp sensors as part of the EFI system... do they, guys?

Yes. There is a temp sensor. It's also part of the warm up programming. It runs for X amount of time or until the heads get to a certain programmed temp.

BBob I am really curious to see your map, and how it differs from the stage one map. Since your in hot climate in Western Arizona?
