Another PV question about auto tune

My problem is I just havent played with the PV that much. When Fuel Moto sends a Map I can download it or if they send me one thru the internet I can do that. I recently just started doing auto tunes. I went out and got my PV and just hooked it up to the computer. I went in under fual and looked at the AFR tables from the original tune from Fual Moto and my second Auto Tune and they looked the same. Maybe I'm not looking or doing something right ??

You are correct. The AFR will not change. You can richer it up a bit though if you want. What changes is the VE tables. Load your auto tune map the hit the "load compare" button. This is where you will load your FM base map. You can now hit the "delta" button and see where changes were made with auto tune. If you feel it ran better with the base map and was cooler I would just load the fm base map again. If your mileage is low to mid 30s with base map I'd say it's running too rich and the auto tune is working correctly.

I too was under the impression/belief that richening the AFR mix would help decrease heat. When I started asking real experts the answer I got was quite different and none felt that any tuning would significantly decrease heat.
The AFR table works in conjunction with the closed loop bias table. Remember wherever you see 14.6 in the AFR table all that says is the firmware points to the Closed Loop Bias table, for the right mix. The CLB from FM is typically set at 700 which is quite rich. I think stock it's set to 480 or something like that. So check your clb table, chances are you are already set there for 700.
Getting the VEs right, which is what you do with Autotunes, sets you're tune up to properly get those AFRs set properly for the mods you've made to the right fuel mix based on the AFR and CLB tables.
There are also adjustments you can make in other tables, like decel enleanment and the AFR table for decel popping etc.
If you want to get more sophisticated with your tune, you can then use the Logtuner software to fine tune your Spark tables to minimize/eliminate any spark knock. Basic stage 1 bikes with no major timing mods don't usually require this. But once you get familiar with the PV it's tough to stop tinkering.
Do you know what you are running for oil temp and engine temp in typical riding conditions? The PV guages will give you your Engine Temps.

Did you update your Win PV program first. I had to before I could see anything. Assuming you"re running Windows click on the Windows icon in the lower left of the home screen. Type "PV" in the search box (without the "s) You should see "PV Client Update" appear. Click on that and make sure you have the latest version.

Ah! thanks for the correction on that, it's straight Lamda.
I think the point I was making stands though: setting the mix richer isn't going to have significant effect on the engine temp/heat.
The stage 1 and de-catting, plus a decent oil cooler and a proper tune should bring the heat down acceptable temps.
