Autotune is different than you might think.
Autotune for the PV is simply the ability to use the device to log your ride.
From that log data, you can create a new map and download it to your ECM all using the device, without having to download the log file to your PC to create the map.

It allows custom AFRs at different RPMs

You can adjust the AFR for different rpms and load kpa/throttle position. There are 170 different positions. This is only when in closed loop and only one table. The way to change the mixture is to raise the Volumetric Efficiency VE to richen and lower to lean. Here there are 240 different positions on Touring models. There is a front and rear cylinder VE table. A typical cruise area VE is around mid 80's and power 100% load is around 90. The idle area is around mid 70's to mid 80's. All these are for stage 1. Throw a cam in and all these numbers are out the door. The cruise area will be close but the idle area will be 15 to 20% lower on most cams and above 2250 to 2500 load area 15 to 20% higher. These are rough numbers but if you look a the maps you will see what I am referring to.

Excellent..
What about setting the fuel trims MANUALLY, outside of just setting an AFR (just like you use to using the plain old power commander)?
Ive used the autotune before with a PC5 on numerous sport bikes, but found it annoying that the autotune only lets you run just a little leaner than 14.7:1 I think it was (maybe 15:1 dont remember).
I was able to tune the highway cruising range of a few bikes to over 50mpg, but it took a LOT of data logging and riding with a laptop strapped to the tank lol.

I have been studying and using the PV for a couple of years now and learn something new everyday about it. Have probably edited and created over 100 maps for various setups. You can mount the PV on bike and watch your instant and average fuel economy if you like. It will also monitor every function that has a signal to the ecm. Engine Temp, VE's, spark advance, spark knock, what gear you are in, rpms, %load, throttle position, and many more. You still have to watch the road so be careful. With data log it will monitor all these for you, then pull them up in Excel and see what you need.

Need to forget some of what you learned with the PCV. PV doesn't use fuel trims and no lap top needed to autotune or data log. You set the AFR on a table. Most strategies use Lambda where 1.000 is equal to 14.64 I think. The lowest (richer) the narrow band O2's will stay in closed loop is .981 or 14.36 Stoich according to the PV info. There are manuals for the Win/PV and Quicktune, and Autotune on the Dynajet web site you can download. There are also a bunch of training Videos on there also. The SEPST has a training DVD you can buy that is very helpful in learning the flash tuners. If you can use PV you are 90% of the way to being able to use the Harley tuners and TTS. They are very very similar in function. TTS will allow you to download their software and tunes for free. Harley not so much. You have to buy it. All are very good tuners. I didn't say the others aren't as I haven't used them.

Engine Temp only shows up on the PV under gauges. Once you pull it up there it will be on the Data log.

Here is map I am currently running. It is tuned to optimize fuel economy at all rpms and % load KPA. It can probably be made better, but pretty good right now. A little autotuning may help it. Note the speedo is already adjusted on this map to be accurate around 60 mph. The stock setting is 2206 and the new is 2262. the formula I used was to divide the amount off like 2mph by the speedo 60 mph reading then multiply this .03333 by the setting in PV 2206 and add this 79 number back to the setting in PV. It will get you close depending on your particular setup. Mine was off about 1.5 is the reason for the 2262. 2 mph would be 2279 I think.
