Guess I'm gonna have to hook the laptop up and fiqure out how to look at TPS reading. All I did was install the PCV, download V&H map, used the supplied connector instead of soldering into the ecm wire then buttened it up.

Is there a good ground fix, how to do thread around here?

Look into fxstein's Blog, he found and investigated the Issue and also wrote a good Write up.

Basically, it's cutting the smaller Wire off the PCV Ground Connector and connecting it to the Sensor-Ground Wire on the Bike, which is Brown/Black Color Code.


Regarding the the Autotune, i think it's the most misunderstood Product of the last three Years.

Everybody believes all the Autotune does is to produce a Correction Table to the existing Map in the PCV.

That is wrong.

Autotune does regulate the Injection Times to the set Target Map immediately when activated. As an Byproduct, it does create Values in the Correction Table which can be computed into the Base Map by accepting the Trims. But the Main Thing is the REGULATION PART. This is wrongly, or better said, not completely advertised or communicated by Dyna.

So, the Main Task of the User is to built up a perfect Target Map for your Bike and Setup. You'll be a very satisfied Customer and can let it run activated forever, because Autotune will correct every Influence on the Fly, based on the Target Map. You never have to accept the Trims and fill your Base Map with senseless Values created under Decell, which is not the Fault of the System, but just plain Physics.

I.e. i built up a Fuel Saving Map and used it as my Base Map. When i want Power, i activate the Autotune and it will correct the Injection Times to the Values i entered for having Power(like 12.5 to 12.8 AFR) in the Target Map. The only Problem is, you have to check the LSU 4.2 Sensor for Accuracy once in a while, because the Sensor degrades rather fast, and you could need a new one as early as within a Year.

My TPS is not going as crazy as the one video that's posted somewhere on this site but it's not rock solid either.

Fxstein's Blog is not the greatest explaination to get it done. I like going to resturants that have pictures in the menu, if ya know what I mean.

Does the TPS mod helps the signal at low rpm cruising speed and will make the bike run better at light throttle inputs???

I'm getting a minor fumble

Sure it will help at low Speed, the TPS Voltage is around 1.0 Volt and the "Noise" on the Signal is a Lot more pronounced than at full Throttle(which is around 4.2 Volts).

The Hicc-up around 2800 RpM will still be there, it's coming out of the ECU, but can be minimized with the PCV.

Disclaimer: I work for Bazzaz and am here representing the product.

Wow. A few things to cover. Glad I got here!

First, the 'Autotune' is a decent attempt to replicate the original Bazzaz 'Z-AFM' self mapper. The invention of the self mapping module was in 2007 by Bazzaz, based on the race data analysis of Ammar Bazzaz while working as Mat Mladin's crew chief. The algorithms used are very much race proven and superior to what is otherwise available.

The other big difference is the way it collects and applies the data. The Z-AFM is not closed loop, so it is not trying constantly make changes based on info from a throttle/RPM combo that has just passed. We felt that a singularly closed system is too reactive. With the Z-AFM, the data is collected while riding. After doing so, plug in via USB, view the recommended changes, and simply click a button to apply them to your base map. Your bike now has a map and is ready with the changes to act. We find it more responsive this way.

It also has a more rapid data processor.

Finally, the Bazzaz Z-AFM also maps below 20% throttle! 0 - 100%

Hey Bazzaz, just went on your website and noticed the Vmax photo is not a Vmax, may turn some potential buyers off, just thought I'd let you know.

I mentioned it here and a couple other places before, but I will bring it up again. I will offer the option of leaving the AIS signal operational on the second version of the re-flash. I found the AIS signal is a wonderful point to hook up a start/stop interface for the learning mode of the PCV. The AIS signal is ON during any throttle advance or cruise and goes OFF at any slight decel or throttle closing. This will trim ALL bad decel data from what the Auto Tune averages.

Good explanation, BTW.

Got a used PC and Autotune for anyone interested!
