So any changes to spark advance using auto tune basic in the past are 4* too far retarted?

 

For immediate release:

Automated tuning is now available, for full info, screenshots and the latest beta firmware as of 9/18 you can go to http://blogs.dynojet.com/index.php/2...now-a-reality/

Dynojet has already left the competition in the dust with its innovative Power Vision flashing tuning system for fuel injected Harley-Davidson motorcycles. Power Vision supports ALL Delphi ECM equipped Harleys, offers the most tunes for popular aftermarket parts, includes exclusive features not available anywhere at any price, and now an embedded auto-tuning technology that makes tuning your bike easier than ever.

The new Autotune technology leverages years of dyno testing and tuning directly into the Power Vision. The process is automated, fast, and best of all you reap the benefits of technology in the form of a refined, powerful tune! Power Vision can utilize one of two different methods to automatically tune your bike; the Autotune Basic method that uses your OEM narrowband sensors or Autotune Pro that uses wideband o2 sensors from Dynojet’s Autotune wideband control module. The entire process is handled by the Power Vision (setting up the tune, logging data, fixing the tune, and flashing the tune) which means that you don’t need to fumble around with a computer in order to realize professional results.

Awesome! Autotune Basic has worked wonders for my bike! The one thing that I would recommend adding to the blog is to mention that you need to flash the ECM with the new saved tune

 

I see that the "Quicktune" capability isn't shown on the main screen. Does that mean it can only be accessed by enterring the code?

 

Will the auto tune basic adjust the spark knock events and make changes and will I still be able to tune manually if I choose to?

 

PV Beta instructions states that :
"Downloaded tunes that have a note that says, “PC Import” are not recommended for use with the Autotune process. Although these can be used, it may result in excessively longer periods of learning."

There is no tune other than "PC Import" for my 2008 FLHRCI, whatever air filter, exhaust etc...
Mine has Jackpot 4" dynotuned mufflers and Screaming Eagle air filter.

Has someone a tune that could be a good starter ?
If not should I go from my stock ?

Thanks...

 

All my links to the Beta 1184 are not active.

 

This is in the other forum. quote jamie fuel moto I dont think he will mind copy past info here.


"There are a couple ways you can review your data. PV stores the base .pvv file as well as the new "corrected" .pvv which can be retrieved in WinPv by going to Get Log. Also, when you are on the Auto Logger (green) screen you can start/stop logs to simply review or you can use them in PV Log Tuner software if you would like correct your tunes "the old fashioned way" rather than exporting your corrections right on the PV display".

 

I just checked the links and they appear to be "up and running".

 

It's not recommended to use the "Autotune Spark" provision in AT-Basic. As you know, when you select AT-Basic there are various changes made to the tune prior to flashing it to the ECM, one of which is to retard 4 degrees of timing (in an attempt to help the bike "tolerate" being run at stoich / 14.6 AFR).

Even if you nailed down the fuel side of the equation and then wanted to focus exclusively on spark corrections, it's really not fair.....so to speak. So lets say you set the Max_VE_Learn to .01 (if you set to 0 in AT-Basic it effectively shuts off the ENTIRE AT process....fuel and spark, no matter what the other settings are) in order to minimize any changes to fuel, and then set Max_Spark_Learn to 10, you would be recording / correcting spark based on knock activity. The reason I say this is not fair is because the AT-Basic process "set up" the tune that was flashed, and remember the AFR (or lambda) table is set to 14.6 (lambda 1). The amount of knock activity recorded *may not* be present at richer AFR's, which you most likely have defined in your tune (or the tune you'll end up running with) at higher loads / rpm's. Your engine can technically tolerate more spark advance at richer AFR's given the same load condition.

So, even if you temporarily advanced your base tune by 4 degrees, did process above (which again pulls 4 degrees, so now during your AT-Basic process you're running your normal spark tables), and then let AT fix up your spark tables, and then remove the 4 degrees you temporarily added....well....it's just not ideal because you're still running around at stoich during this process.

This is not an issue with AT-Pro, the spark corrections CAN be made independent of fuel, or you can do both at the same time (I recommend nailing down fuel, then address spark).

What we need is a provision for AT-Basic users to tune spark (based on knock activity) independent of fuel corrections, and without the AT-Basic process setting the AFR to stoich 14.6......like AT-Basic (Spark Only).
