Same old Andy.  He has NO data from a BT and he THINKS it is the same because a four cylinder car does it?  This thread is about a DIYer doing WOT, and Mayor, I AM sure we could have another thread to discuss tuning that NO FRIGGING BODY does in the real world on a Harley.  You and Keith wouldn't allow a thread to drift like this.....

The OP is really plain, and I beg to differ enough on keeping a thread in order that I, again, am out of here for another month.  Scatter graphs is simply BS, when we are supposed to be discussing one of these three tuners with nothing else to buy, download, nor understand..... TTS, SEPST, and PV.  The units that DIYers have.....   and where exactly is the JUMP OUT moment show WHAT to change, exactly change like 3000rpm at 90 kpa?

Haven't you figured out that Andy has NO actual info to share with us?  NO tips, NO how-tos.  Nothing!!!!

Me?  I am going to stick with the dyno and the various sniffers I have and now leave this thread as being totally off point and devoid of infor to help a guy who reads the first post.  Same old crap.................  different day is all.  Everybody just sticks with what they have been saying for years....  NOTHING new, like the OP tried to start.  Scatter Graphs are pure BS, IMHO.

Don't throw baby out with bath water. Scatter graphs have there place. That is why datamaster has them.  I'm not paying $40 for one.

Yep but I haven't found a need for tuning but I do use them for diagnostics if applicable as in trends.

Andy,
What do you think of the scatter plot option in Mastertune? I believe you had an influence on Steve adding the feature.

With a 15-20 minute dm3 file.  Instead of panning through the line graph.  I plot MAP, RPM, Spark Event.  Helps with roll on as well.

Here is the sample Spark Data from TTS.  We can clearly see pinging at 3500 WOT.  When you see all red.  Your good.

I never really saw much need for the scatter graphs but since the software graphing program we use inside DataMaster already had it all there we just turned them on. Kind of funny that the same graphing program is used in MLVHD, Solidworks and many other programs that use graphing, so its a store bought product that you buy and add to your program. There are hundreds of features in it that can be used but at some point you say let's just pick the ones that would be useful. Andy got people asking enough about it several years back so that's when we turned them on. Once we did that, we have never had anyone ask about them again!

Just wait and see what happens when you use a CAN base bike that gives a REAL 40 frames per second of data to a scatter plot!

The reason that people don't ask questions is possibly that most of the valuable data you use in scatter plots are hidden in TTS SW.

Hey Andy.  What kind of discount do we as CVO forum members get?  It was explained to me very clearly when I first started really posting here that in order to mention my shop or sell anything.  I had to become a vender.

I don't have any ties to that company.  I just happen to be one of his "power users".  Several ideas that I have proved out in Excel have made it into the code over the years but that has happened with several other companies.  Any more, all sorts of beta tuning devices show up on my desk for testing and to help develop tuning methods for new devices.

That is the fun part of tuning.  Simply look at the data and figure out what needs to be added to dial the device in.  I have prototype EFI stuff on my jetski right now from two competitors that both know about the other.  They both know I call it like I see it and both get better as a result.  They also both have lots of confidence in their products.

It's like verifying a TTS tune with a PowerVision with wideband.

Better yet if you see actions like that use the "report to moderator" button and that will provide a link to the post in question.

I respectfully disagree.

Its more like using an aftermarket broadband O2 system to verify a Delphi EFI closed loop system calibrated to a specific set of build and exhaust variables.

I don't get it....  Don't you guys selling dyno time do that all the time?
