Thank you but isnt Target Tune more hardware I have to buy?

Surprise. I mailed my first PV to Dynojet for an evaluation . It is OUT of warranty and was prepared to pay to fix it if possible. Dynojet informed me they are sending me a new one at no charge.
I trade the bike it was married to , my plan was to have it fix and give it to the person that purchased the bike. He is in for an early Christmas present.
Not often you see this today from companies.

 

Its better to take care of a customer and create good feelings than it is to be hard lined about things. Nice to know that they take care of people so well.
Thanks
Glen

 

If I recall, it is about a $400 add to a basic Power Vision. About the price of one dyno tune.

PV-2 with Target Tune is $815

 

About two hours after I talked with them on the phone the FEDEX truck dropped off the new one. How is that for timing

 

Glen, welcome to HDforums and congrats on the PV and obviously doing a lot of reading.

Tell us what year bike and what mods you have. Sometimes it's good to know that stuff. The old Dynojet Logtuner, is unsupported, and apparently doesn't work on the new bikes. I'm not sure what year it doesn't work on, it works on my 07, but even then only with being able to use a simple txt editor to edit a couple lines in the code. It's simple but it intimidates people.


...anyway, I'm not sure about what log tuner you are talking about, or "My Tuner". How did you adjust timing?

I've never used "My Tuner". But, the other thing to consider is simply running the bike while logging and then use a combination of what you are seeing in the log spreadsheet and Quick Tune on the PV to tweak the timing where necessary.

Logging a simple CSV file, and then opening in the spreadsheet program of your choice, Excell is most common but I use an Open Source program LibreOffice Calc, it works just as well and is free.

Using the logging and a spreadsheet you will be able to determine if you have areas that have any significant detonation (spark knock events), what RPMs / Throttle Position etc these events occur at. One thing you can do is retard the timing at these cells and around these cells to eliminate any spark knock. Or, use quick tune to do the same and try to eliminate it. Also, conversely, you could use quick tune to advance timing slightly, either globally or low/medium or high range, and then log some more and see if you are getting more grunt with a butt dyno, but also log to make sure you haven't induced spark knock. Eliniation spark knock is sometimes a matter of tweaking AFR and Timing or some combinations.

Either way, tweaking timing to maximize the potential for more power is a possible exercise but only to be done in small quantities, and only after you've already done ATs and got any other pinging or decel popping out of the way.

PS I'm just repeating some of what I've learned and I am by no means a tuning expert. There are many variables to beyond timing and understanding how they all play together is a life's work, and that is why tuners like Jaime and FuelMoto and others provide such a value add. For everyone one of those canned maps he provides he has been down that path of tweaking all of those tables to maximize your bang for the buck. If you got your tune from FM or another good source, think twice before going too far off course.

I am fairly strong at working in Excel. I do a fair amount of proof of concept for tuning companies using excel. I gave up using it in favor of MegaLogViewer HD years ago for 99.9% of the engine trouble shooting. MLV is simply way easier to get to an answer as it was designed as an engine data analysis software from day one.

 

I guess I should get motivated to learning the MegalogViewer you mentioned. If I dare say so though, I think I've seen some of the charts you've published and they looked somewhat beyond brain surgery and rocket science.

Do you think they are fairly user friendly once one plays with them a bit?

 

I have settings files for looking at Harley logs. That gets you thru 1/2 the battle.... At least. I will be happy to help you thru the learning curve.
