Thank You Dennis. I did not know about the additions to your instructions. The Autotune Datalogger look really cool. -Dave.

I have a question that may have been answered already, but I can't seem to find it using the search function.

I found 3 different versions of how to use the log tuner to tweak your settings. One is on the Fuel Moto (Link) website, one that JustDennis (Link) created, and lastly the WinPV User Guide (Link) from the DynoJet website. My question is, which is the better version to use? There are a lot of similarities in each version, but there are also a lot of differences...especially in the WinPV user guide.

 

They all contain very similar information but serve different purposes. Here is my take on them.

The DynoJet manual is a very detailed look at the software and PV with screen captures that steps in the setup and tuning process in great detail. It tells you how to do a lot of things but doesn't really tell you why or tie them together. It is intended as a reference manual for the PV and software. Many times it tells you all the things you can do but not why they should be done or in what order. I have suggested and requested that at some point DynoJet publish a "How to tune your Harley with PV" manual.

FuelMoto's guide is more of a how to setup and do tuning guide. It is very good and has much of the material that can be found in the one I did. It is a basic setup and tuning guide.

JD Basic Instructions - I compiled this from various sources at the request of some of the folks on the forum here. It is a simple How-to guide combined with some common questions that folks here were asking. I added some Tips and Tricks along the way plus some unpublished features from DynoJet that are in Beta testing. It is an informal compilation of the information that can be found in the manual from DynoJet, the instructions from FuelMoto and the information found in this thread and others on the forum plus some information garnered from personal experience. These instructions are a work-in-progress as we find more information thru our questions here and DynoJet adds functionality to the PV.

Each of these has its own usage and folks have found each of them helpful. I would recommend that you use the DynoJet Manual to become familiar with WinPV, Log Tuner and the PV, use the information from FuelMoto for initial install and setup and read the instructions I wrote to help summarize the tuning process along with tips and tricks to help with tuning.

Hope that helps. If you have any specific questions, someone here is sure to help.

 

Dennis,
If you log "extra" channels in addition to the channels needed by the logtuner software, does it affect logtuner results or does logtuner just ignore the additional channels?

Also, I noticed on your new instructions that VE front and rear are needed for later versions of logtuner. I am using the newest version of logtuner on the DJ website. Does that mean that I need to Add VE front/rear to my signals list in addition to the 11 signals that I am already logging?

 

Log Tuner will ignore the information it doesn't need. I normally try to keep my tuner logs pretty slim - meaning just include what LT needs. It makes it easier for me to review and the files are a little smaller but extra fields don't hurt anything. Once I get a tune in place, I will add other fields to the data log so I can review how everything is working together.

Some folks have reported that if VE front and Rear are not included in the datalog that Log Tuner will not generate VE changes. I have verified that as true working with some of the folks and DynoJet. I have not received a definite answer on when you need them but have determined that in some instances VE Front and Rear are required. It doesn't hurt to add them in and for some calibrations/combinations Log Tuner seems to need them to work.

If you are getting VE changes with the log data you are using, you can continue. If you stop getting VE changes, add VE Front and Rear and see if that resolves the issues. Or you can add the channels to what you are logging, it seems that DJ is using that information in some circumstances.

 

here is my 2c... you can add many items to log and log tuner will only take what it is required to update the VE tables and to what Logtuner requires... you can look at the logs with EXCEL and for your curiousity to what is happening at that instant of time and condition to help u understand more what is going on with your scoot.

 

At one point I had a 17 mb spreadsheet in Excel to bit bang down a tune to auto generate the next set of VEs to try. It work great. MegaLogViewer HD obsoleted my Excel program overnight when the scatter graphs came on line.

1.Is it unusual to only have a 2MB log file after a 30 minute test ride? I read everyone else's comments on how they are getting 10-20MB logs and I wonder if I am missing something. I know I added all the Datalog signals that are required for log tuner in addition to a few more...both log runs that I created are around 2mb.

2. When using the 319245 code, does it log all of the required signals for logtuner to calculate a new value file? And is there any advantage to using the code over manual entry of the signals?

3 The following is from the Fuel Moto instructions:
"PV Log Tuner uses only certain data and also has specific filters, however for the quickest results it is recommended that you disable Accelerator Enrichment, Decel Enleanment, and PE Fuel during the log tuning process. To disable AE and DE you can go right to the AE/DE Multipliers and change them to 0, and for PE set the PE Enable RPM above 6200"

Are these changes made to the calibration then flashed to the ECM prior to data logging, or are these changes only made to the calibration stored on the computer and then reset prior to copying to the PV for flashing?

Sorry in advance if these were already answered in prior posts.


PS. Thanks for the answers and help Dennis

 

Does this have to be done while hooked up to the bike? Can it be set using the WinPV software the same way you can assign signals to the unit while hooked to the computer?

Is the code remembered by the unit or does it need to be reentered each time you plug the unit in to the bike or each time you start a new log?
