With that info in mind, it appears to me that my HD tune is waaaay leaner, i.e. better MPGs, than the Dynojet tune, with much less power in higher RPMs. Am I reading the tables correctly?
So, I thought I wasn't gonna learn, but I had lots of time on my hands today while the wife and kids played with all their new toys.
I compared my original HD tune Lambda to the PV Tune I downloaded based on Dynojet's recommendation for my setup. As I understand what I've read so far, values closer to 1 (.999) are better for fuel economy and values futher from 1 increase power - stop me here if I'm wrong.

Thanks for helping me with my first steps.

I have a stupid question... If I run a datalog and pull over and stop if I use the start/run switch instead of the Ign switch will I be able to save the log and export it when I turn the Start/Run switch back on as the P/V doesn't go off that way..??? So could I jus pull over and kill the motor with the S/R switch and save it when I turn it back on or should I save it and shut it down with the Ign Sw ??..

I definetly do not think this is a dumb question, but here is what I think after looking over the autotune process: I do not think you will lose any of your autotune run(s) by turning off the Ignition Switch or the Run/Off switch. You should still be able to use the Autotune info that was automatically saved by using the Export Learned selection. The only way I see to lose your Autotune data is use the Reset Learned selection.
See...That's EXACTLY what I did..It was sitting there Idling when I stopped at a clear spot after riding a while and had a really good tune map going and I accidently hit the reset learned spot instead of the export button !!..So that sucked big time!!.. I worked hard at hitting almost all the cells ...

Ok .. Here's another question...I made a good auto tune map with jus one or two cells a bit off from the others... And if I highlight just that cell in the VE tables and change it then it throws off all the rest of the numbers in the other cells.. Is that normal ??.. and then I'd have to rework all all the table all over again ?? Thanks... Len

I know Jamie has also said that every cell has an influence on the surrounding cells, so although I have not tried to change my VE map like you have tried, that may the reason you see the surrounding cells change.
Hope this helps some, I am glad to see you are getting to ride in San Antonio, still a bit cold for me in the DFW area.

bigger injectors
Im thinking of putting in bigger injectors and a 57mm throttle body on my 107. Can I just increase the injector size in the the map to match the new injectors and then tune with the wideband sensors. Or are there other parameters to consider changing before I start tuning?
Thanks...
Thanks...
