For about $30 you might take a look at
MyTune software from www.tunemyharley.com
it will suggest both VE and timming table corrections using logs from your PV.

Shame you cant tune with WB 02 for the basic software
They make you pay $200 for the commercial licence to read the Wideband 02's

HI friends, I have a question about the auto tune in Power Vision.
I have a Softail Rocker C, twin cam 96 inch.

Dynojet send me a tune map for my bike for open air filter and big radius exhaust. OK, I installed this tune map and after I did three auto tunes.

When I compared the new auto tune results with the tune map from Dynojet, I saw in the first tune map in the Engine Displacement say 96, in the auto tune results, say in 102,7.
I dont know because change the engine displacement.

It's okay, if it goes up a bit like that. It is making an adjustment to the displacement in order to provide more fuel based on your VEs. Answer YES to the scale up question and then do at least a couple more Autotunes. Save the Autotunes and bring them with you back to the house, load them on your computer and use WinPV to do the "compares".

Make sure to do Compares, using WinPV from the initial ATs to the next AT, with a setting of "show delta as percent". Once you get to all the cells being within 5% of each other you have reached a state of tune to say you are complete.

PS If your PV wants to continue to scale up to higher and higher displacements and the VEs are all hitting 127 at WOT and high RPMs is an indication of the bike not getting enough fuel and you may have a fuel pump problem. I had this problem.

If you reach max. VE values of >125 you are given the option to auto-scale the max. VE's to 120 or cap the values. If you chose the scale option, before saving the file, it will scale the displacement up to correct the VE's.

You are correct. The PV will correct VE's only when running autotune basic.

That's why it's important to have a good base tune map (where the AFR's and timing have been reworked for your set-up) from a reliable source like Fuel Moto. Dynojet will supply maps, but personally I prefer Fuel Moto for both base maps and support.

I've heard you can't use Logtuner with the new bikes. But I'm not sure that's true. There is a bug in Logtuner that occured at some point for lack of ongoing software maintenance from Dynojet, but there is an easy workaround for it, if you know how to do a simple edit to a file, using any text editor.

Use these directions. and look at the added workaround at the end of the directions. Give LT a try it works great. Most will use Autotune for fuel (VEs) and then LT for timing. (Spark tables.)

Here is my Dropbox link to a doc file with the directions.


https://www.dropbox.com/s/m5vmexx40q...tions.doc?dl=0

And to underline what NH1Rider stated above you need a good base tune to start. FM being the value added preferred vendor for their excellent support and great basemaps.

Logtuner will NOT add to timing, but will identify areas that you are getting spark knock events and decrease timing.

Before i did the auto tune, I saw in youtube the videos about the auto tunes and the optiom of scale or cap when i save the tune map.
The problem, when I did the auto tune and at the moment to save, power vision dont question me about this option. Power vision saved the tune directly.

Can you look at the displacement value of the original tune? Upscaling, as NHRider1 stated, is done at the save point. It will make a statement stating there are values greater than 125 "do you want to scale up"?

If it's just one or two cells, you can make the decision to just cap. But if it's a lot of cells then scale-up would be recommended. With your build, pretty open breathing and exhaust, it doesn't surprise me that it wants to add more fuel, especially at WOT and high rpm.


PS I haven't done an autoune with the latest updates, I suppose it's posible that the PV just makes the decision for you now. But I have read anyone else mention that out here.

Did the recent updates change anything in Auto Tune? I thought the updates were more for getting things ready for Target Tune.

I had the option to scale mine. I have the 555 cam and when I had it dyno'd here in Florida, my displacement now says I have a 132.3 CI bike...haha. Runs like a beast though so I can't complain.
