I am starting to do tuning runs on the Fuel Moto supplied map. For those areas that I want to adjust the VEs should I use a Lambda value of 0.981 or 1.000? As I understand it the closed loop switch is between 0.981 and 1.02, is this correct? Is there any benefit of using one value over the other - or values in between?
Either or anything in between. I selected .981 with the hopes of running a little cooler, but the jury's out on that.
why is it so that i can't open the custom map? Why should the tuner lock it?
1) He didn't want you to alter what he did to your tune - protecting himself
2) He wants more of your money to fine tune it
3) All of the above
I'd talk to the tuner and see what gives. I had the HD shop do a tune for me once and I asked for a copy of it. They did give me a copy on a USB drive, but it was for a totally different bike.

Closed loop is closed loop - the value doesn't really matter.
Guys, this may have been addressed, and may be somewhat rudimentary compared to the discussions, but I will pose my question anyway.
I installed the PV map from fuel moto. Bike is more responsive. Got rid of decel popping at first. It seems now that it's back. Not quite as bad but in the same rev range as before the tune, and only once the motor is hot.
Is it possible my ECM switched back to a stock tune? Or still needs more tuning....
Sounds like you just need to make a few adjustments. It is normal to hear more popping when it is hotter. Have you gotten your VEs set to where you want them? Multiple tuning runs across most of the map and now showing little VE changes? If so, determine what RPM range is giving you the popping and then try the following changes.
Let's say you are getting decel popping from 2200 down to about 1800. First, I would go into the Decel Enleanment setting on the map and reduce it by 20% at every temp. (so at 3 degrees F where it is 1.00 it would become .80 and so forth). Try that, if that doesn't help, go to your AFR table. The 20 KPa column is where you would be during decel. Reduce the AFR in the 20 KPa column where you are experiencing decel popping. In this example, I said between 2200 and 1800 so I would the cells in the 2500 RPM down to 1500 RPM from 14.6 to 13.7 (if you were running a closed loop map). That should correct the problem. This really wouldn't affect mpg or anything because you only hit that area during decel and for a short period of time.
Let us know if you need help. If you need help changing the map, send me a PM and I'll do it for you.
Note: I updated the PV tuning Basic document to a include section on Decel popping and a few other small updates. Click link in my sig

I'm just wondering if anyone has successfully run Power Vision software on a Mac that is running Virtual windows, etc.?
PV tech support says WinPV itself would probably run fine but they are concerned about the necessary drivers for WinPV when it needs to "talk" to the PV unit itself.
I have an old Windows machine I could rehab but hate to throw good money after bad if I don't have to.
This may have been covered but I haven't found it ...yet!
I got the PV to install on an '02 Fat Boy but when I loaded it up it said there was no VIN. I've sent an email to Mr. Daniels at Dynojet already and they should reply tomorrow.
I was trying to look at the pre-loaded tunes but I got a VIN not found error. I'm thinking this may be because there is only '06 and above but I'm not sure. I'm wondering if there is any other functions that I will not be able to use.
I don't have the O2 sensors on the exhaust BTW.
I just installed it a couple days ago and work is getting in the way, hoping to get it up and going sometime this week.
I only have free flow exhaust and air cleaner but the shop I do the web design for wanted to play with one and my bike is running lean so what the heck, right?
TIA for your comments.

Thanks.
I'm running Windows 7 in Bootcamp on a Macbook Pro and it all works fine. I boot to Windows to use it.
