1.)Use the required fuel calculator on the screen below to get your base numbers.
2.)Then only adjust the lower field with the "MS" next to it. If AF is getting richer with your adjustment go the other way. Essentially what you want to do is lean out the AF slowly with required fuel field. Then jump back to your VE map and add fuel.
3.) Keep at this until you get at least 1 on your injector MS gauge. This should allow the injector to run at a high enough pulse width to give you a steady idle.
Thats what I did anyway, not saying it's the best method. I started playing with MS a couple weeks ago.
Third gauge to the right is the injector PW. You want that greater than 1, closer to 2 is better. What is yours at now when it tries to idle.

Verdad Gallardo First screen is with req fuel at 5.3 second screen is with it at 3.15 1.58ms I cant adjust just the ms in req fuel. Don't know if this is because of newer version of tunerstudio. Thanks for advice will keep trying
you cant change your Required fuel MS number at all?
thats why you are having trouble for sure
your Pulse width is the same as the injector dead time.
dead time basically means how long it takes the injector to open and close
so you are trying to run the injector at the same opening closing rate as its "refresh rate" basically causing it to sputter and loose resolution
you need to change that MS value even if you load a new project or something in there. and start over.

Yes I can change it. I just cant change the lower ms number by itself. If I go to 3.15 top it becomes 1.58 lower. As I lower the required fuel rate it doesn't change the A/F enough to be noticed. Basically I copied your fairmont tune for gas and outside of it running rich as hell on the A/F it doesnt have a stumble or anything acting crazy in the idle. I bought these injectors as EBAY items new and just seem to believe that something is amiss by the gauge even with it working. I cant get this site to upload picture so that is why I have the attachment instead. Thanks for bearing with me on this as I am sure that you are perplexed as much as I am.
Well changed everything all around with new tune and new required fuel and am still getting the same old story. Doesnt matter what I change I still end up with 11.1 A/F SO if someone thinks of something still all ears.
Have you tried lowering the dead time on the injectors? I know you have them set to what they SHOULD be, but I have had to play around a bit with these settings before on cars. If you have it at 1.20 maybe try backing it down to .90 or .85 or something.
I have had them set at 1.30 where they seem to work the best and when I try to go to as low as 1.15 the motor wont stay running and it won't start. If I leave the base pressure at 50 the motor surges like it has a huge blower on it and will eventually die so i have had to lower it to 40. Thanks
