Can anyone find it in their hearts to send me a good value file for these guys? I am almost positive the sct file is not for these injectors. And I'm man enough to admit I dont have the tuning experience required to properly dial in the values.

As an alternative to just sending me a file, I would gladly accept an explanation of how to dial them in myself :)

All I would have is the SCT value file for 42lb.

My overall tune is good, I was maxing out the stock injectors so ive been working with the SVT injectors with the values copied over directly from a SVT tune (my friend in town also has the PRP). But will be going turbo soon so i'll need these 42's.

ok thanks.

I'll start looking around for stuff related to tuning the slopes and BP. From the looks of it, it would be so easy to accidentally make adjustments to the MTF to cover up issues with the slopes or BP, and not even know you made a mistake.

Well I got them in a couple weeks ago.

using numbers I got from the lab data, I had to add as much as 6% to the upper end of my MTF to get it back to the right AFR temporarily. But, everything up to about 400 counts is still okay. So I think there is a problem with the high slope I got from the lab data.

For those that may not know why this is a bad thing, when you change injectors you should not need to change your MTF if you have the correct injector values.

The SCT file has a bit higher slopes than what I got, so that would make it run even leaner. Im going to have to modify the injector values myself so any tips on doing that?

As it turns out the value file that ships with advantage 3 is garbage for these injectors.

But I tried out an old 42lb file from advantage 2.9 on my known good MTF, and it runs great! If anyone needs the file it is posted in the injector value file thread in sct's prp forum.

Well im getting down to tuning these and im pulling some fuel from when I had the SVT injectors and my load is coming down to more realistic numbers (.96-.98 instead of 1.0-1.02). So if you have these injectors I definitely recommend the OLD sct 42lb inj value file.
