    Go to the fuel pressure tab and make it keep the regulator closed. You will need to disable the engine over speed fault too. Have any issues let me know.

    Thats not what I found, I had to cax in a few things to have FULL fueling above 3700-3800rpm. Without the cax file I made it would only do around that mark, as many others had the same outcome.

    That video only hit 37-3800rpm which is the limit you will hit without outside changes. I was hitting that as well but if you sit on the dyno and hold a gear she will bounce off the limiter right around the same spot yours shifts at.

    I haven't had a chance to test but yes I'm looking fo full fuel north of 4k. Preferably to 5k. I didn't think this was doable within what efilive currently has mapped .

    The only other thing that i know that can be changed outside of Efi is the enabler for fuel control.

    There is another way, smarty does that but I wasnt able to figure out how but I did find a hard limiter RPM that I was able to change in the bin via a cax.

    I'm curious Mike, are you saying you can pull any MM3 you want out of the CM2100 with only EFI mapped params? Atleast until 3700rpm ish.

    The only thing I can find EFI live don't have mapped that could help is the disable bit for fuel limiters and the hard limiter for the OS. And not for sure if those are in all of the OS. I personally have not took one much over 4k as the ones I have test are customers trucks but have no issues making power to 4k. Just had a 2007 dropped off today for a tune. I will do my best to get it sorted and report back.
