these are expensive but would make the process much easier and faster. They have different configurations available.

pmuller at fordsix has done extensive research on ideal turbo sizing for the 4.9. Would you be using a HD turbo exhaust manifold or the split EFI? I think that is your starting point.

Attached: These are not programs, just files filled with hex value FF. I'm not sure if BE uses 56k or 64k files so choose the appropriate option.

just a shot in the dark, but I would try writing a bin file full of FF from binary editor and then try writing the correct bin from tunerpro.

need some help confirming these are TV ramp timers for upshifts. I am specifically trying to locate:

TMTVRMP_12 = TV ramp time for 1-2 shift.
TMTVRMP_23 = TV ramp time for 2-3 shift.
TMTVRMP_34 = TV ramp time for 3-4 shift.

Awesome, I set the idle to 850 and timing at 13*. at 10 it hunts a bit more I think because the minimum idle timing is 10. Should I lower the minimum or leave at 13?

I'll be having it tested again in the morning. I noted that the engine needs a bit more air and fuel at idle now. Is the flame burning into the exhaust port increasing temps?

Failed emissions at idle today. Allowed is 100PPM of HC and she read 239PPM. It is a bit rumpety at idle, so it has to be the cam profile causing it. At 2500RPM, 180PPM allowed and it read 15.

Idle speed is under 700rpm so thinking I need to kick it up a bit to pass. Timing jumps around 15-25 degrees at idle. Any other help? Some have mentioned leaning it out a bit but not sure how to force OL at idle.

try writing the tune with key on engine off

Yeah, I found an old one from my 4.9 but it would have to be modified to mount up correctly. I'll just run the stock regulator for now.

ok thanks man, I was not able to find anything other than stock pressure searching around.
