Re: TunerPro RT corrupted tune

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.

Re: TunerPro RT corrupted tune

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.

Re: A1C XDF Additions

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.

Code: Select all

84fa: 26,f4,01            timer 26,   1f4, 
84fd: 26,f6,01            timer 26,   1f6, 
8500: 22,f8,01            timer 22,   1f8,

Re: 400hp 351w startup tune

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?

Re: 400hp 351w startup tune

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.

Re: 400hp 351w startup tune

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.

Re: 400hp 351w startup tune

Reviving this old dead thread. Trying to get my truck to pass Cali emissions and dude wouldn't even test it with the adjustable fuel pressure regulator. Said he's never seen one with a California EO number so I'll have to put a non-adjustable one back on and bring it back. I'm cool with that cuz I've got EO numbers for everything else but do you guys know of a 30 psi regulator that's not adjustable? I don't mind Re-tuning, should I just go to 60 psi if I can't find a 30?

Re: A1C XDF Additions

Great information. Thank you guys. Play around with reading/writing some values. Looks like like my qh is loosing kams each power off so I'll have to figure that out first.
