Current BD RG turbo numbers
50 psi fuel pressure just above idle. --EDIT - discoverd 3-6-10 that my fuel pressure drops to 43psi at higher boost, so these numbers won't be useful for anyone - time to fix it.--
-------Low Mid Hi
PSI L 9 33 43
PSI H 15 25 52
others are zeroes unless noted
3000 Low -4
5000 Low-2
6700 Mid 2
7800 Mid 20
8600 Mid 22
Exv 9 140 RPM=On 5500-7550
I didn't mess with these settings, but they are:
ACEL AL DR SN=8
DCEL DR=5 SN=10
I was getting a lean miss/bog at 7900-8000 mid EGT's 1250-1280.
EGT's got hotter as I added fuel initially (1380 for a second on one pull), so I figure it was REALLY lean for some reason. EGT's finally cooled off to 1250 when I got to 18, so added 2 more & it ran awesome.
I got all the hot spots out of the low & mid 5000-7000 range while playing with the EXV setting on my cruise back to the trailer.
I tried to look at my fuel pressure a couple times while at 9lbs of boost, but that little gauge was hard to read while moving. I'm pretty sure the pressure was still around 50 lbs. The fuel pressure should go up 1 pound for every pound of boost right? I'll have to try & look at that next trip out more closely.
I'm really pleased with the way it is running now, but I haven't been able to do any tuning in the HI range.
I still have BigHoe's numbers from a few posts back saved in map3, but my midrange was so lean (for some reason?), that I didn't want to risk loading that map.
It's really close now, so I think I'll get it dialed the rest of the way in pretty quickly next trip, but I'm all ears if anyone has suggestions.
