So 1.6b - attempt #2 is coming together nicely. Some advice from the peanut gallery was applied.
1.5b settings that were rather good were
LLT 22
LLR 3-5 range
LLD 10-12 range. 12 was smokier but more responsive on the stree, 10 spool at the track cleaner and quicker
HLT 34
HLT 3-5 range
HLD 16
1.6b settings
LLT 16 (yet to be tested this afternoon)
LLR 1
LLD 8 (yet to be tested this afternoon)
HLT 44
LLR 1
HLD 16
So. Performance is the same. rattles are about the same at 1.5b. I lowered the LLT to 1 and the HLT to 10 and the rattles were still there.
So We'll chalk this up to hardware for now until I get them looked at. No point in debating until that's checked, that's logical.
So I'm going with low timing to get things spool, lots to keep things going. Running Pauls numbers, yeah, at WOT for a moment it didn't sound right at all.
So I went back to my old numbers and started to tweak. Things are much smoother
I've had lots of drive pressure differences between 1.5 and 1.6 between both 1.6b's. I'm lowering the durations to see when the drive lowers. to see if that will help lower the drive in the lower gears. I'm also opening up the gate a little too here and there to improve flow after a software change and then one more run.
So, with a HLT of 10-20 in 3rd I'd see 70-75psi drive. bump that timing up to 44, I just see 70psi of drive in 2nd, it drops to 60 in 3rd. This is over 3200rpm.
I'm starting to think durations numbers in the low teen's may be too much.

4000rpm... cant' get there... I'll give this one last shot.. with 1.5b it pulled to 3600 very good, and heck pulled to 3800 before I knew it, seem to get better ET's hitting 3600 rpm with 1.5.. but with 1.6, the power is better in the mid-range and I obviously didn't need it last time at the track. . But to help debug and get data to bob/marco here's what I go
So. 2nd gear, locked. 4x4. I floored 2nd and just held it there. the power fell fast at 3500-3600rpm and it creeped up to 3900 and just sat there with EGT's falling. My RPM limit was set to 4300. If my understand of these RPM limit is correct, then the fall off should start at 3900-4000 and creep up to 4300.
How would a stock cam in my situation lose to much HP at that RPM to not move my truck at... holly crap, that was 68mph in 2nd? LOL I never did look at the speedometer. But I'm sure it can make more then 150hp at that rpm.
