using AE for data logging to get tunes dialed in?

do it in overdrive.

live life full throttle

Do you realize how fast I'd be going in overdrive at 3200 rpms! I live in n. mi there ain't a road around more than 55 mph for at least 50 miles from me.

so there is my data log in the 120 race. that's in 4th gear at rolling all the way into it at about 1400 rpm and letting out at about 3100 rpms. it looks like my ICP pressure levels out at 1900psi on this setting and injector duty cycle is at about 85% at 2700 to 3100rpms and 100% throttle. do these numbers look right? good or bad or about normal for a 150k mile engine with stock everything? thanks and this AE is fun to play around with.
for the record my truck feels very good healthy and strong even if these numbers are low.

 

[under pressure]

1900 is low, 85% is twice what you would want to see. Try a log in a DD, 80 or 100 tune in the same parameters. The pw on that big tune is probably stretched to far killing your pressure.

for comparison, my last log. stock inj,hpop

[jaybuller]

yes in the 80dd tune I have 55% DC ICP 2900 at rpms under 2700 over that the icp drops to about 2500 and duty cycle goes up to 60%
