And this is a summation of cell counts from logs 0005-0008 above. It tells you which cells of the Main VE have been modified by the process and a total cell count for each. Most of the other cells are ~+6.4% from original tune. Any others were manually manipulated for smoothing.

I'm looking thru your files...

I always hook to a trailer for tuning.. it helps a ton with a turbo..
Hooked to the car hauler and loaded up a Z71 tahoe and i can pull thru the rpms slowly but at full load..

Why is it creating a canyon in the Main VE in 95kPa row? Does that mean the surrounding area is that far off?

Addition logs after recommendations from joecar:
Attachment 13764
Attachment 13765
Attachment 13766
I applied these logs and did some adjustments to untouched cells. This is what's going back in the truck:
Attachment 13767

Your log files contain 27 pid channels, this exceeds 24 pid channels, so you sampling rate will be 5 Samples/second rather than 10 S/s... this makes the data not as good (it has lower resolution).

Canyon at 95kPa: smooth down the VE table from 90kPa and up (flatten area surrounding canyon to eliminate canyon), save/flash it, and take another log.

I'm callin' it my rollin' dyno:

It's amazing how many times you guys say that and how many times it gets read but then it doesn't get checked. Thanks for repeating it again. Would be nice if tool put up a big ugly stop sign to prevent that. It's a little more obvious in V8 Scan and Tune - the graphic goes red.

This is a diff of the Main VE between the most recent tune file and the stock Main VE table (2002 Camaro).

1) If you stare at the above logs and tune file diffs long enough it looks like some values are getting lifted in the lower RPMs and may have lost some in the upper RPMs. This is what this cam is supposed to do. And, the areas that are still +~6% (from the tutorial bump) should probably be ratcheted down some more.

2) Look at the 2 cells highlighted in this diff @2800RPM and 90&95 kPa. In the last log they had counts of 150 and 99, respectively. Their values create a spike in the VE. Do I just push it back down or maybe I should stop over analyzing?

[joecar]

1) push those plateau areas down a little (you say ~6%) and roughly smooth (fill in holes, lop off spikes);

2) lop off those spikes;

take another log and post.


How is your drievability and throttle response (in OLSD) at the moment...?
