Thanks! Will be a couple of days before I get to take the car out and log data.

Any issue with me adjusting the DFCO 12250? I think DFCO is coming active on coast when it shouldn't. I compared...

LS Rob, I emailed you the file because it was too big to post.

Will do! Any particular areas on the map that need to be logged?

146707 -

146708 - Started log after about 10 minutes on my way to work.

It actually hasn't bucked much before, plus its an auto and when it does buck it's above 30-35 MPH. Maybe bucking isn't the best description...more like switching ignition on/off. I'm guessing it...

Weather finally cleared up, so I loaded the new tune and captured some logs.

146665 - Cold start and cruise out of neighborhood

146666 - Main log, 25 minutes

146667 - Captured a separate log...

I try to reset the LTFTs after each flash...which is the correct process to follow or should I not?

Thanks for taking another pass and working up the tune! I'll load it up tomorrow and take a...

Loaded the tune after adjusting the MAF FAIL settings. Grabbed a log from cold start up to idle and a cruise.

146562 - Tune
146563 - Cold start log
146564 - Cruise log

Yeah, not sure what to do to take care of the fault codes. The exhaust system is Pypes 2.5" X-pipe "Race Pro" kit for Chevy II's.

Good catch on the MAF Fail...I keep forgetting to check the...

I just got back into town myself! I had done a few tweaks already and a log. I comparing the 2 tunes now...looks like I got a little more aggressive adding timing.

I'll load...

Need some help timing tables. I turned on MAF, DFCO, etc. and also copied over timing tables from a stock 2010 5.3 from a truck (less idle tables that LS Rob adjusted for me). Went for a quick run...

Have made good progress with cleaning up the VVE table...big thank you to LS Rob for the help!

Here the current tune with MAF failed - 146222

Here is a log with a couple of quick heavy throttle...

Since I couldn't post the entire log with histogram, I copied it to an .XLS to make it easy to grab. 146016

Rob, I took the car out and got a 32 minute log running the Pass1 -1.1 tune you posted. Didn't get as much of the table covered this time, but the trims are looking good!

At 4:10 in "part 2" log,...

Thanks! It's about to storm here, so I won't be out getting any more logs today. Hope to get back out tomorrow afternoon and get another log after work.

So didn't see your tune VVE Test-1 until now. I did capture a much longer log using the tune I loaded. I filled in a good portion of the table. I need to hit the higher load and higher RPM, and I...

Here is a cruise log 145956

I copied trims to tune, applying by 1/2. Smoothed and then calc coefficients. Loaded tune, cleared LT trims and back out for another drive to log.

The engine was stripped of EVAP and I have set all of those to no SES or MIL, but keeps coming back. The engine also has a fixed camshaft, have P0010 turned off as well. I try clearing the codes,...

[QUOTE=LS ROB;779187]Try this VVE test to see if it will idle.

Cranked and idled like a champ! The timing didn't fluctuate as much either.

Both snippets below are from same tune.

The first snippet the timing doesn't swing, but IPW drops to .7 and engine dies.

145945

The second snippet the engine tries to run for a few...

So I have ran into the issue again where after loading a tune the car won't idle. Will crank/run fine and then IPW drops to 0.7. Any idea what is causing this to occur?

EDIT:...

I don't have an "as found", bought the ECM/TCM used. I'll copy over timing tables from a stock 2010 5.3 Silverado tune. Thanks for looking at the tune!

Ah...I have NOT been resetting LTFT's after adjusting VVE.

Made several iterations, seem to be making some progress. For lean cells, I was applying full percentage. For rich cells, if they weren't over 5% or so, I typically did not apply them and when I...

Last tune and log of idle. Table is smooth(er), still rich and making corrections of 13%.
