Holy Smokes this has been a brain drainer!! :bangin:
I worked on this for about 7hrs and while general practices make sense nothing worked properly. :wallbash:
2007 Silverado 6.0 LY6 K&N type intake system and aftermarket exhaust (no headers).
I used Swingtan's auto VVE guide, http://forum.efilive.com/showthread.php?t=8961 Followed it to the letter.
First idle was horribly like it was cammed. When starting it would fire then shut down with out correcting using the pedal.
When logging ben's and applying using the "copy with labels" then apply using "paste and mulitply with labels" the values would max out to 10000.
Other times using just paste with labels or any other function including what I just stated all values would decrease the table and not be a "vertical" change but a "hole" in the table. I would smooth this out using a 4% change mostly negative numbers and apply coeffs and generate vve. This helped out cruise area AFR's but idle sucked and WOT was way to lean like 18 aft
My spark table wouldn't always use the commanded amount either. what is holding this back?
Eventually I re-enabled the all the fuel trims except B1510 and re-enable the DFCO. This help idle situations out back to stock but the VE table B8101 was not even close to right.
The other issue was B8101. I would adjust, I would have a error saying zone 12 is too small for a 3x3 area ?? When regenerating B8101 I would save then flash the ecm. I would then open a different "mod" tune and the B8101 table would not resemble anything it should be. I dont have any screen shots of this but will try to get some. The table would generally be flat and have huge spike with a long high ridge through it.
With out doing some idle compensation work, according to the pdf tutorial I dont see how its possible to leave the ecm setup in a complete SD situation. The only way I could get the VE table to closely resemble what the tutorial explained was to manipulate it with out the right data but then after you generate the VE it wouldnt be close anyways. I also had to use "paste and subtract with labels" to have the VE table move the way the tutorial showed.
With all of this not going properly either the tutorial is not correct for my situation or I missed something really big, which I think is the problem.
:help2:
I have 14 different mods to this stock tune and log files to go with each for anyone to help me out with.
I have about 13 million questions about this. Sit back, take a look and go wtf? and then start asking away.
