setting B3618 PE AFR with cam and supporting mods

[joecar]

Note that AutoVE is a special case of the Calc.MAFT procedure...

I say this because if when you're finished tuning you intend to run the MAF, you will need both MAF and VE to have been corrected.

I'm catching up on threads, I'll have more comments later...

Post your calc_pids.txt file.

I'm not sure I follow but perhaps you are asking for this? calc_pids.txt

[myws6formula]

Do Calc.VET initially to get VE and MAF tables close... and then do AutoVE if necessary.

From your pid list remove GM.CYLAIR_DMA and add HO2S11/HO2S21 (the front NBO2 voltages)...

make sure to keep pid channel count no bigger than 24 channels (see bottom of PIDs tab in scantool).

ok , I set it up like this and that puts me right at 24 pids

under advanced notes I do see talk about disabling DFCO and changing the o2 switch points B4105: O2 Switch-points to 450 Millivolts
Smoother MAF & VE Table

Yes, correct, thanks... I'm looking thru your files in post #10, I'll have some comments later tonite.

Yes, during tuning, disable DFCO to avoid the lean jump on decel, and set B4105 to 450mV in all cells (later GM calibrations do this also).

any ideas? I want to get a log done tonight but i want to make sure nothing is out of wack. I checked and I guess I must have changed the o2 and DCFO already

[joecar]

MAF table can't be jagged.

VE table can't have sudden holes (or spikes), but otherwise ripples are ok.

HO/LO spark tables are too close together.

Your wideband fluctuates too much making it useless... try setting it to 1/6th using the LM Programmer software.

IM really lost on this.. if I had any hair left it would be pulled out.

I setup the wb as you stated and im not sure what to do with the spark tables? should I just import the ls6 spark maps and copy my low rpm and idle ranges back over it?

I gave up tuning it before and im hoping this time around I can get it done

Don't get discouraged! We will try to help you - sorry I haven't been on here much to help this week - I have been trying to get this new job and had to get a bunch of things in line for that... plus my wife and I have a 2 year old and 7 month old (keep us very busy)...

What we are saying about the spark tables is just that the low octane is too close to the values of the high octane table (I usually use 4 degrees lower on the low octane). Also, I would pull about 2 degrees out of the high octane in the WOT areas until you get it on a dyno. I'll attach your tune from further back with the spark table recommendations...
