Since you haven't got the shift kit in yet - are you still running with torque management in the PCM tune? Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 Since you haven't got the shift kit in yet - are you still running with torque management in the PCM tune? Zero tm in normal mode and stock tm in performance/abuse mode... Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 Well put me down for a [email protected] with a 2.152 60'. Too bad I dialed in at 14.79...won first round, lost second round, headed home. I'm climbing that top ET list a tenth at a time if I must!

JF-03-SS Posted June 7, 2007 Report Share Posted June 7, 2007 (edited) Your truck is just slow I say something is still wrong w/ your tune. Maybe Zippy missed something? Did you say that you are at about sealevel? Edited June 7, 2007 by JF-03-SS (see edit history) Quote Link to comment Share on other sites More sharing options...
zippy Posted June 7, 2007 Report Share Posted June 7, 2007 Send me a log of that when you get some time. Something just isn't right there. At least you did make some progress. What have your track temps been? Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 The previous best of 14.74 was in 68 degree weather. The new best was 69 degrees. This is all according to my temp guage in my mirror. I only took one log because I didnt want to mess with the laptop while bracket racing... The log I took was the 14.74 run at 91.7mph and a 2.16 60' run. It showed the mysterious 5-6* KR showing up in Second and Third. There is zero KR in first which is very strange...What would cause false knock? I'm wondering maybe if I have a bad injector? Would clogged cats cause KR? I have no header leaks. Replaced plugs, wires... Here is what I am also thining...besides having the tune adjusted, I'm thinking of taking the 42lbs injectors off of my radix kit and swapping those onto the motor to see if the KR goes away. How long would that swap take? Two hours? Should be plug and play...that way that would be one more thing I can rule out...I want to swap out my coil packs as well...but I dont have the coin to do that and the trans and everything else I have going on right now. Factory coils are $300/set and MSD's are $600...which to my understanding there is zero difference. I'll send that log over tonight Zippy.

zippy Posted June 7, 2007 Report Share Posted June 7, 2007 Your maf isn't descreened is it? Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 I never descreened it...I learned a hard lesson about descreening a maf on my gp years ago...I'll double check and make sure its there...I never paid attention. Quote Link to comment Share on other sites More sharing options...
detjoe Posted June 7, 2007 Report Share Posted June 7, 2007 could you have bad knock sensors?? I would not mess with the injectors untill you firgure out the knock I dont think Zippy misses much, so I would continue to check stuff, but if the knock sensors are bad then you should just start from scratch and get the radix on since you have to take the intake off, could you fry a coil pack form the misfires?? I am glad I did the shift kit and TBTC together, trans work done till I blow this one up or am ready to put the better sererator plate in...

Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 could you have bad knock sensors?? I'm wondering this as well...but, they way the KR acts and is so consistent...I think it might be real... Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 For the record, I dont think its the tune...I've had an experienced powertrain engineer/friend look at it and he said it should be dead on, if not on the conservative side. I think zippy knows what he is doing as well...it might just be that $1.00 part somewhere that is wreaking havoc...you know how it goes...

NoLegs Posted June 7, 2007 Report Share Posted June 7, 2007 What are symptoms of a truck needing a CASE Relearn? Is poor performance one of them? Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 7, 2007 Author Report Share Posted June 7, 2007 (edited) Wow...hmmm...we are still tuning with the original file. I dont think I needed a CASE relearn as the file was not built from scratch or a completely new pcm. I kept the pcm in the truck and zippy sent me a modified file that I pulled from the original pcm and emailed him. He modified that one and sent it back. I used HP Tuners... But that is interesting and something I never considered... Edited June 7, 2007 by Black2003SS (see edit history) Quote Link to comment Share on other sites More sharing options...
SSThunder Posted June 7, 2007 Report Share Posted June 7, 2007 Is the ss missing any? My times went from 14.47 to over 14.8 just on that. The 14.47 run was missing too but not as bad. I didn't get any runs after I fixed that problem but it ran noticably(sp?) stronger. Quote Link to comment Share on other sites More sharing options...
