with a little help from others (most unknowing)

I've ended up this way:

* Stock 2003 Silverado SS VE and fueling tables (almost a complete set, I've skipped a few)

* marc_w's timing and KR tables from his 2003 Silverado SS (with very slight mods)

* MY CMotorsports tuned 4L80e trans tables with the shifts softened up just slightly

*idle is ~675rpm

*The knock sensors have been desensitized about 30% to control the dreaded '99/'00 false knock, I see the occasional 1º-2º of KR but it's pretty random and usually at part-throttle/full load

* there are placed in the timing tables that have over 30º of timing added as compared to stock....and still almost no KR....pretty amazing


I'm still working on nailing the VE table down using the ST's and LT's, the spark tables are about as perfect as I could ever do (many many thanks marc_w)

This truck has NEVER run better, it's part-throttle and cruise response is unbelievable and it idles better than it did before the heads/cam !!!. I can't believe the urgency it has off idle and when you plant the pedal traction is NOT an option

 

Shweet man. Nothing like having your highly technologically advanced pcm driven truck running good. Congrats to you man!!! Seriously, as long as all safe gaurds are met, lots of people wish they coud say the same!

Which specific tables did you kill 30% on. And where was your low rpm/high load changes on those tables. I've noticed some suffer at lower and/or higher rpm's than others. Just curious.

 

i wish my idle was around 675

good job tho, im glad you have everything worked out, and that'll be good for people who cant seem to get things right either. I know i'll be taking this into some consideration when I retune... my truck is running like garbage right now

 

Thats what I said 6 months ago, I just know got it too drive to the level I wanted.

Here is a challenge turn off the ltft's and get all your stft's within 5% error in SD then turn the maf back on and tune that table. Its where I ended up, I hated the fact that I could take long trips and it would drive better after the trip, now it as consistent as a carborated car.

 

Engine--->Spark Control--->Knock Sensors--->Tip in TPS and vs. RPM vs. Cyl both raised about 30% across the board

Engine--->Spark Control--->Spark Retard--->Knock Retard Decay raised about 30% across the board

 

across the board eh? even in the WOT area...5K +? Works for ya! I just attacked specific areas. On your tip in(I am asking cuz I can't remember stock #'s or I'd just add 30% as you said) range of 2400 rpm to 3600 rpm what value do you have?
