for a friend

can someone give him a long list of what will pull timing! he has his timing set at 16 degrees on high and low octane tables while in boost and its going as low as 11-14..... Its not high iats or water temps!

 

knock
burst knock
torque management
every timing table

those are the usual culprits.

 

COT has a Spark Retard parameter

 

Thanks guys, im the one with the problems lol, i forgot to mention i just switched out the 4L80E and stuck a Th400 in its place, will this have any effect? And COT? i dunno what that is lol.... Its a 2002 HD Chevrolet Truck Computer..... Thanks for any help

 

You can log all of the Spark Retard PIDs and know exactly
who's bugging. Otherwise you have only a list of suspects.
Of course there's also the possibility that it's some Advance
element that goes negative. Log 'em all.

 

ok thanks, the truck recently got a cage and solid motor mounts too so im sure this might have something to do with the knock sensors... Ill let ya know thanks again!

 

8.0* of burst knock, zeroed out burst knock enable delta cyl air threshold vs rpm and burst knock retard vs rpm.... then got a little of KR like 1.5 in one cell.... this is just sitting in neutral and a few small revs
