06 VS 07 ss/sc cars
i was playin with a friend of mines 06 car yesterday. 2.85, 42's, gmpp manifold, k&n intake.
runnin 22 degree's of timing, very conservative to say the least. still under 100% duty cycle with room to spare.
now take my car. stage 2 pulley, 42's k&n header, catback, blah blah.
completely different ve tables, the pe table on the 06 was just ******* nuts!
i can't get over 22 degrees of timing without knock. from day one has run over 100% cuty cycle.
seriously, did gm just say **** it on the 07's?!?!

Hmm, I don't know but my 05 will only take 15 degrees of timing, even with my 2.8" pulley. With meth I can run 23.5 degrees on the 2.6", I'm at 2200 feet above sea level and it usually doesn't get very hot here, around 65-75*f average.

looked at my log last night, 24.0 degrees on stage 2 pulley.
what gets me is, his idc is below 100, mine on a bigger pulley SAME commanded a/f is still above 100. this confuses me!
guess i can look at the base maps

You said it all righ there. LOW 11.XX AFR (big key!) and 94 octane (you lucky SOAB!)
05-06 is CAN-Di

Yeah, the 94 octane has A LOT to do with that. In AZ I had to run 15.5 degrees of timing on 91 octane in order to get no knock (thats on a 140 mph run, I could run 18 degrees on a short burst). Gas has a lot to do with it.

Interesting thread
Not really.
ALL Cobalts are CAN bus cars (techncially called GMLAN) but the LSJ PCM also communicates and is programmed via Class 2 (J1850 VPW) and IDC is NOT even a transmitted PID on the network, it is merely an HPT calculated value based on injector base pulse width and engine speed (RPM)
CAN-Di is merely the interface device added to the TECH2 cable to allow it to communicate with the GM-LAN modules.It is not a communications protocol.

i do know for a fact that 06 vs 07 gm stage 2 maps are different. the inj tables and ve tables are different. the inj and ve tables are better in the 06 cars.
