I am of the belief that the 2003 Corvettes have a updated program that protects the cats in a four step manner ..based partially off increased air flow sensed by the maf..
I have been told my increased air flow due to my aftermarket intake..is by tech II scanning tool at 7%..
I am of the belief that the new programing begins to effect the fuel enrichment program after 8%..increase..
Am I good to go?
Also should I avoid a pcm update at my next visit to a dealership on my 2001 Z because the new 2003 program entails this four set protocol..instead of the one step used in 2000 Corvettes.
Would a pcm update on a 2001 Z generally done by a dealer encompass a programing change like this that is in effect for the 2003's and late 2002's?
Or would the fact I have a 2001 Z make the changes to the 2003 Vette safety protocol be a non factor even during reprograming during normal dealer visits?..
All I can say is man! I am glad I never pulled that maf screen! Blockage can sometimes be a good thing..
Besides my ride...just curious..if an a tech II scan device says..I've got a 7 % increase in air flow.. My question is: could effectively a 2001 zo6 or regular C5 4 inch maf effectively be used to control the increase in air flow below the threashold where new cat protection protocols kick in?
Is the screen worth..a 1% reduction in air flow?
That would be a kicker wouldn' t it..Go just up to 8%...get 20ponies..
Go to or over 8% and gain almost no horsepower all b/c of programing to save the almighty emissions devices we all loath..
Thanks in advance for your response.
