We now proudly offer custom PCM 
programming for all 97-09 Chevrolet Corvette Models including Supercharging, and 
other modifications.            
     
If your GM car is a '96-and-later, it incorporates an OBD-II-based PCM, which 
controls the transmission as well. For engine control, the PCM takes many sensor 
inputs (O2, TPS, RPM, MAF, MAP, etc.) and calculates the target outputs 
(primarily spark advance and fuel-injector-duty cycle). The PCM contains various 
switches, constants, and tables that control operation of the engine, 
transmission, and other aspects of the powertrain. 
Tuning 
Basics
General fuel system 
adjusting, power enrichment, and timing. It is preferable that you perform 
tuning in the order of these parts. To maximize the power increase, you'll need 
to use premium gas to minimize knock.  Computer/PCM/ECM/BCM, Computer
