Stage 4 Transmission Software is specifically for use with Stage 4 Engine Software the High Flow Air Mass Meter Cold Air Intake and High Flow Throttle Body. NOTE: This version of the transmission software is for use with Dinan High Flow Air Mass Meter and High Flow Throttle Body as well as Stage 4 Engine Software. Sporty acceleration is no longer the sole domain of those who like to shift gears; Dinan Automatic Transmission Software welcomes you to the performance zone. To fully utilize the extra power extracted by Dinan Engine Performance Products the transmission software raises the shift points to a higher rpm for faster acceleration in both the ''Sport'' and ''Economy'' modes, allowing you to carry more road speed in each gear. The software also provides firmer and quicker shifting, further improving acceleration. The transmission software will typically shave .01 seconds off of 0-60 mph times and .03 seconds to 100 mph. The software provides the same benefits in both the automatic and manual shifting modes. The Dinan transmission software also provides the driving enthusiast with a revised ''manual'' mode that is better suited to performance driving. In the ''manual mode'', the Dinan programming will maintain the selected gear regardless of engine speed, giving the driver true control over gear selection. Regardless of the selected gear when the vehicle is brought to a stop, the transmission will automatically downshift to 3rd gear. Of course, the driver can manually downshift as the car is brought to a stop, for a more typical 1st gear start. The program will only automatically force an up or downshift in the manual mode when the ''kick-down switch'' is activated by the accelerator pedal beyond the wide-open throttle position. The result is much greater control over gear selection for varying driving conditions and speeds, enabling the driver to maintain the appropriate engine speeds for maximum acceleration.
