Dinan Stage 4 Transmission Chip - 1996-1999 BMW M3

NOTE: This version of the transmission chip is for use with Dinan High Flow Air Mass Meter and 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. Please consult the Dinan chip guide under tech resources to help us accurately identify what chip is best suited for your vehicle.
