This ECU remap is for installation at Evolve. Being amongst the first to remap the BMW 135i we've perfected the upgrade to give significant gains throughout the rpm range (see dyno graph below). Evolve have upgraded hundreds of twin turbo 135i's and 335i's and we we understand these cars very well. The 1M uses the same N54 engine as the 135i/335i with the addition of a BMW Performance Pack. The software upgrade was designed and tested at our dyno facility and on road to give optimal performance with maximum safety. Much time was taken to develop the software to give improved throttle response and factory like drivability with a progressive power delivery. We can take your 1M even further with the Evolve Intercooler (FMIC) and Evolve Exhaust System. Overview: 30-40 bhp 40-50 lb/ft torque Factory drivability with more power everywhere Smooth and progressive power delivery Dyno and road developed Free updates due to dealer overwrite Already have other modifications?
