"One of the simplest to use and best thought-out pieces of software available to McLaren owners"
McMedics
As a vendor of and working with M-Engineering, I sometimes forget just how refreshing it is to be partnered with such an amazingly talented and wonderful team of software gurus. M-engineering's "M-Logger" software is by far hands-down one of the simplest to use, and best thought-out pieces of software available to McLaren owners and enthusiasts to data-log or re-flash your ECM.
Last year: Exhaust + tune.This year: 4.0L build. Big turbos. Massive power!
