1996-1999 E36 318 Z3 Naturally Aspirated Software

Want more power from your M44 motor but not willing to supercharge just yet? Then our M44 performance software is just what you need. The software has modified fuel and spark maps for increased engine power and response, giving your motor a significant boost throughout the powerband. The software also increases the rev-limiter to 6800rpm, allowing you to wind it out just a little more when you want to, as well as removing the pesky vehicle speed limiter. Users of the software have also reported an increase in fuel economy. See below for dyno results.
