Chip tuning for DAF LF45 3.9L 150hp (110kW) 550Nm ECU
DAF LF45 (I) 3.9L 150hp (110kW) 550Nm — commercial diesel engine of the commercial segment of the PACCAR (с 1996) group (Нидерланды, 1928). Stage 1 chip tuning raises power from 150 to 172 hp (+22 hp, +15%) and torque from 550 to 628 Nm (+78 Nm).
DAF has been part of the American PACCAR group since 1996. DAF is a Dutch truck manufacturer, founded in 1928. The XF, CF and LF are DAF's main series. The factory calibration is conservative, leaving headroom for Stage 1 while preserving engine life. Mid-range diesels are a mainstream chip tuning subject in the commercial segment. Mid-generation truck models use standard OBD read/write.
The truck chip tuning community is an industry of its own, focused on long-haul routes. Stage 1 on truck diesels focuses on torque for loaded running. The professional logistics segment tunes for fuel consumption and pulling characteristics. Mid-range MAN trucks are a mainstream chip tuning subject in logistics.
