Fully rebuilt M50B25 Non-Vanos BMW engine

Engine management: Bosch 403DME + ciptuning,


Other sensors

The engine was measured with 302HP - 6400rpm / 395Nm - 5000rpm, boost : 0.7 bar, conservative tuning.

Current project: bigger intercooler or water/ alcool injection, increase boost to 1-1.2 bar, VEMS 3.3 installation.

The purpose of the VEMS installation is to achieve full sequential injection and direct fire ignition. I'm planning to use the VEMS case with all BMW bosch OEM sensors
