The intake plenum take the air from the filter and allow it to be sucked into the engine and mixed with fuel. Pulling more air and fuel into your OM642 is the main goal to any engine performance tuning project.

It will usually give you around 30% more power on turbocharged vehicles and you can expect to see around 15% on NASP engines, but the outcome usually rely on the mods you've fitted and the condition of your engine. (In some cases, as the factory ECU is locked flashing is not an option, so an aftermarket ECU is the route to take, and many of these will outperform factory ECU's but make sure it has knock protection and that you get it setup properly.)

The OM642 engines make great tuning projects and we're pleased to see that there are quite a few choices of parts and performance parts out there.ĮCU mapping will help unlock the full potential of all the mods you've done to your OM642.
Ported and polished head, Fast road cam, high flow fuel injectors, induction kit, Sports catalyst & performance exhaust, fuel pump upgrades.Ĭrank and Piston upgrades to alter compression, Engine balancing & blueprinting, Adding or Upgrading forced induction (turbo/supercharger), Twin charging conversions, Competition cam, Internal engine upgrades (head flowing porting/bigger valves). Sports exhaust manifold, Remaps/piggy back ECU, Panel air filters, drilled & smoothed airbox, Fast road camshaft, Intake headers. The ECU mapping and fuelling also have a large bearing on the bhp gains you'll hit.Įxtending exhaust or intake durations can alter the bhp band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations. Some OM642 engines respond better to more or less aggressive camshaft durations so view each engine as unique.
Mercedes chip tuning driver#
You should ideally optimize your bhp range to your driving style so for a daily driver stick with a shorter duration OM642 cam If you are developing a track car this doesn't matter as you are in the high end of your RPM range anyway and that is where you want the power to be. Motorsport cams, push up the top end band but as a result the car will not idle smoothly and low end power nearly always suffers.Ī Motorsport cam makes it harder when on the daily commute, because the lumpy idle will make the car prone to stall and smooth driving at low rpm becomes impossible. The intake & exhaust durations will alter depending on the chosen camshaft profile, so large bhp gains are on offer for camshaft upgrades.įast road cams usually push up the performance throughout the rpm band, you could drop a little bottom end torque but the top end will be lifted. The camshaft profile plays a big part in the engines power output so camshaft upgrades make quite a large difference.
We won't be swayed by popular OM642 upgrades, they need to be cost effective. The best OM642 upgrades on an engine are obviously the ones that give the biggest return for your cash. Tuning the Mercedes OM642 and best OM642 performance parts.
