Mercedes-Benz M111 tuning pulley

Tuning pulley

Tuning pulley is the way to change kompressor rotation speed. Higher rotation speed means more air (“boost”) but unfortunately also more boost air temprerature.

Coils

Never changed before? Maybe not. Good ignition and combustion needs a fault free parts. Use OEM coils, they works fine.

Spark plugs

Always start with fresh sparks. Just use OEM ones, do not waste money for expensive “high-performance ones”.

MAF

One of the most important thing is MAF. ECU load model is MAF based. Worned MAF reads uncorrect readings. To replace it, only use Bosch original (or Daimler supplied).

What else?

Tuning pulley kit is just a part of the puzzle, you will need also modified ECU software. Do not forget to renew old ignition parts like spark plugs and ignition coils. Also, change a new MAF to be sure it works like it should be. Why new MAF? Simple, because Motronic ECU load calculations based on MAF reading. Worned MAF caused “offset” of measurement and it means ECU load modeling is not correct anymore. It will cause a wrong load calculation. Always use OEM part for replacement.

Sorry, we are not providing software for your tuning setup, just only the tuning pulley. Please, ask your local tuner to get software done.
