BMW 1er M Coupe CRTEK2: N54 Tuning

Dieser Post ist auch verfügbar auf: German

In our todays dynotest we have a BMW 1 Series M Coupe CRTEK2. The new age BMW engines N54 and N55 have a tremendous potential which we would like to show you with our N54 tuning, in this case on a BMW 1er M Coupe.

vehicle

• BMW 1er M Coupe N54

modifications

• cPe Downpipes
• Akrapovic Evolution Exhaust
• aFe Airbox
• Cobb intercooler
• Cobb Chargepipe
• Accessport Custom tune by Chip-Racing

That all new age, turbocharged BMW’s have more power than stated from BMW is no secret, this M Coupe isn’t an exception! The factory output of 340hp was easily exceeded by more than 20hp!

We installed the bolt on parts to get the N54 to Full Bolt On Level, often referred as FBO. After that we strapped in our dyno again and did some runs to see where we are with only the bolt on’s. The results speak for themselves:

blue line:  E82 Original                                                   361hp / 546Nm

green line: E82 FBO Bolt ons                                          396hp / 599Nm    

Most cars suffer from inharmonic torque and power bands, caused by the loss of backpressure in the exhaust, when installing parts like we did on the M coupe. But not on BMW’s, the intelligent ECU is able to recalibrate itself, resulting in a super smooth power band!

As official Cobb Pro Tuner we went one step further and flashed the ECU with a Chip-Racing Custom tune to suit the modifications perfectly. Thanks to the Accessport V3 this is done within a few minutes. After we tuned the ECU we did some more pulls and adjusted the tune until we had this result:

green line: E82 FBO Bolt ons                                          396hp / 599Nm

cyan line: E82 CRTEK 2                                                    440.8PS / 680.2Nm

Verdict

With just a few little bolt-on parts the N54 shows what’s up! With our N54 Tuning we easily set over 80hp free and transform the BMW into a little monster! We will have similar tests going on soon with the newer N55 engine!
