Initial Dyno of Cobb Accessport Tune for the BMW N54
Here we have an initial dyno of the Cobb Accessport on the N54. The car used is a 135i 6-speed. The dyno is on 93 octane pushing around 15 psi of boost. No boost graph or AFR is included which we would like but we will take what they give us. The result for 93 octane pump gas only certainly is not bad but some, including BMS, are expressing concerns about the boost being pushed. This tune compares favorably with the Giac Stage 1. More details below:
Yes you are correct 93 oct
The 135i used was a manual 6speed, and the numbers are DynoJet
No sir, the car is bone stock with 40k miles on it. Never been modified.
Thanks for the questions guys.
I just talked to Doug about it. He said it ramps to 15psi then tapers on the top end to 12.5ish.
