Reading this thread makes me wonder if the upcoming 2014 m3/m4 that is supposed to have a turbo 6 instead of v8 will basically be our good ole n54 with a Procede like tune.

It's just how the intake and exhaust and all those other little things are setup. Like the X5 3.0si has the same engine as me (N52) but that has 5 more hp (260 vs 255).

The N54 in the 335i came in two flavors. The early N54 had more power then the later ones but the adds all say 300BHP/300FtLbs. The N54 PPK has its own power rating above the base N54 & the 335is has another + the 1M & Z4is with yet another. They also play a game of taking the ratings from different points on the RPM scale which can further blur the numbers. Its generally true BHP (the advertised horsepower) is available up to about 431BHP in the N54 with just an adjustment of the ECU software (no hardware or E85 required) as shown by JB4 et al. The fact remains based on actual dyno tests all the advertised horsepower numbers are low & simply arbitrary numbers based on BMW’s marketing needs.

The JB4 does not put any software in the ECU its all self-contained in the piggy. If its left on the car & switched to Map 0 the OBI port is clear for BMW's service use. They can even update the factory firmware.
It can only be found if the tech searches for it, pulls the cabin air filter, the cowl & opens the ECU coffin

The next time they find mine will be the first. If it was going in for major service it would be a good plan to remove it.
At a $100+ per shop hour they are not going on an Easter egg hunt just to go on a Easter egg hunt. Thing is if they did find a piggy back in 99% of the time they would lose a service customer for their efforts & make the local Indy very happy.

Why, based on typical dynos runs & factoring in 15% for drivetrain loss it has about 366BHP

But remember they also scale up by 15%

My owners manual states that my 335is is rated 335hp. However the sticker on the window stated 320hp. Like some have stated, it's more of a BMW marketing thing.

You can get a lot of different HP numbers off the same dyno run, just read different places on the RPM scale.

I've had to do that twice. Most recently last night. My car went into limp mode, bad crank sensor, no boost. Reflashed back to stock with my AP. Drove until it failed again. At the dealer now. Driving a new F30 328i. Interesting drive. Soft compared to my 335i with sport package an 19" wheels. Steering is okay. Stop start is growing on me. Hate the front end. This car only looks good with the M-Sport front end. |

In my manual its on Page 246 under the reference section towards the back. My car was purchased in August of 2010 built in July. It could be that they later revised the manual (in fact I just went to BMW's website and downloaded the manual for my car and it does not have the engine data section in it).
