PPK Stage 2 N54 Install/Review w/ Dynos
I had the factory Power Performance Kit (PPK) Stage 2 installed in my 2009 E93. The Stage 2 includes an auxilliary coolant radiator (installed in the driver's side front fender well), a larger radiator fan, and an ECU flash for a modest increase in torque/horsepower.
I know it's not a very popular tuning option, but I'll share my reasons. I wanted the increased OEM cooling capacity as a solid base for any future tuning; I wanted to preserve the original and CPO warranties I have; my power goals are modest for now, until I add an LSD and some beefed up suspension bits. I am more than satisfied with the results. Throttle response feels much smoother and broader, with no hint of lag, suggesting the torque curve had been raised and broadened, greatly enhancing tractability between 3-5k rpm, which is where most of my driving happens. I would agree with comments made by others who had the PPK tune along the lines of "car should have come this way originally". Feels really good, in an organic sort of a way. But impressions are obviously subjective, and I wanted to know quantitatively what the tune actually produced, so I had a baseline dyno session done before the install, and then went back to the same outfit for an "after" dyno run. Charts are posted below. Results: the PPK tune delivered a better-than-advertised increase in torque, approx. 45 ft/lbs (!) across the band. Increase in HP was as advertised, approx. 20 HP across the band, although comparing peak to peak, HP was up only 16. The baseline runs showed a pronounced HP peak at about 5600, while the PPK runs show a higher, flatter HP curve there, but if you look across the band, the "before" and "after" HP curves track between 3k and 5k at a consistent 20 HP difference. I thought the numbers confirmed my driving impression - a nice increase in power right where I could feel it the most. First chart below shows the two baseline runs. Second chart is the two-run session a few days after the PPK install. Third chart is the overlay of the "before" and "after". Note about the dynos: after checking online recommendations in my area (I live in Austin, TX), I went to Henderson Performance in nearby New Braunfels. Corey Henderson is the owner/operator, great guy and really good to work with. He's a Chevy guy (lots of LS1 car porn in his shop), but graciously tolerated my little German machine. He personally operated my car on the dyno, and the consistency of the runs is a testament to his thorough, smooth approach. Felt like my car was in good hands. And at $60 for two pulls, cost was very reasonable. |

Yes I did this also when it first came out. I sought of thought like you in the beginning but after a while I wanted more. So I bought the cobb. Looking back a waste of money for me. Hopefully it will be enough for you. Congrats

Try a jb4 (or cobb/procede/giac/etc) if your impressed with a ppk stage 2. Cooling stuff is awesome though!
some decent torque on some runs! |

Good review, and I agree the cooling parts are worth it.
btw did you log boost? I was always curious what boost it targets with ppk? I would look to see their timing curve as well but I'm pretty sure that you don;t have that

I have the PPK stage 2 and a working INPA but I haven't explored INPA much yet. Tell me the steps in INPA to read the assembly number, and I'll share the results.
OP, thanks for posting this. Good to see a baseline dyno along with PPK improvements. I am pretty happy with the feel of the PPK though I have nothing to compare it with as I bought the car with it already installed. A friend just scored me a great deal on a Cobb AP so should soon be able to compare PPK vs. Cobb. Waiting to get the car serviced before I install it. |

don;t worry you won't lose your PPK because It will be backed up and will be reflashed when you uninstall.

well if you have the BT tool, you can use it for logging.

the JB+ will make more power and is cheaper (much cheaper). but with all due respect it's crap. not the right way to tune.

Hmmm... No BT tool here. Just BMW Standard Tools and K+DCAN cable. What logging software is available? Could I use BMWLogger or is there something free? And has no one figured out reading boost on the OBDII?

@wedge1967 would be the person to ask since I don;t have any experience with what tools you have. I would assume you can...

Open INPA and select the model, select engine, select DME 80/81, then select info. I think it's F1, but off the top of my head I can't remember. I'm actually traveling right now and have no way to test it.
