Procede n55 tune update
Currently running our 2011 DCT equipped 135 at 14-15psi on 91oct pump gas. Ah, the beauties of timing control A few things we noticed so far:
-The factory turbo wont be able to hold much more than 12-13psi at 7000rpm in 100% stock trim. Even with 100% wastegate DC. Intake and exhaust upgrades should help. Until then, we are running things a bit more conservative with max boost in the low end/mid range at 14-15 and tapering to 11-12psi by redline. -DCT Transmission is incredible. Even at this moderate tune-only state, the 135 feels about as quick as a fully bolt-on equipped n54 car with 6AT or 6MT. I can see this car put down some alarmingly good 1/4 mile times. -v4 Boost control+DCT is a match made in heaven. With boost target always close to boost actual, the DTC shifts solidly and quickly exactly when you want it to. Great fun. -Even at this boost level, no codes, tuner or otherwise. For those who care about the tech details, yes, we have full v4 control. That means full logging (oil temp, ignition advance, map1, map2, MAF freq, actual throttle blade, etc.), CANclear, code reading/clearing, Vishnu Control Center, etc,. Basically, we are coming out of the gate with a full proper tune. Not a first-to-market quasi-tune. Below a datalog of one of our recent test runs. You can see how quickly the transmission shifts gears. And how no boost is lost when doing so. Pretty amazing. Can't say too much more at this point. But perhaps we'll post some more videos later this week demonstrating how far along we are. I promised we would get up to speed quickly with the n55, didn't I? Cheers shiv |

Shiv, great job!
You guys are always incredible. I see now you are pretty close to finishing up with the N55. So what about us N63 V8 owners? Any hint or news? Thanks in advance and keep up the good work. |

Thanks for the kind words. The N63 is in our sights for sure. Just want to put the finishing touches on the N55 first. I'd say we are about 90% done at this time. Which actually puts us ahead of schedule

I already asked him the same question and he told me that this was the earliest it can be produced. I recall that he mentioned that BMW Welt will start producing them at that time. |

Can't wait to see the final results and power increase numbers. Been hearing (reading) great things about Procede V4.
That new cruise control stalk activated menu is |

I emailed Procede over the weekend, haven't heard anything back. What I'd like to know is why can't this already be happening? My friend had a Procede tune installed on his 2011 X6 35i which has the same powertrain.
