Since the last few dyno runs that gave us around 530whp, we decided to completely rewrite the wastegate and turbo control mapping for the N63tu. The new remapping was done on 91 octane/stock downpipe setup and the results are very promising. For the upcoming dyno we might mix in some E85, turn on meth injection and bump up boost though at even at this power level the car is a flying machine.

Nicely done. Was 530 whp on 93 or 91?

The original 530whp dyno taht we posted a while back was done on 91 + 3 gallons of E85 and catless downpipes. Since then we went back to factory downpipes and completely changed the wastegate and turbo behavior.

Any chance there will be a tune for the previous n63 non TU?

Most likely no. We were planning on developing N63 non tu flash, but since the BMW came out with new computer for TU2, we are moving our development onto that platform.

Is that because you can not flash non TU? Meaning you dont have the technology nor the ability to crack the MSD84 ECU. The market is definitely there. I love it.

Non TU N63 can not be flashed at this moment. That is something that we could develop, but our priory now are the new DME8.6 and 8.8 ECUs since N63 is obsolete at this point. Sorry guys.

[BoogieMan2]

Thats some massive gains! Any idea when this flash will come out

[exylyr]

I've been following threads like this for a while now, and a thought occurred to me - if no one wants to crack the N63 ECU since is has gone obsolete, is it possible to replace it with the ECU from an N63tu?

Connectors may have changed, but I doubt new sensors have been added (no increase in pin count). It would be costly to develop a new harness for any vehicle during the middle of a cycle.

So, here's the idea - Mission Performance (or another) could offer for sale a swappable ECU, to replace the obsolete one with one that can be modified...

Give me some feedback!

I am very highly considering this upgrade, but what are the actual gains for a vehicle with catless downpipes?

Is it the 530whp or the 498whp as shown on the dyno graphs listed on your website? Also would it be any greater gain to upgrade the sensors for the $300?

Is it also possible to datalog the vehicle with you to get a perfect revised tune?

Great idea! I think that actually might be possible. I had a similar convo with MP about swapping the the 340i ecu on to my N55 535. Alex said it's possible. The cost didn't make sense though. You might be able to get your hands on a used N63tu ecu and that would make sense.

The TU cars have twin DMEs, vice one for the N63s from what I've read. Not sure a swap is even physically possible. Plus, there were a ton of changes with the release of the TU. I think the odds of us ever seeing a flash tune option are nonexistent. JB4, it would seem is about as good as it is going to get.

Here's what I found for differences between the two, it wasn't just minor tweaks:

Engine mechanical
• New cylinder head due to use of the Turbo Valvetronic Direct Injection (TVDI) procedure
• 3rd generation Valvetronic
• New valvetrain with modified timing
• Adoption of VANOS from the N55 engine
• New cylinder head cover with adapted crankcase ventilation
• Pistons with modified piston crown geometry
• New connecting rod with even pitch and adaptation of the crankcase due to modified connecting rod shape
• Adapted crankshaft
• Chain drive with modified guide rails and an extruded chain with 142 elements.

Oil supply
• Pendulum slide cell pump with small overall width
• Eight individual oil spray nozzles for piston crown cooling.

Cooling
• Integration of the two engine control units in the low-temperature circuit and cooling over the back panel with cooling pipe
• Expansion tank under the left side wall with separate filling hopper.

Intake and exhaust emission systems
• Adaptation of the manifold for the air intake duct due to new geometry of the cylinder head cover
• Use of the hot film air mass meter 7
• Adoption of the charge air temperature and intake-manifold pressure sensor from the N20 engine
• Exhaust turbocharger with new compressor and modified wastegate valves
• Discontinuation of the blow-off valves.

Vacuum system
• Two-stage vacuum pump with new arrangement of the bolt connection
• Vacuum reservoir for the wastegate valves in the V-area of the engine.

Fuel preparation
• Use of the known high-pressure injection with injectors and high pressure pump HDP5
• Discontinuation of fuel low-pressure sensor

Engine management system
• New dual control unit concept with one control unit per bank
• Oil level sensor with an additional temperature sensor in the main oil duct behind the starter motor.

Exactly what gclions said. A lot has changed and we went from 1 ecu to 2. It is actually possible to convert from non tu to tu hardware, though the price would be over $20k. In that case you better off buying LCI 550.

Haha never mind. 20k spending allowance I would put that down on a M4 or 5

If anything, a better option would be to work on making the X5 DME work in the F10. The X5 N63 DME is flashable. From what I understand that is because the X5 doesn't use the flexyray bus. I am wondering if the modules on the flexray bus could all be moved over from the X5 to the F10 and how different they are. I forget how many modules that is off the top of my head and don't have the ECU graph from Rheingold on me at the moment.

FlexRay has nothing to do with ability to flash the ECU, its all about the built-in protection of the ECU bootloader. And swapping in X5 Dme into F10 is not possible.

I wonder why everyone throws that out there as the "reason" the DME cannot be flashed. Just a protocol change did not make sense to me so I'm not surprised. Thanks for sharing. Any ideas why BMW went less strict on the bootloader protection for the X5 DME?

Why did you go back to the factory downpipes?

What were the new dyno numbers with rewritten wastegate and turbo control mapping?
