Yes that and the larger turbos, revised manifold, etc. It's like a 150whp+ difference tuned.

As someone looking at a '12... can you please elaborate??? I'm new to the platform.

The s63tu starting in 2015 (I think) is way better, but costs a lot more. If you care about racing get one of those. :)

Tweaked the PID tuning a bit and saw some more improvement. Now I just need to get the shift boost logic adjusted and I think we'll be pretty well maxed out for E30. Then back to (boring) 91 octane tuning.

This shows you the difference: http://www.bimmerboost.com/content.p...M5-and-E70-X5M

E70 X5M:

F85 X5M:

The F85 is flowing much more up top. In stock form it is providing more power than a tuned E70 X5M.

Now, with the new manifold and turbos I don't see any reason the E70 X5M can't match the F85 X5M.

What you're seeing with a tune here from BMS is major torque gains down low. It's the top end of the curve where the old X5M struggles.

Terry, where do you see IDC at this point? Is there much room left to keep a set of upgraded stock housing turbos breathing up top? I've always been a pump gas guy, so I'm not too interested in e85 or supplemental fueling numbers.

Very close. Just about there. http://www.n54tech.com/forums/images/smilies/smile.gif

The fuel system seems to have plenty of room, although with larger turbos a back end flash map will be required.

Pretty good. I'd love to see a JB4 backend flash setup with Pure Stage 2's.

How do these numbers compare to the newer X5M S63TU tunes from BMS?

The s63tu cars are in the low 11s, I think. But I'll have to find a good apples to apples comparison to see how much faster another 100whp+ gets you.

Great job Terry!

Glad to see this, but honestly would think there is so much more room on the latest N63tu in the 50i.

The tune I had on my older X5M put down similar numbers Vbox, albeit quicker to 100. Best trap tuned I saw was 112 while a stock 15 50i will turn that.

Terry, I'm more than willing to let you play with and log on my 15. Let me know.

You make a point about the potential of the new one.

A JB4 alone will make a big difference it just needs to be developed. Should be easier now that Terry has experience with the various X5M's.

@Terry@BMS

I may take you up on the n63tu one of these days. I'm sure it has more in it, just would need to develop a JB4 for it.

There's a multitude of things that make the S63TU better than the S63, but I'm still trying to see what exactly can be swapped from platform to platform to decrease that gap.

Terry, I'm extremely interested. I believe hutch and I reached out months ago, looking for a solution. I'm sitting on a s63 with stage 1 Pure Turbos & catless DPs. I'm needing a solution to to make this run like it should... I have dynoed every step... I need fine tuning and real time data logging and long term logging. HELP! lol

Sorry for the late reply. Just email us, it will work for you. :)

Terry 12.0 @ 119 is great for a E70 tune only.

What at are you seeing on the F85 X5M ?

I don't think he has tested it yet. @Terry@BMS

Considering the incremental decreases made in quarter mile times as you've tweaked more, is this something that can be accomplished via emailing logs back and forth, requires hands-on tuning done by you or is this something that will come preloaded in the JB4 and will be readily available to everyone who buys one fresh outta the box?

How much of a difference did the Pure Stage 1 make?
What kind of numbers are you putting down?

Hey Terry, Sent you an email!

I personally went with Halim/HCP as he's very active on these boards, he's gotten great numbers from his M5 and a reputation to match and not to say he'd do this for everyone, but he's been very helpful with me for over a year via WhatsApp when I was trying to resolve my reduced power warning issues. Now that those are solved, I'll also be returning to the dyno for further tuning and he's already been helping with my JB4 settings. I'm sure for a nominal fee Halim will help you out or you can write Terry and figure out how to use your Velos tune as a back end flash and use the JB4 logs for further tuning.

Currently I'm running a HCP stage 2 tune, catless downpipes, new injectors with a custom intake. I've got the JB4 ready to go, then I've got a custom catch can setup, M5 headers and Pure stage 2 turbos that'll be installed this spring when I don't have to DD my X5M.

---

Did you ever dyno this setup?

At time I didn't have the custom intake, I flashed back to a stock tune even though I had catless downpipes (and a CEL to go with it) and was still experiencing the reduced power warning which you can see as the power breaks up the top end before kicking the error. At that time I also had a boost leak at the charge pipes and I think I still had a vacuum pump oil leak as well. Fixing the boost and vacuum leaks and resetting adaptations made a nice difference in power, even on a stock tune. It's a beast on stage 2 so I can only imagine how it'll be with my current mods waiting to go on.

Ummm, no tune is going to fix a problem with your hardware. Get that sorted before you even think about stomping on it or getting the car tuned. A fault vacuum line can cost you a motor. I've been there and it wasn't fun.
