M2 drives nicely w/the TurboSmart in place

Seems snappy, w/slightly more urgency

I'm going on a overnight drive with my local chapter of BMWCCA this weekend w/14 other BMW's

I'll have more of an opportunity to drive the car on this overnight trip… We're driving a nice healthy 6 1/2 hours from our meeting point Northwest BMW to our destination

Then a nice return drive home on Sunday

Here is a google link to our trip…

The car is definitely running extra smooth with this DV

I'd like to say it feels a little quicker as well

Appreciate the update.

What brand sport cat are you going with?

Any plans for a tune?

Personally I've got a couple months warranty remaining, then I'll be doing:

1) intercooler/charge pipe & sport cat

Drive like that for a few weeks then

2) DV & turbo inlet

Drive like that for a few weeks then

3) Stage 2 tune (undecided mhd or bm3)

I am going with Fabspeed most likely

I prefer their euro cat design

I'm going with EcuTek

Not sure when

[Sundinisagod]

Love the sound of the Fabspeed! Best of both worlds sonically, adds some rasp while adding some nice muscular deep tones as well. I’ll probably end up getting the Wagner though, due to its more affordable price.

+1 for Ecutek. Wish I had gone that route from the jump and just included a HPFP from the get go when moving to “stage 2”

Perfectly happy with BM3 but I want a custom tune from Bend Cal and they only support Ecutek and won’t touch an OG M2 unless it has an upgraded HPFP.

I installed this recently - the actuator lead coming out of the Dv was pressing against the coolant piping, but only very lightly, so I decided it was OK.

Yeah my advanced OCD went haywire

I ended up unbolting the water pump and dropping it enough to convince myself it was going to be okay

I personally like the DV's addition

What are your thoughts?

Yeah, I've been meaning to post about that....

I did both Dv and inlet at the same time.

The inlet is brilliant - the extra 8—10‰ of breathing it affords is really noticeable, with the engine pulling alot stronger.

The Dv I've been less impressed with, and either a leak or misplaced assumption are the cause. The turbosmart Dv is a quality bit of kit for sure - it's very well made.
My issue though is that I thought it would behave like the gfb dv+, where I saw in logs that a minium boost was retained (iirc 2.5 — 3psi), even several seconds after accelerator lift off. For me, this was the reason to expect better on/off throttle response. However, my dv isn't doing that - the psi falls to nothing within a few seconds.

Here is a log: https://www.bootmod3.net/log?id=6277...0b4301a1d9ac82


What are people's logged findings with this dv? Do you retain a minimum boost, or does it all go?

Thanks.

Interesting I have had no issues with mine

But I don't have boot mod so I can't help

Maybe someone else can comment on that data-log that you posted

My inlet came loose because the lower hose clamp was busted and so maybe your DV or the inlet itself is loose

[widetyres]

AmuroRay please can you share a recent log with your turbosmart dv installed? Thanks.

[widetyres]

I dug back through through the forum and found a log by ZM2 ((he also has a turbosmart fitted):
https://www.bootmod3.net/log?id=5ee4...729b0ea9b3c476
(sourced from this post: https://f87.bimmerpost.com/forums/sh...6&postcount=30)

This logs shows the same behaviour as I am seeing, so my car is running fine.

As mentioned, it would be nice if the Turbosmart retained a little more minimum boost in the pipes when off throttle. It looks like the GFB DV+, with the strong spring option fitted, is the way to go for that though.

I agree with this for sure - the Fabspeed with the stock exhaust is a great sounding setup.

I've got an Akropovic cat (which has the HJS euro 300 cell in it) with stock exhaust. It sounds really good, but runs at a slightly lower pitch and is missing the extra racy rasp that the Fabspeed offers.
I'm very happy with mine though as picked it up barely used 2nd hand for a good price, but if buying new, Fabspeed is a very good sonic choice.

That's for the top bolt of the diverter valve

The other two I was able to get out with the combination of extensions and a 5 mm hex key

I adapted the Farkle method, and ended up holding the ball bit as shown in the picture.

It took a while before I discovered the claw of the flexi arm to help me - if I had been using it this way at the beginning, it would have saved me over an hour for sure!

What transmission do you have ?

You might want to check if the valve is leaking, alot of users on facebook have allegedly reported the turbo smart valves were leaking due to faulty o-rings.

I have 6MT in my car

What are you looking for exactly? A single gear pull or multiple?

Mine does that -
https://datazap.me/u/amuroray/3rd-4t...-30&zoom=49-99

This is old, but I do hold about 2.9lbs of boost or higher during the gear change. I don't see a reason to get the GFB+ but to each their own.

Better fitment, reuse of the extremely reliable factory components, and no compressor surge which has been reported to happen alot on the m2.

Mine was plug and play and has been dead reliable and performed excellent. I would tell anyone to reset adaptations after installing new parts then drive HARD, and see how they old up.

It is PNP but on the m2 it seems to hit the coolant hose, I've heard this from a few people now.

On the Facebook groups I hear alot of people with alleged turbo smart boost leak issues, compared to the gfb.


I wouldn't drive hard after resetting adaptations, because the ecu is going to be pushing to its limits to find areas where it has to pull back to adapt and that's not going to be ideal if you have bad gas and a mod that isn't playing well. That sounds like asking for preignition. I always drive it gently and progressively lean on it, that does make adaptation take longer but it is less risky as you're progressively pushing the car.
