OBD unlock and bootmod3

There is also a transmission flash for the DCTers to make the car smoother especially with the extra power, I believe they were just trying to make you aware of that as well.

It is unlikely anyone has a direct copy of the CS yet but it's only around 10hp more than ZCP. If there is a company that can replicate that, it's Pro Tuning Freaks with their BM3 product. None of the other tuning companies offer any real customized tuning for their customers that have the desire for it. The other guys only sell prepackaged tunes.

That's exactly why I asked for the replica of CS tune instead of GTS but someone said they have GTS tune etc. It's not only about an additional 10hp. It also has 37lb-ft more as well. A tuner can easily come up with these numbers but the reason I'm asking for an exact replica of the official BMW tune is that I know the power delivery will be much improved. Anyways, as I said I'm not interested in exceeding GTS power figures. I track my car and a modest improvement in the power department along with much better delivery of that power is what I'm after.

You do know that horsepower and torque are correlated right?

Given that non-GTS cars do not have water injection, how does the bm3 GTS map deliver the power increase?

I'll explain one more time and stop hijacking this thread. I don't care if CS offers just 10hp improvement. I wouldn't care even if it made the exact same figures as my ZCP. One thing I know is that BMW made improvements on how to deliver that HP and torque (you can take look at their official dyno graphs and press reviews etc). So, unlike many of us here, I'm just trying to get my car as close as possible to CS as I think it'll improve it's track performance. I'm neither an expert nor do I want to be. I just asked a simple question and I think I got my answer. I don't think what I want is possible today, not yet at least.

Increases the boost pressure. The GTS can also run without the water injection if the tank is empty.

Read this link for "The BMW M4 GTS can seamlessly adjust for a full or empty reservoir without issues".

Understood that's why I mentioned the GTS DCT coding, as the CS probably has both, but we won't know until March 2018. Attached file/pic is from one of the coder sites. Just trying to help you out.

Right, but from what I’ve read the GTS map ‘seamlessly’ reverts to stock power levels when the water tank is empty.

Also, your article implies that the increased boost is reliant on the water injection:
“The water injection system cools the air significantly enough to where the turbo's boost has been safely increased to 22 psi from the standard 17 psi on the base models.”

So is the bm3 GTS map a mimic of the actual map, or is it actually a modified derivative of the OEM GTS map with the water dependency bypassed?

My German tuner told me that 23 psi is safe for the S55, but that's with BMC airfilters and akra catless dps. Don't know about the bm3 GTS map, but the engine can handle it.

Mine is a 6MT

U guys are wasting a lot space for such a tiny, niche request.

Let's focus on OBD Port flashing and not BM3 tunes/features that already exist since there's other threads for that

I’m sure that level of boost safe if done right, but that isn’t really what I am asking. If the bm3 GTS map is simply the OEM GTS tune with water dependency disabled, that wouldn’t be as safe given that the OEM GTS was designed to use H2O injection to decrease the risk of predetination. To be OEM levels of safe, the bm3 GTS map would either need to leave the water dependency intact, or it would need some bespoke tweaking (fuel,timing,lift etc).

Thanks. I was having a hard time deciphering this from the other tuner threads.

This is all you need to understand. They are 2 very different routes with different outcomes.

OBD unlock is in testing and we'll have more details to share soon. Short answer is anyone looking to go the OBD unlock route instead of bench flash will be able to do so at home or at any of our supporting dealer locations.

There are a few more cool features on the horizon very soon but we felt this one needed to be announced first.

Interested!!

I mean, mine is already unlocked anyway. lol And i wouldn't go back

[Woodengun]

cntzl - there is a FB post by pureturbos.eu that you should see. Posted November 5. They have a BM3 tune and using 93 octane (98 RON) have very good looking power delivery for tracking - power climbs all the way to 7k rpm. Stock power band isn't so great for tracking since the power flattens out around 5.5k and then dips around 6.5k. Kinda makes the higher rev limit useless at the track.

Just need to be able to stomach new Pure turbos, the BM3 tune and fill up with 93+ octane. I wonder if BM3 has a similar tune (albeit less peak power) for stock turbos.

I was going to remove my ECU for bench unlock next week but now I'll hold off

What you stated is the cons of bench flashing since having to remove or mail it is a labor intensive process. The negatives are obvious.

My question was the positives gained from doing this.

It was stated that OBDII port flash can't read all the files. Also you can't revert back to completely stock using OBDII.

Wanted to know if this is true and what other advantages are there to bench flashing.

You cannot return fully back to stock without putting the DME on a bench. This is true with all of the OBD Flashes that have recently been released.
