GTS Flash
Hi guys
I have a 67 plate M4 Comp and am thinking of getting the GTS flash when the warranty runs out. Any thoughts on this in terms of the improvement it will have and also would this increase the pops and crackles or any other ways to increase the pops and crackles without any exhuast modifications. For the GTS flash, any suggestions on who to best carry this out? Thanks in advance |

Any decent coder can do it remotely for you. I'd recommend Zed coding. Expect to pay approximately £150 for this. Included in the price will be GTS LSD, TC, steering & CS EDC if you want it. More pops, bangs & burbles is ECU mapping though. No need to change the exhaust. So really, you should consider BM3. You should be able to get it for around £400. Try Tom Wrigley Performance. I'd suggest stage 1 map if your cars not modded. It's included in the price. You don't have to use it if you don't want more power. You also get all the free maps, which include GTS or CS if you fancy just a modest power increase. As a bonus, it also gives you the GTS transmission flash. With BM3, you can tailor any combination for exhaust noise. It really is an excellent package for the cost. You can even just stick with your stock map if you like but still play around with the exhaust burbles settings.

+1 I had mine done by Zed Coding recently. Very noticeable difference. Faster crisper changes upshift and downshifts. But also somehow smoother!? Mines a 2018 M3 competition DCT. Steering didn't notice a massive difference just felt slightly lighter in all modes and a tad more responsive. Biggest change is the DCT flash IMO. I wouldn't worry too much about warranty. The TCU is not locked so this flash should not trigger any tamper detection codes unlike a DME unlock for example. Meaning it's easily flashable back to stock without much trace at all. On top of that it's BMW software for an identical transmission. Mines still under warranty and I'm not concerned at all. If anything the smoother shifts should ensure the rest of the car and box gets and easier life

So something like a BM3 Stage 1 with GTS flash and then customise the exhuast burble settings?
For a BM3 Stage 1, would everything else stock be fine I.e. wouldn't put a strain on any stock parts? Cheers |

Just buy Bootmod3 and then you'll get this and also a stage 1 map as well.

I'd just warn that the GTS included with BM3 hadn't used to be the latest version that you get from the likes of Zed Coding, though it is an improvement over my MY17 standard. Neither does it include the MDM diff changes that I understand are worth having too.

I've not had it on a rolling road before or after so can't give anything other than seat of the pants experience. I'm very happy with the noticeable increase. Must be around 500 flywheel I'd estimate.

But the stock shocks are poor. They're really the root of the poor ride, which I appreciate is a subjective viewpoint. My Bilsteins have their own settings. How these settings compare to BMW's, I have no idea as the damping's in a completely different league.

When my plug service comes around, BM3 do recommend NGK Iridium plugs (they run cooler apparently), gapped to 0.2mm iirc. So will probs get those for when it goes in. But not before, as I think it's just unnecessary expense.

On a GTS flash only, what would the expected enhancement on the burbles on a comp pack in terms of more prominent/louder and frequent?
Would it be adjustable on a GTS flash (without BM3) or would just match the burbles on a GTS? Cheers guys |
