It's been really quiet regarding a tune for the G8x series. I'm hoping that eventually one of the speed shops will unlock the ECU enabling an OBD tune. If so, I would be all over it like I was when I had my M8.

Matter of time man. Same happened with F80x gen, hopefully by next year we should see reputable tuners releasing their tune. Waiting for BM3 myself.

Yeah I had BM3 on my 2016 M4 and it was really good.

Just let someone else shake it out over the next year or two. I dont want to be a guinea pig

Yes, especially with a new and expensive car; and no way will I remove the ECU for a tune.

M Engineering has an OBD flash tune for the 992s now. You would think one of these outfits should soon have one for the M3/M4.

Hopefully. Both are MG1 Type ECUs from Bosch.

Just be careful as I learned the hard way not to perform the remote software upgrade. I performed the remote upgrade in my M8 (no longer own) and it erased my DME tune.

Yea bm3 with this = the bimmerpost de facto combo. Cannot wait to see what this car can do with a bm3 e30 stage 2 epic tune.

Think we're gonna be seeing a car break 10s quarter mile on stock internals.

I had BM3 back in 2017 on my F80 M3 comp running the CS map. Ah those where my funnest tuning days. It was so easy and it just worked great. I never had a single issue. I still have my BM3 wifi dongle thing too. I dont plan to tune this one. But if they make their way to the G8X platform I know I will want too. lol.

No question. Upgraded turbos with a legit ECU tune will get it done.

Man if bm3 available add DP's, mid-pipe, E85 you're in 9's in an xdrive.

I will most likely go with upgraded turbos when an ECU does come out. The car will be a screamer for sure.

We will soon. Would rather wait for something tested and true than something rushed to market.

Kratos has been quiet. Wonder what's brewing.

[M0J0]

They will come out in 2022.

New to the BMW community. What's a OBD tune? Doesn't the JB4 offer this? Or are you referring to open code tuning?

https://burgertuning.com/collections...-g8x-bmw-m3-m4

Or is it safer/better to wait for a Dinan tune?

Flash tune….meaning nothing gets removed or attached to be able to run a tune. Just computer software gets injected to the ecu via OBD.

JB4 is a piggyback tuning system where flash tuning is changing the code on your cars computer directly. Changing the code on the cars computer is blocked currently and when its unlocked some people won't want to do it since BMW can always see its been flashed even if you remove it. If you want to make maximum power though flash tuning is how you do it.

IIRC, Dinan only warranties their most modest tunes, at least for prior models. Other more aggressive ones have no warranty. I'm also not sure what the Dinan warranty would actually cover or how it interacts with BMW's warranty. Someone else may be able to confirm/refute.

In case its helpful, a piggyback like JB4 just spoofs various inputs that the ECU uses to determine boost, etc. It's not changing anything about the ECU coding itself. In theory, a piggyback can be safer than an actual tune because the piggyback can't change any built-in coding that protects the engine. But the dealer could detect any irregularity caused by the piggyback; for example, if the stock max boost is say, 24 psi, but the ECU has logged a max of say, 28 psi (as a result of the piggyback), then that could cause some headaches.

Fuel trims can be detected as well.
