Finally Got My M340i Tuned By Mission Performance

So I've had my 2020 340i for around 2 months and I finally got a chance to get it tuned by Alex at Mission Performance, and let me tell you one thing WOOOOOOOOW!

The power that these cars can produce is out of this world!!!

I went with the stage 2 and was able to keep all original parts in the car, no downpipes or charge-pipes needed just a custom software tune.

I'm going to be uploading the process on YouTube, but for now if anyone has questions or advise is needed feel free to ask!

How did you get a stage 2 tune without hardware changes? Isn’t that bad for the car?

Hardware change no, software mod yes!

And good thing about Alex is that be bought his own m340i to test every aspect of the tune and it's completely safe and works perfectly fine

Gotcha. I wonder why the others have hardware changes then when running stage 2

Well I think it's because there not Alex lol. He has his own specific tune and was actually one of the 1st ones to actually crack the platform in this unique way. And let me tell you something whatever he did WORKS!!!!!!

What's the power difference? If unable to quantify it, what feels different and how does it sound, did you do the burble option or no>?

As I understand it when Mission Performance/Alex delivers a tune (whether it be Stage 1 or Stage 2) he will take into account the following (other things as well)
  • are you running only 91
  • are you running 91+E85 or 93 (or better) on occasion
  • do you have a downpipe

Ideally you would be running 91+E85 or 93 with a downpipe for maximum performance. However if this is not your reality a stage 2 will auto adapt maximize your vehicle's performance (vs stage 1) while always keeping the factory safeguards in place and the vehicle operating within safe parameters.

I have been running a Stage 2 + Tranny tune on my 340 for almost 20k miles on all stock hardware. And I look forward to transferring my tune to my M340 when it arrives. I typically do my best to run 91+E85 in my tank but when I don't have access I simply drop 91 in and go - the tune auto-adapts. I have not been nice to my car in terms of the abuse it sees at BCCA AutoX events, and BMW club canyon runs etc...and it hasn't skipped a beat.

Alex really is an amazing guy to work with, a genius tuner and a fine gentleman. And he is not a virtual company he is a brick and mortar based in the US (if you care about such things) which makes pre and post tune support pretty easy for those of us in the States.

Anyhoo, hope this helps a bit - I don't have any further information - my limited expertise has now been exhausted on this subject

chenry Thank you. That makes sense now. I always thought a stage 2 tune required hardware changes as well. I thought if hardware changes weren’t involved, it was probably stage 1.

And yes. Brick and mortar is very important to me. If only I could find a brick and mortar place that did reliable tunes for the G20 330i.

Some dyno results are published on their website here:

https://missiontuning.com/bmw-engine...lash-tune.html

You can stage 1 and stage 2 on 91 and 91+e85/93 for comparisons sake :-)

The power difference was around 130-150 of torque increase and about a 100-125 hp gain to the wheels when mixing E85 and mannnn does it feel like a completely different car!

Wow, couldn't have said it better myself brother!!! And you are going to love the M340i when you get it

Thanks - yes can't wait for the M340 - glad you are enjoying yours. I have spent enough time in them (stock and tuned) to know I am already in love. Just stoked that the MP tune is transferable from the 340 to the M340 by simply paying a transfer fee

I'd have it already BUT I have to factory order to get what I want and I now have to wait for the 2021's. But it's okay my MP 340 is still a very nice place to be

I found the linear power delivery to be amazing - it's like a stock car but much more (so so much more). Just pulls like a freight train and never gives up

Does either the tranmission or engine tune make the car more jerky in sport + or does it feel the same with respect to that nose dive feel when letting go of the throttle? Also, how does it sound versus stock?

sorry if I wasn't more clear - the transmission flash is presently only something MP offers for the 340 not the M340

Does this mean he is just relying on the DME to pull timing?
How does it "auto-adapt"?

Hi Nugget
Didn't want to ignore you quoting me but I don't have an answer for you. Sorry I'm not technical enough to answer that question (not even close)
For anything technical regarding MP I will always direct people to Alex. Maybe give him a jingle and let us know what you find out?

You do realize that if timing is retarded too much it can literally melt your exhaust valves, turbine wheel and cat? Of course there is EGT failsafe logic embedded, but this "adapting" concept is bs honestly. Knock sensor is not for "adapting" for fuel. It's there to make fast corrections POST knock, reducing cylinder pressure and temperature for a short time, not BEFORE knock events.

gents - let's not go down the rabbit hole and hijack OPs thread because this admittedly non-technical guy (Me) inadvertently used the wrong term to describe something.

Perhaps i should have not used the word "adapt" didn't understand the ramifications of doing so was just trying to describe the flexibility I enjoy of being able to typically run 91+E85 (or 93) but 91 if i choose to without concern.

Sorry all :-)
