Firmware/Software Versions

horsepower_and_hounds · 04-24-2021, 05:42 PM

Wow I am behind.... MY 4/2014

I just downloaded the current file (UPD09051) from the BMW server and tried to do a software update and it deny's me. Guess my old horse is as best it can get...or I broke something when I coded it

I had an issue with a leaky injector on my 2018 M4 Comp. I took it to the dealer and they repaired the issue. I took the car back and felt the cars driving dynamics completely changed. it felt detuned. Almost like they forgot the comp tune.

Sport+ throttle response felt less sensitive, the car up shift faster, and it felt less slippery, even with MDM. It seems like if you roll on the throttle in light to medium press, it takes off smothly, less wheel spin, but it begins up shifting as soon as you back off a bit. I also noticed almost like, second stage response. If you smash the gas it then downshifts, and runs out the gears, the throttle response is very sensitive at that point. Almost feels like the previous sport mode. It did make the car more drivable in sport+, but that's why sport and comfort exist.

Previously my sport+ mode the throttle was twitchy, and the car waited to start upshifting for a munch longer time. It would loose grip with MDM on. The car just felt more dramatic.

the dealer said it did not update the firmware, at least the tech didn't note it. So im very puzzled about the change. My friends also noticed the difference. So im not going crazy. At least not on this one.

Is this what the firmware changes discussed on this thread did overtime?

It sounds like your firmware has been somehow updated. The behaviour you described sounds like my car's in its latest firmware update. I like it as it keeps me calmer when I'm in the car

The tech and the shop foreman test drove and said everything is okay, and I'm running the latest firmware. I asked the service manager, to find out how the car was update to the latest firmware, since the car was only serviced there, and no one supposedly updated the firmware. From, my understanding they should be able to pull the firmware at manufacture, delivery and current.

Any idea if the firmware can be updated over the air? So if a SEL is thrown the car does an update to try and clear the SEL.

Have a 2018 M3 CS and took my car in for service and asked if I wanted to update the firmware - anyone with a CS can confirm whether it is worth updating the firmware or best kept as is.

Ajeje · 05-26-2021, 11:44 PM

very interessed to update istep

actually mine is the F020-16-11-502 and on ista i see that can updato to the F020-21-03-520

already read previus pages but coding like gts etc remain or need to be flashed again?

cliffordm4 · 06-20-2021, 02:42 PM

Drove my friend's 2020 M4 Heritage and my 2018 M4 ZCP back to back and noticed an immediate difference. My car almost feels down on power compared to his. 1st gear on the 2018 is completely nerf'd -- feels like less boost and power. Both cars are 6MT.

If I update my firmware, would it prevent me from tuning the car via OBD down the road? Would it simply require the bench unlock or lock me out entirely?

Anyone know what the latest firmware version is now for a 2016 M4? (Currently i am running F020-18-03-530)

I was just about to post the same question, 2015 M3.
I’m assuming I’m WAY behind, as I’m running F020-14-07-501.
Anyone know the latest I can upgrade to?

You quoted the answer to your question.

f020_22_03_552 is latest for all F2x (excluding F25)/F3x/F8x cars.

Ah thanks. I wasn’t sure if m4 VS M3 had any significant differences when it came to SW versions.

Is there any way to see the changes in I-level upgrades? I just updated to f020-22-03-552 from f020-15-03-503 and the car definitely feels different. It could be a placebo thing but the car drives a lot smoother.

No. There is no changelog.

I had the latest software put on by a BMW dealer and its F020-22-03-540

Not sure what the last 3 numbers represent or if it even means anything (552 vs 540)

Your dealer may still be on F020-22-03-540, but the latest from BMW AG is F020-22-03-552:

Dealer has not updated their ISTA yet to latest.

Can you get what version of firmware your in via one of the menus on the ECU?
