Is NBTevo_O18184l still the latest I-step version - mines pre LCI ?

[NJ Drive]

Anyone know of any significant differences between O18092l and O18184l?

[Chasing Dreams]

Steering also improved in my pre-LCI after the software update last Friday.

Hi guys, I was trying to find this in the earlier threads, but how do I check what version of istep I have?? Send help! Thank you!

Got the car back last Friday. I can confirm that MDM is much more playful before stepping in to save my life. I'm not even sure it even stepped in, I didn't notice any flashing on the dash despite going fairly sideways.

PDC actually stops beeping at you when you put the car in neutral (6MT)!!! Had to roll forward slightly before to get PDC to shut up.
Steering feels tighter, and a tad heavier in sport+ than before, and I also want to say ASD is not as obtrusive as before but I don't have any hard evidence to support this.
Burbles are definitely present and accounted for, although it did take a bit of driving for them to show up.

Overall, I really like the update. PDC behaving correctly is a win by itself.

Free update under warranty or did you have to pay ?

[Altra]

I managed to get it covered by warranty. Showed em the picture of idrive with 'no display'. They held the car for a couple days for 'testing' but eventually did the update.

Glad that helped!

[Altra]

Yea!! I almost thought they were going to deny me since they held the car for a couple days....guess they were just really busy?
But big thanks for posting that picture! Pretty sure I would've been denied without it.

just got my update done. It's now "O" something. I came from original version, car is MY17 but delivered late in 2016. Was J163831 previously.

I finally got the update after trying twice with the dealer before. My head unit had gotten itself into anti-theft mode and they ended up replacing it and updating the entire car.

I can't say I notice a difference in the steering. The PDC definitely is improved (6MT) and stops the infernal beeping immediately when put into neutral. As others have said, that's worth the price of admission right there.

But I absolutely positively notice an increase in torque. I wanted to baseline as well as I could prior to the update because of the earlier "conversations" about the placebo effect. All mental, no Dragy or dyno. But let me just say that traction was not an issue before (both with stock and BM3 Stage 2 tune; I have a catted dp) and that's now changed. I can break the tires loose where I couldn't before. not that I hadn't been able before, but that it was more difficult. I had questioned my launch techniques and skills before, but it's a lot easier to bust it loose now. Don't know what to attribute it to so I won't speculate. But it's different. I haven't yet re-applied the tune.

Using the BM3 app, I had re-set adaptations before, and had not noticed a difference. So unless there is some other set of adaptations that are re-set with the new flash, I don't believe that's what's driving the change.

Needless to say, it's a welcome change and I'm happy with the results. If you have an older istep (remember mine was J) and can get it updated, I'd highly recommend. I have a ticket open with BM3 for how to deal with the new ROM and will re-apply Stage 2 once I get that figured out.

Did you flash to stock and lock the DME before the dealer upgraded? I'm friendly with my tech and he said he would perform the upgrade but I'm hesitant because I'm also running BM3 and don't know how that effects things.

Yes, exactly. It's great that you're friendly with the tech but he should insist that you revert it to stock tune and lock it again. Once you get the update, according to BM3 you can just go back in and re-apply the tune again. That's the ticket I had open with BM3, as in another thread I was told that I'd need to clear everything out of my account so I wouldn't down-rev the ROM to the original istep. Seems like that's not the case but I want to get one more round of clarification.

My understanding was that flashing BM3 after an iSTEP update would work fine, but your DME would then be back to the same state it was in before, and would show to any system reader that the DME version was out of sync with the iSTEP you have.

My other concern, was not so much if I could flash BM3 after an iSTEP update, but how I could go back to stock and lock at the correct iSTEP version if I wanted to. I plan to go back to stock and lock every visit to a dealer, just in case they want to do an iSTEP update for any reason, and I'm concerned that their update software might fail if the DME is out of sync.

I'd heard that each map, even the OTS ones, are based on a particular stock map, so if you do 're-start' your account, all of your saved maps will be lost.

Do let us know how you get on with PTF; I'm really interested in this myself!

Yup that's the case. Unless they made changes to always flash a "OTS" based on the current ROM version of your car.

With that said, the differences between a 2016 & 2017 M2 DME ROM is very minimal. But it's definitely a different ROM base.

Any car produced after 2017-03 should see no difference in the DME after ISTEP update.

M2 only has 2 ROM's

I'll update the other thread when I get back the answer. Looks like SeanWRT is correct though, so I'm holding off on re-flashing until I hear what they recommend.

K9GunSlinger : Yes, that's the version I received last week.

Yes, so like I said, there are two concerns:

• Will i be missing out on some newer DME features / performance if I'm using a BM3 map based on an older build?
• When I flash back to stock and lock, will my DME be out of sync with the rest of my vehicle

You addressed the first concern; as long as you have an iSTEP after 2017-03, you'll be on the newer of the two M2 DME ROMs anyway.

What hasn't been addressed is the second concern. It should be pretty easy for PTF to add an additional backup and restore option that backs up the newly updated DME so that it can be restored and locked before a service.

This is my my software I think, what's the latest update and what's been updated? , my car is going in for the mpe next week and I might try to get them to flash the update if I can one time while they have the car, I really really really don't want to lose the mdm pops and bangs :

Hey Guys,

Quick question, will the software updates be any different for those of us with PRE LCI cars?

Another Member said he just got his updated and his software now says "NBTevo_E16072A"

I took a picture of my nav screen before I dropped it off at the dealership and it was "NBTevo_E16202A"

I don't know how the numbers work if his is actually "updated" or maybe they only did a partial...so if ours is both PRE LCI (2016 M2) will we never have the "O" version of the update and ours will always be "E"?

[K9GunSlinger]

just Asked my service advisor if they could provide a picture of my updated Nav screen to check the software update version this is her response:


“The vehicles software is not read of that unit, that picture shows your navigation units software. Their is no other way I can show the vehicles update. If the vehicle is not tuned and your on down pipes if the vehicle throws a malfunction code that is definitely gonna be due to fuel cut since the vehicle is over boosting due to the excess amount boost cause by not having the back pressure of the cats that where originally on the vehicle. You can definitely over boost and blow the engine if your running down pipes and the vehicle fuel trims not being adjusted to that setting. The vehicle may act haywire due to the excess amount of fuel mixtures due to cats missing’”

Your thoughts?!

Is it possible to do a full istep update with just a battery trickle charger? I have the CTEK MXS 5.0
