My question is why did the DME not prevent the catastrophic failure by cutting off ignition, based on all the (pre-) knock detection, etc.? The safety net was either suppressed or has failed to get to that point…

[sigterm2.0]

I'm new to the BMW platform myself, so I'm still learning exactly how this DME operates compared to the other platforms that I tuned.

I guess my question for those who are more experienced would be what is the max capability of the corrections? Maybe the DME has a correction table so the max retard can be modified? Or, like you said maybe the tuner may have modified the values as a way to try to stop the DME from taking power away (yikes!)?

I don't know what this tuner's line of thinking was, and I don't like to bad mouth people, but in my experience, those logs were telling him that the changes he was making were not right for this setup.

When I get some time today, I'll look through BM3 and see if there is an ignition correction table and if there is, what it's limits are.

This should be a reminder for all of us; just because someone says they're a tuner doesn't mean they are.

Ultimately you have to be the one to understand what your car is telling you, in the logs and while driving it. Based on those logs, during those pulls, the driver should have felt that loss of power and that something was wrong and gotten out of it with that amount of knock, I am wondering why a check engine light didn't come on? You don't finish a pull like that. Especially fourth gear... That beating went on for probably 5-6 seconds, WOT... 3 times...

I'm not really a fan of this "remote tuning". The tuner needs to be in the car, on the street or at the dyno. Yeah logs now a days have a lot of channels to gain information, but feeling the car through a pull is extremely valuable.

Hahaha... sorry for the old guy rant... 🤣😂

I have a feeling your Piston broke before the 1st Log? I can't explain the first 3 Knocks at the beginning of the 1stLog?
With the 5 knock at 5920rpm your Ignition Timing jumps from 7° to 31° at 23psi Boost, at this Point the Piston is broken. Your Tuner will be able to explain why your Ignition Timing jumps from 7° to 31°!

So in BM3 under the ignition tables, as I figured, there are ignition correction tables where you can modify the amount of correction the DME will apply under various circumstances, one of which is full load.

I guess we can speculate all day long but in the end we won't know anything for certain unless you have an editable version of your map. Then you can look at the values in your tables and see what he was doing.

That looks like a good stage 3 pumpgas tune. Who tuned it ? It seems your 98 ron is of decent quality too.

One tip though, if you make a log, no need to WOT before 2000 RPM, that causes unnecessary strain on the drivetrain and turbo
You can just start the log flooring it a bit over 2000RPM when the turbo already is spooled up a little.

And next time add the "msv duration after pi" parameter if you log. That way we can tell how much strain there is on your TU hpfp (if it reaches an angle of 126° it means it's maxed out). Because I'm quite sure this is about as far as you'll go in terms of boost on a TU hpfp even with pump gas. It doesn't seem to really dip under 200 bar though so seems okay.

Overall, looking good!

I saw this in the FB discussions group. I've never recommended him either he doesn't tune the cars he has some helpers do it.

Anyways there are tuning tables that limit how much timing the DME can pull and the stock limit is -10 degrees of timing on all cylinders. Basically in your tune the DME could only pull -10 degrees but needed to pull more. Now the car cannot protect itself and you began knocking nonstop until it blew up.

That idiot fat fingered or had someone else fat finger and requested way too much timing.

Those logs are a pain to watch.

But what kind of tune starts to advance timings >30 degrees from 1500 rpm WOT?

Out of curiosity, could you show an aggressive & reasonable timing advance table vs load and RPM?

No one is doing 30 degrees of timing on these engines. This is the stock timing table. For an aggressive / reasonable table you would start by scaling up the values by 2 in the final column and setting 180 load to 205 load.

As I thought nobody would deliberately request 30 degrees of advance timing unless they want to blow up the engine on purpose. Expensive mistake for the owner of the car if it was indeed mapped like that.

One thing I want to make sure everyone who reads this knows is that you should NEVER go WOT at 1500 rpm. Going full throttle at very low RPM can cause knock. At least that's what I've always heard and read online. Are DMEs so advanced now adays that it doesn't matter, I'm not sure but I'd still advise against it until you see proof otherwise.

Go WOT at 2500rpm or higher.

[delarock]

Guys can you please evaluate my logs ?
Stg 2 ron 98 ( with ron 100 fuel)
Full throttle log :

I have no options for etanol at my country. Should i change map to 95 ron or its safe for engine Why f.e. on 3000 rpm i have much higher corrections comparing to 4500 rpm f.e? I have new HPFP, new injectors, planning to change the plugs for ngk. ( mine are just 4000 km old now )

I don't see anything worrying in your logs, it looks good. Just enjoy your car.

Hey y’all new to the forum just tryna see if y’all can help me figure out why my car might be idling kinda rough sometimes, and the idle speed jumps up like 100rpm sometimes when I come to a stop or when I am parking, goes from 650ish to 750ish. After blipping the throttle it goes back down but not sure why the idle has been weird in general. Lower RPM feels kinda laggy sometimes too and I know most people don’t rock with the burbles but I’ve noticed the burbles have gradually started getting less aggressive and I haven’t changed any settings on MHD. I recently changed the spark plugs out for the NGK 94201 and had them gapped down to .022 like some have recommend, and changed to the Dinan coils. I’ve cleaned all the air sensors I can and completely unrelated but did a trans service recently at like 45k miles the cars at 49k miles and I’m just not sure what it could be cause the car used to drive and idle like a king but it’s kinda lost it’s tone and “umph” the last few weeks. Thinking maybe it could be vanos actuators cause the intake and exhaust vanos are kinda off from the car is calling for but other than that I’m not the sure, was thinking maybe cleaning or replacing injectors cause the car is at 49k miles now, or maybe the 02 sensors are ate up from the burbles… idk but if someone can look at my log and help me out I’d appreciate it����.
Mods are:
Daw 5” downpipe
Mhd stage 2 e30
K&n filter for the stock intake
BMS chargepipes
Dinan coil packs
Stock hpfp (not tu)

Hello all, I'm new here to the forums and to the modding world. I have some logs I'd like to have looked over if anyone is interested. I have some problems with my timing being pulled and I'm not fully sure why. I also notice that my fuel trims are all over the place. Seems like I might have a few issues with the car now that I got it back. I just got a brand new "cast Pure800" turbo installed from WestTuned. I can hear a loud tapping sound that's only audible when rpms increase but not at idle. I'm worried for my car but here are the logs. Any help/feedback is greatly appreciated.

I commented on your post on the fb discussions group. The fact that the first log was at their shop and they let it go with that much timing correction is upsetting. These are not acceptable corrections you need to pay someone else for a re-tune :/

The stft aren't amazing but they're not terrible. +-10 is okay and yours only briefly go above +10

Here are two logs from today.

Hi flow catted DP
BM3 stage 2 91oct

Im in CA but add about 2oz of boostane to every fillup.

Would the ACN91 map run better based on these logs?

Yes, run 91 ACN unless you can spash in a little bit of ethanol with each fill up.

I did a small pull on BM3 stage 2+ multimap set to MAP 3 (E30). I have E50 in the tank with new stock gapped plugs and new coils.

The pull has no timing pull in 4th gear and looks clean up to ~6k RPM. When shifted to 5th in the same pull it has timing corrections across the board - up to -6-9 on some cylinders. Any ideas why this could happen?
