Looking for some help/advice on E38 Idle

[edcmat-l1]

I have tuned literally a few hundred C6 Z06s. There's no one in this thread that has tuned more I can almost guarantee you that. The only active member that has possibly tuned more is Alvin. Period. Nothing against the other smart guys here I'm talking about numbers.

I can make that car run near stock changing as little as 3 tables total. And in doing so it will not have that pesky idle-up after coast down. After changing a mere 3 tables, I'll know what else I'll need to change based on how it runs by only changing 3 tables.

You're creating your own problems.

OK, your answers are very confusing. You stated I have tables that are not stock. Yet I changed them back to stock and you are saying I did not?

I have tried to follow your advice and return everything to stock with the exception of the spark over and under speed which had to be changed to stop a hunting idle.

I was straight up with you in saying I changed the Torque follower table from stock , after I had found it helped with my off idle throttle response.

I also indicated the pesky idle issue was there with a stock torque follower table.

I have even provided my stock tune so you can see what is stock rather than reference other 09 and 10 vehicles like you have done, which clearly are not right for my car.

Rather than tell me how many hundreds of cars you have tuned, and that I am creating my own problems, why not tell me what tables you say are not stock in my tune?

That is what would help me right now.

Maybe you could share with us what 3 tables you change?

Really the only 3 tables you need to change to make it run decent are MAF, VVE and BRAF. Granted there's more work to do but just those 3 tables and it will run amazingly well, for only changing 3 tables.

These aren't stock. I can tell without the compare file the enable RPM errors aren't stock.

Looks like some of these have been changed.

but but but... some guy on youtube with 2 tunes to his name says his method is the correct one..

Mr. Hutchings do you know why I pulled you over?

You can't give out the magic 3 for free! I'm citing you for unauthorized exposure to the truth.

Now I'm just shaking my head at you and the other smart ass comments following yours. Why are you comparing my tune to a 2010 Z06? No wonder your finding things different lol

That's a 7.0 litre Z06 file your comparing my tune too. not a 6.2 LS3 which is what I have.

I appreciate any help I can get but I sure don't like getting shit thrown in my face when I'm trying my hardest to follow everything recommended to me despite some of it being bad advice.

Surely you know the difference between a z06 and LS3.

How about you use my actual LS3 Original file which I supplied for comparison and you will find that I did in fact put things back to stock as you recommended with the exception of the spark over and under speed tables to cure the hunting idle and Minimum and start up air flow has to be changed as well due to the increased air flow from the camshaft.

I have changed the torque follower tables ill say it again, the idle hiccup was there when the table was stock so I don't believe that to be the issue.


I have made sure proportional and integral airflow tables are stock along with the over and under speed multipliers in the adaptive idle are stock as well.


Lets start over here.

I made a lot of changes over the past day or two, so let me re-upload my current tune file so we all have a current version to look at and make sure your comparing it to my actual stock file.

The problem still exists and I really feel the throttle blade is staying open due to the integral air flow in the logs. So I think something is causing this but I'm not sure what?

They aren't smart ass comments. We do like to have a chuckle mid thread here sometimes. Chill Dr. Phil

OK, that's my bad. Here's why I was comparing your file to a 2010 Z06. Granted, when I saw Z06 I didn't look at the engine size.

That's a 7.0 litre Z06 file your comparing my tune too. not a 6.2 LS3 which is what I have.

Here it is compared to a 2009 manual trans 6.2. Same basic tables are not stock.

Because I don't know that your posted "original" file is unmodified. Like I said before I can tell just looking at the RPM error enable that they aren't stock settings.

Ok, It is not my intention to start shit here but My posts are quite clear its an LS3 and its mentioned multiple times, not to mention you even identified it as an LS3 in one of your previous posts I also clearly identified that this is my stock Original LS3 tune.

I'm not sure why my tune says Z06, despite me wishing its a z06 its still the mighty small LS3 lol


As far as what you showed me in your comparison file , the overspeed error multiplier is in fact stock on my current tune, I just checked it so I am not sure why it shows different unless I did not catch it when I uploaded the file?

But we were talking about idle integral and proportional and their respective multiplier tables and you said to leave them stock. I can verify on my tune they are all 100 % stock.

Yes I messed with the proportional and integral error rpm but they are back to stock as well.

One thing I noticed is the throttle torque follower for 4wd low is different? I have no idea how that happened but I don't think my car would even reference that table?

Effective area percentage max needed to be bumped up because of the increased air flow from the camshaft. I picked that up from HP Academy tutorials and have also been recommend to do that from tuners on here.

Startup Airflow and Min air flow also needed to be changed to to increased airflow so they can not remain stock.

Base setpoint, startup, min and max set points were all changed due to the camshaft having to idle at 800rpm as opposed to the stock settings so I believe these are good.


So having said all this , despite the tables all being stock I still have the idle blip, which is what I am trying to fix and looking for some ideas on how to do this.

Tomorrow night I will run another log with everything back to stock as your were telling me to do and I will supply the log, the tune and my original LS3 tune should you wish to compare it.

If I am missing something, please be specific in identifying it for me.

I don't mean to cause trouble but things can get frustrating at times when communication breaks down

Name calling huh? Real cool bud...... Maybe this would be a good time to let you know that your recommendation of changing the over and under speed tables back to stock and moving them over 1-2 columns made my cars idle hunt horribly. I changed it back to my tables which were cut in half and VOILA!! Car doesn't hunt for idle no more.

I’m just biting my tongue holding back the real name calling.

OK so here is the current tune and here is my original tune, check it out. I have no idea why percentage max and percentage brake show differently but they are in fact the same 2.31%.

I will have a log tomorrow night

I'm surprised edcmat has hung in so long. You're painful. Shorten your posts up and include short concise logs instead of banging out tune revision after revision.

I have come to the conclusion that you'll be the last guy on here I take any advice from

Even though he's coming off a little hard in this thread, Nathan is actually probably one of the smartest guys in here. He's not wrong with the log statement. A short log with as many channels as possible showing exactly what's going on is best. Nathan appears to have changed some of his tuning practices as I know he used to recommend things a little differently. I'm sure there's a reason for it. Either way he knows a lot, so worth listening to

[hjtrbo]

That's a shame. Best of luck with your tune.

I sincerely apologize to the rest of you for having to see all this and I really do respect your advice. You seem like a very stand up individual on this site. But one thing I have learned in life is that when someone speaks to me in the manner that he did, I am done with that person, No matter the amount of knowledge they may have. There is no need to talk too or treat people in this manner. We are all here trying to learn things. But moving forward I will try my best to shorten the logs. Although I am not new to tuning, I am new to Gen 4 with HP tuners and I do have so much to learn. My intention is not to make things difficult here for anyone.

I think the way you've been responding to critic and diverse opinion hasn't been great.

You've demonstrated to me a lack of initiative by not trying to blend your halving of the spark adaptive in the narrow rpm range with my suggestion of moving over the spark columns to retain high delta rpm correction. You just fired back my suggestion was terrible. No log, no follow up questions, no seeking of insight, no asking for my tune. Nada
.
By writing me off so quickly you come across to me as narrow minded and not able to easily deal with a wide spectrum of personalities. Are you a Nancy Pelosi fan?...

Let's see if you can get over your bias of me.

You're not taking advantage of your torque reserve by being a pussy on the large rpm deltas. I suggest your air model isn't quite there, albeit much closer then when you started.
