Just let me know what images or whatever you guys want to see and I'll get them posted.
You guys are very helpful with this. Thanks.

It just looks like your MAF Frequency Labels don't match your Tune Labels. Your log is every 400 Hz..Is that what you want? When you copy, paste & multiply you want your labels to match. Just keep that in mind.
My personal preference is the most recent Tune & Log. Unless one is highly skilled in posting attachments, a lot of data is missing.
I think you have 90% of this down..just a few outstanding issues. Its good you have the mechanical skills to fix your vehicle.
Post up your most recent Tune & Log when you get your mechanical issues straightened out..
I just checked, it looks like in the tuner tool the maf is labled every 125 so I'll change it to that. But it looks like I have to enter each one in the Row Lables.Quote:

Up here there isn't really anyone that does anything with these LSX engines. Let alone have and run one of this level. So I have to do things myself and if I don't know I learn it. Also it's nice having 2 cars so I can take a part off of one car and try it if I need to.
My tune isn't going to change until after I can get a clean log and I can start copy and pasting. But I'll get a new log up after I get the new alternator on it.
You don't need to enter each label...
Goto table B5001, click in upper left corner, then rightclick->Copy With Labels...
then in map Row and Col tabs click Paste Labels.
Hi Shawn,
Attached here is a new calc_pids.txt which replaces CALC.PE with CALC.CL just as we discussed today.
Edit: I found an error due to my editing skills :doh2: (== should be =), so I corrected and re-attached the file.
Update: Shawn has updated the calc_pids.txt file in post #1.
All of the calc_pids.txt file have been updated on Page 1 of this thread: http://forum.efilive.com/showthread....l=1#post135867
The changes allow for a more precise definition of closed-loop vs PE. The only time a user should encounter trouble is if they have changed their PE EQ to 1.00 (don't ever recommend that) or changed a majority of Table B3605 to read EQ's of 1.00.
Otherwise the Pid is a very accurate definer of closed-loop.
The Tutorial will take some more time to update.
Thank you for your patience.
Shawn, Thanks :cheers: I'll sanity check those later today.
Shawn, Joe, did the other calc-pids get updated? Such as the veiw afr set, and the one for earlier OS?? I still like to use those, but if they are not the most up to date, I wont.
Yes. All 3 got updated on that page..
The CALC.VET Tuning Tutorial has been updated.
1. calc_pids.txt file (and images) updated to include newer Closed-loop Pid (Pages 4 & 5).
2. Typo HO2S11 changed to HO2S21 (Page 5).
3. Final Pid Selection Image update (Page 6)
4. Tight Filter Image Updated (Page 10).
5. Closed-Loop Filter Image Updated (Page 11).
A few Notes..The CALC.VET Tuning Tutorial is a volunteer effort. Author is WeathermanShawn with major contributions and Editorial review by Joecar.
Originally the Tutorial was not to be published until October 2011. As a convenience it was released April, 2011.
The Tutorial has not undergone final review..there may still be further enhancements of Pids, etc to help streamline the process. As a volunteer effort (unpaid), please keep this in mind when suggesting improvements, additions, corrections, etc. It is somewhat of a meticulous and laborious process to update the Tutorial..so we are trying to keep changes to a minimum.
Thank you for your understanding and patience.
Enjoy your Tuning!
..WeathermanShawn..
Thanks Shawn :cheers:
Pics of maps look good :cheers:
I've been reading thru and sanity checking everything.
For the 97-98 pid selection CYLAIR_DMA and DYNCYLAIR_DMA are not valid pids. Are they required? All the other pids validated ok.
No those are not required, we use them simply as a reference to compare MAF and VE.
Edit: Shawn passed away on this day, we are all very saddened by this, please see the link on post #1.
Hello everybody,
Attempting to tune my first LS1 for a workmate so be gentle :grin:
How do I get all the Calc Pids to come up when I BBL. I have put them all in with S+T and did a short log but the calc pids didn't come up when I opened it with the scantool. I am attempting a Mafless tune on a Holden VY Commodore. OS is 129003. I will be going back to CL running STFT's if that is possible??
Attached is my Auto VE tune and a short log. I have put a screenshot of my BBL setup page too

Thanks in advance

Hi Ben,
Remove the =None from each of the calc pid names shown in your pic.
Ben, since you're in OL then you will use WO2BEN only to correct the VE table.
Thanks Joecar.
I took away the last bit and it all worked fine.
Cheers
Ben
I figured out what was causing lean numbers in the logs on my car. My fuel pump was failing and has failed. So I'm waiting for the new one and get it installed so I can try to start tuning again.
Let us know how you go... :)Quote:

In a nut shell i have NO idea what im doing, as far as tuning im trying. That is, just trying. I have followed the layed out instructions and right now i am at the Filter part. What do i want to filter exactly.
Any help would be appreciated, even if its just someone saying, get off my butt and figure it out.
Dustin
I must be retarded because I can't figure out how I get from recording a log to getting the calc.vet map. I have searched, and I can't find anything that tells me what to use to create the map either. Can someone please point me to something. I'm lost here. It's information overload!
Go to the first post and at the bottom of that post is a link to download the CALC.VET Tuning Tutorial. Under Item #3 at the top of the page in bold lettters is:
CREATE CALC.VET {B0101} MAP
Follow the 15 steps. You'll be good to go.
Thank you!Quote:

So to complete step three from the screenshot on the first post of this thread, once you have populated the table with your data after you log your drive, you go to the filter settings and make a filter you can call CALC.VE so it's easy to remember.
On the maps tab, click edit filter settings (Ctrl+Alt+Enter), click new, enter CALC.VE as the name and click ok.
In the dialog box, you should see CALC.VE at the top, now you want to give it the conditions to filter out.
Under Filter control select "Exclude data frames" so that it excludes all of this garbage from the data you mapped. Your first parameter can be Engine Coolant Temp and make sure you use the same units you logged (F or C). Filter type should be "less than" and then enter 176 for 176 degrees F. "join using" AND or OR can only be changed after you add it, so click add and you will see your condition listed in the white box at the bottom. You can change the condition to "OR" once you have set them all up.
You want to filter 5 different conditions out of this data so keep adding the other 4 just like above ie. coolant temp greater than 212F, TP changing more than 5% per 100 MS, RPM less than 800 as well as Lambda greater than 1.06. Use text at the bottom of the screenshot to verify you set them up correctly.
Click each one on the list and join it to the next by selecting the "OR" button for each condition so that it looks like the screenshot.
When you click ok, it calculates the cell contents but it filters out and excludes all data where coolant temp was less than 176F or greater than 212F or TP changed more than 5% per 100 MS or RPM was less than 800 or Lambda was greater than 1.06. (you may have to click the apply filter button to the left of the map "A" button.)
You can change these settings as you desire, for instance I had a ton of data so I used 10% per 100 ms TP change to get rid of even more data that may have been skewed from jerky throttle movements, but these should do the trick to get you onto your next step of copying this table into your VE table and smoothing it out.
Many thanks to Joe for helping me get this far, I am still new to this like you are, but he and others have spent a lot of thankless time to help us guys understand these complicated techniques.
EDIT***I was working for days off of the old tutorial included with my software:doh2: If you use the tutorial at the bottom of the original post you should have a MUCH easier time figuring this out:)!
John, good write up on filtering :cheers:
No problem, glad to be able to give info for once:) I'm getting it, slowly but surely. Oh, I found a dead cat in my airbox last night. Okay, not really a dead cat but a mouse nest or just a big bunch of random leaves and an air filter that probably hasn't been changed in this decade. I just bought this truck for this project and haven't been through it much yet, lots of maintenance catch up to do. Do you think that could have been the reason my logged VE was so low? Made a big dent in my Map compared to OEM. Thinking I would make another log tonight, I have a new cold air intake for my other truck, I put it on for the time being to learn how to do this. If you have some time can you look at my tune on the other thread? I am worried about how lean the truck was running during my last run and want to fix it before I go out again. Any ideas?
Yes, rodent nest is a restriction to airflow... especially if it causes a significant drop in MAP at WOT compared to BARO.
I couldn't look at your files today since this PC does not have the software installed... I'll take a look later tonite or early tomorrow.
Many Thanks!
can someone please help me out? I'm very much a beginner at tuning trying to do this calcvet thing, I have all the pids selected and maps made but when I log & then go to the calc.vet map its just got 0.0 in all of the cells. What am I doing wrong?Attachment 11755
The log file needs to know what size your engine is to calculate VE%. With that log file open click Edit>>log file information and select your engine size. You may need to save, close, reopen for it to take, I got lucky on that step.
Make your life easier by changing your units to G*K/Kpa instead of VE%. Also make sure you are working in EQ ratio (which from what I gather is the inverse of Lambda).
thank you... I had set the engine size but didnt try saving closing & reopening that did it, thanks
Im new to this CalcVet can somebody check out my log and tune see if im doing ok for a newbie
The roads where water so i baby the car loging. Tomorrow we will be doing some WOT logs

Is that .tun file the before file...?
The log file produces maps which look correct.
Yes joecar its the tune i logged with . i need to do these 1 thru 5 setting changes then log for 45 to 60 mins right .
1. B0701: Disable Catalytic Converter Protection
Insures accurate stoich and PE mode/WOT Fueling
2. B0120: Change RPM Threshold for Airflow Calculation from 4000 to 400
Eliminates any Airflow Correction from the VE Table
3. B3308: Disable DFCO: Change B3308 (M6) to 140C Change B3313 to 140C
Accurate fueling computations
4. B4105: O2 Switch-points to 450 Millivolts
Smoother MAF & VE Table
5. B3618: PE Modifier Based on Rpm (EQ): 1.16
the tune is before the log . i was going to go a better log before editing the tune. i think tomorrow we will be able the do a 45 min to 60 min log .
Ok.
Just done done a Calc VET and things look good except my Idle, my idle is rich when cold, around 12.5 then goes up to around 14.5 when warm. I've also noticed that when slowing down my revs drop quite low but the motor doesn't stall. I didn't think a Calc VET would affect idle since you filter out cells below 800 rpm, I do see one cell at 800rpm-60kpa. Do I need to re tune Idle, I've also attached a copy of my Calc VET log.
Thanks!!
