No worries, take your time...
In the map properties, on the Data tab set Precision to 3 or 4.
In your map, I see some values creeping too far from 1.0, namely 2.2, 4.0, 2.2, 1.8 and others... your MAF table can't be that far out, post a pic of it.
Post new log and tune files.
Do both of these:Quote:

alright i finally got back around sorry for taking so long. what all am i doing wrong here??
No worries...
post some screenshots of the steps you did...
i took the above maps created by the calc ve tutorial but i think i must have something wrong in the pids or the maps... can any of you view my created maps through my log i posted?
Something is wrong with the values of the pid EXT.WO2LAM1, they should range from 0.5 to 1.5.
Which wideband are you using (did you say LM-2)...? Something is wrong with it.
Can you log it's 0-5V analog output to see if it correlates...?
yes it is the lm-2. i am trying to trouble shoot that issue. do i need to be looking for a problem with the wideband controller itself or something incorrect with how i have my scan tool setup. sorry i feel so dumb on this. i am not understanding how i am getting wideband data on to the scan tool yet that one pid is showing what it is.Quote:

I just clicked on the calc_pids.txt link at the beginning of post #1 and it opened ok in Windows Notepad...
when you click on it you want to save it to your PC (i.e. do not open in as an EFILive file).
okay... duh its been a minute since ive been at it. it kept opening it with efi live...Quote:

Ok, you're running OLSD (no MAF, no LTFT, no STFT)...Quote:

i.e. just correct the VE table, use the pid CALC.WO2BEN instead of CALC.SELBEN to correct the VE.
I must be missing something. When I copy and paste the calc_pids-2.txt I cannot see the additional pids CALC.LTFT CALC.LTFTBEN CALC.VE_Table. can anyone enlighten me?
You have to name the file exactly calc_pids.txtQuote:

the pids defined by this calc_pids.txt are these:
- CALC.DAT
- CALC.LTFTBEN
- CALC.WO2BEN
- CALC.SELBEN
- CALC.VEN
- CALC.VET
- CALC.MAFN
- CALC.MAFT
If you download it once you will see calc_pids.txt, if you download it again you will see calc_pids-2.txt... it's what Windows does.
You can do what Joe mentioned above, you may need to replace the existing calc_pid text file. Usually Windows will ask if you want to "Copy and Replace" and you should select yes. Usually files from Internet Explorer or Chrome default to the c:temp or a downloads folder. So just make sure it is going to the path Joe posted above.
Or you can make a copy of the calc pid text file that is posted in this thread - call it something like "Calc_PID for CalVet", and then copy and paste the content (text) into the calc_pid file in the user configuration folder. I have several calc_pids files depending on what I'm doing.
As long as you get the content into the calc_pid file in the user configuration folder, you should be good.
Thanks Joecar and Lastcall. I copied the files directly to the pids file instead of the user configuration file. I should probably wear my glasses more often.
Good deal, glad you got it figured out.Quote:

No... it replaces AutoMAF (but using both WB and LTFT), and calculates a VE table from it.Quote:

A large part of tuning is knowing when to use which method, and to understand the method (and its implications) sufficiently well to get good results.
Hi guys, I'm fairly new to the EFI tuning world. I'm tuning my slightly modified 2004 GTO, and I'm having issues with CALC.VE and CALC.VET. I've attached my latest log, tune, and calc_pids files. Whenever I paste (with labels) my new VE values (in g*K/kPa, or %) I get some really weird values. Any idea what I might be missing here, or is my factory VE table off this much? Any help would be great!

Can you post screenshots of what is happening...
I now use Calc.VET instead of Calc.VE: Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log)
Try the attached tune.
Hints: use more throttle, try to make smaller motions on the throttle.
Question: did you change your MAF plumbing air duct...? Post pics.
Thanks Joe!
I've attached screenshots of my B0101 and B5001 before and after using Calc.VET, as well as the tune with these changes. I started with Calc.VE a few days ago, but after I got wonky results (similar to what I see with Calc.VET), I found this thread. The two big things that I'm unsure of are the spikes in the B0101 table, and the drop in the B5001 table. These are following the first post's tutorial, and making sure to apply the Calc.VET filter.
I'll give your tune a shot and get some drive time logged. Should I shoot for more RPM, or just try to get more load on the engine? By smaller motions, do you mean accelerate more slowly and get to higher RPMs, then hold it with steady throttle input?
I have changed my induction, I've attached a picture of that as well. The main changes are an XAir intake and fast acting IAT. I do have aftermarket headers (short) and JBA mid pipes (catted).

I looked through your tune, thanks for running through that! I think I understand what you did. It looks like you took out the PE enable delay, made the PE modifier 0.85 across the board, and modified the TPS % for PE enable. I assume the B3615 modifications are based on experience?
For the B0101, did you mainly smooth the lower RPM "dip" it had? I think that makes sense, I actually had an issue under higher load, lower RPM acceleration where the engine would lean out for a second or two. Did you do a decent amount of smoothing on the B5001 and lower it a bit? Sorry for all the questions, I'm an engineer and can't help it!
You need more load, and larger throttle opening... but try to keep throttle smooth (less jerkiness), this is hard on the street... dragging hard on the brakes for a few moments will help increase load.Quote:

I suspected your MAF duct had changed (see my comment below regarding B5001)...Quote:
If the driver does not realize the PCM is in hot mode, then PE should still kick in as normal, there is no reason to hold it off.Quote:

Yes, the trend was downward a bit, so I carried it up.Quote:

No worries. Me too :)Quote:

Alright so I loaded your tune and did some logging. I did three logs (really just two, the first was a quick spin around the block). I wasn't able to get some good time with high load/throttle opening. So today on my way to work, I used a stretch of fairly flat highway to log high load/throttle opening. I got a log there and one back. The log there seemed to give me pretty good data. It looks like my B5001 wants to come down a hair, and most of the data for B0101 wants to bump it up a bit. Can you take a quick look and make sure I'm on the right track with my thinking? I've attached my later two logs, and a modified tune based off the first log.

just a quick question setting up the calc.ltftben {b5001} map, why is engine rpm used in the column tab?
Basically its just a placeholder to get the map to fill in that column. Pretty sure you can use almost any selected PID, but RPM for sure works.Quote:

I'll take a look at these tomorrow, sorry I'm running behind.Quote:
