Version 1.5 is coming...see the teaser here: • Get ready for a new ag... Once that is done then I will work on version 2.0. Here is the link for 1.0: drive.google.c...
I wish I could post a couple of pictures of my VVE tables before and after using this. Works beautifully! I spent about an hour running all my zones through the software several times (probably 7-8 times for the bad ones), went out for a new log and BOOM, all within a couple percent. You do some awesome work and have helped me tremendously in so many areas of tuning. Thank you!
Tried this today along with the MAF tool using the formulas for DA. Looking promising. While the MAF tool was easy to follow, I got lost somewhere along the line using this. I'll have to re-watch again for the 4th time and see where I ran into an issue when I have a bit more time. Appreciate you taking time to do this.
Good to hear! I'd love any feedback or suggestions to make the tool better. I have a few more features I am going to add before calling it a wrap on version 1.0. And then work on 2.0 begins!
This is a GREAT TOOL!! How awesome for you to share! Only think I noticed was when I paste in my zones, the zone borders only go up to 1.420, and my zone table goes to 2.98. Besides that, this was a game changer for me. Much appreciated!
Glad you are enjoying it! There should be no limitations on either RPM or MAP/Baro axis. You may want to verify you are copying the table over completely. Otherwise please email me some screenshots and info to help me understand where the hiccup is.
Hope it works out well for you! Check back for updates frequently. It's still a work in progress and I dropped new code today in fact. Please keep in touch and let me know if you have any ideas or errors (hopefully not).
@@SilverSurfer77 Yeah, I checked the drive earlier, and realized you put up a new version, had to shorten my comment before I posted, lol. Pretty stoked to do some more logs and fine-tuning ! This was awesome for my idle so far, since I was able to see and change the results, without flashing a logging over and over.
This may be a dumb question, does this work with the e40 ecm VE? As in, my ecm doesn't have VVE, just the primary VE table under airflow, general. I don't have the zones or coefficients like on the e38s
Not a dumb question at all! The answer is YES you can. In fact, I have switched over from the OEM VVE OS to the HPT 2Bar SD OS and I use this tool. While you don't need to worry about the computer calculating the coefficients, you essentially are doing that manually when you copy/paste special and then smooth and blend by hand or by using the smoothing tool in the HPT editor. So you can use this tool to ensure after all the smoothing you did, that you didn't go too far or too little.
So this will be a long shot. But, I wonder could there be a way to also filter out cam degree position for those of us who have VVT? Say like setting up the VVE filters to also just populate a specific cam position based on the desired angle tables? Mine was up to 24°, but now the btr cam is only up to 11°
You have to do this in the VCM scanner. So for a parked cam (0 degrees retard) you can use the Basic Mode. However, you will need then change the filter in VCM scanner for whatever degrees and then go into Professional Mode to set that up.
Good stuff, glad to see someone improving upon this again. I miss the old BlueCat VVE editor, it was so much better at handling changes to the table. Any plans on adding zone adjustments to help line up zones based on the shape after applying histogram changes?
Work for version 2.0 has silently been kicked off. Upcoming changes will include the ability to edit the zones inside this tool. However, what I am most excited about is the tool will be able to calculate the coefficients itself and include the cell hits for weighting! Which means a cell count of 1000 is less likely to move, while a cell out of 50 will be more likely to move during the calculate coefficients process. Additionally, the tool will self apply the corrected histogram output over and over and calc coeff over and over automatically until the margin of error is reduced.
At this point I've watched most of your videos. I have a 5th gen and been using your tool and it really seems to work very well and thank you. My question is on your MAF video you use a filter to look at torque management and a few other things Do you recommend that use that same filter when doing my VVE? Otherwise you give a lot of great information
Yes I use the same filters in the scanner for MAF and VVE. And you still need to drive with a steady throttle to eliminate any transients as much as possible for best results.
It seems if you go to far it will start to increase the values? Maybe I'm doing something wrong? I have the squelch set at 2 and -2. I start CalcCoeff and you will see values drop off. Do CalcCoeff a couple more times and values pop up going in the wrong direction.. Is this normal?
without a screenshot/video it is hard to say. But what really throws this off is missing histogram cells in a zone. Check out the video I did for Version 1.5 of this tool which shows you new methods to help combat this. The other part that can throw things off is too small of a zone. You need at least 3 rows or 3 columns...the more the better.
@SilverSurfer77 at 1:18 mark you paste data from LTFT + STFT graph, shouldnt be this actually from VVE CL? i compared them both and the data actually differ a lot in them
Whenever I try to paste the data into HPT and click the final calculate coefficients, it makes the entire graph flat with massive spike in the center. No idea why tried messing around for hours with the same result. Any ideas?
This happens sometimes (in my tool and HPT). Whatever combination of numbers there are really sends the coefficients for a loop. It can be an indication that the zone is too small (you need at least 3 rows and/or 3 columns to get the best results, the more the better). If that doesn't work then you I normally just interpolate over that high spot vertically from the last rows of the zone above and below and then re-calc. From there you may be able to redo the initial calc or just adjust by hand.
Used this with good success over the weekend on a Gen 4. I like that is displays the zones and predicts what your new errors will be (handy!), but I am still trying to understand how to move the zone boundaries as a strategy to get a better map. I'm stuck right now where no matter what I do when the software calculates coefficients it drops huge error in right on an RPM column so I end up with this jagged spot in my map. I will continue to study and try to figure out how to fix this.
I must be doing something wrong as it won't let me define zones. I also am not sure why you would put the data back into it so many times. Do you have any videos explaining stuff like this for beginners? I watched your maf videos and I believe i got that correctly. All the logs look good.
You will have to be more specific about it "not letting you define zones". Is it throwing an error? Does the pop up window appear? Did you unplug a secondary monitor and windows displaying it on the imaginary window that you cannot see? When this video was made, I did not have the ability to calculate coefficients. So the power of the program was to calc the coeff in HPT and then copy the results back to the program and it would compare the new VVE shape to the old one with the histogram which tells you if you are getting better or worse. However, I figured out how to calc the coeff within my code and that was released under the v1.5 update. I made a video for that with the newer functionality here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nnA1rA5QQ7A.html However, this video goes through all the required basic functionality to understand how to use the tool. I will admit this VVE business is not for beginners and this tool is not really a shortcut to success. It is intended as an aide for those how already know how to shape VVE and want to be able to do it faster and reduce the overall iterations (drive and log) to get it correct. Many people have reached out to me for help, I do charge $100 and for that you get your own personal private training RU-vid videos with me narrating your logs and tunes and using the tool to shape your VVE. As long as you send me logs and have questions we will keep going. Generally most people "get it" after 3-4 logs and videos. But I have done around 5-6 iterations in the past as well. If you want to go down this route just let me know. Otherwise, feel free to ask questions and I will do the best I can.

Any chance you could put an undo function in this? In the Paste Special output tab I was playing around te the fill in missing data, No way to undo it once it’s applied. Btw great program. I was doing something similar in excel without your skills. He’ll just being able to see it overlaid on the zones is awesome. Thanks.
Yes. However, VVE is primarily used during throttle transitions. It's also heavily used at low RPMs where the MAF is less reliable due to cam reversion.
Is this good to use with your "My Version for MAF and VVE at the Same Time" method? Input the corrections from your charts into the VVE Assistant and go through the steps?
The link is to my google drive...so as long as google.com is working it should be fine. Recently another lad had issues and it turned out it was his anti-virus software.
@@SilverSurfer77 Well I spent the day to watch your videos, but can't find any info for setting up the scanner/graphs. The tool looks awesome if I could find info how to setup the scanner for a 5gen E92 ecm on a LT4 engine?
@@RichieYes That is usually the stuff I charge for...not to tune your car per se, but using your logs and tunes to create personal private youtube videos to teach you. And I do send the tune when I am done, you retest/log, send back, and I make another one, and so on. You learn as I go through it.
as far as the vve pe and vve cl math goes and histograms. one will paste with no issue into the vve tool the other will not because it says something about looking for a percent instead of a decimal. i guess my question would be which math/ histogram would i need to use to more effectively tune the vve table? or would i use one for the closed switch and vve pe for the open switch?
If it is complaining about a percent/decimal, then you are pasting the wrong data into the wrong section of the tool. Meaning histogram data and VVE data are different things. The other possibility is that you didn't copy with axis from HPT, or maybe you are trying to paste the zones in the wrong spot as well. You should log both CL and PE and paste them both in the histogram tab in the VVE tool. You just have to click the Merge/Average link.
@@SilverSurfer77 ah the merge is what I wasn’t doing, I did every thing right it would let me paste the CL VVE but not the PE VVE. I will try the merge function. That might be my problem thanks
Either use task manager to kill the process for "VVE Assistant.exe" or reboot, and then try to delete the file. It is also built on .NET Framework 4.8 which you should have already. If it does not open then it is a local issue on your machine.
@SilverSurfer77 Thank you very much. Because of you and someone else on RU-vid, I'm getting my 2015 gmc swapped from a 5.3 to a 6.2, with a 6l80e. And big cam and headers, still having a touchy pedal, hopefully it's in the vve table's that I have been struggling with. In the logs, the thing is going way rich to fairly stoic. Also a 2400 stall. That's a bit weird at times with the shifting.
It's available. On v1.6 now. Check for a newer video that demonstrates the Calculate Coefficient functionality and cell averaging. Here is the download drive.google.com/drive/folders/1-Y4fORr6xiAfVSmZkSrXC1tN6y6XbMuR
It depends if you are using MAF and VVE (as designed and used in the OEM format), then the answer is NO. If you are in SD mode, then YES. But really adjusting MAF/VVE to hit a certain lambda is not the right way to do it. You need to adjust the EQ Ratio in the PE tables in the tune first. Then calibrate your MAF/VVE to hit that EQ Ratio target. In normal MAF + VVE mode, the VVE is used during (1) throttle transients (where the MAF cannot respond quickly enough) and (2) low RPMs conditions (where there is a lot of cam reversion that ruins the MAF signal). VVE is NOT used for steady/state or WOT. MAF will primarily be used for steady state and WOT. If you want to dial in WOT fueling, this video will help. I also updated the PPT slides with a lot more info, so be sure to click the link on the video description to see it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xRZaTblSQ_0.html
