@@bsivley81 Yes I change them In almost every vehicle tune. Power Enrichment or PE adds extra fuel . This can be setup to come in as soon as you reach a specific ( adjusted in the tune) throttle position or torque amount. On a naturally aspirated vehicle the benefits of this extra fuel is that it provides a cooling effect on the cylinders which equates to engine longevity. On a boosted application this is how you control your fueling to maintain a specific afr/lambda value. You want to set this up on a NA vehicle so that it is only coming in when you are on the throttle 2500-3000 rpm’s and up . Anything sooner then that you will be wasting fuel and your MPG’s will significantly drop. On a boosted vehicle you want it to come in a little before you are in boost. I hope this helps.

@@johnathankozloff212 if you are still having issues please message me on Facebook @titantuned. Communication will be much smoother

@@jimmyfreeze3782 it is there as reference. For example if I have a customer that would rather know what their AFR is , it is much easier to just look at it in the channels list then to get a calculator and math it out.

This way will for sure save you time

That’s awesome. It is a small world

So your stft s remain active , I am only turning off Ltft. In the VCM editor make sure you are using “copy with axis” and are selecting the entire “define zone page. Best way to do that is click the empty box at the top left and it will select all for you. I have noticed that sometimes if you try to drag to select entire table it misses a few because it doesn’t always scroll down while dragging. To answer your question, I have always used zones and I can not verify if the tool will work with out defining zones. That might be a question better answered by silversurfer77.

@TitanTuned Hey thanks for replying. So yes my STFT are active using "O2 Readiness". I couldn't get the histograms to populate correctly,. I checked all the fX math and the filter math 6 times (user error 🙃). As for the zone error, I've always had it even without the VVE tool. The error says something like "zones 17, 19, 29 are not supported by the data provided. This is odd when I made my histograms from my VVE tables. I'll message silversufer77 to see what he thinks. I never thought to filter the Histo Tables by RPM until you mentioned it, so i created my own. I made some tables just for Wideband VVE/MAF and STFT VVE/MAF and filtered them using CL active or OL active by RPM via the Scanner like you said. We'll see how it goes. All GREAT information!!!!! Keep up the good work.!!!!

You shouldn’t have to. I recently tuned a 19 Yukon that had a stock variable cam and didn’t have any issues.

I apologize for the long response time. Please check out my website www.titantuned.com In the shop page there is a digital download section. I have everything that I use to tune Gen V vehicles in that section as far as hp tuners goes. I am adding things daily but it is time consuming. I will work on creating a base map for each year engine and trans in the coming months.

I have a part 2 video that goes over what to turn on and what to turn off in the calibration file. Please give it a watch and a like and if you have any questions I will do my best to answer. Thanks for watching.

@@TitanTuned man, sorry to bother you. I ended up going though the comments and seen you posted a part 2 and I watched it. Sorry to bother you. But thank you for your reply. Much appreciated.

No worries. I hope the video helped.

Unfortunately I have not had the opportunity to tune a 4 cyl. Vehicle with this formula, but I would assume that you are correct in your thinking. You would need to change the math formula to reflect that only bank 1 stft and ltft are referenced.

The part one video goes over the filters. If you are not seeing data populate in your graphs, I would make sure that you are logging the correct channels and make sure the math entered and the filters entered are correct.

HPTuners can't filter live data based on time. You need to stop logging, save the log, then re-open the log file and it will populate the data. This only happens when your filters have any sort of time based filtering.

Thank you. The filters that silver surfer uses work great on gen 4 engines but they are not available as a channel that can be logged on all gen 5 ecm controllers, take the gen 5 v6 ecm’s for example. The reason I use those specific filters is because every gen 5 vehicle I have tuned v6 or otherwise has power enrichment as a channel that can be logged. Using the power enrichment filter like I do works just as well as silversurfers , but in my opinion it saves time not having to go and change the filter every time a vehicle comes in and has an ecm that does not support the filters used by silver surfer. Ltft are in the formula to make the formula work whether I have ltft on or off , again an ease of use thing. If they are off they won’t show up in the logs. You are correct , if they are off you do not need to reset ltft before every logged drive. I hope this helps and thanks for watching!

Thanks for the thorough response, you and goat rope garage are the only videos I have seen to date that things are explained and shown to make things easier to understand. I'm actually tuning on a Gen 4 platform in a vette, but this video will work on the Gen 4, but I don't think your filters would work. How do you feel about Virtual Torque Tables and Tuning them? I know you are a Gen 5 guy but it would be awesome to see a thorough in depth video on virtual torque tuning for both gen 4 and gen 5. Its a subject that does not get addressed very often.@@TitanTuned

It depends on what gen you are tuning. The filters I use in the video will work on all v8 gen 5 platforms, some gen 5 v6 and 4 cylinder platforms do not monitor the same parameters as the v8’s do. Silversurfer has a recent video on his channel that goes over the filters to use for gen 4 vehicles. The best thing to do is to enter the filter into the math parameter section, then it will highlight in pink what you are missing as far as what parameters the vehicle monitors. I hope this helps

Thanks, now I'm working in the right direction.

You will still need to input data to the MAF and the vve, but you don’t have to do the traditional process of tuning only the MAF and then only the vve.

@@TitanTuned Got it. Do you make adjustments to the MAF and the VVE on the same drive data, or do you tune the MAF, go for another drive to log VVE, rinse and repeat?

@@cerealkiller19 you use the same drive data , I have another video on my channel that goes more in depth.

The best thing to do is look at your vve table in the editor, then set up your vve graph in the scanner using the parameters that are used on the vve table in the editor. Whichever is on top is your column axis , whatever is in the side is your row axis.

@TitanTuned thanks for the reply. Yea I set it up with MAP info off VVE. I'll give it a go this weekend!

The notes are incorrect but The actual math in the expression is correct

Thank you, just wanted to make sure I was doing it correctly. Thank you for taking the time to do this video! A lot of us need this step by step help @@TitanTuned

He used EQ error and flow factor

There are multiple ways to tune both MAF and vve , this is just one of many. Some are more accurate then others. I am not by any means knocking how any person tunes, however the method that silversurfer published is outlined by the original GM patents that gm uses to calculate airflow. At least that is what I got from reading the forums, there are copies of the patents in the thread, and people that are way smarter then me that have dissected those patents to say this method is at least very close to the calculations gm uses. Again I’m not knocking any particular persons method of tuning there are more then one way to skin a cat. I will say that this method seems to be more accurate as far as calculating vve from the MAF compared against flow factor. I say use both methods and decide for yourself which works better for you.

You are tuning the vve from the MAF compared against dynamic air data. You are tuning both at the same time. You don’t need to do MAF only, you don’t need to do closed loop only or open loop only. In short the only thing you need to turn off in the tune is dfco and cfco (if manual) and turn off ltfts. Then from your drive log you will correct the MAF and also correct the vve graph. I will make another video showing the whole process.

@@TitanTuned So do you ever use the wideband on anything other then Power enrichment?

As far as the calculations and filters go the wideband is only used in the VVE dyn air open loop and the MAF dyn air open loop. And the MAF and VVE dyn air closed loop are used when dialing in closed loop(stft’s). Doing it this way (both simultaneously ) ensures your closed loop fuel trims (stft’s) are dialed in as well as the open loop side of things. If you wanted to only use your wideband to tune the entire range you could . You would just need to use MAF dyn air open loop and vve dyn air open loop, and you would need to delete the rpm > or < 2500 aspect of the filter (it is the very first variable in all the filters) Doing it this way may take longer to dial in because you would be fighting stft’s. Unless of course your setup is open loop only then this would be the way to go. At that point you would need to make the necessary adjustments to be in open loop all the time. With out getting too convoluted, I hope this answers your question

@@TitanTuned Thanks man. Just wrapping myself around Silvers Method and Matts Method vs what I usually do which is fail either and tune vs EQ error in open loop.

I’ll try to have another video out tonight or early tomorrow

For me, neither of those links are working.

Thank you for that. I corrected them and checked. They are working now.

​@@TitanTunedthank you for your help

为什么使用后我无法记录任何数据？

@@晶黄-d1o I apologize, but is there anyway you could put that into Google translate , I can’t get it to translate on my side.

@@TitanTuned They said "Why can't I record any data after use?" and I'm assuming it's because a lot of people don't know you can't view live data if you have any time based filtering. You need to save, close, and reopen your log file for it to populate. This is of course assuming you are logging the correct channels to begin with.

@@dobermanracing谢谢！

To answer 1. The vve graph is set up the same as you normally would P ratio or map divided by baro for row axis Engine rpm for column axis 2. Initially I tried to do that but “TH-cam does not allow brackets in the description” so I couldn’t do that. You can still take a screen shot of that and then copy the text in screen shot you can select the Text and copy /paste it into a text document. 3. You will still need to drive . But you won’t have to drive any where close to what you would with out the tool. When using the tool you will start to see that the corrections slow down. At that point it’s a good idea to do another drive log. Think of it this way , every time you use the tool to paste into the vve table. That is a drive log that you didnt have to do. I hope this helps if you have any questions please don’t hesitate to ask.

I will post a Google drive link with all the filters.

I use the smoothing option as opposed to the calc coefficient option for no other reason then it is a little bit of a time saver. I completely agree with your statement about HPT suggesting smoothing before calculating, however your VVE assistant tool acts as a great buffer to allow smoothing how I do in the video. 1. You can immediately see how lean or rich cells are. 2. Doing it the way in the video keeps those coefficient mountains that randomly pop up on the vve table when trying to dial it in pretty much to a minimum. Thank you for the tool it is amazing!
