Yes...I will probably drop this one this week and wipe my hands and call it good. There are a few features I would like to try to add in to prevent those saddle shapes for missing data (just so this is a little more usable to those not as proficient with VVE stuff). Then the real work will begin on version 2.0!Originally Posted by cpd004

I was watching the VVE video and it shows that the boundaries need set up. I have the speed density 2bar OS patch installed. Would I still be able to use the VVE tool?
the proper VE table is easy just get the error data as normal and adjust it, the VE dosnt have to calculate to anything alse it just stays as its adjusted cell by cell
Ah ok. So, no need to use the tool. Just have to make sure to plot against dynamic instead of the fuel trims. Thank you!
even easier its just wideband or trims error against the VE map/rpm table and ur done
This tool is overkill for a standard VE table. However, there is one advantage in that you can take many logs and average them together into one massive histogram to get a much better long term average.

With that said; the only other thing I think I would need to do, is use Dynamic instead of the LTFT & STFT, correct? And that goes for MAF tuning as well?
With or without a filter and how many cell hits do you recommend?

Yes, and just be aware that in the HPT Scanner MAF maxes out at 512g/s and VVE maxes out at 655 g/s. So if you hit those caps the DynAir method, its not going to work.

Could you explain a little more on where in the tune file the maxes are for maf and map and how do we log that in the scanner? Thanks Cringer

The issue is not in the the tune or in the editor.
The issue is an inherent defect in the HPT scanner (or maybe a limit of the CANBus or ECM itself, but probably HPT, IDK). Either way, the scanner is unable to report airflows above these numbers. And since these numbers are absolutely critical to the Dynamic Air formula, it renders this method helpless above these caps. Check this post's attachment... you can see the MAF and VVE values climb and then they flat line when they hit the built in limit in the scanner.

Ok, I see what your talking about. Thanks again Cringer

I've always heard of those max limits. What happens if you simply change the limit in the scanner? Right click charts, select MAF then raise the limit? Seemed to work for me but not sure if there are drawbacks to that.
im old school ill go thru the log with no filters/cell hits and just grab the parts i need and add to the VE and then build it all out to the previous cells so its all smooth from there
Thank you sir.

Won't have any effect...they will still max out at both of those limits no matter what you put in.
As i started this process i had the virtual flex on. Felt better at the 14.3 afr, set to the factory 14.7 with Flex fuel off. Now performance seems to have gone away as i use these math's. Pedal response has gotten worse. Should i have it in force MAF mode? normal driving mode? My vve has gone pretty flat and one peaky area. LTFT lean 14-16% at idle. STFT don't indicate a vac leak issue. Also currently have DFCO off when i was following GRG's method. Comparing to my afr on bank 1 i'm lean.
What am i doing wrong?

I am not surprised with your drivability results.
I see three major issues:
1) The first issue is the most common issue I see, you are not logging the Fuel Trim Cell PID in your channel list, which is required for the filters, at least as how I use the filters.
2) You have a variable camshaft enabled and you are not logging the camshaft angle. You will need to log this and then add the filter for the cam angle = 0 to tune in "basic" mode (to use the VVE Assistant program I wrote). Then once that is set up you can move to advanced mode to work on when the cam is not parked.
3) Your high octane spark table...needs work
Additionally, I removed the large spike anomaly from your VVE in the idle area so I could get a read on the rest of the VVE. It is NOT smooth at all (see screenshot). Sounds like your VVE is a work in progress, but you goal is to smooth it out. Have you watched the VVE videos and used my tool (check my sig, you will need to watch both videos in order). No need to disable MAF, these formulas work in hybrid mode to tune both air flow models.
Keep at it, and you will get where you need to be!
Edit: I would recommend never using virtual flex fuel, especially if any engine modifications have been made. It is sketchy at best on a OEM fitted vehicle.

i will add that into the channel list for next log, it is indeed a work in progress, taken me a few months and as far as ive gotten. I thought my vvt was disabled along with the dod?
