VT $A5 V6 Definition Info

[Doctor Bob]

i have had similar issues with TP5, am sticking with v4 as i know it works
keeping all my xdfs in V4 format

If you build the definition from scratch with V5 I don't think you will see this issue. Mark is still hard at it, so I guess some time in the future you will see an update. Maybe some of these issues might be fixed. Still like the extra features in V5 though.

I've been looking through the different variants trying to get a grasp on the changes, here is a quick update:
Variants F, G, H, J, K appear to have all the Transmission calibration data in the same area up to around the $3790 area.
The Engine data appears to be the same for Variants F, G & H (at least for what is in the xdf at the moment) but for J & K it is around the same area as in the variant F xdf but is offset by about 1-15bytes in either direction depending on the variant and area you are looking at.
Hope this makes some sense.

OK, I've updated the variant F xdf and also created one for Variant K, refer to first post in this thread.
I've also added an excel file that is my first take on how the PE AFR and Spark tables work.
It is a guide only, especially for PE, as there seems to be other things going on as well, but it ties in fairly well with what I've been datalogging, as well as others.
If anybody has any other information it would be appreciated, either post here or send me an email or PM.

Thanks,

nice work on the spreadsheet, i've been looking at vs v6 xdf trying to work out the fueling and spark stuff and i was doing lots of

this helps!

[yoda69]

I'm still not sure how accurate it is, but I hope I'm on the right track.
I spent ages stuffing around with the spreadsheet, hopefully everything works OK now, if not let me know and I'll try and fix it up.
Initially I tried making separate tables for different points, didn't take me long to work out that there were hundreds of different table combinations, hence where this ended up.
If anybody had any ideas on how to improve it let me know also.

well the numbers in your table are similar to what i've seen in some of my logs! really rich at high rpms!

[yoda69]

The data in the tables is from a S/C bin, and yes, they definitely run rich.
The NA bins don't run this rich from what I've seen.

well i was seeing 1000mv on my o2 sensors in some of the logs, thats alot richer than the 800's im used to seeing

Looking through these XDF's the open loop air fuel ratio only goes to 4800RPM. Is there anywhere I can get a XDF that goes to 6400RPM like the spark advance or atleast 6000RPM? I am using tunerpro V4 and VT V6 V1.4 $A5F.xdf but looked through a few others and they all don't have the extension that goes from 4800 to 6400 like the spark does.
