VN V8 $DB 0x47A

[Dylan]

Hoping someone can help me. I use the old $DB code a bit for a few different reasons. I'm using an XDF downloaded from this site.
There's one table with a description of ????????
Memory location is 0x47A

Wondering if someone maybe able to help out with what it is? I'm more curious than anything else I've never needed it just always wondered.

A bin and XDF is attached

All help appreciated

most the factory tunes are an evolution. if you take, say, a $5D xdf and match the items before and after it, you might find that there is one named item in the middle, and that is it.

Thanks mate good idea. I had a look at a 5D xdf. And couldn't find anything Ill have a better look later. Is it possible to search an xdf by addres?

the actual values at 47A are almost a carbon copy of the 5D "F53: Initial Crank Base Pulse Width vs Coolant Temperature" table. thats what I reckon it is...
except DB already has a table labelled "FUL CRK BPW" with similar values, but not exactly the same. maybe one is first stage and the other is second stage?

one way to find out... take a big swing at the tables and log it starting up and see if crank BPW changes at 160 baud speeds you may have to have a few goes... I cannot imagine the reason for running old 160 baud code? care to share your "Different reasons"?

I have noticed DB only has one cranking fuel table, defined at least anyway. Im tipping the defined one is second stage.

I do a few re tunes or touch up's locally. There was a bloke doing tunes in my area (whole country really). I won't say his name but everyone here would of heard of him. He done some great work.
I've picked up a fair few re tunes or adjustments. And he loved using $DB. BDJH was his base for custom tunes.
I aways get a read of the old one first. Copy over to 12P and go from there.

First prize to Jayme, he got there first. 47A is Subsequent Crank Base Pulse Width vs Coolant Temperature -28 to 116 C

Thanks Kojab and everyone. I'll have a play with the XDF see if I can make it all work right.
I'll post up my effort later.

Thanks

Just having a look at this. Never modified an xdf before.
The values look more like a first stage cranking pulse width?
Kojab mentioned "subsequent" which I took as second stage?

Using those terms as that's what they're labelled as in 12P.
