TunerPro V5 Calc'd VE

Can someone tell me where this value comes from in the data stream? I see the equation is X * .195313 , but what is X ? Also, what is this supposed to represent? the value in the VE table at that time?

by the way this is for saujp V4a

Re: TunerPro V5 Calc'd VE

if it's like A1, then it's just the result from the 3D VE lookup(A1 adds the 2D table as well, but 8D doesn't have that)

Re: TunerPro V5 Calc'd VE

Dude if you ever find a job I don't think you'll be around as much helping out all the dumb asses. I know you are an expert on these definitions but what you just layed on me went zoom.
I've never looked at a V6 bin but I'll take your word they might be the same. What I'm not getting is where is this coming from? I've seen linked outputs in the equation, constants, and native arguments. Calc'd VE uses a native argument that comes from 0xffffff . WTF?
I just hate not understanding something. It varies from about 32 to 41 but in no way is close to the VE table. Is it supposed to be the same from the VE table? If you can make me understand this I'll send you a 6 pack of your choice. Where's the Tylenol?

Re: TunerPro V5 Calc'd VE

That was just something I was playing with when I did the last revision.
I swapped out the first 2 bytes (PRom ID) for a calculated VE value that was being used in memory. Not in the stock $8D datastream.

The conversion number in the ADS is 100/512 = 0.195313 but I'm thinking the value should be 100/256 instead. X * 0.392168 +0

This is because the one byte had the whole number and the other has a fractional remainder. I thought this was a 16 bit whole number but it is not.

That was it JP, the numbers jive perfectly now. That's twice in a week I caught you. I feel like the proof reader on one of Einsteins' published theories.

just a note..my math shows 100/256 = .390625
is your calculator calibrated right?

Re: TunerPro V5 Calc'd VE

I aints perfect fur sure.

100/255 because zero doesn't count as a value.
Sorry, did it again.
