any XDF info for this Kal bin?

[Doctor Bob]

yeah delco can you send me an updated xdf pls, yeah the spark map is nice hey.lol
does it look like $1700 woth of tune to you??
it drives ok its a torque monster
454 cubes 4wd 4.5 diffs all locked 35" tyres hehehe
fun in the mud

Cheers for the kind thoughts guys

closed throttle ve at 0x0629 1 row 17 colomns wide

[delcowizzid]

this may help too LOL the colomns are 400 600 800 1000 1200 1400 1600 1800 2000 2200 2400 2800 3200 3600 4000 4400 4800 the values in the cells are VE

think the equation is X/2.56

think the equation is X/2.56

Slightly OT, but I've wondered about calcs in a few XDFs

Some seem to use 2.55 some 2.56 for conversion.

My thought was that 255 is the correct value, since the maximum 2digit Hex value xFF is equal to 255.
So you would never be able to achieve 100% with the equation X/2.56

255 = 99.61% 255 = 100%
2.56 2.55

Thoughts anyone?
Am I missing somethign simple?

its 256... "0" is the first digit

[vn5000]

You beat me to it Dr Bob.
Including zero there is 256 values.

[darcy]

its 256... "0" is the first digit

I agree that there are 256 values.
I dont understand how we can divide by more that the max value to determine what percetentage of teh total is represented?
If the values were only 00, and 01, then surely you wouldnt say X/2? It wold be x/1, giving 0% or 100% of the maximum?


Am I still missing somethign? Does x00 not represent 0%?

Not trying to be a pain here, just want it to be straight in my head.

cheers

I agree there are 256 possible values for an 8 bit byte, but to get a percentage where you can get 0-100% then it should be X/2.55 or X+1/2.56 depending on the range. I dont think X+1/2.56 would be used much (if at all) though.

Also interesting, I noticed some time ago that with kal sp3 (before OSE12P existed) many of the gauge screen percentages (such as TPS) wont go past 96.4%, which I presume are the same off by one bugs!

Bit of a brain teaser isnt it .
I think Antus must be right with x/2.55 if you used (x+1)/2.56 and x was 0 ,then you would not get 0% .x/2.55 is the only equation that satisfies the values x= 0 and x=255.
