Hey All,
I've been looking at a masterfully made $51E XDF & looking at different cal file's & it seems to be pretty close with even a,b,c & d in the $51 what are the differences in the offsets?
I have a moded $51D file that I wanted to try & make manual & just wanted to set up as manual, so flag as manual & VSS!
I couldn't seem to find the VSS flag, but there was a flag made for getrag manual that would be around where the VSS flag is I think?
Thanks VX L67 getrag

Re: VS XDF With Different Version's?
i've only really played with $51E hense the xdf
but it will be somewhere in the others there is an offset different like one more or one less item, and from that point on everything will be off by one .... but then if theres a second one further down the file then that will put everything after that point off by 2 or 3 ... so the long and the short of it is really if you want to define something thats at the wrong offset, just try changing the xdf item to a few offsets before and after its $51E setting and see if your tables look right
its like the VS V6 and VS V6 S/C start out the same, but as the file goes on theres more and more stuff for the blower in there which slowly offsets it more and theres something like 30-40 hex numbers between them when it gets towards the end.

No matter what the question is, the answer is always more horsepower!
