any XDF out there for the torquehead conversion

i have a 95 camaro z28 i used tuner pro rt and now i have the torquehead system with the 411 pcm i am having trouble with setting my speedo im using a 2002 xdf file from this site but the xdf names are different then the one i used on my 95 pcm im just trying to figure out how i can fix my speedo it is out by 20 km per hour when im doing a 100km per hour my speedo says 120 km per hour im not sure what to change in the xdf any help would be super as i am still learning how to do this stuff

oh ya i have 3;42 posi and 19in rear z06 vette wheels and a 4l60e trans
i guess what im asking is what scaler do i change to adjust my speedo

You can generate the correct values using BlueCat Trans Tool, a quick netsearch will provide a few download links across the net.

It's way easier than mucking around blindly.

What has you confused?

well i use tuner pro rt and i am using xdf for a 2002 which i found on here i have a 12212156 pcm but i cant figure out with the xdf what numbers i need to change

Try H0101 I think it is pulses per mile of VSS. It worked for me.

so mine says 57187 pulses per km and my speedo when im doing 100 km per hr says im doing 120 km per hr so its out by 20 km but i dont know how much to change the number by because when i use the xdf with my lt1 pcm tune it says its 159068 but i think thats cause the xdf doesnt work with the lt1 pcm tune and if i put that number in my speedo just goes all the way around as soon as i start moving
so im wondering if there is a formula to figure out howw many pulses i need to make it say to get the 20 km back if you know what i mean

If your speedo is 20% fast (120 indicated is actually 100 kph) them multiple by .8 (57187 X 0.8= 45749) So i'd try 45749 and trim it from there.

If you have trouble with editing the numbers you might need a different .xdf.

Is your speedo calibrated in MPH or KPH? Might be as simple as changing indicated speed.

thanks i will give that a try my brain just wasnt thinking it would be that easy sometimes i over think stuff
