Not sure how to to setup the speedo after my t56 swap. If someone could tell me how to do it i'd appreciate it. Im running 4.10 gears and 27" tall tires. Oh im using hptuners too. Thanks alot.

 

VSS pulses per rev needs to be 17 and you have to do the calculations on the revs per mile with your gear ratio and tire diameter.
In case you need help, 5280' are in a mile, diameter of tire x 3.15967 (pi) = circumference

 

here you go adam. copy this table.. i did all the work for ya

 

Well kiss my ***.

I would have done that if I could ever figure out how to copy and host a screen shot.

 

Awesome, thanks alot!!

 

Well i copied that table over but as soon as i hit save the tire size went to error. The calculated tire was right so i loaded it up and tried it anyway but the speedo isn't anywhere near right. Any idea why it would do this?

 

Ok, I did some math. I found your tire size in your sig to be 27" diameter exactly.

Change the General VSS Pulses per Mile to 52064.227

And the trans rev per mile to
3062.601

Let us know if that works.

 

you need to print screen, go into paint and paste it. then save as....then photobucket. on my laptop i have to hold a button that has blue on it that says FN on it along with pushingthe printscreen button

 

anything different in those settings will cause it to be off. mine was within 1mph

 

I've got it torn apart right now to fix an oil leak, once its running again i'll try that and let you know. Thanks.
