The shift points and in the ecm constants there is a Vss Diagnostic Enable Min RPM table that you need to raise to a point above your stalls rating. This number usally needs to be above the highest flash point of the stall.

ok, also since i havent tuned it for the stall would it make it seem like the stall is smaller. i mean mine was supposed to be a 4k from a friend that said it was a 4k, he swears that thats what his dad bought and told him. it seems like it would be a 3000 maybe 3500 but not sure since this has been my first stall i ever put in.

It is hard to determine the true stall if you are not use to one or datalogging. If you are trying to torque it up and the tires are breaking loss that is normal. You will over power the tire before reaching the true stall speed. The amount of power and the rearend gear have an effect on stall rpm to. But the tune will not effect it.

i was doing some changes in shift points today and went to change the vss diagnostic enable min rpm but i didnt see table for it? i am using the bin file i pulled off the computer when it was tuned before i got the car. then i checked out the bin file TC gave me and the tables are alot diffrent how come?
