How to Datalog an automatic

[bigemrich]

I tried to search, but found nothing. I was wondering how to run a datalog for an automatic. In a manual I heard you are supposed to do a third gear pull (I think), but what does one do with an automatic? Thanks alot for any help and links would be greatly appreciated.

Hit the gas WOT and go.

Turn O/D off and take it up to about a 50MPH cruise, then floor it. It shouldn't kick down into 2nd if you're going fast enough when you hit it. BTW, this is the same method to use on the dyno.

you could also just leave it in D2. it'll shift down from it, but it won't shift up to 3rd. if you need better resolution (i.e. you need it to take longer) just give even pressure on the brakes to increase the load so it takes longer to accelerate. might take some practice..
