Quick easy question

You can use the A9l or A9p. on a T5 they are both good. The A9p is the Auto one, and they claim it has a faster timing advance ramp to it. I used this one because i got a better deal on it.
 
Oh I forgot...You can use a auto or 5 speed eec with a T5 car, but you can not use the manual trans eec with a auto if i remember right.
