G'day Sydneykid
Actually I like the PFC, although they aren't really that popular with tuners in Perth (Lumpy excluded).
The reason that I will probably eventually go Autronic is mainly economics.
I expect to take my GTR (probably fairly soon) to the stage where I will max out the AFMs. When I change over terbs I will also want an EBC as well.
By the time you add 2 x Z32 AFMs and the boost control kit to the price of a 2nd hand PFC with H/C, you are getting near Autronic price.
Perth's summers played havoc with my S15 that was probably tuned too near the edge. With the PFC, it's not a simple matter of reverting to a more "conservative" hot weather map unless you go back to the default map, thereby losing your custom map created on the dyno.
I don't have the option of using a Datalogit as this is not (yet) available for the PFC Pro that I have.
