Ummmm i am not to sure about this?????
i have a 2008 Subaru GTL stock ECM fromwhat i was told. motor heavily modified would like to write to it with HPT because i already have it hahaha but all i am hearing is bad things with HPT and Subaru's mostly bricking the ECM. the car had cobb but i unmarried it just to find out someone used romrider before the cobb. i have checked another GTL Subaru's different maps they have. i have contacted support about missing tables and also how to get the HPT features they just said they would get back to me. the only difference between my 08 GT Legacy ECM and the STI ECM is the AVCS exhaust. so i dont see why i cant use HPT. if someone can give me some advice that would be awesome
