i think too expensive la.. might as well go for standalone... much better reading of everything... and more tunable making it possible to use optimum of power...
got some ppl at drift.com selling standalone ecu at 1k.....and piggyback at around 1k also....u should go check if u want...
but it's for 16v engine if i'm not mistaken....
he said 20v ecu much easier to find....
if u've got that performance ecu,
they say u wouldn't have speed cut, ignition cut and many other extras..
i'm not pretty sure since i'm noob....only hear ppl say...
