Coltrain,
i refering to Sonics rids,if not mistaken his ride is V-tec
But my fren's is IDSL,different car.
Sonic,
As known, V-tec controller is gd to adjust the opening time and air flow for v-tec enjin. so,after all those modd relating to air/oil support. a v-tec controll ler will helps the performance.
for your case, notice that you are interested for open pod/extractor,mid bullet,tail muffler..to well perform these stuff,some ecu tunning is required.
correct me if im wrong,v-tec sifu here.
for 7-speed mode. yes,same case here. i think before red-zone than the gear will auto shirt up....that's a waste for this system...haha.
imagine,with 7 speed....all shift gear when red zone....listen the enjin screaming...shiok mar~!
