SMC
It does govern boost, but not through a handset
It took me about 6 months to decide what ecu I wanted, I got the chance to drive/ or drive in several cars with a variety of ecu,s bar any Motec which is about the only thing I'd consider replacing the Autronic with but the $ was the deterent at the time.
Drive before you buy bud, sift through the propoganda, remember make sure theres a number of experienced tuners for that ecu in Perth.
That MetallicBlueR33 guy In SAU has a SM2 minded R33 take a spin in that for drivablity, Im sure SST can slap you into a ride in a wolf r33..... and the RB25det with the link....... Be nice to see the new Haltech too. Focus on the way it drives
Good luck guys
