Just after the computer codes and how to read them off the computer, caus my R34 wont run at all now, it had stalled a couple of times before now. It blows a heap of black smoke out the back, i think it keeps flooding itself. The only mods on it are a HKS F-CON PRO V piggy back computer for fuel and ignition timing, HKS EVC 3 boost controller,pod filter,HKS FMIC, 3inch exhuast and HKS SSQV as far as i know. It is an auto tiptronic.
Any help would be great
