Got a link g4x plug in for my r34 with a brand new wiring specialties engine harness to suit ecu, pretty new to the aftermarket ecu/tuning thing, so some helps troubleshooting would be great. -all pre start checks/calibration’s done on pc link AFAIK. tried cranking over, engine seems to choke and hesitate, if I unplug the CAS or Ignition harness the engine cranks strong & smooth, managed to turn over the engine once (albeit with a large vac leak) any help on where to look ecu wise?

Yeah I did read about that in another thread, gave it a shot but to no success Although the battery may not have been 12v charged. I’ll give it another go with another battery

Update; I’ve tried re-installing the pc link software and drivers a couple times, unsuccessful. gone through device manager and located the usb drivers, plugged/unplugged to make sure the computer knows what I’m connecting to. still no luck. error I’m receiving is - 1005 and occasionally the notification window telling me the ecu is in boot mode Again, any help would be appreciated.

Recently installed a new ngttx plugin ecu on my r34, along with a brand new wiring specialties harness & link wideband setup installed pc link to my laptop, updated drivers. igniton on to power up the ecu, blue light appears, connect ecu to my laptop, but pc link cannot find the device, best ive gotten is a notification that im stuck in boot mode. re-installed pc link, re-updated drivers, still no luck. on a side note, with igntion on fuel pump continues to prime, has been wired to recieve 12v. could that be an ecu issue, since the ecu isnt on its not able to switch the relay?. any adivce on where i can go from here?
