Rolly95 Posted September 22, 2022 Report Share Posted September 22, 2022 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?

Adamw Posted September 23, 2022 Report Share Posted September 23, 2022 Sounds like you havent set ignition timing (trigger offset). Try it around -85 as a starting point, many RB's seem to come out around there. Quote Link to comment Share on other sites More sharing options...
