Adamw Posted October 28, 2020 Report Share Posted October 28, 2020 On the early revisions of the G4X plug-in ecu the ignition driver gives a short pulse during boot-up, which has been found to be enough to cause a single weak spark at power up with some ignition systems. For some reason it is mostly WRX's that have reported this issue. The hardware has since been updated to solve this. If you contact [email protected] with your serial number and location they will advise the process of getting it replaced with the new revision ecu.
