Adamw Posted April 5, 2018 Report Share Posted April 5, 2018 I think you will have to discuss with the installer, I suspect they have done a piggy-back install and the OEM ecu is not happy because they have disconnected the Vtec solenoid from the original ECU. They can possibly fix it by fitting a "dummy" solenoid or resistor. Quote Link to comment Share on other sites More sharing options...
