Mitchell Middleton Posted April 9, 2014 Report Share Posted April 9, 2014 Gday guys on cold start my s15 200sx with link g4 for some reason makes my vct solenoid click in and out until the engine warms up. My tuner said he raised when the vct comes on above the cold start idle but it still happens a bit. ( although alot better ). Could there be another reason? Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted April 10, 2014 Report Share Posted April 10, 2014 In theory the VCT should not operate until around 2500rpm. If you had a log from the ECU while the solenoid is activating that would tell us a lot. Quote Link to comment Share on other sites More sharing options...
Mitchell Middleton Posted April 22, 2014 Author Report Share Posted April 22, 2014 OK I will try and get a log of the solenoid. I downloaded the PCLINK. It is the latest and last version for the G4. My tuner would have used the version one previous to this. Is this an issue? The website sais that changes may result if different firmware versions are used. Not sure if this relates to me. What do I do then once connected to the ecu? Thanks. Mitch. Quote Link to comment Share on other sites More sharing options...
Simon Posted April 23, 2014 Report Share Posted April 23, 2014 No problem to use the later PC link it will still connect to older firmware version ok. If you however run a firmware update to the ECU then you will need to check all settings. Quote Link to comment Share on other sites More sharing options...
