Cold Start - Boost Issue

Recommended Posts

Hi all,

 

A couple of times recently from cold start the boost seems to be non existent (despite the whine) and then 'snap on' all of a sudden in 1st and 2nd.

 

This is all at under 3k rpm and only happens when I leave for work and am trying not to wake all the neighbours. Is this normal?

 

Rest of the time it is fine.

 

 

Setup: boost controller @1.1bar, cat back trust exhaust, FMIC.

 

 

Thanks in advance :)

The VVti throttle body can give strange issues. It might be worth trying the reset below as it's so easy and has cleared up others issues before.

 

 

•Try reset the ETCS-i system – Turn the key to the “ON” position but don’t turn over the car, put your foot completely down on the throttle “Gas” pedal for 30 seconds, you should hear a beeping/humming sound while the ETCS-i system resets, turn the ignition to “Off”. Now turn the car back over and re-test to see if you have any symptoms.

I would print/save this personally if I had a VVTi :)
