I think i know!!

 

Ive got a HKS one on at the moment, think its playing up. Ive had a problem since i got the car and £680 of inspection work from Chris Wilson says its not mechanical. So i reckon its the FCD,

 

Im going to post a video up in the next few days about this displaying my speedo and rev counter. See if anyone can tell whats going on!!

I think the main two problems with it are that the fuel cut is completely eliminated rather than raised as supRo said, and that the way it tricks the car stops the second turbo pre-spooling properly. I can't find the article about this at the moment though!

Thanks mate, just read that. I think i may have found what could be causing an issue with my car that really bugs me!

 

It mentions quite a few times in that doc that the FCD plays a part in controlling idle speed, and that the HKS device has been known to cause erratic idling.

 

Mine is an auto and the idle speed normally sits around 200 rpm! normally at the first small line just above the first big line. Its so agravating as you can pull up to a junction and it can make the steering wheel vibrate a bit, it never feels like its going to cut out but i've never thought it was right.

 

I've mentioned it to people and asked if i should clean the idle control valve or something, to which they said probably not

 

Could my HKS unit really be causing this? If so, how much is the Thor unit and where is the best place to get one please?
