HKS, Greddy or Thor FCD?

whats so bad about the hks one then?

 

i belive they modify the voltage from the ecu..so it fools it think its running less boost than it actually is..hence why it doesnt hit fuel cut...

 

So its running more boost..but fuelling for less, that isnt a good combo..

I see, and the Thor one does the same, but provides the appropriate amount of fuel? OR...

Can somebody confirm this? I have an HKS FCD and have not installed it yet.

The above is correct.

From what memory serves me from threads of old on here the Thor FCD will linearly provide move fuel where as the HKS device just caps and holds at the limit.

 

You may want to do a bit of searching in threads from 2005-2006 as it was discussed technically at some length.
