I am currently deciding to purchase boost controller as my Link ECU does not seem to control boost effectively,overboost often.
For those using HKS evc or Blitz boost controller,would appreciate very much if you can provide some info regarding these boost controller,eg overboost or boost fluctuation problem encountered??
Thanks in advance.

Hi Chan,
You're best bet would probably be to speak to Jan Shim who lives in your area, he has used the HKS EVC and the Link. With the EVC the boost is consistent, it rises very smoothly, holds and then gently decreases at higher revs. I would imagine that this decrease in revs is due to the standard TD04 turbocharger running out of puff. There is a switch on the back of the evc which allows it to hold the preset boost no matter what so even if your turbocharger is worn it will work it harder to acheive the same boost, I leave this function turned off on mine. The HKS EVC is brilliant and arguably the best device on the market for controlling boost only beaten by the more complex EVC pro. I'm not sure how well the link works with external boost controllers, I popped the question a while ago and was told that it had to use the standard boost solenoid (replaced for the three port one though).

I ought to answer the question a little better really.
There is marginal overboost with the EVC if you say back off and reapply the throttle but this is in the region of 0.02bar at most which is minimal. The boost does not fluctuate. Before fitting the EVC the boost on my car used to fluctuate wildly and overboost, with the boost needle showing spikes and troughs everywhere. Boost is so much more controlled now.

Hi Nito,
Thanks for the info.Yes,I know Jan very well and in fact he too is facing overboost problem without HKS EVC.Our setup is Link with 3 port solenoid but we seems to find that the 3 port solenoid seems to cause the overboost problem and adjusting the Link to prevent overboost,we will get the too much lag without overboost.The problem I encountered at the moment with boost set at 1.2 bar is whenever I am on part throttle and then go for full throttle,the boost will shoot to 1.4 and sometimes 1.5 bar before decreasing to 1.2 bar.I wouldnt mind if the overboost is 1.3 bar but 1.5 bar!!
I am sure there are those running Link with external boost controller and would like to hear from them.
