Tactrix 3-ports BCS install on Evo5

Hi guys,

are there are any differences between installing Tactrix 3-ports solenoid and GM 3-ports solenoid on Evo5 JDM?

I have installed one (like in this post http://www.lancerforums.com/forums/5928385-post50.html) and still can't get it work.. Here is my situation:

If I connect it without resistor it looks like fine, the car is over-boosting like it should, but when I make changes in ROM (as described here http://forums.evolutionm.net/4426597-post4.html or here http://evoecu.logic.net/wiki/How_to_Tune_an_Evo_TB_Alternate), there are no changes in boost after reflash, it's still over-boosting for about 1.6bar =\

If I connect the solenoid using resistor, the car boost for about 0.6bar and there are also no changes after reflashing. Looks like Tactrix BCS doesn't work at all with resistor (I have the same effect if I disconnect power from it at all). Resistance of stock BCS on this Evo5 is about 72 ohms, the Tactrix BCS is 24 ohms, so I decided to use 47 ohms resistor on the ground wire.

What I'm doing wrong? Any help will very appreciated.

what rom and which xml are you using, iirc some of the boost control tables had the wrong adresses in the earlier def file
