Я также ипался как и все те у кого есть данная проблема , у меня был р72 мозг и соленойд жил своей жизнью то передует то недодует то ваще хуй пайми чо делает, а в логах все красиво pwm работает как надо, щас у мя р28 мозг и та же история, я даже летом гейт поменял с 38 на 44, но нихуахуа...
И вот тут недавно задумал поменять свой трехпортовый мак на 4ех портовый

и продаван мне местный рассказал про УСИЛИТЕЛЬ
http://vittuned.com/tuning-products/vit ... oster.html
Вначало было я подумал рекламко заманухо - но он такие не продавал, а себе на аккорде сам там купил и поставил и говорит помогло аццки как...
Как я понял сигнал с мозгов в большинстве случаев до соленойда доходит слабый и силы не хватает нормально быстро открывать закрывать соленойд и все такое, а этот усилитель как раз таки решает эту проблему и бла бла бла, я подумал и решил повестись тоже.. и купил сие чудо, вот жду когда приедет, поставлю вместе с 4 портовым соленойдом и отпишусь, помогло или наебали

If you have a forced induction vehicle tuned with a Hondata FlashPro, Hondata KPro, Hondata S300, Neptune or KTuner, this product is a must have for you.
The boost control on these ECU's uses an EGR or PCS PWM circuit which was never designed to drive a high load solenoid like your boost control solenoid, which amounts to your boost solenoid being under utilized. You get scenarios such as:
Limited area of control of the solenoid (for example, 25% to 65%, 30% to 80%), where as you should have FULL control of the operable area of the solenoid (10% to 90% or higher).
Unstable boost control (the solenoid will skip a beat as the circuit simply cannot provide enough current to run it smoothly) causing random boost up and down in the middle of a pull.
Unreliable boost control - you'll see huge swings in boost with no change in duty cycle from day to day or even pull to pull in some extreme cases.
Unpredictable boost control -- a simple 1% duty cycle change in boost control can cause huge changes in target boost, making it difficult to dial in the boost control.
Random boost cuts with no changes to the boost control duty cycles (overboost situations).
We have created this solution that uses your EXISTING boost solenoid (or you can order our 4 port boost solenoid if do no have one yet) and wiring to give you complete and predictable control of your setup. Not only do you now have control over the full range of your boost solenoid (10% to 90%+), but testing on personal vehicles and independent vehicles has shown that with the VitTuned PWM Booster:
You get much more predictable boost control - no more huge increases in boost from minor duty cycle changes (like 1% increasing boost 5psi...).
You get more predictable boost day to day -- we have seen only minor fluctuations in day to day boost curves, 1psi or so. Very acceptable for the open loop boost control system being used in those ECU's, much better than the 3-5psi swings seen otherwise.
Quicker spool -- with better control of the solenoid we have seen much more rapid onset of boost, which amounted to as much a 40-60tq gains in the mid range on some vehicles.
Those random boost cuts? This can make it a thing of the past for you.
Install is very simple -- just 4 wires: power, ground and the signal from the ECU. The two wires from the boost solenoid go right onto the screw terminals on the PWM Booster.
