Mine is here tomorrow and being installed next Monday. Thanks Steve

Screen

The EVC has utilised and LCD display since its 2nd version but until now they have all been monochrome. The 4th and 5th generations had bar graphs displays and many other types of data but they were all set in predetermined locations and patterns making it difficult to display text and images.

All this changes on the NEW EVC with the introduction of TFT Colour LCD. 320px x 240px screen give a completely free full colour canvas to work on. This is the result of the development of technology in LCD panel displays and shows how technology has moved on in the 6 years since the release of the last EVC.

The TFT screen surely does look great, but the main objective of this adopting this technology was not just to look good but to be able to display the main screen and 10 other pages which vary greatly in appearance. Previously it was only possible to display basic letters and numbers but now, complex characters and graphs can all be displayed.
The new EVC does have some new functions but many are carried over from previous versions. Older EVCs have also carried many advanced features but it has been difficult to display these functions clearly.
For this reason, the many functions of the EVC were accessible to experienced tuners but not so easy for common users to make full use of them. However, the new EVC can display the many functions over 12 pages. This should allow all users to fully understand and make use of the many features making the transition from a "tuners tool" into an "EVC which can be enjoyed by all". The new EVC brings back the appeal of tuning to the users and the new TFT colour display is at the centre making this possible.

Valve Unit/CPU

A boost controller restricts the pressure applied to the actuator in order to maintain control of the boost pressure and therefore must have a valve unit. The valve unit can be considered the "heart" of the boost controller. Most boost controllers on the market use a solenoid valve which repeatedly opens and closes the valve. However HKS EVC uses a stepping motor instead. By having a tapered shaft inside the orifice and combined with the stepping motor, it is possible to have not just open and closed but also all the precise control in between. This allows for small adjustments and precise boost control.

The new EVC has a new design valve unit. The first difference is the case material. Previous versions used aluminium whereas the new version is made from resin. This has allowed for much more accurate production, increased durability and heat resistance.

The valve unit circuit board has also been completely redesigned allowing 3x faster response times. A boost controller measures intake manifold pressure and a computer determines the necessary action to take in order to reach the desired boost pressure. This signal is then sent back to the valve unit. The time required to calculate and execute this process is now 3 times quicker than before. This has allowed target boost to be reached much more efficiently.

The basis of boost controller performance lies in its ability to control boost accurately and with stability. This has been improved for the new EVC.

 

Looks nice. $?

 

you will be very happy with it

 

Looks nice. Where does it sense boost, at the head unit or the control valve?

Thanks,

Tom

 

700Ish

 

Hmmm...

 

It's only money. JUST DO IT!!

 

for that money i'd be using an AMS1000

 

can you explain why? I thought those only work on external wastegates (ie: not your alphas)

 

looks like a nice unit - pricey tho...

 

I might have a brand new EVC VI (latest version released in the US, black and white screen) available.
