The built in boost cut control is useful, as a boost controller though it is quite basic according to the spec list. Worth spending a bit more to get an EBC with a gain function to control how the wastegate opens, this can make a significant difference to how quickly the turbos spool up.

 

There's this HKS EVC 6 for sale in the classifieds section, these are one of the best EBC's available. http://www.mkivsupra.net/vbb/showthread.php?313463-HKS-EVC-6-Boost-Controller-(NEW)

The display is clear and bright , (dim available) can be set to various units , acts as a boost gauge , it is very accurate ( verses dyno plot) , the voltage fuel cut is to 0.00 voltage settings so highly accurate , although adjustment requires unplugging to access.

The case is very sturdy thick aluminium and is a durable unit , the rectangle shape needs more effort to mount than a circular one .

Turbo timer works but needs more wiring instal time . The solenoid appears durable and fast acting .

Has enough settings (6) in memory and gain adjustment simple .

All in all a good little unit despite the naff name

The voltage is say 3.54 not 3.5 it's accurate and adjustable to two decimal places , the adjustment is by a small screw adjuster in the back but you need to unscrew the rear plate to get to it - this means you have to unplug the connector at the rear to remove the plate to get a screwdriver in - thus the voltage adjustment must be the first adjustment - it's not an external or push button setting ,

At £200 they are cheap enough for the quality and ease of use and installation - it's also a voltmeter

So voltmeter, timer, FCD, boost gauge,boost controller, all in one - boost controller is 6 settings and scramble boost with variable time and % over boost , and warnings of over boost with lights or flashing display

Do you understand that each and every ECU fuel cut voltage can vary , do you understand that each and every map , sensor output versus boost can vary , do you understand that sensors can drift ?

Are 4.27 and 4.38 and 4. 21 and 4.33 volts the same , if YOUR fuel cut was 4.19 , which voltage setting would you prefer? No one knows YOUR fuel cut voltage on YOUR car , no matter how much you search the internet .

There are instructions included with the Gizmo , you follow these to set up the unit - it's that simple

Fit , adjust , test , adjust , test , adjust , test - until your car is set - you have the ability to adjust to 2 decimal places (I can't explain that any better) some FCD are only to 1 decimal place 4.3 , 4.4 ,4.5 etc

I have given you an overview of the unit based on the three I have used .
