HKS EVC 4 Problems, Help! - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

I have an HKS EVC 4 in my R33 GTR.

The car has been setup to run 1.4 bar by Abbey Motorsport.

It's currently only making a maximum of 1.3 bar sometimes 1.2 bar it depends if I boost in 5th or not.

Here are 2 pics I have taken of my EVC Screen.

This first pic shows setting A. Its a low power setting and reads 100kpa when full boost is reached. Please note the "60" in big numbers. This only appears for a few seconds when the "A" setting is selected. What does this mean?

Here is a pic off setting "B". This is the high power setting where it should make 1.4 bar.
Again notice that this pic shows "92" in big numbers, What does that mean and why is it different to setting "A".
Also note - i assume that the figure "145" which appears above the setting A/B indicator is the target boost pressure.? If not what is it?

Finally why does my car not make its set boost pressure any more. The turbos are new and only been on the car since Oct last year. they are 2860-5's

Help Help Help..!!

anyone... I have started another thread on the standard BOV's as a potential culprit. Where are they located on a GTR.. I'm buggered if I can see them anywhere... but they must be somewhere as I can here them opening. LOL.

Again, is the "145" on the top left of the EVC screen the target boost pressure.??

Standard dump valves have had it. (will post a pic of the crack)

The car now makes 1.4bar without a problem and holds 1.3

Previously made 1.3 bar and held 1.2

Simles all round as my first theory was correct.!!
