Hi All,

I am new to this forum and recently purchased a 1997 R33 GTR Vspec from Japan.

Its not arrived down under as yet and probably be a few weeks/months away from landing here.

The reason I write is that I have no clue of what this HKS unit installed in the glove box is - does anyone have a clue and what it does?

I know it'll probably have to come off during compliance - but I am still interested on what it does.

It looks pretty serious! Sorry for the nube question and I'll be grateful for any advise.

Thanks!

it's a HKS EVC

it will have to come off unforunately... and they're only worth about $20 these days...

...if you want i'll be happy to take it off your hands for $20! but yeah... you can't have it.

...oh and i'll want all lines and valves etc too.

:)

............. okay FINE. $30 and that's my FINAL offer :P

nah just kidding. it's a HKS electronic valve controller, (EVC)

can't tell what model it is but it doesn't look old ... actually i think it's an EVC 4??? i beleive they're up to EVC 6 now???

basically

*BRRREEEATTTTHHHHHEEEEEeeee*

HKS' all-new EVC (Electronic Valve Controller) is the first boost controller to feature integrated CPUs in each component (Display Unit, Control Module, and Stepping Motor) for more precise control, quicker response and improved boost pressure stability. This race proven system is available in kPa and PSI measurement and features an easy-to-read LCD panel that can be positioned separately from the control module for driver convenience.

***RRP - $1299 :)

Thanks for that!

Apparently a new one of this is worth over $750 on the HKS website! :D

Not sure why the owner has installed it the way he has - surely it could have been installed elsewhere or in some other way.

the gauges look like A/F and exhaust temp

and yes the New ones are prob worth that retail but that one would be worth alot less it is just a boost controller i you dont have to view them 24 7 and hidden away is a nice for the un suspecting

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
