We've just fitted the EVC 4, and have a few problems....

1. If I set the High Boost to say 1.1bar, the boost reading goes upto 1.2-1.3, but on the dyno the boost is holding spot on.

2. Had a mate look at the instructions, and he thinks the LOW boost setting is when the controller starts to open the wastegate for spooling & the HIGH boost setting is the limit of boost. I thought he was crazy, because as I understand it, the LOW boost is for lazy driving & the HIGH boost is for everyday driving. But after some testing, I think he is correct, maybe someone can test it themselves? When I set my LOW Boost to eg: .5 and HIGH to 1.1 the boost comes on smooth and early, if I set my LOW boost equal to my HIGH boost, the boost is much more agressive and comes on later.

I'm running HKS Silver Actuators which I believe are .9 ~ 1bar, If I'm setting my EBC LOW Setting below this figure, is it useless having these actuators?

from the experience i have with mine

i used to have my low boost set at .5 bar and high of .75 bar and it seemed correct according to the boost guage

thats how it worked for me so thats my understanding of it

Your mate is incorrect.

EVC has two boost settings, hi and low. Their adjustments do not have any effect on how the boost comes on and judging it by the seat of the pants can be misleading.

If you have 1 bar actuators, you can't set the low boost below that. Simply, the boost controller can not hold boost at 0.5 bar, if your wastegates don't open tilll 1 bar.

So, set your low boost at minimum 1 bar and high boost to whatever the car has been tuned to on pump fuel. If it isn't holding boost correctly it can be fined tuned with the offset feature. FWIW, mine is set at 1.40 bar and never gets touched, would you set your rev-limiter at 6000 rpm...?

The best way to monitor your boost levels is on the dyno, as the peak hold values shown on the hand controller doesn't mean much. Saying that it's common for an EBC to behave differently on the road compared to the dyno, if a high ramp rate have been used.

Just thought I update this thread...

My problem is all fixed now.. turned out the evc needed a RESET & LEARNING MODE run. I basiclly followed the instructions as detailed in the EVC setup manual. The boost now holds/reads perfectly, and the OFFSET mode setting is spot on 100 where it should be.

After the RESET & LEARNING MODE runs, I also turned off the AUTO ADJUST setting as specified in the manual which it recommends to do, simply by: Turn the Ignition to ON, holding the MOD button, flick the SW-PO switch > wait for the beep (still holding te MOD button) then return it SW-PO to it's original position and you should hear another beep.

So if anyone is having issue with boost readings going over the set boost levels, and you cannot adjust your OFFSET any more (eg: 50 or 150 - like me) just do the above or refer to the manual.

Does anyone have an evc 4 pdf manual ???? or know where to get one ...

i have an evc 4 sitting in a box, waiting to be fitted as soon as I move into my new abode, and get to unpack all the boxes ..

and i'll be buggered if I can remember how to install it. had it in my mr2 turbo first, then pulsar gti-r, now the skyline ... rar

also ,i have not taken delivery of the car yet ...

i managed to get a grade 3.5 gtst s2, in solid red ... a rare colour as far as I can tell ...

anyway, if anyone does have a manual, can you forward it to :

[email protected]

Thanks very much ...

When you first install the evc you have to let it learn your actuator. go for a drive, put it in 3rd and from 2000rpm floor it to redline. Then tune it from there. I have the ricey EVC5 and its a really good controller imho.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
