Help - Broken HKS EVC

[caminperth]

hey all,

was wondering if anyone knows of a service agent in perth who can look at my hks evc boost controller. the problem with it is that it won't hold a boost level - when set at 1.0 bar it fluctuates between 2 and 8 psi - measured on a dyno and on my boost guage.

i've replaced the controller with a bleed valve but spikes above 14 psi are not cool and neither is not having the cool readout on the hks..

any suggestions/flaming/ baggin/constructive ideas very welcome!

Have you shown it to Brett at all? he is pretty good with electrics and stuff.... maybe when you go away give him that to fix

[caminperth]

I think I might.. will just leave it with him and say - make it all work..

So how did the ITC go? Did it all work? You checked ur pm yet or are you just ignoring me?

[25GTT]

Nah I replied!

ITC hmmm ok ... well it works fine but started pinging on dyno run at Auto salon, so i was a bit upset but apparently it had happened to a few cars due to atmospheric pressure changes??

It does look pretty cool but i think i have to do another dyno tune with Brett to get it fine tuned for it... went there on Monday but was a bit busy... EVL R33 had apparently taken off his thumb in the door there!! and was in hospital!!! hope he is ok... his midnight purple r33 gtr is looking Sweeeeeet!! droolworthy!!

[caminperth]

Doh - so you did..

Not suprised you were upset. Wierd that it happened to a few cars. One would've thought that increased atmospheric pressure would mean more airflow - so maybe higher boost levels? That may have done it if you were running right on the wire at atmospheric? Maybe they should hold the dyno shootout outside next time?

Bugger for EVL R33 - hope he's ok. His car was lookin real nice..

Its called knife edge tuning, Tuning a car till it pings then backing it back, its pretty stupid but most will do it for that last kw, Any change in conditions and your car will start pinging, should tune a little more safely.

[caminperth]

RB20 - I can imagine people would do that for competitions, such as Autosalon.

Can I ask again tho - I really really really need some advice on where to get this thing fixed...

Have a talk to XSpeed as they deal with HKS and might be able to help you out, also check all your piping (intercooler)and tubing Vacuum etc) to the EBC which Im sure you have done as this is an area of boost loss.

[caminperth]

Well what made me take it off rather than check it is that the boost was all over the place.. was going up and down and in between.. all in one run on the dyno... wierd..

am going to hook it up again and try to calibrate it - this time properly cause i think it was a bit of a rush job before by a certain tuning house in perth to get the car to me in time.. if you saw the settings on the ITC you'd understand...

yeh a mechanic i know puts it in 4th gear at very low rpm and goes up a hill, it it pings a little then he calls it 'tuned' haha

but i suppose it makes sense cos thats a load that the car wouldnt normally experience. he says he never has a car ping under normal driving conditions if he sets it like that.

i prefer the more traditional methods but hey
