I had my HKS EVC5 working for about 2 months now and when I just got my car back from a clutch install, it seemingly stopped working. I'm having the same problem as I had before which is the EVC isn't controlling boost. I've spiked over 23 psi a few times already not even at WOT (welll, not completely WOT).

My duty cycle was set on about 70 and I didn't mess with anything when it came back either. I checked all the hoses and they're all on there secure. I when I start my car up, it briefly says "error" real quick on the screen and when I unplug one of the connectors in the back it (from the stepping motor) and plug it back in it stays on "Error no.001"

Anyone have any ideas?

 

did u try resetting the ecu?

 

yep, i've had my battery out and in a few times in these past few days. each time I started the car back up, I lett it idle for a good 10-20 minutes too..

 

i only have error message on it when it gets really cold in the morning, all i'll do just re-start the car, it'll be fine on mine. probably for too cold sometime.?
i think NJ is way colder than here.?

 

Yup jsut restart it. I got this once or twice.

 

exactly what they said...
though do you think the people that installed your clutch messed with your car or settings? highly possible

 

i had that same error message once before. i turned off the power to the evc 5, and turned off the car. waited a few seconds and turned the car back on and the evc 5 and everything was fine.

 

I'll give this a shot guys and post soon.

Supa, the guy who installed it is my family mechanic and a good friend of mine.. I was thinking he might've nocked a hose out, but they were all fine. Settings were the same when I got it back.

 

nope, still the same. not controlling boost

 

anyone anymore ideas? my boost controller isn't doing ****

 

Is the EVC still showing ERROR???? IF not, and all the connections are good, try turning it on by holding down the pwoer button.

 

If this helps, my current mods that would play any factor in messing anything up are:

B&B 3" Turboback
HKS SSQV BOV (recirc)
SAFC

Took out my AEM intake.

 

Yeah, it's still saying Error no. 001 real quick when I start the car up. Also if I unplug one of those wires behind the control box and plug it back in, it stays.

 

How is it that when its cold EBC will give you error ??
Sounds very strange is this only for HKS EBC ? ?

 

Your other mods should not cause teh error reading.
