Vipec Issues

[Inferno]

Hey all, long time no post.

I've had a ViPEC in my S2 R33 for some time now, and its always been making this whirring noise since it was put in, was told that it was normal etc etc. Couple weeks back a friend of mine told me to get it checked out so I did, took it down to hyperdrive and they said it was to do with the ViPEC boost controller which was making that noise (initially thought it was the clutch and then the turbo) and a whole host of other problems which will eventually get sorted.

Back on topic, I had a 33 GTR boost solenoid put in when the ECU went in, so I was wondering if anyone else had a 33 with ViPEC experience anything similar to this, and if they were able to fix it, cuz if hyperdrive can't fix it i'd have to get a different aftermarket boost controller or a bleed valve.

its the boost solinoid pulsing on duty cycle. Where is it mounted? is it mounted properly? i.e. rubber mounted as to not amplify the noise. Best fix is to get hold of a factory bracket and mount it in the same spot as the GTR has it if possible or mount it forward of the engine bay behind the passenger headlight.

Thanks for the reply,

I'm pretty sure its mounted where the stock one was, but I'll get hyperdrive to check it out and suggest what you said.

If its making the noise the whole time then its setup wrong, should only pulse above preset load/RPM.

Another question...

My ECU firmware is 4.2.1, if I update it to the latest firmware (4.4.3) will that mess anything up?

Don't wanna do it if i have to fiddle with settings i have no idea about.
