HKS EVC VI boost controller any good?

wrong,

ECUTek / ECU based boost control in my experience from the user stand point has always been superior to a third party / separate control unit. as long as your tuner knows what he is doing the ECUTEK boost control function will be superior than the HKS unit.

He was specifically discussing the refresh rate and it being too low for his tastes when compared to other options.

To Chuck's point, I also had read of this (see below). The opinion is that the frequency signal from the solenoid valve apparently isn't as strong as it could be to accurately produce a reasonable wastegate reaction time so it would be delayed compared to an EBC. Interestingly enough, I have been talking with Tony @ FI as of late and just brought this up as a talking point a few days ago with him since I had been interested in the integrated boost control from ECUTek. He basically shot the idea down and proceeded to tell me that at the SEMA show, Sebastian at SZ learned that ECUTek has figured out their software to the point where the Z should be able to utilize this feature as the GTR is able to (ECU differences) and he feels comfortable moving forward with it.

Until this, Tony said they have been using 4 maps as hjo1078 says below. 91 or 93 map, E10-E30, E30-E50, and E50+ so to a point you still have to monitor what tune you are running based on fuel in the tank. Now, it sounds like this won't be necessary with the new software that ECUTek has. You could still do the 4 maps if you wanted so you're not always running high boost I suppose.

Just the messenger here and know enough to be dangerous on this so don't shoot me!

Hopefully we can get further info on this.

He's done a ton of GTR's and [well, almost] a ton of Z's.

I contacted EcuTek support to find out just how and they pretty much told me to contact the tuner...so I got off that merry-go-round.
Evidently EcuTek can be utilized to monitor boost and electronically control the wastegate.
On the down side - I might be giving up the flexibility of selecting my own boost settings though - don't know how much of a good or bad thing that is.
Don't plan on racing it until the spring - so I've got a little time to get to know the car again.

I should say here that the car isn't being done by FI ...
The car had already transported to another shop before FI released their TT kit WR video.
As Agent 86 Maxwell Smart would have said --- " Missed it by --- That Much ---

"

Just couldn't bring myself around to extricating the car from another shop [once again] to ride the rails across the county.

Don't want to get too far off topic here ... but will find out more when the tuner gets back from SEMA.

Well thats what i named them atleast. I was told by visconti that i dont even need my boost controller anymore so i took it out. It is utilizing the solenoid from my boost controller still. I never really messed with my boost controller anyways and infact i dont even think i knew how to use it lol.

Yes this works on the 370Z. The only downside right now is it's a VERY slow circuit -- only 11hz. For good response you want to be around 24-32hz on the typical solenoid.

So would you install the HKS anyways or completely negate it?

it is all dependent on what solenoid you use to control the boost. most manufactures use the MAC solenoid, which is highly popular and inexpensive. that solenoid tends to work best between 31-33Hz

however there are other solenoids that are designed to work in the lower Hz like this unit

Humphrey Online Catalog 1533712VDC | CDS

like i said all dependent on user level and experience. MAC solenoids are easy to find and popular so i don't blame if it's easier to control with conventional controller *shrugs* factory GTR solenoids and GM solenoids work in the 20Hz range yet 50psi on those is no problem; see where I'm going with this? half the battle is proper plumbing, the other half is proper hardware. then the ECU just brings it together.

if I was tuning the car myself i would be using the ECUTek boost control function. I would highly recommend you have the tuner tell you what to do as their experience and comfort will highly depend on what they will want you to use. send sebastian@specialtyz.com an email he is the best e-tuner i know.
