Don't go there! :D I been doing the searches since 3pm this avo "not happy JAN!!"

I'd like your opinions on the following EBC's.. these are what I have narrowed my options down to for the GTR.

1. HKS EVC IV

2. Profec B Spec II "still trying to work out this difference between B Spec & B Spec II"

3. Profec A "Older but apparantley more features than the B Spec II"

a) I HAVE established that...

- dual solenoids are better than singles.

- all the units are fuzzy logic

- as informed by ben @ racepace the HKS EVC is the best he's seen?

B) I HAVE NOT established...

- whether fuzzy logic is good or not?? at this stage reports are 50/50 each way.

- is it safe buying a used EBC unit, considering the conditions of solenoids?

- if soleniods need replacing can I buy them seperatly for any of the avove EBC's?

thanks

What do you want to do with it? Run a constant boost? How much boost? do you want dual stage (normal and a higher mode via switch)? Do you want pretty graphs and digital displays? how much do you want to spend?

Answers those and ill recommend one :D

I use the EVC 3 controller...works well enough. It's hidden in between my seat and the center console, so i barely even look at it. It was second hand, so something did go wrong with it initially.

It's really not worth it if constant boost is the only thing u want from it. It really only contributes to the "wank factor" of my car when i think about it. It can maintain constant boost pressure better yes, but only marginally (I read that in a performance textbook). And I agree that I wasted my money on something a bleed valve could've done. I miss that missile switch :D Boost comes on the same way it did during my bleed valve days.

My car even makes better power using a bleed valve for some reason. The thing gives me boost cut now for some reason. I'm seriously considering a change back to a bleed valve.

I have a blitz dual SBC in my GTR and i am extremely happy with it, i know its not in your list, but i would highly reccomend it, has everything you'd need.. 5 boost settings, warning, peaks etc and timed boost (i think) so if you want more boost down the straight, set it to number 5 (from 4 - for example) and it will automatically go back to setting 4 after x seconds.

Thanks for the reply guys...

At the moment the Power FC is getting fitted & tuned. I have a turbosmart bleed valve runnin around 1bar, with the stock GTR turbos. I'm not looking at more than 1bar for the turbos at this stage until I upgrade. I guess all I'd like is constant boost, no fancy pictures/graph, & most important reliable boost with "no" spiking. Money isn't an issue as I guess when I take away some of the wank factor most them are about the same figure. Nengun have the Greddy Profec B Spec 2 for around $450 delivered. I really haven't heard any bad things about the profec Bspec apart from Ben at racepace who swore by the HKS 3 & 4 saying they were the only controllers not to spike on the gtr's??

Dude - I have an EVC4 (digital screen version) and it holds boost very very well. It also works with externally gated turbos as well as internally gated. And it works with single, twin, quad turbo, whatever.... Has a 2 stage function as well. I managed to install and tune it myself with no problems in 2 hours flat. And im not that knowledgeable with that kind of stuff, i just 'had a go'. Had my mechanic check my work and he was happy with it and mentioned he had put a few of them on GT-R's also. Im very happy with it. If you decide to get one, Im only too happy to help you set it up...

Hi meshmesh, since you are running a Power FC then I would consider the Power FC Boost Controller Kit, same (good) solenoid as the AVCR, use the Commander to control and monitor the boost.

I considered that at first, however heard bd reports re: single soleniods & twin turbos.. I think I have narrowed it down to the EVC 4.

PS: What's your thought about cam gear settings aof +4 & -6 degrees on stock GTR turbos running 1bar?

      Cleaning my wheels 😍

      Yeah, my moulds and seals are 32 years old now. I think I will continue to not use a pressure washer on it.

      I hear the old "I'd never use a pressure washer on my motorbike" BS in the dirtbike community too.  The only people that have had a problem from using a pressure washer on anything are the people that aren't using them properly.  If you hold the wand any more than 45 cms away from pretty much anything (radiators, wiring connectors, paint, etc) you aren't going to cause any damage.  We've had detailers wreck moulds and seals on cars at work before and the only reason why is they held the pressure washer too close and on the one spot for too long.  If you have 5% more brain power than a detailer then you know not to not do that and you'll never have a problem.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Mistakes were made, my R34 Story

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
