From my understanding, if you have the upgraded electronic wastegates, the ECU cannot control them so you have to have a boost controller to open them. If you have the standard wastegates the ECU can control them.

 

I have two greddy's one on my Evo8 and one on my P car.
I run 20 psi, 25psi,30,35 and 40psi.... all on different fuels... I dont think any stand alone for my Evo can adjust that by itself. I would have to run different maps and that would entail a laptop in the car...

My P car has it... Bobby's 4 p cars have... one of which put down 910 rwhp last week.
For those who have it... I doubt that any would go back to a static boost setting. I recall being on a non protomotive ecu ( 3 total) and in the winter my boost still went to 1.3+ bars... but during the summer it peaked 1.2 and dropped to 1.1 bars. So I guess the ECU was not doing the great job its supposed to... On the EBC you can actually dial in the overboost and get rid of it when the temp falls... or during HOT weather you can dial in the required boost setting so you maintain the expected boost.
The drawback is that if you do not respect the boost controller and ur car you will blow it up...
It would be nice to have a flashloader for different boost settings and or fuel... all mapped so u can just press enter and get going.... anything form .8 bars up to 1.5 bars. I know it is possible but Im not sure how wide the boost variance can be...

Greddy Profec B

 

What does everyone think of the HKS EVC VI. It's got LOTS of features that the Profec doesn't offer, but I'm not sure if they are really necessary though.

 

what features may that be ?

 

One feature I noticed first was that you can set the boost via RPM like the ECU can. Also there is a feature for overboosting that if it starts to overboost it shuts it down to a predefined boost level. I think the way the units work is different. I think the Profec relys on a solenoid.

 

the profec has the same safety feature with over boosting . im not sure i understand though what you mean by letting you set boost via rpm.. ??

 

Works just like it sounds. You can tap into the tach signal and set the EVC to control boost versus RPMs.. So theoretically if you made full boost (18psi, random #) at 3000 RPM you could set it to only make 13psi @ 3000, 15psi @ 4000, 18psi @ 5000 or whatever you'd like. Mainly its good for helping with traction. I was thinking in these cars it could work like the DME does and scale down the boost some as it gets higher in the RPM. Just like the DME with a Stage 1-4 tune.

 

bottom line is if you go to k24 hybrids do you have to or need a boost controller or not??

would like to know??

thanks

Tom it depends on which K24 hybrid you use.

K24/18G's, yes if you go with Protomotive
K16/24's's, No

 

then I guess it is a yes, thanks!!

 

It can be also done via Proto that you run without a EBC... you just have to make a decision what fuel you will run and then the WG springs get adjusted to that setting. It would be a shame to be at 1.1 bars on pump gas knowing that you have an extra 60HP ( around) without having the option of using it on the go.
What is more interesting is that a decent amount of you guys are getting into after market WG springs... some on K16s and most on K16/24 or k24s... and tell us how the car transformed including how much faster the boost comes on and how you can now get 1.3 bars. vs. 1.1. Well, a EBC does exactly just that.... it allows you to control the boost up and down to any given setting from the cockpit with a touch of one ****. Recall how many of you spent countless hours adjusting the WGs.... I do because I was one of them too. LOL
In any event, it's not for everyone and I do not suggest it unless your tuner offers the option... and you have a decent understanding of the function it offers.

BTW Mark, were the valves bouncing at over 8k, lol, love the avatar bro

 

 

Haha....
thats tooo funny....
