Hello all!

I have above EBC in my car set up by Alex knight!

settings as follows... car has blitz nur spec & aussie down pipe
[low] 34%
[high] 44%
gain 10% (low and high)
set gain 0 (low and high) full boost starts at approx 3300rpm
warning 1.2 bar
limiter 0%

this holds boost well! however I just turned set gain up :D now I spool up at 3000 rpm!


just fitted same EBC to boosterxb's car and settings are... car has cat still fitted & mongoose system.

[low] 35%
[high] 47%
gain [low] 16%
gain [high] 17%
set gain (so far) 0.6 (on both high and low)
warning 1.2 bar
limeter 20%

Boosters car seems to be holding 0.9 bar and 1.1 bar preety well after 4-5 runs it didnt move more than 0.03 bar above .9 or 1.1 so i'm happy but what just getting me slightly is the set gain option!

it says it brings on spool early which i have proved to my self playing with mine, how high should I take it roughly! would 0.7 bar seem right if no spike occurs?

and with regrds to limeter! is 0% useless (mine) and 20% to harsh? (boosters)

My metho of setup...

I set his cars boost to 30% [low] and got 0.8 bar from approx 4500rpm - 6500rpm
I then went to gain settings!
his boost was rising slowly as the car reved harder! so i kept moving gain plus until he got full boost at approx 3500rpm and it was holding steady up to red line!
i then moved setgain up to 0.06 bar and this brought boost on at approx 3200rpm

all readings taken from peak values! as boost gauge on controller say approx 0.1 bar less than peak!

conclusion of questions...

1. [Set gain] would 0.70 bar seem right if no spike occurs so as to bring boost on at earlyest possible rpm?

2. With regrds to limeter! is 0% useless (mine) and 20% to harsh? (boosters)

3. Do any of his settings seem odd? (my first time setting one up :wink: )

4. Was my method o.k? :?

5. Should I start his from scratch with a different method? :roll: :)

cheers sorry it's long tried to make it detailed and logical !

Andy,

Not sure if I can help but its probably fair to say every car/engine/turbo/EBC setup is different. You just have to try experimenting to see what gives the best results. When I had my Blitz EBC the gain was set really low to avoid boost spikes. Whatever you set on a warm day will need to be turned down as the weather turns cooler as you will find the colder/denser air causes the boost to rise really quickly and you will almost certainly get a boost spike. Clearly this isn't likely to be a problem with the weather we're having at the moment but later in the year you will have top keep a close eye on things and readjust as appropriate.

HTH

Cheers mate! Yeah i got the weather thing under control! :-)
.
Amazing how much difference a bit of sun will do to the air!
.
I think i figured it not now! After some more research!
I just dont know what happener when the boost goes above set limits! Meaning if limiter was set at 20% how does it react in comparison to how it reacts set at say 5% !?

The set gain (or start level as it's much more understandably named on the profec E01) actually determines what boost pressure the EBC needs to see before it even begins to try and control boost

Below the level the solenoid is left closed for maximum spool and above this the EBC starts to control the solenoid

I never had any issues with mine set at 0.7 bar :D

The limit function controlls what happens when the controller hits the limit LOL

Specifically it determines the limit activity.
if set to 0 it will attempt to hold boost at the limit level
If set to (say) 10% then it will try to drop the boost by 10%

I always had mine set to a 1.2 bar limit with 10% limiting
This should attempt to drop the boost back to 1.1 bar if it overboosts
On track I usually set this to 50% limit so that in the event of overboost it switched back to actuator pressure

Cool, the percentage of limit was getting me,
.
As it does not say anywhere how or what the boost control will do set at 20% or 10% cheers

The Blitz Gain control works in a different way by controlling the RATE at which boost pressure rises. It has no effect on when the EBC starts functioning. Not all EBC's function the same so I can't comment on how the others work. Even the same manufacturer changes the spec from time to time e.g. HKS

This is how it works on my Greddy though

Given the nomenclature and units of measure (specifically it's stated in bar, not percentage where gain tends to be set in %) I'd assume it's start boost. This is why a huge difference can be made with the set level to bring spooling forward

The E-01 also has gain as well :D
I'm probably going to refit it in all honesty as it's a better EBC than the Blitz

I've got it running very well now! Got rid of the creep in high mode! Although i still get some in low! Better there though!
.
It spools at around 2900rpm so it feels so much more aggresive than it did before! :-D
.
I think i might get it on the rollers for an hour just to see what the curves are like now! And see if i can get it fine tuned in a little more!
.
The only thing that bothers/confuses me now is that both my boost gauges (blitz and greedy ebc gauge) read at 1.0 bar and 0.8 on high and low respectfully!
.
However peak values always show 0.1 bar more! Thus giving me peaks off 1.1 and 0.9 bar!
.
Why is this ?
Found the same when i set another one up aswell?
.
I guess i should always set up using the peak values!

Sounds as though you are seeing a spike when flooring it

This **usually** happens when you put your foot down at > 3500(ish) rpm when the turbo is able to spool instantly and aggressivly. This is quite different from the "normal" swetup routine of flooring it at 2000rpm and watching the boost rise

You could try lowering the gain a little to bring on the boost a little slower.
I ended up with mine set to < 10% and used to get very very few very small spikes.
Also used to lower the gain on track to bring boost on more slowly for more predictable results exiting corners but the difference, apart from spikes, seems very small

If a low gain doesn't help then you'll have to consider lowering the start boost level to give the solenoid a little more time to react

Can you record with the Blitz gauges? Some can IIRC which might be a very useful tool ;)

I get a constant reading of 1.0 bar from 3000 rpm right up to the red line on both gauges!

My peak value then flashes 1.1 bar

if i let my foot of the pedal at say 3500rpm my peak is 1.1 even though gauge read 1.0
and if i let pedal up at 6000 rpm my peak is 1.1 even though gauge read 1.0

oh and I did set my car up starting fromm 2000rpm in 3rd and watching the boost rise !
it does not lift above 1.0 bar on the gauge no matter how aggresive i am with it! but peak value is always 0.1 bar higher
