Bro kariayam,
That is a very detail and clear explaination. Thaks bro. Actually the ebc is free gift that is why it is installed. That is the perfect answer why mine is 1.1 bar max only. Pity my evo cannot unleashed its full power
I understand the boost setting. I will set the value for 1.38 bar. But for the gain, what should i set? Dont really understand about it.

And that is why i m worry about cruising at high speed but i guess if we have enough gauge than we can take early precaution to slow down.
For me the best cruising speed for my evo is 140 - 160km/h.
By the way anybody have the m7 boost controller manual? I have lost mine
...............and please dont blow the engine
My suggestion is just disable the boost controller or just turn it off if possible.
Why??? =
Spike means the boost will overshoot to 1.4 bar for a very short period of time( 2-3 secs) before coming back to normal boost (normal boost maybe 1.1-1.2 bar if i'm not mistaken) as from the factory setting.
You will not want to set the boost controller to 1.4 bar, as this only make your boost becomes constant at 1.4bar at all time and it's not healthy for the engine and the turbo itself + the fuel system is still stock + stock ECU.
REMEMBER: the factory setting only SPIKES to 1.4 bar, not sticking to 1.4 bar all the way
The easiest and best way for your solution is Just get your boost pattern re-set to factory setting to unleash the real potential of your e9 by disabling your boost controller.
Answering your question on gain setting, you have to do trial and error. you may start from the lowest gain, and try to increase it step by step.Find an open empty safe road, and try to push your car at high gear..(may be 3rd or 4th gear....and it's at your own risk too...)
You will see how fast the full boost is built up.. stop increasing the gain once you see the boost starts to overshoot above your earlier boost setting.
Huh..hope this clarifies......................and please dont blow the engine

can be a guideline to those want to install ebc later
cheer 
I dont really understand how to use the boost controller. If i set the boost, actually the mechanic set it, to 1.0 bar, does it mean all gear will be at 1.0 bar or will still varies according to gears?
There are 4 levels to set in my m7 boost controller. Level 1 1.0 level 2 1.1 level 3 1.2 and level 4 1.3.
If i use level 1, so it wont go until 1.3 right? But it happened to jump to 1.2 bar. Never experience 1.38 or 1.4 bar.

Yeah agreed, good explaination.
Bro kariayam,
Ok if i understood the boost controller function correctly, it will limit the boost level. Let say if i set it to 1.4bar. Since the standard boost for ix is 1.38bar and will spike to 1.4bar, that means it is a correct value to set am i right? It still allow the ix boost to be in its standard range, 1.38 spike to 1.4 and drop to lower bar 1.2 or 1.3, am i right?
Or are you trying to tell that if we set the boost controller to 1.4 than the boost will maintain at 1.4 and will not drop after that?
I have read a 52 pages thread of evo ix in zth, another point of ebc is to avoid a high spike since 2005 evo ix with magnesium turbo have the tendency to spike until 1.6 bar. Therefore if we have ebc it will limit it to the boost we set, let say 1.4 bar only and will not cross it.
But does it mean that the boost will go or maintain to 1.4bar instead of 1.38 spikes to 1.4 and drop?
Thanks a lot for making this thread a good technical thread to help new evo owner like me.
Bro aycy thanks i will search for it.
Kariayam,
Sorry for my ignorance. Try to learn from you and sifus here hihi
I hink i got your point. If we set it to 1.4bar, it will maintain 1.4bar instead of dropping abit right? Whereas a turbo should spike to 1.4 and drop.
this is what i understand what bro kariayam said, if u set 1.4bar,it will maintain 1.4 but u need to see ur gain setting, if low gain should be no boost spike but if u set ur gain higher then it still have boost spike..maybe the previous post u said "If i use level 1, so it wont go until 1.3 right? But it happened to jump to 1.2 bar. Never experience 1.38 or 1.4 bar" maybe ur gain a bit higher so that it still can spike till 1.2....correct me if im wrong..im also still learning so we can share our undrstanding
====>i take note from bro kariayam sentences "Now we will talk about gain setting. If you set the gain setting too high,you will have the risk of boost spike. i.e: if your boost setting is 1 bar, then you set too much gain, there will be possibilty the boost will spike to above 1 bar before returning to 1 bar"
Bro one shot actually all the setting were done by the mechaninc. Have not try playing around with it. The manual also in japan and not much can find in the net for m7 products.
We are lucky to have kariaayam to teach us
I need to learn the gain thing, to set boost level i think iunderstood already. Bro aycy i cant find the manual la, if possible can u attach here or email me ?
There are so manythings to do with our ix. I m going to sunway after his to look around. Looking for a turbo timer, may be apexi.
dont forget to update here so we can learn n share together...
Hi bro kher
Yeah the ACD pump is one of the major problem for an evo. If u use the diagnose machine is will show code 81 and 82, acd pump failure.
The cost is high but i believe it can be found here but half cut la. Or can order from Mitsubishi Malaysia.
The problem always occur due to improper bleeding process. Sometime the pump is okay but there is air in the line, by removing the air properly, the system will be fine. To know the acd system got problem is when all the 3 ACD lights turn on at the same time.
