Hi all

what's the Evo 7 Boost?????????

Is it same as evo 8 or not???????

and does anyone know for sure when the ECU in the Evo VII cuts out?

 

I think standard boost is 1.2-1.3 bar and fuel cut is just over 1.5 bar.

 

where are you guys ?

please help

 

Mine was japanese boosted at 19 to 20psi and then after some while it started dropping but i gues it was just a bad cheap guage

wael

 

my blitz boost gauge showed 1.2 bars when my car was standard-ish

 

It should be 1.2 Bar and goes down to 1.1 at higher revs. Fuel Cut ist somewhere about 1.4 / 1.5 Bar.

 

Fuel cut meaning the fuel stops going to the engine, or the fuel pump isnt sufficent enough for that much boost so it just runs incredibly lean?

 

the ecu cuts fuel to stop any damage from too much boost

 

stock mine was running 20psi....
with just exhaust.

 

Thank you guys for replys


I just bought these parts ..waiting to install :
1- Blitz NUR Spec R Cat Back.((there is no hole for the Oxygen Sensor > Is it important to install it or not?coz the exhaust is for the JDM Spec evo and JDM Spec Evos has no Oxygen sensor in the cat back))
2- Fujitsubo Downpipe.
3- Helix Cat Delete.
4- A'PEXI Boost Gauge.
5- Hallman MBC.


I'm planning to increase boost to 1.4 or 1.5 BAR with the stock ECU ... do i need Fuel pump,Fuel Regulator, HKS FCD,,,etc ???


what do i need to run 1.4 or 1.5 without detonation at all?????

 

probably just the fuel pump to be on the safe side.
injectors should be more than sufficient.

my evo 7's stock ecu allowed me to boost up to 24psi before cutting.

also 1.5 bar aint that much...i would boost 20psi stock and at night it would spike to 21psi. so you should be very safe.
