bad FC again!!!!

[guest]

hEllo guys..a few weeks ago i just transplant my evo3 block to 4g67 block(vr4 piston)..my problem is now...my car FC is quite high...RM40-ron95 can only go around 130km......y ehh?any leaks? vacuums?do i need to tune? currently i'm on low budget(no money to buy emanage)..so is it possible for me to tune my evo3 computer box?need advice here...tq

btw...the mech also clean the TB since the car RPM have problem bouncing up and down...after cleaning the TB...RPM goes smoother to 1k...do cleaning TB will give effect on FC?

evo3 on ron95?? ecu detect knock n ignition timing pull retard and pour more fuel = rich or super rich. AFR <10:0:1...exhaust black smoke,stall engine idle..the solution get piggyback or standalone ecu retune back,dyno = problem solve :wavey:

remember that

evo 3 is set for high compression low ignition
vr4 is set for low compression high ignition mapping
of cos u need to retune , and google for this "boost leak test" do all the leak tests

and what flanker said is true :D

as far as i concern cleaning TB will not effect the FC, i have done it before,
i dont think u will be able to tune ur standard e3 ecu, u will need to have a piggyback to match with it, Safc perhaps at low cost

u may also rechip it if u find the right person to alter the map
