hesitating over 6500 rpm
Hi guys,
HELP!?
I have a problem which noone here locally (Cyprus) appears to be able to solve.
Problem: Car is fine and pulls strong up until it reaches approximately 6500rpm.
i) From 6500rpm to 8000rpm the cars appears to have no power and does not pull hard and
ii) right after that you can feel the car run on 3 cylinders for a period of 10-20secs.
Background of the car
Car broke down a couple of months ago and engine was rebuilt 2.0 with forged internals, bedded in and now we are trying to tune it. We are trying to tune with an oem ecu using a 4bar map and tephra software at approximately 1,65bar boost pressure (24-25psi). (I purchased a Link G4+ plug in ecu and a forge wastegate to install soon. And see if its an oem ecu limitation issue.)
We checked:
Leak down test
Boost leaks
injectors
Plugs
Ignition coils and wires
Wiring
Fuel pump
Thoroughly the tune (currently tuned on an OEM evo IX ecu using tephra and an OMNI 4 bar MAP)
Car:Mitsubishi Lancer Evolution IX GSR MR FQ340 MY06
Engine mods
Manley platinum pistons race series 86mm 9.0 compression
ZRP rods i beams long-rods +5mm 56mm
Cylinder bore machined to 86mm
OEM IX Turbo (TD05HRA-16GM6C-10.5T (49378-01571))
ACL bearings
ARP L19 crankshaft studs
ARP L19 rod studs
ARP 2000 head studs
Fluid damper crank pulley
Tomei head gasket oversize
Ferrea valves oversize
Ferrea valve guides
Ferrea seals
Kiggly hla oil pressure regulator
Mac 3 port solenoid
HKS Kansai air box carbon
HKS panel filter
HKS hardpipe kit
HKS Superdrager exhaust
Decat-pipe
Fuel mods
Injector dynamics 1000cc injectors
AEM fuel pump 320
Fuel pump rewire kit with relay
Buddy club racing condenser grounding kit
NGK one step colder racing plugs
PLEASE help, i just want my car back.
Happy to answer anything that you want to ask.

Put the 560cc injectors back on the rail.
Plug the MAF back on.
Flash the oem rom back to the ecu.
Run stock wastegate pressure, see if the problem goes away.

Marios,
Unfortunately I do not have the stock injectors :/
MAF is plugged in. Car is tuned with both the SD and the MAF.
Although I have another set of 1000cc injectors. (tried them)
PM me your phone number maybe we can chat for a bit since you are also in Cyprus.
