EVO 6 ECU Advice

Hi i just flew across to Perth and bought an EVO 6 and drove it back to S.A. But while i was there i had it checked out by Tokyo Motorsports where they looked at the mods that where done and suggested changes, one of the changes they suggested was to remove the Power FC ECU (With Controller) and install a EVO 7 ECU, they said that with my mods i should easily be getting 260+ KWTW but at the moment im getting 234-240 KWTW (315 HP) and said it is probably due to the ECU. Now i have done research on the Power ECU and it seems to be a really good ECU, so im am asking for your intel and advice as to why they would suggest going to a standard EVO 7 ECU and unlock it and have it mapped/flashed?

Thanx in advance for your help
 
Power FC is a pretty basic aftermarket ECU. And people run 700whp on the stock ECU's in the states so they're more than capable when a tuner knows how to work with them.
What mods does the car have?
 
a factory style ecu in term of keeping drivablility *poo*s all over most aftermarket options all the fidly finer details are sorted for you. so remapping a factory ecu can net great gain while keeping a factory feel,

Hows an ecu maintain factory feel?

Its literally determined by the tune. Not an ecu.

Factory ecu has good tuning capabilities with evo.

Obviously aftermarket has a few features you wouldnt get staying stock however
 
Thanx for your replys the mods its got are as follows:

GSC Stage 1 cams 264/264 duration 10.2/10.0 lift
Brian Crower valve springs
700cc injectors
255 walbro fuel pump
evo 7 gearbox and flywheel
stage 2 EXEDY Cerametallic Button Clutch
Power FC ECU with Hand Controller
Modified EVO 9 Turbo TD06 20G with straight intake pipe
Turbosmart Eboost 40psi boost controller
3" dump pipe off turbo with ffull 3" stainless steel exhaust with 1 muffler and high flow cat
Tein Coilovers
Slotted Rottors
Battery Relocation Kit
Customised Instrumentation Dials
SAAS Leather Seering Wheel
SHIFT Pillar Gauges
Short Shift and Gear Knob
G-Max 18" Rims Powder Coated Matt Black
 
For simplicty,

Ditch the Eboost, get a factory ecu, and tune it accordingly, will make easily the power level you will get out of the car, and will be hassle free, and wont have a huge ebboost gauge and hand controller in your dash, also you could sell them off and make a quick buck.
 
I have to through all the rego crap and when i get time i will post pics and try to work out how to change my current pic of my old car

But if anyone knows where to get an EVO 7 ECU from itll be appreciated.
 
why specifically a 7?
jimmy evo will probably be your best bet
 
@ 7R3N7 - The reason is Tokyo Motorsports are the ones who checked out the car before i drove it back to S.A and it was there suggestion to swap it for an EVO 7 ECU why do you have another suggestion i might think about

the only reason people previously used evo 7 ecu's is because they were tunable and tuner's hadn't cracked the earlier ecu's. now you can tune the evo 5 and 6 ecu's and they directly will plug into your car's loom. the evo 7 ecu will require pin modification before you can use it in your car so there is no real advantage to using a 7 (that I am aware of).
 
Do you have any pictures of the TME/VI?
PowerFC's are pretty dated and have a lack of time and effort put into tuning them on evo's.

Both the VI and VII will be fine, there is not much more to gain at the moment. Previously the VI ecu's (In Perth atleast) were unable to be tuned whereas the VII onwards were. The VI's ones were always able to be tuned by people in SA (Legacy Mitsubishi tuners etc) and until recently weren't able to be dual mapped (VII's were able to be dual mapped from early on). However I'm lead to believe VIGSR ecu's can be dual mapped now. I think TME ECU's are still trickier to tune/unlock - but I've been out of the loop for a while.

Let me check about the ecu's - I had two at one stage, a VI and a VII. Can't recall if I sold one or both of them. If I have a stock one left I'll ear-mark it for you.

Although, you'll have to see if you have a AFM still in the intake system. If you PowerFC runs off air pressure rather than air flow, the previous owner may have ditched the AFM (air flow meter). In which case you either need to get an AFM and put it back into the intake system. Or I beleive there is some way to run from air pressure from the stock ecu - but I've no experience with that.
 
@7R3N7 - Yeah they mentioned having to reverse pin or something like that but i still have the original EVO V1 ECU so what your saying is the v1's ECU can give me the same power production (mapped) as the EVO 7's can corrrect me if i interpreted it wrong.

@TPG - Thanks for that ill appreciate your looking for me and wait to see what you have thanks. And it is a EVO v1 not a TME i lined up two TME's to look at but one pulled out when i mentioned having it mechanically tested and the other was sold before i got in touch with him so that left me with the i got and honestly i am really happy with the evo i got. and i will organise pics soon.
 
yeah exactly the same. you just have to find a tuner who knows how to work with them. if you have the stock 6 ecu then use that 100%
 
@7R3N7 - Excellant i will look into it and S&J in S.A work with evo V1's although they are fundamentally subaru they know what they are doing dealing with MRT and the like.
i just dont know if the V1's ECU has already been unlocked or not so if TPG has one unlocked i might see about that.
 
'Unlocking' isn't like a phone where you need a code, they just plug in and reflash

there are shed loads of settings and features that a are nearly impossible to replicate from the factory ecu into a full standalone unit sure you can get them to drive like factory and never know the difference but there's things that you simply cannot perfectly recreate. like the behaviour of idle control and enrichment tables how the car reacts to different electrical loads a/c etc i'm in no way down playing the benefits of a stand alone aftermarket ecu hell i run one. when people talk about unes etc they mainly play with 2 table fuel and ign thats it. and on a factory style ecu thats all you have to tune. you might play with the boost control map aswell if your letting the ecu control that too.
 
I can confirm s&j know there *poo*. They've done most the work on the foz GT ive been building, however driven motorsport are really good too and im pretty sure they are closer to you also.
