Hi Guys - I'm def not sure on ECU's, if for instance I can find an '02 JDM Sti ECU will it plug and play - so to speak in my WRX JDM or am I better off getting the standard ECU re-mapped later on after a couple more mods (IK and Downpipe) or will I need a new ECU altogether, any ideas greatly appreciated........Si.

 

im sure they can be swapped provided you have the software to rewrite the ecu imobiliser.

however best bet would be to remap your ecu. u know you will get the most out of it then, and because you will have to get the sti one mapped anyway to suit your car.

 

Simon you are better off getting your existing ecu remapped as this will give better performance than an STi ecu.

I am going up to Bob Rawle in October if you want to come up and see the results and the processes involved.

 

Defo better off getting urs re-mapped, the sti has a different turbo and AVCS heads so won't be right for your car without being mapped to your mods

 

Si, is yours an Auto?

This will also make a difference.

 

That would be great Tyron - if you don't mind I'll defo go to see what it's about

 

Yeah Ian it is a 4 speed - that was also in my mind, as the 02 Sti's are 6 speeders, with upgrading the standard ECU - do you know if an Ecutek or similar will give better results or is that purely software, as opposed to hardware

 

Thanks MrD n Turbodean - never done any remapping in any of my car's before and it's a minefield, uprate the existing ECU would be the best way by the looks of it and I'd forgotten about the imobiliser side of it

 

thanks TD - What is an AVCS Turbo - as according to the brochure I've found this car has them/it

 

No problem Simon I will confirm the date shortly.

 

active value control system! allows the cam shaft to advance or retard cam timing, on the fly. It does this through a series of oil pressure switches and solenoids


not sure what cars though

 

Sounds nicely complicated thanks

 

AVCS is the heads not the turbo, it's subaru's version of VVTI/VTEC as far as i'm aware its only on newage STI's.
Don't know much about WRX Auto's, but WRX's tend to have a TD04 turbo where as the STI7 had a VF30.

 

its just a version of variable valve timing.

keeps everything in sycro constantly!

 

Cheers Guys- top folks
