Put a post in about my type r couple of days ago, basically engine gOne so got my uk engine fitted asked question about what ecu to use was told the uk one with management etc, engine is uk 98 type r import 98 have all thE type r running gear on, 440 injectors turbo,maf etc so before I got round to installing uk ecu my dad fired up car on import ecu it did fire up and ran ( I wasn't there) and then just cut out now won't start it turns over but won't start any ideas? Is it worth putting the uk ecu on and key teams ponder etc then have another go or can I get it to run short term with import ecu any helps much appreciated as an stuck!!!!!

 

how did you get a typer uk ecu??
type r is a jdm only car

 

I have a type r ecu in my car mate but also have a uk Ecu what was told to fit ( I was away and my dad didn't) so it was fired up with the import ecu fella

 

youre post is sooo confusing. you say uk engine then type r engine.

if its a uk engine it wont be an sti and it will need the uk ecu

hang on you need to know what engine it is because your turbo, injectors will not work properly on a uk engine unless its just the block and you have used your original heads

 

Sorry mate right type r running gear and uk engine ( can't afford to replace Sti block yet) so quick fixing I have fitted uk engine in type r shell just wondered if own ecu will run it, well it fired it up but shut off and now won't start again??

 

use engines original ecu.

 

are you runnin type r inlet ,maf ,throttle, snsors etc

 

afaik, it wont work either way. your cams are different in the type r sti engine so the ecu will be running the wrong timing for the uk engine. you need to fit your original heads.

if the uk ecu was fitted , some of the wiring pin outs of the ecu are a different way round to imports plus the injectors of uk cars are 380 and the turbo is different.

the only way round it i can see is by getting an aftermarket ecu and getting it remapped or putting on your original heads.

 

I can put original maf, 380 injectors and uk ecu and turbo back in there as have all these parts Or I could just do what you say buy aftermarket ecu which am considering :-)

 

What failed on your original engine? Was it the block? If so why not just swap the block over and still use your existing heads/inlet/injectors etc. I know it's a lot of work but if you have all the bits then it should only cost you for new gaskets.

The only difference then will be the profile of the piston crowns, which won't make a big diference.

 

Yea the block failed mate, I still have the heads so it's a possibility but would rather get another Sti block for to put them on the uk engine is only a temp engine to use while I save for another Sti engine/ block etc

 

The UK ECU will not work in the Type R. the UK ecu will not allow the car to start due to it having the closed loop immobiliser feature which is not in the JDM cars. An aftermarket immobiliser will not solve this either.

What caused the block failure? If its a power increase that caused an STI bottom end to let go then your UK block is not going to last long at all.

Best bet is as eclipse performance has stated. Get an STI bottom in there with all the original ancilliaries.

 

Engine was standard mate just the person who I bought it off had not cared for it at all ( didn't know until I had it for a couple of weeks) So if I was to put my ecu and lock set into the type r with key, barrel transponder etc it still won't work you say?

 

compression and pistons strength will have something to say about that

 

99 immobiliser is not ecu linked.. in that you need the same ecu but the uk does require a uk wiring loom with the antenna as they call it within the error codes..

the 99 uk is different wiring pins at the ecu to the jdm.. you will have to move crank and cam and fuel pump pins to get it to run....

best bet although a pain to find is to source a jdm wrx ecu.. engine then same as uk but jdm wiring...

or just get it mapped..
