Hi,
i have a 2002 wrx which is currently standard.

I have a prodrive back box, prodrive secondary decat pipe, and prodrive sportscat pipe...

if i put them on do i need a remap or will the standard ecu and map be ok?

thanks

 

Yes to be safe - you'll be making a noticeable improvement to the airflow

 

is it something to do straight away?

would i cause damage if i didnt get it done for a few..4ish weeks?

 

The decat and sports cat will reduce resistance of the exhaust and could cause the engine to potentially run lean as a higher boost level than normal could be achieved and cause a detonation and failure of the bottom end of the engine. Most cars will be fine, some could/might fail, if you want to safe but want a bit more noise just add the prodrive back box and then get the other bits added and then get a remap asap.

 

so the next question then...wheres a good place to go for a remap?
is there anyone local in the milton keynes area or is there such a thing as a mobile service?

duncan at racedynamix is mobile based northants so not to far from u....top bloke he maped my 2004 sti made a massive improvement and mines completly standard apart from backbox dump valve panel filter...

 

It shouldnt be overboosting too much at the moment but to really get your moneys worth out of the mods you have done, then I would recommend remapping it along with fitting a 3 port solenoid.

 

I'd be happy to come out to you to remap the car to suit your exhaust mods.

As Duncan suggests above, a 3 port boost solenoid would be a worthwhile mod. I have Prodrive solenoids in stock.

 

TBH the only way you will notice an improvement will be a re-map...........an open source one will suffice.

Without a re-map All the ECU will do is compensate for the airflow and tootle along it's merry way at around the factory 215PS with a little earlier spool and a different noise.
