My Type R has a few engine mods Like Air filter, blitz nur spec R, decat downpipe, should it really need a remap now and how could i tell if it has already had one?

 

With a decat you will need a re-map if your ECU can be mapped. I am sure more informed people will be along with more specific advise

 

Yes it should really require a remap, you dont say what version/year your type R is though?

Its a v3 1997 type R

 

well i think it has a decat? Have the blitz nur spec full system. The cat's normally built in to the downpipe?

 

Yes cat is normally in the downpipe, your going to need an aftermarket ecu for your car though as you cant map the MY97/98 ecu's

where is the ecu placed in the car?, so i can check to see if its been changed.

 

In the footwell below the glove box. Pull back the carpet and it is protected my a metal plate that is bolted down.

 

Failing that a rolling road will give you a rough guide to the bhp of your car. I had the same mods as you + fuel pump and had no running issues at all with my car,just reset the ecu when the parts were added,and the car ran great.

 

How do you reset ecu on them?

 

Look under your steering coloum, you will see a pair of black connectors, and a set of green connectors- join them together , then switch on your ignition( not start engine). You will hear the fan, and your boost solenoid clicking.push the accelerator to the floor, then release it to half throttle position for 2 seconds, then release.
Start engine and drive car normally ( don't rag it),after a while your check engine light should start to flash at 1 - 1.5 second intervals , ecu is now reset. If you get random flashes it normally means a fault code .
You could also leave the battery disconnected for a few hors to reset your ecu . It is a lot easier to type info your looking for in the search bar , which would save me typing this out on my I phone lol

 

lol thanks anyway, removed my aftermarket parts which were apexi filter and blitz BOV for oem parts, but for some reason i have hunting idle, going to reset ecu and see what happens.
