iam having alot of engine problems with my car and i found out it had a superchip fitted and wasnt mapped rite is it possible to remove this without renewing the ecu? the chip is wired into the loom outside the ecu

 

the super chip isnt a map its just fuel cut defender, if the car has a after market boost controller it will overboost once the FCD has been removed.

 

what else do i have to remove if i take the chip out?

 

i was wanting to get the car back to standard as iam going to put another engine in it and dont want this one to melt

 

Depends which version you have.. you should be able to see which wires it cuts, and it will then take power, ground and read a few other signal wires but not cut them.

Establish which wires it cuts and reconnect them and then cut the wires it piggybacks and job done.

I presume it is a box about size of a cig packet rather than the fuel cut defender which is about the size of a match box?

It very likely has a bleed valve fitted as well, it was part of the original kit.
The valve raised the boost level, and the device clamped the map sensor output. Remove both and you're back to stock.
Thankfully Subaru tuning has moved on since then!

 

You think that's bad... I remember early Renault 5 GTT 'tuning' - bleed valve and opening up the carbs main jet.

That's engineering for you.

 

its about the size of a matchbox with earth, map, ECU and positive wire and there is also a red light and green light on it. there is a bleed valve to so do i have to block any holes after i take this off? the garage that fitted it are well known for not doing a very good job of fitting them

 

id pop to a gaarge or put some pics up and that may help people explain it better for you but it shoud lonly take a garage that know any thing about tunnign a half houre to put it back to normal

 

the nearest tuning garage is a 12 hour ferry journey away haha. the place that fitted the chip here dont know anything about tuning they just fit the chips and make a hash of it plus the car drinks about 5 litre of oil in a minuite so cant drive. iam new to this so iam struggling to find out how to put a picture up

 

there is a picture of it

There are four wires, a live feed, an earth and the two wires which break into the map sensor output. You need to just trace them back and reconnect when it's removed.
Any doubt, give me a call on 01752 345880 and I'll talk you through it.

 

ok thanks for that Alan jeffery, would this be a possible cause of having so much engine trouble with the chip and the valve?

 

There is potential yes. Of course there may be plenty of other reasons!
