I just bought a down-pipe for a blobeye wrx, and it doesnt have a point to put the sensor in, whats the story there?, i emailed the company and they said the sensor goes in the 2nd decatt pipe, but i thought there was one in the downpipe to control something with fueling but im not sure, can anyone shed any light here.

cheers.

 

On the blobeye, there are 2 sensors in the up pipe and one in the 2nd decat down pipe. my down pipe is 1 long pipe with removes both cat pipes and has one sensor at the end of it. the pipe is correct.

 

ahh cheers for that, would it be worth heat wrapping it before i fit it ???

 

I didn't have any wrap when i did mine, some people do some don't. i'm sure someone on here can tell you the benifits of wrapping.

 

Yes definatly wrap it.

 

I hope to get a remap in the next 2 months, will it be ok to run with the decat downpipe till then, i prob will get rid of the 2nd cat too.

 

I will 'probably' be ok. You may suffer from overboost which is not good.
Dont drive everywhere on full boost and you should be ok til the remap.

what exactly is overboost,i can sortta guess form the name but, can u explain so i know for sure, and why is it bad

 

Overboost is when the turbo creates more than the target boost pressure.

Is it bad because the car is not setup correctly to run that amount of boost. The air fuel ratio will (more than likely) not be correct.
In some circumstances fuel cut may kick in to prevent internal damage.

 

ahhhh ok, i see

 

heat rap it to keep heat down in the engine bay and also since it joins the turbo to keep heat down at the turbo
also some say the downpipe can sound tinny and heat rap deadens the noise there.

 

is there anywhere u can get pre-written maps to reflash for your mods or close to mods, i have the OBDII cable/ software and wanna run my car like normal after downpipe install with out worrying about overboost, does anyone know where to look for these maps, i know about sites like openecu, im gonna get it mapped properly but cant afford it now, so its just to keep me going.

 

An openecu map will only cost about £300, i'd get it done anyway, or an Ecutek at about £550.

 

glad you mentioned it being tinny soundng as mine dose slightly warm and even worse when cold.sounds like ots blowing/chuffin, but i know i have no leaks. thought it might of been cos of sport cat so il be investing in heat wrap now me thinks...
