I have a 1995 wrx, what I want to know is does it have a map sensor if it doesnt how hard is it to put 1 in? and also how hard to wire up to an apexi power fc? as i use 1 of the as well

Yep, yu have a map sensor,if you have a power fc,then you can change it for the later one,allowing higher boost,but it will need to be maped to run it.

where is the best place to get one and how much am i looking for it?

mit

Check you havn't got the later sensor already,as they often get fitted with the power fc. As said,you'll need to get the ecu mapped for the new sensor,so it'll cost £60+ vat,plus the remap cost.

the powerfc doesn't work properly with the later sensor as the scaling is wrong. the monitored boost is around 0.6bar lower than the actual boost if you wire in a newer map sensor..

it will work with the current map sensor to 1bar and a little beyond..

to go beyond that you need a boost control kit map sensor or a boost controller.

You really need it mapped as the standard map is fairly aggressive on the ignition timing..

Sorry, didn't realise that! Another reason to get the ESL then!

i do have a greddy profec b spec 2 fitted to the car to control my boost pressure anyway, will that help?

Jolly Green Monster

iTrader: (4)

yes sorted then

you won't have an overboost cut but the greddy has one if I recall correct

mit

iTrader: (10)

Yes it does,used to have one.It' didn't seem to control it well mind,as i would get fuel cut on cold days,even with the boost limit set.

so what do i need to do to go mafless?

Jolly Green Monster

mafless.. another ecu.. Simtek being very good and the best value for money etc..

so i cant do it on the apexi then?

not easily no.. there used to be a MAFSIM available but with the cost of MAP based ecu's like SimTek there is no point adding the extra hassle..
