Just wondering if my ecu will support my mod's when im done with my project ? its a 98 ukwagon it has a my99 s8 or 8s ( cant remeber which way round ) ecu apparentley its mappable ? the spec will be a ej20cdb,650cc injector's, td05 20G ,walbro fuel pump,hybrid fmic,uprated fuel pressure regulator, decat down pipe and center , tubular headers and up pipe heat wrapped , uprated clutch anlight weight fly wheel. now thats the full spec just incase u ask lol , will i need an apexi power fc or will mine be able to be mapped propperley ?

If your car is a MY98 (2pot front brakes, older style front bumper) then it is possible to get it re-mapped but its not easy and most people just stick in an aftermarket ecu.

If your car is a MY99 which iirc was actually released September 1998 so there are some S plated MY99 cars about (4 pot front brakes with Subaru written on them and the later style front bumper) then you can just get it Ecutek'd by one of the usual mappers.

The 99 ECU can be remapped but I would have thought that fitting a 99 ECU to a 98 UK would be a nightmare. If what you say is correct then the Ecutek remap by a competent mapper should be able to handle your spec.
The expert with knowledge of ECUs and Ecutek capability that I would ask would be Bob Rawle of BRD. He could give you no nonsense answers.

well apparentley it has a mapping jack plug ??? and its ment to be a my99 ecu allready in there .So if it can be mapped its ok and if not new ecu time then .

If you are lucky your 98 car is actually a 99 model per Dave's post above and in that case it also has the 754 box per your other thread.

M535I

i think it is a 98 so my friend had sait to me pretty sure h is right , whats a 754 box is that any stronger ?

TY 752 boxes were in 93-98 cars and TY754 from late 98 onwards. In my experience, after 350 bhp the 752 box will break and sometimes a long way before that. Driving technique has a big effect.
The 754 box is generally stronger and has more strength in the casing.
Each gearbox has a sticker on the top of the bell housing on the starter motor/passenger side which gives a code like TY752 VBCAA for instance and from that the gearbox type can be identified. Also on your VIN Plate is the transmission code which, providing your box has not been changed, provides similar info.

oh right , well my box has been changed once befor at subaru so hopefully its been fitted with a 754 box .Im with the car the weekend so ill be able to verifie what it is .

easy way to tell if 98 or 99 model.. if the coilpack is in the middle of the inlet manifold on the top of the engine then i is a 98 and therefore the standard ecu is no mappable (easily).. if the coilpack is offset to the right then it is a 99 and the ecu is remappable using ecutek

coil pack is bang in the center phase 1.5 engine , but the ecu is a 3 plug i think but has a spare pug there as for what it is i dont know .Is it a case of just putting a mappable ecu into my car ? if so which one ?

are the plugs on the ecu yellow or blue black and grey?

yellow is replacement ecu only

some options here

Simon

M535I

the the block going into the ecu are yellow so thats me looking for a new ecu then lol , whats the white plug thats not connected to anything ?

Jolly Green Monster

iTrader: (4)

yes 98 then.. new ecu..

powerfc or simtek the main options..

Simon

M535I

no option of a std subaru one that i can put in to map ?

Jolly Green Monster

no, ESL are developing a board that will go in the original ecu of 97/98 as it available for 93~96 already but not ready just yet

Simon

M535I

oh right ok well mine is abit of a long term project so that might still be an idea ,my mate asked me why my ecu has a flash plug i thnk he called it any ideas ?

The ecu could have been changed already to a GEMS implant. only way to check is to take it apart, take a photo of the board and post it up

Standard MY98 ECU

thats not standard, got a picture of the skts, how many sockets, should be 3 on the ecu board

500

Nope sorry. God knows then as it was apparently taken from a MY98 WRX I owned that received a GEMS Implant after it had a 2.5 put in

M535I

i have some pic's of mine inside ill dig them out and post them up .

oops, it should have been this ECU, too many pictures of ECU's
