hi all. just got my first scooby and im loving it. its a 1998 turbo 2000 with decat and dv. will be looking into power mods later such as ecu,turbo,injectors and so on but for now im just gonna say.... a up me duck.


Hello welcome,

Dont worry we're not all that bad although gambit can be depending on what stage the moon is at, feel free to join in and get some pictures up !

Welcome mate. Do you know what it's mapped to now?

Welcome mate. Do you know what it's mapped to now?

dont think the ecu is mappable so wouldnt have said so. still got the decat in the boot after the bloke i got it off took it off for the mot. from what ive read its not a good idea to put it on without a mapp so im kinda in limbo about what to do about it.

You need an esl board added to the ecu for it to be mapped or a standalone ecu like apexi or mines, decatted it will possibly have overboost or spiking problems, do you have a boost gauge fitted?

dont have boost gauge fitted. pretty much standard. ive been looking at apexi ecu but not to sure on the ones im looking at are the right ones. whats involed with this esl you talk about? so its not wise to have the decatt pipe put back on then untill i get the ecu and remapp sorted.

Savage is your man to speak to regarding the various options as he has used both esl and the apexi setups,

Els boards cost about 300 new and are essentially another board inserted into the ecu to be able to map the classic impreza legacy & foz but it retains all the factory stuff as well, if you speak to esl or maybe duncan at race dynamix or andy forest they will be able to advise you on best plan of action,

I was told not to drive hard on a decat with no map but i want for the sports cat route instead

many thanks mate for that advice. will look into it next year but im skint at the minuite due to running a st220 as well and christmas coming up. but this will be sorted in the new year. just a little confused..... do i get the ecu sorted THEN decat or decat then ecu and remap. if you get what im trying to say.


Normally best way is to fit everything in the day of mapping then you shouldn't cause any problems, it's six of one and half dozen of the other though i've seen people with decats and no maps running fine. If you changed the air filter and decat ghats when you get more problems, they can cope with one or the other but not both,

I'm in same boat as you really was quoted 650 for a board and map by the late jgm but other things have got in the way,

You'll need to factor in another hundred quid for a fuel pump on top

im running a full decat and I don't get over boost lol

  • Author

call me stupid but what is over boost?

turbo putting out its true potential by free flowing induction and exhaust but not limited by engine management

  • Author

is over boost a bad thing then? sounds bad to me and i would i know if im over boosting? sorry for soundind like a newbe but its all new to me.


If your buying a apexi make sure it's the correct pin for your car ( 3 or 4 plug )

Seen a apexi on e bay for £170. Is this about thw right price for a second hand one and is it as simple as plug and play?

Is that just for ecu or does it include the handheld monitor thing ? You'll have to lift the carpet up in passenger footwell and undo the kick plate to find out what ecu pin configuration you have

No!

you need to have it mapped to your car / mods etc. Unless you have the software and map you need a specialist , Would say Derby way recommend JGM but unfortunately that's out the question now

yeah duncan is good,

HI sorry welcome to S.O.C.
