hey folks... i'm thinking of upgrading my ecu on my p reg v3 sti.. i probably don't have as much cash as i would like/need to, hence why i'm after some advice on here

preferably i would like an ecu that can have different boost settings.. one for where i wanna go a bit mental and the other for when im jus driving about normally...

launch control would be nice aswell and if theres a way i can pop a big bang once in a while without antilag i would like to know about it

cheeers, steve

 

Simtek or Solaris but both will cost £1000+

 

i dont think i would be able to afford that, anything a little cheaper? i know you pay for what you get etc but i was hoping there would be a cheaper option

 

apexi power fc if your on a lower budget no anti lag or launch control though.

if you want a few pops and bangs you could just ask the mapper for some over run.

 

Speak to this guy www.jollygreenmonster.co.uk

 

my standard ecu has been mapped by jollygreenmonster already but when it was with the previous owner... is the over run potentially a little dangerous to damaging the engine or it just gonna hurt my fuel consumption?

 

How was it mapped as i thought standard V3 ecus couldn't be mapped?

 

no idea mate lol... all i know is its putting out 326bhp on surrey rr dynos abd all its had done is fmic and the jgm map. when i took my car into local subaru specialist for a quick winter lookover he couldn't tell me what ecu it was either and he can normally tell just from hearing them when the engine running!

 

Perhaps it would be wise to actually have a look at what ecu you have already as i'm guessing you don't have a standard one
It's under the carpet then a kickplate in the passenger footwell

 

i had a quick look and its a jecs ecu... they any good and what can i do with them?

..i see this is the standard ecu although from what i can gather they do aftermarket ones aswell which might be what mine is... it doesnt have jecs all over the ecu... jus on the sticker on the side and on the main bit facing the passenger its got like an l shape in a circle and 6s written on it... any info would be appreciated cheeers

 

JECS is standard manufacturer of impreza ecus perhaps there is something inside the ecu that isn't standard

 

Bound to have Simtek, or something else, in it (I think Simtek is a board that gets added to the OEM casing???)

 

should i unplug the ecu and take it apart and have a gander? i really wanna know what it is now lol... all i know is it has a jecs sticker on the side of the ecu with some numbers on..

 

If your inquisitiveness is getting the better of you, why not?! lol

You just need to remove the 'lid' to see (not worth unplugging, as you could disturb a pin-out unnecessarily - and that would really pee you off!)...

 

that would royallu pee me off haha.. when i take the lid off what should i be looking out for? never even seen my ecu until tonight.. let alone take the lid off and look inside it haha

 

You should see the serial number somewhere beginning, I think, "E1S96..." (if it's a Simtek).

 

i need a 10mm drill bit to get the top screw of tht kickplate out n i cant find it right now so probably best to leave checking it til tomorrow when its light lol... if it has got a simtek board on it though will this mean i can get als and launch control?

 

Yes to the ALS and LC query if it has a simtek then it will have a hole already drilled in it so a laptop can be plugged into it.

 

You could e-mail JGM with the car details and see what info he has.

 

i was thinking this... he should be able to do that as hes definitely worked on it... ill get in touch with him

 

It had an apexi powerfc on it when I mapped it.
