Exclamation Ecu Help Needed For A Newbie!! Please!!

Hi guys, im fairly new to posting but here goes, I have a1995 Type RA STI, i took it onto the rolling road and got 301bhp on 2 runs.

The mods i have done are simple;

1. vortex backbox,
2. full decat from turbo.
3. induction kit relocated behind the bumper,
4. Irridium Plugs
5. Volt Capacitor (dunno if it actually done anything)

Now the problem hits, i was told by the guy who was doing the Dyno that i had the wrong ecu in the car, so somewhere along the line a switch was made before i bought it....

Can anyone tell me what tis ecu is for AND how its affecting my car!!!!

the codes on the ecu are:

6K
2251 AC 700
A18-000 D21 5919
UNISA JECS CORPORATION

Thankyou so much in advance, this has been doing me in for ages!

thanks for the reply pete, you seem to be the main man when it comes to scooby on the forum lol

no, he done a diagnostics aswel...

i got a 6k ecu, i think thats from a ver 1 or 2 sti, not type ra, from my undestanding the import 95 is a ver 4 ,which should either have a 7k or z5 ecu, does that sound right to you at all pete...

No I am not a font of all knowledge... sorry, but will investigate to see what I can come up with....

93 imports have a Z4 ecu. BUT I thought the RA's had a different one again. I will keep looking..
