SOS Please help!!!
#1
Is there anyone out there who could help me please. The problem I am experiencing with a 1995 Jap WRX is that it cuts out the acceleration between 4000 and 5000 rpm. If I suddenly want to take off it will quit accelerating at 3000rpm but if I gradually build the acceleration up slowly it will go to the 4000/5000 rpm and and give up acceleration. I also notice it is running without the turbo kicking in. When travelling at constant speed of roughly 60 / 80mph the accleration will shiver... I am confused... what could it be... Please help :-(

It came with so many electronic gadgets that were removed at the SVA centre in order to pass the tests. The only mod it has remaining is the induction kit. First I thought it was a loose earth wire, but when that was secured... still the same problem.

Pardon my ignorance but what is the FCD. Also to let you know which may help is that I had a full service done to it which did not solve any problems, the air flow regulator was replaced, I chnged the ECU (from another same year and spec WRX) and had the coolant resevoir changed... still nothing??? :-(

It difficult to explain... the car does accelerate, but not under the influence of the turbo it seems. Because when the turbo kicks in, one should feel a sudden burst of energy... but even past the 3000rpm limit when the turbo should come alive... it doesn't. So that's why I suspect the turbo is not even coming in effect. I can't really hear it whiring but that may be because the exhuast is loud. As I accelerate the velocity dies... and then catches up and then dies... It's like when you reach the limit on a restricted car. (But this is derestrcted)

FCD - Fuel cut defender, this absorbes the signal from the ecu when the max boost level is exceeded. My car was running 1.3 bar because i have the fuel controller (this should be ok) and at that point am using 25% more fuel - the standard ECU will not allow this boost on my car MYOO - so I need the FCD to fudge the ECU.
This is hopefully a silly question but you havent got loads of smoke coming out of the exhaust?!
It could be the MAP sensor otherwise you need to get a donor car to try all the obvious bits.

Yes Justin... checked all of that... I just can't understand what it could be??? I am quite distressed. If I take it to a Scooby specialist they will charge £000's for a £50 job!!!
