I fitted a mates scooby ecu to my MY94 WRX RA and now have removed it. My car is still boosting to 1.1 Bar with my standard ecu which used to only hit 0.7 bar.. One of my mates said it may be due to the actuator being jammed. When flooring it in 4th and 5th gear it seems to be hitting some sort of cut out and jerks badly. Thought this could be hitting fuel cut but i'm not sure. Would 1.1 bar make it hit fuel cut? Anyone have any other ideas of what the problem could be.

Thanks

Anyone? Your help would be much appreciated.

Thanks

What ECU are you using in the RA?
"WRX/STi Saloon ECU's 2C, U8, W6, W9, 11.47psi boost held to redline. Fuel-cut @14.57psi"
I think that's relevant, so fuel cut is at 1bar....

 

Just took the car out for a test run again . I pulled out of a junction gave it full throttle pulls fine in 1st and 2nd then in 3rd on full boost there is a massive judder and miss . Surely this must be hitting fuel cut. My ecu is completely standard the car is an MY94 WRX RA. I did fit a freinds scooby ecu to it, but now have removed it. How is my car hitting 1.1 bar of boost and hitting fuel cut with a standard ecu.

Anyone help?

Thanks
James
