Hi

I have a Escort Rs Cosworth (1995, EECIV)

The parts I already have are:

Graham Goode Racing Chip (GGR300BHP) capsule
Injector size 500cc/min(16ohm), FSE fuel pressure regulator 4-bar adjustable
Hybrid turbo by Garett T35 0.63/ar compressor housing 0.48/ar turbina housing
K&N air(trumplet) filter, Bailey dump valve(DV26), High pressure oil pump
Mocal Oil-cooler, High flow AC pump 200L/H, Magnex 3” full exhaust system
WRC style tubular exhaust manifold, Spark plugs: NGK, Intercooler kit with water spray

I wonder if you can help me.
I’m having a few problem with boost controlling. I’ve got the extra pressure from the turbo-system (it’s all time the boost overflow 1,8-2bar, or more in the full acceleration).
The turbo boost pressure is controlled by amal valve(+ECU-management system with GGR capsule).
GGR fitting instructions: the wastegate actuator has to be adjusted to a pressure of 10psi (I have tried with 6-8psi, and it’s also wrong).
I’m only plannning on running 20-22psi of boost (overboost), and after dropping back to 1,25-1,3bar.
I check all the connection, Ecu+Chip, wires, multipugs, sensors, wastegate, amal valve (no fault codes), and the necessary pipes(…etc.), also check a signal for amal valve, from the Ecu (with digital osciloscope). I can’t find the problem. The trouble is I haven’t got a clue where to start.
Also can you please tell, me if any other adjustments are needed.
What would you recommend?


Any help would be gratefully

Thanks
