I've just picked up my new 4x4 cosworth today. It has an uprated actuator, greens, 3bar map sensor, chipped.

It boosts at just over a bar (~1.2).

The amal valve is unplugged, so i plugged it back in but when i took it for a test drive it boosted right past 2bar and was still rising before I lifted off to avoid damage.


Is the amal valve faulty??? Has andoby had similar probs???


Any help would be very much appreciated.



Thanks

iirc if you run a car with the amal valve unplugged you don't run any boost.

With you fitting it back on and it's running so high,turn the boost down by lengthening the actuator shaft.

Better still get someone who knows about them if your not sure.

throw it in the bin mate and get a bleed valve

swerv

dont throw it in the bin

what actuator is on it?? the amal might have ben jetted for a spike so check for jets in the valve itself and also in the pipes coming off it.

mines like this. its not connected and it has a brass fitting in the pipe as a bleed valve i think. the guy from motorsport develpments kindly told me if its a superchip they dont use the amal valve and it was a primative way of stteing the boost yrs ago if thats any help?

Someone has disconnected your amal valve and set the boost by increasing the pre load on your actuator which is why you see massive boost when you plug it back in....sound like your chip is still amal valve enabled....

most stage 3 greens conversions run around 22psi of boost.....

The amal valve is primitive compared to something like air to air injectors but it can still be used to control boost reasonably well....

mine isnt connected up either so wat do you do wiv the plug wiv 2 wires
bit that plugs into the amal vave just leave it?
