Blitz dual turbo timer (DTT)
 

Hi folks

my classic was bought with a blitz dual turbo timer installed. The boost pressure works fine on the display but the car shuts off immediately when the keys are removed rather than performing a pre set cool down duration. This occurs even after setting the required duration of cool down.

I am just looking for the obvious things to check as to why the turbo count down function seems not to work.

thank you

The one on mine has been wired so that if you turn the key one click the engine shuts off but if you quickly turn the key all the way and dont pause on each click the engine is kept running for cool down
