Good, glad to hear it's sorted. And not surprised to hear about the pipe, I think they were homemade from a couple of rubber steering gaiters. I have long since replaced mine with a proper fuel-resistant pipe.
As for the immobiliser I think you are talking about an after-market one. The Superspec ECUs were internally modified to disable the built in immobiliser before they were issued with the kit, Unfortunately the firm involved, like RH Engineering, are long gone, so I am not sure what we SS owners do if we need a replacement,
