If you go for any solution don't forget to fuse it.
Before connecting the LC1, I've search for possible problem with that system and it came apparent that if the sensor needed to be switch on a while before the engine will be switch on, a few second usually suffice to cure the most of them.
On my car, C21, the delay is created by the time it takes for the fuel pump to pressurised the fuel system then to turn it self off.
