Dual rain intake question for Jak

Hi Jak,
I recently read the post concerning the extra set of injectors for the c900.
I agree with the idea of inject with fuel not water, even tho water does the trick. But being able to control the 2nd set of injectors......problem i see is that running a 2nd lh2.2 ecu and switching it on when only needed sounds like trouble waiting to happen. Its like turning a computer on under load i think will cause more problems. Power up under load 13.7vdc possible power spike, boot up time, evaluation time of inputs. This is all before you start injecting fuel. These are some of the concerns i have running two ecus is almost as running 2 carbs balance would be crucial. Would you not be better of running something like a map sensor that at a certain preset valve, it would activate a solinoid to the 2nd set of injectors, open the fuel rail and rain like mad. Or leave the second set of injectors pressurized and switching the injectors ON via the map sensor. While still using the original signal from the ecu to drive both sets of injectors. These are just some thoughts looking forward to hear what you think.
