WI / Fuel controllers

[DuMaurier 7]

At present I have a fairly sophisticated W.I system using a mix of various parts from various manufactures. The actual water injectors are controlled by the E6K via the boost control map using one of the PWM outputs . This setup works well , but is only a two dimentional map (duty cycle vs rpm) and I would prefer a map that would plot dyty cycle against boost or an even better three dimentional map that would include engine RPM's to allow for better control. I am patiently awaiting the release of the FJO controller , but I'm still looking at using a fully independant lap top programmable additional injector controller , the ones withe the knobs aren't flexible and / or precise enough .Has anyone tried this ? , anyone know where I can find a controller like the one I described ?, I found two (split second and under dog..) , but they only go up to 25psi , I want something that would go higher to 30 or 40 psi. Any help will be appreciated .
