Well I have had good results on the new fuel injectors (no resistors or P&H boxes anymore), car idles well and drives perfectly, I wanted to test the Stock Mazda ignition coils, lead set up and HKS amplifier (DLI) box and found it is far lower in capacity to the custom coil on plug full CDI system I originally made. It can only take less than half the water amount and the AFR needs to be set around 11.10:1 for it to reliably fire the mixture.

I am refitting the full CDI coil on plug system and will run the water injection system back up to its higher capacity after finding the limitation of the upgraded stock system.

With testing so far on 10psi inlet boost pressure on low water flow I have air inlet temperatures that are consistently 5 to 10 degrees above ambient temperature water temperature in all conditions is between 77 and 79 deg C (regardless of ambient temperature *tested to 36 deg C*).
