Water injection control?

[LS1M]

Is there a tuning solution out there that'll allow you to control solenoids like water injection or nitrous? I think Unichip will but not sure about any others. What about logging oil pressure?


Thanks!

ECUtek would be the obvious one, custom map outputs similar to that used for turbo boost control etc.

So... If ecutek is a reflash of the stock ecu, how can it operate a solenoid that doesn't exist in a stock ecu? Are there spare inputs & outputs on the stock ecu that you can wire the solenoid/pressure sender to?

My guess would be using the wiring for say, the 2nd O2 sensor or EGR valve and wiring a solenoid to that.

ECUtek can reuse the Rear O2 or CPC sensor as external inputs and you could use this to create a low level warning for water/meth etc and create a map that would increase performance when spraying etc.

The CPC solenoid output can be re-purposed for use, just like they do for boost control.
