Caution for anyone who is thinking about getting
DO NOT place it in the engine bay, after a few minutes it gets too hot and has a hard time sensing flow, or undershoots it. I mounted it in the trunk and it works great. Just figured I would save you guys the frustration.

Didn't someone say that if mounted in thou trunk that there is some sort of delay with the meth spraying? Just wondering i could have sworn a few people had that problem?

I also have it start to spray very early for that reason

Let’s say you’re cruising on hyw and downshift to do a run. It won’t matter how early you set your spray to emit to compensate then. There will still be no spray for a duration wile your revving high rpms. The only time an early start works for your target rpm is when your bellow your target rpm and load. With turbo lag it may be more forgiving then with an SC however.
I see your point but it still still senses starts to spray way before peak boost

The better, safer way to set up a water/meth injection system (WI) is to integrate it into your standalone ECU
I don't know the particulars of the AEM kit but if the flow sensor puts out a signal once a chosen flow is reached then you can use that signal to activate "auxiliary maps" in your ECU.
I think for the AEM ECU's they call those maps "Nitro" and they're activated once the assigned switch is triggered. The WI sensor provides that trigger and the ECU takes out fuel/ advances timing according to your tune. If the desired flow rate is not realized, then the ECU doesn't receive the Nitro trigger request and the car operates based on the "base" fuel/timing maps.
That's like a failsafe, if your tune has the base maps done to work with WI at all times, you are relying on the WI system to always work.
Also, your maps should not subtract fuel/advance timing until after meth injection is detected by the flow sensor. So you set it up to start injecting at around 5 psi, then you tune for WI starting at around 8 psi for example. You can still get a fail but you reduce the chances.

I'm still debating on whether or not to go water/meth and looked into the delay issue. Joey is correct, the new pump AEM supplies apparently solves the delay issue.
The new pump is a constant flow type pump where as the first gen pump was a pulsing pump. I don't exactly know why it solves the issue, but there's some video's online where you can see the difference in the speed and spray pattern differences between the old and new pump.
