Dunno if you've installed your setup yet or not. This is what I'm doing though.
Running a Greddy Emanage Ultimate as a piggy back off ECU. When the Emanage reads a massive drop in temp at the intake temp sensor (because nitrous is being injected), the timing can be pulled back or even advanced. When it reads the drop, you can also control injector duty cycles too, so you can adjust your fuelling for nitrous. Wanna do something similar for on-boost meth injection
As for the mechanical setup and activation side of it, You can do heaps of stuff really. Doing mine with a few fail safes. First you have to be at WOT, then run a nitrous fuel pressure safety switch so if fuel pressure drops below a desired PSI range then nitrous will shut off. If you want you could have an RPM window switch so that it would only fire during certain rev range too. Dunno if I'll do that. Last step is a button on the sterring wheel that has to be held down.
Safe and secure lol
Kw gain. Don't know sorry. My builds not even finished let alone have the nitro kitro kit on the way ^ ^
