Other than controlling a water meth setup using a standalone ecu (motec or haltec) this is the KING of water meth injection. This is a pulse width modulated controller designed to work with direct injections cars (injection in each intake runner).

It references fuel pressure, boost pressure, injector duty cycle, inlet air temp, exhaust temp, air fuel ratio, built in failsafe monitor(it will bypass wastegate control returning boost pressure to wastegate mechanical spring if safe limits are exceeded based on user inputs ie engine leans out, egt too high, pump failure, water/meth flow restriction.

Custom electrical harness which allows for removal down the road without cutting wires after the initial install (See images-waterproof bosch connectors, includes wire color/numbers to install harness)

Nice, I assume you bought it?! I had my eye on this as well. Good price, just really bad timing with the holidays and such.

This is a steal of a deal and people should hop on this if they want to run a 93 file on available 91 gas or 100 octane on high quality 93 gas. If anyone is weary of installation and setup/tuning I offer remote assistance for install and the tuning (initial controller settings, review logs, recommended controller settings).
