Driving Aquamist 2c high speed valve with stand alone EMS
I have a highly modified 2002 Subaru WRX, with forged internals, 9:1 compression ratio (stock is 8:1), and lots of other supporting mods. I'll be installing a Tec3 EMS (using full-sequential fuel injection) very soon and have an Aquamist 2C ready to go in at the same time.
There are 2 possible ways I can control the high speed valve. The Tec3 has a staged injection feature which links injector drivers 5,6,7 and 8 with drivers 1,2,3, and 4, respectively, using a load/rpm map to determine when and for how long to open staged injectors. Using this feature, the Aquamist high speed valve would be opened in sequence with only one of the cylinders, since only one driver can be connected to it.
The second possibility is to use one of the General Purpose Outputs to drive the valve, which could be configured to fire the valve with every cylinder.
Are there pros and cons to these two approaches? Which one would be best, and what size nozzle would be appropriate for each (assuming 15% water/alcohol mixture)?
