its turbo time

iTrader: (3)

I've got a dry setup that I've used with a timing tuner with n20 controls that works fine.

I am trying to install a hsw interface to add a little fuel up top and I can't get it to set up correctly.

It's installed correctly according to the instructions schematic (output from the timing tuner to blue wire, brown wire of interface to the ground of the relay) and I can get my solenoids to activate correctly with the wot switch but the "spray" light is always on which means that any fueling adjustments are always on regardless if I'm spraying or not.

Right now the calibration switches are on ls1, - activation, trigger power on.

I've tried several combinations of these switches to get it to work, but if I get the spray light to turn off the wot switch quits working.

The maf settings are Ls1 to. On, off, off, off.

Why is the spray light on all the time yet not activating the solenoids? And why does the wot switch still work if the trigger output of the interface is allegedly carrying current? (that's what the installation instructions say is happening when the spray light is on.)

Please help!

In case someone else has the same problem I figured it out.

I had to install this differently than the instructions say. I did not use the brown wire at all.

I ran the blue wire to the power wire of the solenoid, basically so that it gets voltage when I'm spraying. The configuration setting were, LS1, +, and power off.

Tested it several times and it works. It worked very well to get my afr right too.
