What’s up with the poll?

You may have noticed in the lower right corner of your screen a small box that says “Poll”.  I am in the process of deliberating over what turbocharger pair to install next on my S4.  I have put some of my thoughts in these pages, but I was interested in learning what visitors to this site would seek in an aftermarket turbocharger if faced with some of the limitations I am.

Update:

I’m moving the poll to this post so that I can expand the use of the polling feature.

Results:

The final numbers for the poll are shown below:

TorqTune Setup

This is the initial results of wiring up the TorqByte WMI controller in my S4 and then running the Aquamist Flow Sensor off the WMI controller.

There will be a full write up on the TorqByte CM5-LT water-methanol injection controller coming soon, but for the time being I am working on getting it wired up and verifying that the wiring and configuration of the TorqTune software is correct.

What is illustrated in the chart above is the WMI pump duty cycle, as specified in the TorqTune settings, the pumps output current, and the resulting water-methanol fluid flow rate.  This is using the TorqTune software to trigger the injection while the engine is idling with no boost.

As can be seen, a moment after the current increases the water-methanol flow rate also increases, what I was expecting to see with a properly setup system.
