Unlike competing products, whose interface software is best described as "adequate," the ECU+ includes (at no extra charge) a complete Windows-based software package for datalogging and analysis. The ECU+ Windows software, which requires Windows 98 or higher, is the crown jewel of the ECU+ package.
On the left side of the (default) display, the ECU+ includes an Engine Monitor window. The engine monitor window displays the current value of all of the engine sensors and internal ECU+ values. The engine monitor display is always updated with the latest values corresponding to the displayed cursor. When doing a datalog live, the engine monitor shows what's currently going on with your engine.
Below the engine monitor is the fuel and timing map grids. These are color-coded to match the ECU+ configuration screens, and display the fuel and timing maps associated with the current datalog. The maps highlight the current fuel and timing map value in use, and auto-scroll so as to keep the current value in view.
Below the maps is an editable notes view, where you can save notes at datalog time (or later) about any unique features of this datalog.
The rest of the display contains a variety of graphing windows. These graph windows plot the value of various sensors verses time. When datalogging live, these graphs auto-scroll to the right, and can be scrolled backwards to display previous values. The X (time) axis of all of the windows can be zoomed in or out as desired, though all of the windows share the same X axis. The Y axis of each window is also zoom-able, but each window is independently zoom-able so you can see each signal to whatever accuracy you would like. You can zoom with the mouse, or via a pop-up menu. When you exit the ECU+ Windows software, your zooms and window placements are all remembered for next time.
Each graphing window also includes a crosshair cursor. The cursor tracks along each graph so you can see exactly where you are on the graph. As the cursor moves, the cursors in all of the other windows also track along, and the maps and engine monitor updates automatically. When you pause, the cursor pops up a tooltip to show you the exact value of the signal. By glancing at the engine monitor, you can see the exact value of every other signal as well.
The ECU+ Windows software also supports up to eight "overlays." With an overlay, the software will graph multiple datalogs on top of each other so you can see exactly how one run compares to another. The overlaid graphs can be scrolled independently with respect to each other, or automatically aligned for the ECU+'s street dyno feature.
(Don't confuse the ECU+'s Windows software with competing products, which often just give you one big graph with multiple displays slapped on top of each other. With these displays, time is pretty much the only thing you can change.)
The ECU+ Windows software also includes tabbed dialogs for configuring the ECU+ hardware. This integrated control puts all of the ECU+'s configurable settings just a mouse click away - there's no separate "map editor" with the ECU+ - it's all built in, and the same attention to detail is used throughout.
Also integrated into the ECU+ Windows software is the OBD-II functionality. There's no need to go to a separate interface to look at fuel trims or display check-engine codes with the ECU+ - just select the OBD menu item and you're on your way.
The ECU+ Windows software is really one of the best datalogging, control and analysis packages out there. Unlike competing products, which seem to consider the software to be an afterthought, the ECU+ package includes top notch Windows-based software that can get you up and tuning your car right away.
