With the help of an AEM Wideband UEGO Controller and some close monitoring of the spark plugs, we were able to clean up the tC's rich condition and get it to idle perfectly - all before hitting the rollers. Before making an appointment to strap the tC to the dyno, we made more than a few of those hot laps around our neighborhood to get things close. The maps are based on engine RPM on one axis and airflow sensor voltage on the other. The tC was introduced first in the United States for the 2005 model year and then, beginning with the second generation in the 2010 model year, in Canada as well. Too rich? Follow the trace along the map and decrease fuel little by little in the highlighted cells. The Scion tC is a compact car manufactured by Toyota under its Scion brand from 2004 to 2016 over two generations: ANT10 (20042010) and AGT20 (20102016). Using the trace feature, we recorded dyno runs and hot laps on the street for easy view back and tuning. We concentrated mostly on trimming fuel across the board on Project tC. Besides fuel injector pulse width and ignition timing adjustment, there are also maps for adjusting the airflow sensor. The PC-based software also allows for a wider variety of functions for the e-Manage, including 16x16-cell maps for fuel and ignition. We're able to make all of our adjustments and import and export data right from our laptop. For one, we're not inputting changes or reading data from a little box stuffed into the dashboard. The unit is PC-tunable, which is a good thing. The e-Manage Ultimate does a bunch of cool stuff - stuff you might only expect from one of those higher-dollar stand-alones we mentioned earlier.
