To perform this tuning, the TEC-II features new Windows-based software, appropriately named "WinTEC." The WinTEC software features a unique "Tuning Wizard" that allows the tuner to enter various engine parameters (such as number of cylinders, number of injectors, BSFC, peak power and peak rpm) specific to an application. The Wizard then takes these numbers and calculates an "ideal" fuel injector flow rate. After this calculation, the user inputs the actual injector flow rate being used on the engine, and the Tuning Wizard establishes both the base fuel curve and the base timing curve. These curves can then be manipulated with 64 data points throughout the engine's operational range. Additionally, the software features cold start enrichments, throttle rate-of-change enrichments, closed-loop control via an oxygen sensor, idle speed control, knock control, fuel pump control, rev limiters and a tachometer output. A general purpose output is also included, and can be used to control almost any rpm-activated electrical device.
In the next few months, a new version of WinTEC software will be introduced, featuring an automatic fuel calibration option, based on the air/fuel ratio reading obtained from the oxygen sensor. The user will only have to enter the desired air/fuel ratio at different engine operating points into the software, and then run the engine through its operational range. After running the engine, the computer will then "learn" to create the correct fuel injection parameters to meet the desired air/fuel ratio. After the initial calibration, the vehicle can be run with or without the oxygen sensor.
The interior, which retains...
The interior, which retains much of its OE components, testifies to the car's roots as a street/strip proposition. An old-school T-handle puts the 'glide in gear.
So how easy is it to install a TEC-II? About the only thing necessary to adapt a fuel-injected engine to a TEC-II engine management system is a crankshaft-mounted trigger wheel. Electromotive utilizes a 60-tooth trigger wheel in conjunction with a magnetic sensor to obtain engine speed and position, which are both included in the TEC-II package. Mounting the trigger wheel to an engine is generally not difficult; typically, the user can mount one on the harmonic balancer or the crank pulley. For some applications, camshaft-mounted trigger wheels (with 120 teeth) are also available.
Electromotive's trigger wheel design was born out of the desire for the highest possible spark timing accuracy. With Electromotive's trigger wheel, 1/4 spark timing accuracy is available, which is the highest resolution available in the aftermarket. Along with the high resolution afforded by the crank trigger, the coils are all impedance-matched from the factory, and are controlled by a feedback electrical system. The feedback system allows automatic, precise dwell control at all engine speeds. The TEC-II has a proven track record and with the new software, it is becoming more user friendly by the minute.
