A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface.

AEM’s TRU-BOOST Gauge-Type Controller is an electronic boost controller that combines the simplicity of a manual boost controller with the added ease of adjusting boost levels through a gauge interface. There is no external interface required for set up, and it is fully functional right out of the box. There are no gimmicks or special software programs included. If you want more boost press the button on the right of the gauge face, and if you want less boost press the button on the left of the gauge face. It’s that simple, and IT WORKS!

The new HKS EVC has improved boost stability for maintaining pressure at high RPMs providing increased top-end power, and a new mapping feature allows boost pressure to be precisely tuned for throttle + RPM (or vehicle speed). The new EVC also offers a selectable kPa or PSI unit of measure, and a unique warning feature where if over boosting occurs, boost pressure can be programmed to drop to a user preset level.

The PRofec B-Spec2 integrates all the basics of an electronic boost controller, with additional useful options. Use the built-in boost gauge (psi or kPa) to tune in a Lo. & Hi. SET % to raise the boost pressure, then optimize consistency and response with GAIN % and adjust the START GAIN to set initial wastegate response.
