COIL PACKS

Plasma Direct is a factory replacement ignition coil system that uses a highpower amplifier built into the unit to increase spark current by two times that of the original equipment. The OBD II-compliant and CARB-approved Plasma Direct system produces a highly effective multi-spark discharge throughout the powerband, in comparison to the factory coil that delivers a single-spark discharge. The Plasma Direct's multi-spark discharge and improved spark energy yields improved ignition and greater combustion efficiency, all of which are beneficial for those driving high-horsepower vehicles—R-Magic, Garage Saurus, and M-Speed of Japan all endorse the Plasma Direct system.

Installing the Plasma Direct coil packs is a plug-and-play procedure that requires removal of four 10mm bolts securing each OEM coil pack in place, unplugging the portion of the wire harness that connects to the packs, then reversing the process with the new coil packs in place of stock. Take precaution not to overtighten the bolts securing coil packs or you can risk damaging the valve cover.

While our low- to mid-range horsepower and torque numbers showed marginal power gains, a close analysis of the dyno graph reveals gains of 5 hp and 5 lb-ft of torque in the high-rpm range, with the largest gains taking place at 7,500 rpm— proof that the Plasma Direct coil packs' multi-spark discharge enabled a more efficient combustion at higher rpm.

PROS

Having built a long-standing reputation for domestic vehicle tuning since 1985, Tennessee-based Hypertech recently introduced their hand-held, OBD-II, CARB-approved Max Energy power programmer to the sport compact market. The Max Energy Sport Power Programmer was designed to optimize a vehicle's factory spark and air-fuel curves over the entire rpm band, while allowing a user to modify the vehicle's electronically limited top speed and redline, check and clear engine diagnostic trouble codes (DTC), and adjust VTEC engagement points to customize the power band of an engine to compliment power adders. Hypertech's Max Energy also downloads and saves stock tunes, and allows users to revert back to factory tunes at any time.

Although the Max Energy Programmer was designed as a simple plug-and-play device, we recommend taking the vehicle to a tuning specialist with a dyno to recalibrate your engine using the programmer's features, in order to achieve maximum horsepower.

Impressive low-end horsepower and torque gains were accomplished with a 10hp and 25lb-ft of torque increase off initial throttle. Lowering the VTEC engagement point by 400 rpm enabled us to develop a smoother graph and gain 19 hp and 20 lb-ft of torque at 5,800 rpm. We also increased the redline to 8,400 rpm, but noticed no additional power gains. We recommend you keep your rpm at a more conservative level if you plan on keeping your engine healthy for long-term usage.
