CDI Pencil Coil by AEM®. CDI Pencil coils are designed for converting your distributed ignition system to a coil-on-plug (COP) system using either a CDI module or 4-Channel Coil Driver. Users can combine CDI Pencil Coils with a CDI module to replace their factory smart coils, or combine a CDI, AEM Engine Position Module and stand-alone programmable engine management system to convert from distributed ignition to COP.
- Convert from distributed ignition to Coil On Plug
- Increases spark energy – ideal for high boost, high RPM and high compression engines
- Must be used with CDI module or Four Channel Coil Driver (two-wire CDI/Igniter compatible coil)
- Compatible with all standard automotive spark plugs (including threaded tip style)
- CDI Pencil Coil Kits include pencil coil(s), connector pin(s), pin lock(s) and weather seals
AEM makes it easy to hot-rod your modern fuel-injected, computer-controlled car. Instead of installing performance parts like bigger injectors and nitrous oxide and trying to make them work by modifying the harness, sensors, or adding modules, just install AEM’s Series 2 Plug and Play EMS and you’ll have complete control of your engine and driveline. The Series 2 EMS allows you to control every aspect of your engine, including variable valve timing, RPM limit, timing, adding larger injectors, boost control, nitrous injection, even anti-lag and individual cylinder fuel and timing trims. And it does this using your vehicle’s factory wiring harness and existing sensors. The Series 2 EMS is a real plug and play unit; it connects directly into your vehicle’s factory ECU harness and requires no additional wiring or hardware. It comes loaded with AEM’s Windows compatible AEMTuner software, which simplifies copying, viewing, and data manipulation. Just connect your laptop or PC to the Series 2 EMS with the included 10’ USB cable or 6’ serial cable, and start tuning.
The Series 2 EMS can accommodate 3 trigger inputs (Ref/Sync), up to 12 analog voltage inputs, up to 6 analog temperature inputs, up to 8 switch inputs, 2 Lambda inputs, and 2 knock sensor inputs. It has an internal barometric pressure sensor, and a user adjustable knock sensor center frequency. It’s capable of up to 12 injector outputs, up to 8 ignition outputs, up to 12 general purpose low side outputs, up to 4 general purpose high side outputs, and individual cylinder ignition and fuel trims.
Functions and features include groundspeed based boost target, staged nitrous injection, ground speed limiting, overrun boost enhancement (anti-lag), gear change ignition cut (shift without lift), stepper motor idle control, continuously variable cam control for 4 cams, main relay control, VTEC control, fuel and ignition rev limiters, “in-cockpit” global fuel trim capability, and gear dependent shift light.
Start-up calibrations are included to get you headed in the right direction. The AEMTuner software has colored tables and maps, includes a support pane to give you context sensitive help, and uses tuners’ actual calibrations to describe each function. You can graphically compare tables and maps for easy analysis, and internal conflict detection will alert you if obvious errors exist in the assignment of inputs/outputs. The included AEM data analysis software features advanced 3D graphics, and allows you to review and playback vehicle, driver, or engine data and overlay this data using charts, dash displays, gauges, or custom displays that you create. Maps can be password protected to prevent unauthorized usage or sharing.71.10
Brand: AEM Part Numbers:
John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
