Looking to enjoy every bit of horsepower your car's engine is capable of producing? Then you need a power programmer. It's the last step towards excellent performance from your engine. So what exactly does this programmer do? It's sort of like an electronic version of a mechanic. The programmer makes adjustments to the ECU-that black box under your dash-to make your engine more powerful and fuel-efficient. So how does a power programmer work? All you have to do is plug it into the onboard diagnostics (OBD) port under your car's dash, and let it do its magic. The programmer automatically adjusts the air and fuel maps, ignition timing and valve and cam lift timing, redline limit to increase throttle response, improve acceleration and fuel economy. You wouldn't have to deal with the highly technical stuff to optimize the engine's performance. Isn't technology amazing? A power programmer can do all that by simply entering commands to reprogram the chip inside the ECU. Yes, the kind of chips that tuning companies sells to performance enthusiasts. But don't fall for all the hype. A programmer is a much wiser choice. Aftermarket chips have all been tuned on different engines, not yours. Thus, the chip may or may not work. Be a smart shopper.
