Dealers or car repair shops might call it a PCM or ECM reprogramming service. enhancing the PCMs original programming, which may have been excessively sensitive, failed to take wear on account, or otherwise had effects on the operation of specific sensors. The dealer accesses the latest software through the modem connection in the Mopar Diagnostic System, and feeds it through the DRB III scan tool into the vehicles PCM via the OBD II connector. Yearly and monthly access fees to OEM databases tend to be very pricey, but one-day or short-term access fees are typically available for $20 to $25. It's all done digitally with the proper access codes and input data. A proficient tuner can modify the flash to suit the owners needs by carrying out the following actions: You might want to think about reflashing the ECU after installing an aftermarket performance cam, bigger cylinder heads, a new intake manifold, or a fuel induction system to account for changes in airflow. 2. The technician can now press the OK button to proceed with the reflash procedure. Only an updated calibration can be loaded into the vehicle computer. Theyre now standard on all 2008 and newer cars and light trucks. To confuse things a bit more, the term electronic control unit (ECU) is often used as a generic term for any built-in system that controls multiple electrical features in a car. In addition to the J2534 pass-thru device or professional scan tool, reflashing requires: Computer or laptop with reliable Wi-Fi or a LAN/ethernet connection, Compatible cable to connect the computer to the tool, and tool to car, Access to the car manufacturers programming software. Reprogramming can improve spark plug timing and fuel enrichmentand can help boost pressure on turbocharged engines to squeeze out every last drop of horsepower. Update subscriptions can also be up to $800 per year or more depending on the vendor. If the job takes an hour or more, even the slight AC ripple produced by a standard battery charger is enough to cause a problem. The high cost for the right PCM flash tool might make DIY impractical. J2534 Reprogramming FAQs What is vehicle reprogramming? Thanks to the passing of Senate Bill 1146 in September 2000, vehicle manufacturers must now make this technology available to independent repair shops and individuals at reasonable cost.
