By 1995, most GM models had the flash reprogrammable PCMs. It is all done digitally with the proper access codes and input data.įollowing the Geo Storm, GM began phasing in PCMs with flash reprogrammable chips in a variety of cars and trucks. PCMs built with EEPROM chips can be reprogrammed in a matter of minutes without having to remove the PCM or replace a single chip.

The General Motors PROM Identification manual that OTC used to provide with their Monitor scan tool and Pathfinder software contained more than 362 pages of GM PROM numbers!Įnter the flash reprogrammable EEPROM (Electronically Erasable Program Read Only Memory) chip. We are talking thousands of different PROMS. Every field fix or recall for an emissions or driveability problem created more part numbers to keep track of. Performance enthusiasts also liked replaceable PROMs because the chip could be replaced with one that provided more spark advance, fuel enrichment, a higher rev limit, etc., to squeeze more power out of the engine.īut replaceable PROMS had a serious drawback: there were too many of them! Every model year and every running change meant another PROM had to be created. It also meant that if a bug was later discovered in the original factory programming, it could be corrected in the field by simply replacing the original PROM with an updated corrected PROM (a tactic GM has successfully used over the years to fix many factory flaws). A replaceable PROM chip also meant the PCM could be “retuned” if necessary to correct certain kinds of emissions or driveability problems. GM pioneered the replaceable PROM chip as a way of programming PCMs to fit a wide range of GM makes and models. Previously, Program Read Only Memory (PROM) chips held all of the PCMs vital calibration information and operating instructions. The first such application was the 1990 Geo Storm. General Motors estimates that they have released flash updates for as many as 70% of 1995 and newer GM vehicles.įlash reprogrammable PCMs have been used in vehicles since the 1990s. PCM flash reprogramming has become common as vehicle modules get smarter and more complex.

from there, the software is transferred into the vehicle via the DLC connector to update the PCM or other modules.

Once that has been installed on your laptop, you can download and transfer the new PCM or other module programming to the J2534 interface tool or scan tool.
Then you have to download their interface software for your laptop so it can handle the vehicle download. Then you have to go to the vehicle manufacturer’s service information website, pay an access fee and find the correct update for your vehicle. First, you have to have a scan tool or J2534 device that can reprogram your vehicle’s computer. offers thousands of online courses for students and life-long learners, you can also find many free courses as well.Flash reprogramming PCMs is NOT for the feint of heart. There are many online education websites that offer academic courses for a fraction of the cost of traditional colleges and universities, making them ideal for lifelong learners.

What is the best site for free online courses? Students can arrive, learn, engage-all at their own pace in a collaborative environment. With improved resources and reduced teacher workloads, classrooms can shift to co-learning spaces. While e-learning won't replace traditional classrooms, it will change the way we know them today. Online education at the career or vocational level is not only available, it is gaining traction among students who recognize the value of earning their education without sacrificing work, family obligations and more.Ĭan online education replace traditional education? Students who are eager to pursue vocational careers, but don’t have the time to sit in a traditional classroom, can rest assured that their goals are still within reach. Online degrees are relatively new in higher education, and still evolving. Generally, any accredited degree offered by an institution of higher education certified as such within in a major country will be recognized as a valid degree.
