As cars become more and more complex and ECU reflashing technology becomes more advanced, the gap between sticking with a vehicle’s factory computer and going to an aftermarket standalone only gets narrower and a little less clear. On this episode of Tuned In, we dive into this topic, along with many others, with PCMTec’s Roland Harrison.

Recently though, PCMTec has been moving into the more global Ford market, offering advanced tuning options for Mustang, F150, and Explorer models. It wasn’t always all about cars for Roland though, having spent a good majority of his working life in the oil and gas industry, calibrating and maintaining massive industrial engines and electrical systems. After learning all he could from the business, Roland, along with a business partner, decided to turn his hobby of messing around with reflashing into a business and full-time career. Roland takes us through the whats, whys, and hows of making this transition — even spending some time discussing some of the more surprisingly interesting aspects of his work in oil and gas. With that said, the real meat and potatoes of this conversation come when Roland and host Andre Simon move into the world of reflashing, discussing all aspects of this sometimes very complicated field. There’s a lot to learn here as Roland breaks down the process of creating a reflash solution for Ford’s sometimes extremely complex ECUs, as well as how they’ve added an impressive array of custom functionality to these computers, and more. You’ll also find a great discussion around one of the main differences between most reflash options and standalone ECUs — live tuning, as well as map switching on the fly and plenty more.
