Imagine bench flashing as giving your vehicle’s brain—a.k.a. the ECU or TCM—a vacation day outside the truck. It’s unplugged and hooked up to a special setup called a “bench,” which is essentially a cozy nest with a power supply, a harness that mimics the vehicle’s connectors, and a power block that’s the heart of the operation.

This setup ensures a smooth and uninterrupted power flow, keeping the ECU or TCM calm and collected during its refresh session. It’s especially handy for those LB7 and LLY models that tend to get a bit cranky when flashed in the truck.

Bench flashing is like a focused therapy session for your vehicle’s control units. It’s perfect for troubleshooting and diagnostics, and it’s a lifesaver for recovering ECUs or TCMs that have seen better days. 

Choosing to bench flash can be kind on your wallet since it eliminates the need for extra gadgets like Autocals or MVPI2/3s. The trade-off? Your truck takes a little nap until the ECU or TCM returns home. But don’t worry, we’re all about speed here. Bench flashes are zipped out the door the same day or the next business day at the latest.

Need a repair or a deeper diagnosis? That might take up to eight days, but we’re on it, ensuring your truck doesn’t stay off the road for long.

I hope this sheds some light on the bench flashing process and its benefits. Got more questions? We’re just a call, email, or message away, ready to chat and clear up any confusion!
