ECM Send In Process

This device includes our ‘ECM Send-In’ process, which will require you to remove your trucks factory ECM and ship it to us for unlocking. Once our specialists create the internal ECM modifications, it will be returned to you for re-installation into the truck, where you can then tune with your choice of calibration within the Flashpaq device. The purchase of the Flashpaq 2847-S includes the cost of the ECM Unlock and Next Day Air return shipping of your ECM. Consumers should expect a 24-48hr turn around time, so we do our absolute best to limit your trucks down time to as little as three days. Our ECM modifications are safe, reliable and compatible with GM dealer tools and flashes. So, your local dealer can still interact with your truck after you’ve returned your Flashpaq tuning to factory settings.
