Now, EvoHT2 supports 2018 Ram 1500 5.7L Hemis (8-speed only). This support is accomplished with the tried and tested PCM swap program that Edge developed with ease and simplicity in mind. Edge has found a quick and easy solution that makes tuning these difficult trucks a breeze as Edge takes care of everything. Check out the details on the PCM swap options below and get your late model Ram 1500 5.7L tuned and running Edge Equipped! PCM Swap Options are Option 1: Cross-ship PCM swap (subject to availability of PCMs) after you receive your 36041-S EvoHT2, get your vehicle VIN, calibration ID, and your product in hand and go to www.edgeproducts.com/PCM-SHIP. Once you proceed, you will need to set up a PCM shipment and the included pre-authorization to secure that shipment. This process is all online and very simple. After setting up this process, you will receive an unlocked PCM that is pre-programmed with all of your vehicle details so you can swap it with your current PCM in minutes. This process is 100% free as long as you return your stock PCM as part of the swap process. Option 2: Send in your factory PCM to be unlocked. This free service will be available to you anytime. Please contact technical support to begin. Once we receive your stock PCM, we will quickly unlock it and get it back to you so you can tune with your EvoHT2. This typically takes 2-3 business days to turnaround once we receive your PCM.
