🛠️💻 Dealership ECM vs. Small Shop ECM 🚛 Buying a rebuilt ECM from the dealership usually means nationwide warranty coverage 📄✅ — no matter where you are. The downside? ⏳ Warranty claims can take weeks or even up to 90 days, and you may need to buy another ECM just to keep your truck moving. With a small shop, warranty is handled directly with them 🔧. You’ll typically get a much faster turnaround—often 1–2 days—plus significant cost savings, usually about half the price of the dealership 💰.
