EGR Delete Kits

Keep Your Check Engine Light Off — Without the EGR System The EGR Simulator Eliminator Kit is the smart solution for 1986-1995 Ford truck and Mustang owners who want to remove their EGR system without triggering the check engine light. Unlike traditional block-off plates that leave the ECU complaining, this kit electronically simulates the EGR position sensor signal — so your computer thinks everything is working normally. How It Works Plug-and-Play Design — Disconnect the factory EGR valve position sensor connector, plug in the simulator module, secure with a zip tie. Done. Correct Voltage Signal — The module sends the precise voltage range the ECU expects from a functioning EGR valve (typically 0.5V-4.5V sweep). No Tuning Required — Works on stock OBD1 ECUs without custom tuning, flash tools, or chip burning. Works With or Without Physical Delete — Use it to fix a faulty EGR valve without deleting, or combine with a block-off plate for a complete EGR removal.

Feature EGR Simulator (This Product) EGR Delete Kit Physically removes EGR valve ❌ No ✅ Yes Prevents check engine light ✅ Yes (electronics trick) ⚠️ CEL stays on (unless tuned) Installation difficulty 🟢 Easy (15 min) 🟡 Moderate (1-2 hrs) Fixes stuck EGR valve code ✅ Yes (bypasses sensor) ⚠️ Must also tune ECU Reversible ✅ 100% (unplug and go) ✅ (keep old parts) Best for Fixing P0401/P0402 without major work Permanent EGR removal for off-road builds Already removed your EGR system physically? See our F150/Bronco EGR Delete Kit which pairs perfectly with this simulator. Installation: 15 Minutes, No Special Tools Locate the EGR Valve — Passenger side of intake manifold on V8 engines, driver side on 4.9L I6 Disconnect the EGR Position Sensor Connector — The 3-wire electrical plug on top of the EGR valve Plug in the Simulator Module — Connect the simulator to the factory harness connector Secure the Module — Zip-tie to a nearby bracket or harness, away from exhaust heat Start the Engine — Verify no check engine light, test drive to confirm Troubleshooting: If CEL persists after install, check that the connector is fully seated and the module's LED indicator (if equipped) is active. Clear existing codes with an OBD1 code reader or disconnect battery for 15 minutes. Frequently Asked Questions Will this fix my P0401 or P0402 code? Yes — the simulator sends the correct voltage signal the ECU expects from a functioning EGR valve, so it eliminates both insufficient flow (P0401) and excessive flow (P0402) codes on OBD1 Ford EEC-IV systems. Do I still need to remove the EGR valve? No — the simulator can be used with the EGR valve still physically installed. However, combining the simulator with a physical EGR delete (block-off plate) gives the cleanest engine bay and removes the carbon buildup issue permanently. Is this street legal? No. Tampering with emissions control systems is a violation of federal law under the Clean Air Act. This product is sold for off-road and racing use only. Not legal for on-highway vehicles in any U.S. state. Will I pass a smog test with this installed? No. A visual emissions inspection will note the disconnected EGR valve. If your area requires smog testing, keep your original EGR components for reinstallation before testing. Does the simulator work on OBD2 Fords (1996+)? No — OBD2 ECUs use more sophisticated EGR monitoring (including MAP sensor delta and oxygen sensor feedback). This simulator is designed specifically for OBD1 EEC-IV systems (1986-1995). OBD2 trucks require a custom ECU tune to properly disable EGR. ⚠️ OFF-ROAD USE ONLY — This product is intended for closed-course competition, off-road, and racing vehicles only. Not legal for on-highway use.

Physical EGR removal will trigger a check engine light on stock ECU tunes. To keep the CEL off, you have two options: Custom Tune — A dyno or mail-order tune can disable EGR monitoring in the ECU. Recommended for best performance gains. EGR Simulator — For 1986-1995 Ford trucks (OBD1), our EGR Simulator Eliminator Kit plugs directly into the harness and keeps the CEL off without tuning. Frequently Asked Questions Is EGR delete legal for street use? No. Removing emissions equipment is not street legal in any U.S. state. This kit is intended for off-road and closed-course competition use only. Check your local and state regulations before installation. Will I pass emissions testing after EGR delete? No. Your vehicle will fail a visual emissions inspection and may fail an OBD2 plug-in test if EGR codes are present. This modification is for off-road vehicles only. What's the difference between this EGR Delete Kit and the EGR Simulator? The EGR Delete Kit (this product) physically removes the EGR valve and blocks the ports — best for track cars and dedicated off-road builds. The EGR Simulator electrically tricks the ECU into thinking EGR is functioning — ideal for 1986-1995 OBD1 trucks where a tune isn't practical. Does EGR delete add horsepower? On a stock engine, expect 5-10 HP gain from cleaner intake air and reduced intake temps. Gains are more significant on supercharged Terminator Cobras where hot EGR gas compounds heat soak issues. Can I reinstall the EGR system later? Yes — the block-off plates use stock bolt locations. Keep your original EGR valve and tube if you plan to revert to stock. ⚠️ OFF-ROAD USE ONLY — This product is intended for closed-course competition and off-road vehicles. Not legal for on-highway use.
