We have a 100% Plug and Play Standalone ECU for 1FZFE Gen 2 (3 plugs 64 pins) with basemap that has been Dyno tuned. Check out pnpduino.com for videos and pictures
hi sorry for the late reply. Yes you will replace the whole ECU and use the same key. the ECU is for 98-02 4.5L 1FZFE Gen2. We also have another ECU for the 93-97 1FZFE that we call Gen3. Both ECUs look the same but the pinouts are different
