Hi, we are PnPduino, makers of Plug and Play Standalone ECU based on the speeduino firmware. We just finished our ECU for 98-02 Landcruiser LC100 /LX450 with a 4.5L Inline 6 1FZFE. This is 100% Plug and Play with stock ECU and engine harness. Basemap is included (Dyno tuned) and it will run the engine better than OEM. This ECU is best when putting a turbo.
