LEXUS IS200 FUEL CUT DEFENDER (BLACK BOX)

Used when supercharging or turbocharging the GXE10 Lexus IS200/Altezza AS200 1G-FE engine.

• Prevents the OEM ECUs fuel cut fail safe mode triggered at 129 kPa of absolute manifold pressure.
• Referred by some as a "black box"
• Captures and limits the MAP sensor signal to 126-127 kPa
• Prevents fuel cut on the 1G-FE engine
• May be used on other engines by readjusting the fuel cut threshold via the potentiometer inside the unit (voids the warranty). It's pre-set for the 1G-FE engine.

While sacrificing the MAP correction at boost levels above ~0.3 bar, it's proven that this specific ECU has enough other algorithms and strategies to fuel properly on boost even with the map signal limited (closed loop fueling, closed loop timing, Alpha-N mapping).
