Description

Stock OEM used ECU from a 2003 Toyota Matrix XRS 6-speed.

This ECU is the best one for swapping a 2ZZ into your 2003-04 Corolla/Matrix because it is designed for the cable operated throttle and it has the higher 8250rpm rev limiter and lower 6200rpm VVL change point. It can be plugged in to your stock 1ZZ harness with the addition of the MWR VVL connector set.

Direct plug in upgrade for 2004 Matrix XRS or 2004 Vibe GT (turns off air injection system, no CEL).

As with all electronic components, returns are not accepted for this item. Exchange or repair only in case of a problem.
