Reflash your TSX engine computer.
This is for an ECU reflash - the ECU is not included. Hondata does not sell direct - the reflash must be purchased from a Hondata dealer. The ECU reflash form must be sent with your ECU.
This reflash will work very well with an TSX in stock form, or with headers and intake.
How do I remove my ECU and immobilizer?
The ECU is located behind plastic panels to the right of the driver's right foot and the left of the passenger's left foot. Both panels will need to be removed. You will need a Philips screwdriver and 10mm socket. Complete removal instructions are to be found on this page. Alternatively you may download and print out the TSX ECU removal pdf file (300k).
