    2003 Opel Corsa 1.4i ODBII and Computerbox

    Hi. I have a 2003 Opel (Vauxall) Corsa 14i. I want to link Centrafuse with my computerbox. I took it to a local shop and hooked it up to their pc. It comes up with a Motronic M1.5.4 V2 Computerbox.

    What reader will read this chip and work with centrafuse?. Can i build my own from the information i gathered like with a 327 chip ect.

    Thanx for the help

    I believe the Corsa should be OBD II so yes most likely you can build your own.

    To confirm that it is OBD II see if you can locate the OBD II connector under the dash and list what pins are populated

    According to the Opel documentation I have (Tis-2000) the Motronic M1.5.4 is only used on 2.0 and 2.2 liter engines.
    Do you know the engine code for this engine? Something like X14XE? In which country do you live?
    And how many Oxygen sensors are there in the exhaust? 1?
