    I think we all know by now that you can reset your ecu by disconnecting the battery for half an hour. But what happens if you`ve had a remap ? does it go back to original config ? If it does you could lose £500 worth of remap just by having a starter fitted, unless some sort of code saver for example was used. anybody know ?

    I'd *guess* that it shouldn't be affected, as AFAIK a map is coded into the ECU in a similar way to a flash-EEPROM; and as such the memory becomes non-volatile after the writing-process is complete.

    That said though, I remember reading on one of the forums someone had a suspicion of losing a remap after battery disconnection/replacement - I'm not sure how that panned-out though; and whether it ever became a confirmed cause or not.

    Regards,

    Rob.
