    I dont need to pull my battery or anything just to install a new TMAP sensor, right?

    Im going to upgrade to an N20 3.5bar TMAP sensor. I could have sworn I saw posts indicating sensor installs are real finicky and I need to pull all power before disconnecting or do something unsual lest the computer/tune wont read correctly.

    I cant find the threads now though.

    Is there anything more to installing the sensor then just unplug old and add new?

    I’ve always pulled my motor out when replacing my MAP sensor.
    Which is why my motor has not been in my car in over a year. Click here to enlarge

    ^^ lol cheeky buggers


    found the thread i mentioned - its called “MHD w/ N20 3.5bar help” if you search the other forums

    The tuner in the thread says the ECU must be asleep and your MHD tune must be flashed to the new sensor before removing the old. Easiest way to put to sleep is pulling battery, I guess

    Uncertain if any of that’s needed but my car has given me such fits Im trying to handle even the simplest task with whatever people experienced
