    Blutooth serial Com in ECU

    Hello .. I open this topic because I have a doubt in the car Honda Accord EX ​​1990, Prying open the ECU, which I found a 5-pin connector, which is finding out on the internet to load a map using a port number of any computer, please correct me if I'm wrong, by that port and an RS232 cable can be chipping the ECU, on ebay selling Bluetooth module which operate between 3V and 5V supply, this module pordefecto predefined as serial com vien, bone mendiante pairing with a PC module that generates a Bluetooth wireless link, my question is this

    - Someone has done this operation?
    - I could use to help monitor the engine sensors in real time and change the parameters in real time???

    I don't know of anyone that has done it... but I don't see why it wouldn't work. If I remember correctly, that is where a datalogger would be connected... so attaching a device that would transmit the data wirelessly via bluetooth, rather than with a wire, would be easy enough.

    It would be a very useful thing, if you can make it work.

      That's actually pretty genius... You would need a virtual USB to run through the Bluetooth to connect though. If you're trying this, then it's highly likely that won't cause a hiccup.

          Looking over the information and pictures provided, that is a p06 ecu. As for whether the that particular bluetooth module will work or not, I cannot say for sure, but I do not see why not.

          The only thing is, that module can only really be used for datalogging, and with software that can communicate with the ecu.

          You will not be able to program/tune the ecu with just that either, now if you had a moates demon, and their bluetooth module, you could do both.

          Otherwise without an 'emulator' your not going to be able to tune 'on the fly', more like park, burn a chip, swap e/eproms, and start again.

            That's like a wireless version of Moates' Hulog.

                You should consult the pgmfi.org wiki/library for the details of the tx and rx pins, and for good review, there's a ton of useful info.
