    Once connect to the ECU and with trunerproRT I`ll be able to log boast values

    Been busy playing around with mapping this weekend, discovered I brought the wrong boost sensor it sould be a MPX4250AP not a GP so the ignore the boost and AFR readings.

    Here is the data logging, you will need excel to view it as my copy of excel is unregistered.

    The GP variant should still work, just don't minus 14.7 off it (in Tunerpro settings) as it is calibrated to atmospheric pressure.

    The reading I`m getting from the sensor is in volts and I cant work out how to get tunerpro to convert it to psi.

    It's on the VS thread somewhere, will see if I can find it for you bud. The AP sensor will still give a voltage, but is calibrated in a vacuum.

    Formula for reference is:

    MPX4250AP:
    ((((X/255) + 0.04)/0.004)*0.145) -14.7

    Now I`ve got the boost sensor working it was time to finish of the ECU by fitting the socket for the AFR probe.

    As you can see at full boost the MAF is close to maxing out

    This is why I went for a 3.25" Maf housing

    Whilst sat on a beach on holiday I had a thought,

    Instead of fitting oil temp & pressure gauges why not see if I can get the ECU to log these.

    For the oil temp I`m thinking of fitting a water temp sensor (it uses 2 wires instead of the normal 1) into the drain plug and using the MAP channel in the ECU.

    As for the oil pressure the sensor isn`t a problem but I`m not sure what channel to use but I`ve got a few options.

    I would recommend buying an ostrich. You can write 1 value at a time in the blink of an eye, Doing it through the OBD is a PITA, You have to write a full binary, the voltage has to be correct, you have to go into bootloader. Non of this with the ostrich. I really do recommend it, only about £157 too.

    The only thing that puts me off the ostrich is soldering all the leads to the ECU PCB, I`m waiting to see if the arduino mega is any easier to fit

    Nice, heard good things about that, don't you have to solder loads of wires to the ECU though?

    I'm guessing you can't just unplug the EPROM chip, and plug the Ostrich in though.

    No. the eprom chip is soldered to the PCB, Avintlarge will be removing the chip and installing the ostrich
