get a cable and download the software and you can too!!!!.... but a step at a time, Rob is treading a nice cautious path, that will bare him the fruits he deserves, not sure I'd have has much self control when it comes to tweaking the ecu

Need to get my 4.4 in to tweekable mode first, it still has an immobilizer bin file written to it at the moment :(
This little beauty arrived in the post today :)

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.

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.
PMd you back bud :-)
Formula for reference is:
MPX4250AP:
((((X/255) + 0.04)/0.004)*0.145) -14.7
MPX4250GP:
((((X/255) + 0.04)/0.004)*0.145)
Now I`ve got the boost sensor working it was time to finish of the ECU by fitting the socket for the AFR probe.

Went out for a drive to collect some date :)

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

This is why I went for a 3.25" Maf housing
And here is a bit more data logging :)

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.
cracking work Oblark!
Ordered this tonight link so this will make it alot quicker and easier to flash the ECU
Keep up the good work, seems to be coming along nicely.

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