For the umpteeth time I dont want to change the code in the ECU... I want to extract data out of the ECU, ie sensor values, load, temperatures, throttle position, vehicle speed, rpm etc.
And as of last night I managed to do it. Im still working on getting a continuous flow of info out of the ecu but hopefully with some more software tweaking that will be int he bag soon.
The data streams coming out of the car ARE NOT encrypted, they must be readable within certain standards.. Do a search on EOBD and see what I mean.

As you can see the car is stationary, at idle (780RPM), and the coolant is still warming up. But you can also see the Intake air temp (45 degrees) is quite high becuase the car had been parked all day in the sun.
This kind of data is very useful for tracking the effect of modifications and seeing how they affect the performance of the car. Ihave used it in the past to compare ECU programming, comapre drivers and cars on closed circut driving (can overlay time data onto a track position map and see how theyre operating throttle etc ....
All very handy
