wow there is a lot of yummy data in that plot !!!
nice to see the output of the o² sensor is basically digital
that the throttle is really not spending any time in between closed and full open
you can even tell how good you shift was if there was a wheel speed sensor and knowing the transmission gear ratios
also you can tell how much boost lags behind rpm and throttle and how sharp your BOV response is
also it looks like your EGT is measuring more the exhaust pipe temperature than the exhaust gas temperature because that curve shows a lot of inertia !
I'd love to see a 20 minute drive downtown & highway video with this data superimposed, we could learn a lot about the car performance and driver's hability
hey also I think this project could be a very good general purpose data acquisition platform
something like this discussion was talking about http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1196965541/87#87
can you tell me more about this bosch ECU ? is it an OEM ECU made by bosch ? or a special aftermarket one made by bosch ?
do you have information about injector and spark timing and duration that could be superimposed on the data you just posted ?
