data logging with ex2 ,finally got it working,i think.at idle in neutral i need 20 seconds of idle and then increase it slowly to 5000 rpms in 20 seconds.when i start a yellow line starts across the screen and the numbers in the differarnt things i am logging start moving.the line is straight all the time,is this right?do the numbers that keep changing tell the tuner what he needs to know?when the car is moving i assume the graph is differrant or am i doing something wrong?hey,i fell good just getting this far.thanks
