Best data logging/code reader
This is a bit of a lazy post cos no doubt there is plenty of info in the forum about this, so apologies first of all.
What do you guys rate as the best onboard data logger/code reader that I can use at the track. (335i MT)
I want to be able to read codes and if there are no codes but limp mode, what is causing the limp, so I can then target upgrades to overcome the limp modes.
