my kpro says i need to disable the onboard datalogging before i can do anything with the ecu... also im putting a 75 shot of nitrous on my k20a2 and im trying to retard the ignition timing 2-4 degrees and was curious if that is adjusted by the cam position sensors through the kpro... im new to kseries and the coil on plug end of things....

If it says to disable on -board datalogging to be able to datalog with the laptop then you will need to do that and re-upload your calibration.

You change the timing values in the ignition timing tables.
