Changing MAF sensor

After looking at various threads and taking live data with a Hawkeye on a Thor engine I have discovered that the MAF is reading low, 14.75 at idle and 62.50 at 3000 rpm off load.
My question is can I reset the adaptive setting with a Hawkeye and how is it done and do I really need to after fitting the new MAF.
Thanks for any information.

Your right, those readings Are low. Not sure about the hawkeye, I've only ever used a faultmate but the Motronic ecu will adapt quickly to the new MAF readings.
