AT tranny more prone to knocking?

[normality78]

ok, im actually reading this emanage ultimate features stuff and looking to justify to upgrade over from my blue.

thn i spotted this feat called...

"A/T Shift Compensation Feature - On vehicles with Automatic Transmissions, ignition timing can be compensated at set shift-up and shift-down points".

and i remember i saw the abt the samething in HKS Fcon-Is

"Ignition Revision on an AT Vehicle···· Prone to knocking during shifting, this function remaps the ignition curve"

Does anyone know how does it work? Why is it on auto tranny, during shifting more prone to knocking?

only reason i can think of is that since the shift in gears in an AT tranny wont give the engine a slack unlike a MT tranny wherein one has to step on the clutch giving the engine slack.

hmm, maybe..
