The term ACE loan is not a USAFA acronym so that might be why no one is answering. I think the ACE (Advance for Clothing and Equipment) loan is for USNA.
The answer to your question is no, paying it early will not increase your paycheck. You will get the same net pay as everyone else and if the loan is payed early, the extra goes into a “held pay” account that you would get when the normal loan pay off time arrives. My son had this due to an outside scholarship that was applied to his loan each semester. He didn’t see the money until everyone else did.
