Holley ECU Vs stock ecu

anyone know the advantages of switching to a holley ecu vs keeping the stock ecu and tuning with hp tuners?

Holley ecu should allow you to run a complimentary port injection fuel system and be able to synchronize it with the factory direct injection system, they do more as well.

is this for a swap? the holley will do a lot that the stock ecu can't. but if it's in a 6g chassis id expect to lose basically all other functionality of the car.

Yeah I don't know where people get the idea you can just easily swap to a aftermarket ECM, there is an insane amount of stuff you would never even think of thats needed just for powertrain related stuff.

Thats not even mentioning the 6th gen is global A so even if you got it to start and move you would never get anything else in the car to work again.
