Ecclestone was critical of the new engine formula long before the first 1.6 litre 'power unit' was fired up, but his latest comments follow Melbourne race organisers' claim the low volume may even be a breach of contract.
"It's not what we paid for. It's going to change," Australian Grand Prix chairman Ron Walker told Melbourne's Age newspaper.
Walker said he has spoken to his friend Ecclestone already, while Ecclestone admitted he has been on the phone to FIA president Jean Todt.
"What I've said is that we need to see whether there is some way of making them sound like racing cars," the 83-year-old Briton told the Telegraph.
"I don't know whether it's possible but we should investigate.
"I think let's get the first few races out of the way and then maybe look to do something. We can't wait all season. It could be too late by then," said Ecclestone.
