Martin Whitmarsh believes McLaren will be more competitive in China after identifying some solutions to their MP4-28's issues.
McLaren began this season woefully off the pace in Australia where Jenson Button netted two points.
And although the team appeared to have made minor gains in Malaysia, it was again just a two-pointer, this time for Sergio Perez.
After the back-to-back races, McLaren returned to Woking where Whitmarsh believes they have found a better understanding of their car which he hopes will yield massive gains this weekend in China.
"Clearly, our performance in Australia and Malaysia fell below the high standards we've come to expect at McLaren," said the McLaren team boss.
"However, the three-week break between rounds two and three has been a useful one for us.
"We have been fully engaged in further developing our understanding of the MP4-28 and are confident of being able to implement a number of changes this weekend that will widen its operating window and, potentially, improve its performance."
