Having record a double DNF in Melbourne, Romain Grosjean admits Lotus won't be "100 per cent" in Malaysia but that getting angry won't help.
It was a frustrating start to the Championship for the Frenchman and his team as they struggled to put in the laps.
Issues with their E22 and its Renault engine, meant it wasn't until Sunday's grand prix that Grosjean and his team-mate Pastor Maldonado amassed more than 20 laps in a single run.
While Grosjean covered 45 before he retired, Maldonado managed 29. That, though, was a marked improvement for the Enstone team which Grosjean is hoping they can continue this weekend at the Sepang circuit.
"I think we've made quite a lot of changes and [there's] a lot of areas where we've seen we can improve from the race data we learnt on Sunday," he told Sky Sports. "So hopefully we did our homework.
"I don't think everything is going to be 100 per cent but if it can be a good step forward then that would be nice."
He added: "You have tough weekends in your life. Last year, for example, in Monaco I was super-quick but super-quick in the wall as well.
"Melbourne was a different weekend, in that you get there and know you haven't done enough mileage in testing and don't know where you're going to be.
"If you're extremely, extremely lucky things go right. But basically that wasn't the case."
The 27-year-old was asked about the moment he appeared to lose it during third practice for the Australian GP.
"I was shaking my head," he explained. "I had to take pills after for a migraine, it was really bad.
"Being angry would be the best thing to get your mind out of the right place."
