Ericsson's retirement and penalty at Sepang was a disappointing end to the first GP2 race weekend of the year, which had started brightly with Jolyon Palmer going fastest in practice on Friday and then qualifying in seventh position for Saturday's feature race.
However, a team decision to opt for two new tyres only during the mandatory pit stop ultimately backfired on their efforts with Palmer dropping to 17th place by the chequered flag, as Jackson admitted afterwards.
"During pit stops we changed only rear tyres on both cars, in the hope that we could jump some of the cars in front," he explained. "This proved to be the wrong decision as we suffered more degradation of the front tyres than expected, which meant that both cars were losing ground, with understeer right through the second phase.
"This was very disappointing after such an encouraging couple of tests, where we felt very confident of our race pace," he added. "However the solution was very obvious, so we know we can fix it!"
