27-year old Dita Pavarniece died when Niall Linden's Lotus Elise crashed into a wall on St Clement's Coast Road last February.
A post mortem concluded a severe head injury was the cause of her death.
In August Linden was put on £10,000 bail.
Today, Crown Advocate Matthew Jowitt said he needed more time to gather evidence from expert witnesses to determine the likely speed of the vehicle at the time of the impact.
Defence Advocate Sarah Fitz asked that her client's bail conditions be relaxed so that he only had to report to the police once, rather than twice, each week. The judge agreed to the request.
He also set a provisional trial date of 24th September 2012, though said he hoped it could proceed sooner.
No plea was entered by Linden today, and there will be a further plea and directions hearing in either late April or early May.
