The duo have been running a hybrid machine that combines Aprilia's championship-winning 2014 WSB bike with new a new engine and electronic package for the past two days at the Jerez teasing, ahead of the Sepang tests in February.
Speaking to MCN, Laverty said that the testing they are doing is very different from the norm.
"We've been doing the donkey work on a bit of a parts special bike! Normally you go to testing to try and make the bike go as fast as possible, but we've been doing strange things like purposely running off the track to make sure the sensors can react to it."
"The intention is that next month when we go to Sepang we'll be able to plug the new software into the GP bike's ECU and be able to then concentrate on things like chassis development instead," he added.
