The L61 never had variable valve timing, that was the 09-up LAP... It was 2.2 liters, but had VVT and other stuff from the LE5...
However, in 07 they got coil on plug ignition, and a different reluctor wheel on the crank...
Keep in mind that my UG is still reporting around 10% optimistic... I never bothered recalibrating it, because of the time it would take to zero its odometer...
