Project Paddington got it's long overdue ignition upgrade. The kit included Wasted spark LS2 coil packs, custom LS plug leads, custom mounting bracket, custom reluctor sensor mount, modified dizzy cap including new bearings, new seals inside & out and some extra heavy duty ignition wiring.
Engine sounds more crisp, idles lower, 0.220ms timing drift compared to over 0.9ms prior. Time to go racing!!
