Vauxhall Zafira 1.6i Stage 1 Remap
On Vauxhall Zafira 1.6i naturally aspirated engines a Stage 1 remap refines the ignition timing, fuelling and throttle response maps. Without a turbo the power gain is smaller than on turbocharged engines; the difference is felt mostly in throttle response and the mid-range. No hardware is changed and the original software is backed up.
It depends on the generation and the stock output. 1.6i engines with 105–115 bhp reach 115–125 bhp with a Stage 1 remap; the largest gain is +10 bhp (B 1.6i 16v 105hp). Pick your version in the table below.
