Zipper versus OEM ECU
The Zipper unit has many more cells of tunability than the Stock ECU has. It also runs in Closed loop so anytime something changes on the system (gasoline quality, dirty injectors, bike modifications, etc...) the system adapts.
Using a DTT Scan and tuning your bike manually with a SERT or PC is only good for that moment and I bet will not cover all driving conditions. Also, I am basically lazy, I just want to ride! A dyno tune is great if you can find a good one and welling to pay what it takes...6 to 8 hours of detailed tuning.
With the Zipper, you set the target AFR, either total across all RPM's or target different AFR for different TPS and RPM and the system does the rest. Right now, my unit is set for one AFR across the rpm range, this should provide the best fuel economy. Later, I will change different TPS and RPMs to make it for more performance. Either way, I bet it is better than what my local tuners can do.
