How easy is the tunit to adjust?
The tunit is very easy to adjust. Each tunit has a 9 position dial that is reached by a clear plastic removable cover. The dial will always come set at 5. You may turn the dial up or down to achieve better power or fuel economy. The tunits II, III & IV are adjustable in a similar way but work with a screw with no fixed positions. If you have a specific application you need to adjust for, such as towing or using the tunit in conjunction with further engine modifications, we can alter far more parameters with a laptop tune (available at all our distributors), and tailor the tunit to your preference, i.e. bringing the power in further down the rev range or extending it to higher revs. Please contact a distributor for details.
