motoscope are rubbish.

had my YB powered car on his rollers recently and he didnt have any working det cans. then he said he did have some, but the engine was too noisy and he wouldn't be able to hear det anyway. because he couldn't listen for det he simply set all timing at 5 degrees AFTER tdc when on boost. when he had finished he recommended that i fit det sensors.

complete waste of time and money.
