spi trottle pedal switch

[david29dpo]

according to the manual, my early 1996 mini cabriolet should have a trottle switch on the pedal. i guess this is to tell the ECU to cut the fuel off on over run. mine has not gone one and never had one by the look of it. i did hear the later spi minis did not have this but how dos the ECU know when i have took my foot off the pedal?
