All the features of the TEL TAC II plus.
Automatically records the best 2 laps from each session.
Displays 4 high rpm readings (straights) & 4 low rpm readings (corner) + overall high reading.
Displays all 9 readings automatically when engine shuts off.
Having the exact rpm range from each session gives you information never available before in a self-contained unit. This info is invaluable for setting proper gear ratios, engine tuning, chassis setup, driver consistency etc. Having 4 extra high rpm readings confirms the true top rpm. The 4 low rpm reading lets you know your actual rpm range, also shows the differences from each corner.
