TACHTIME Data Logger unit by ForeFrontt Technology - Duluth GA. If you are running one of these here is a chance to get a spare unit cheap. Includes main unit, 4-pipe EGT interface, wiring, etc. If you don't have any type of on-board system here is a chance to get the basics without spending much money.
Best Offer by Sept 5 or "buy it now for $100, plus shipping"
