Hi all,

Using a Haltech 1500 to control a 2001 Miata (MX-5) 1.8L VVT engine which I have placed into a GBS Zero (lotus 7 replica). Have had engine started but have some ECU issues still to work through. Didn't win the free Haltech but just worked through the EFI fundamentals course and learned a nice assortment of information. Thanks for the work.

What's the deal under the; How ECUs work/ Calculation of cycle time/ at about the 1 minute mark with 3000/2 = 50?? I sorted it out but seems to be a typo.
