Just installed a tripminder computer on my 87 t-bird. Now I finally have an instant FE reading available to me. Plus, it's a ford unit, and it looks quite stock!
Now, if anyone out there has an 80's style ford EFI car, the ones with the EEC-IV comp in them, they can get one of them too. If you have the electronic clock cluster that has the Date/Time/Elapsed Time options on it, you can swap it out for a tripminder that has Time, Trip distance, Speed, Instant FE, Avg. FE, and gallons used. Real nice!
