Topic: Opinions wanted: FAST / Speeduino FI or Demon 650
Looking for opinions on which direction to go here. The car is the Horses Ass Racing 1985 Mustang. Ridiculed in the 2019 Gingerman wrap up video as a "systematic failure." (3:07 min in) We ran again this year on a carb borrowed off of my Dad's '46 Plymouth, this time an Edlebrock 600 CFM. I have a FASt TBI and a Speeduino ECU that I need to finish the wiring harness for. Do i try this or just buy a Demon 650 that I can get NIB for $400? The rest of the fuel system can run either, it was originally set up to run the complete FAST EZ EFI 1.0 .
