I am having trouble getting my FiTech up and running. Ford small block, FiTech EFI, MSD 6. The handheld is working but when I go to initial setup I get "ECU no response". I have a separate wire direct to battery for the +12 volts, the white wire (key) has +12 volts in the on and start position, also tried a separate ground wire from battery to throttle body. The shop that built the motor dyno'd with the FiTech so I am thinking it must be something I have done or not done. Any suggestions?
Do you have the key turned on? You want to turn it on as if to start. Now the unit has power and can talk to the computer.

what bishop said. If that's now the fix, call FiTech.
Sometimes the handheld in our car needs unplugged from the EFI to restore communication. Give that a try before you go too far.
Thanks for the help. Got my car running. It was running rich so I adjusted the IAC steps (drivers side screw) down to approx 6, still running rich. I noticed that there are two idle adjustment screws, one on the drivers side and one on the passenger side. Do I have to adjust both?
Look at your ecu settings before you start messing with the efi. Again, maybe call FiTech.
