I am having troubles connecting to a 16149396 $DF '93 3400 TDC/DOHC ECM. TP goes into a flashing red/blue on the connect status box

I am using the .ADX from the forum. http://www.gearhead-efi.com/Fuel-Inj...Information-DF I have also tried other versions of the 9396 .ADX files. The forum version goes red/blue. The other versions just stay 'connecting'.

I tried this on a 16149396 ECM from a '91 3.1 and got the same results.

In looking at troubleshooting this I tried on Real Term sending in hex

F4 57 01 00 B4
