Also when I went through the initial setup the computer never holds the engine cid value at 318. I submit that value to the ecu and back out it changes to 317 everytime.
Mine did similar with my 408. Enter 408 and it would later show 407, so I just entered 409 and now reads 408.
Also had trouble with starting then dying once warmed up. Eventually it started straightening out. Swap to timing controlled and it's back but worse. I just need to find time to call FiTech and troubleshoot.
