FiTech EFI system

Thanks for the input guys. The issue always points back to the ecu. Dropping the IAC to below 10 has helped the hot starts. Got the Coronet started last night - had to do a system recal - second time I've had to blow out the cal and re-input. Using the Tach function. Upside is that I can do the entire process in less than 10 minutes.
All connections are crimped, soldered, and shrink wrapped. Not getting any ign fault codes.
I'm seeing now that these EFI systems need to be fine tuned to dial them in. And I'm OK with that, I just wish the manufacturers were more forthright in their marketing campaigns because I bought in to the plug-n-play ads.
This thread has been a huge help and seeing the success members like SalC have had on their installs keeps me going.
