Then, I think just a level conversion to the PCM would be required. The rumour is that EFI Connection attempted this and it just didn't work right.
I've also read of attempts to use the Opti signals and convert them to the 1X and 24X signal patterns the '411 PCM needs.
But, I have never found any cases of running, driving, fully working success when attempting any of these.
