Default No pedal response LFX conversion

Hello,
I posted this in the conversion section as well. Moderator please post where you see fit. Thanks.

I have 2 RX8 LFX conversions in the shop right now and they are both all but done except the gas pedal does nada. Squat. Zilch. Both cars are using an E39 PCM with a base tune from a 2014 Camaro. Throttle body, wire harness and PCM are all sourced from the same year and model.

Both cars start and idle. I have bled the cooling system and I can plug in and monitor with both a scan tool and have downloaded the base tune with HP Tuners. So far I have done the pedal relearn procedure and tried different pedals. I have pinned out all six pins from the blue connector on the pcm to A-F on the pedal. Everything is in order. Also checked pin continuity to the throttle body. All is as it should be. I can't find anything in the HP file that would enable or disable pedal operation but I'm not really fluent with the E39. It has a lot of differences from earlier processors.

I'm getting a crank relearn code but that shouldn't keep pedal from responding. I base that on a few others I've done.

Thanks in advance for any help.
