I'm fairly confident that Motecs line of ECU products all have FPGA's internally. I vaguely remember taking apart an old M400 and it having an FPGA. Thankfully their ECU manager software abstracts that all away from you.
Fair enough. Having an FPGA can certainly make various aspects easier (especially for supporting higher precision outputs), but shouldn't be necessary for basic engine running.
As I understand it, most of the difficulty in modern engines is the tuning anyway. No longer is it just a VE and lambda table, there are so many dimensions that need to be taken into account for a stock car (variable valve timing or lift, electronic throttle control, etc), to get excellent emissions.
