Clearly you don't need the jaycar.

My questions are:
1. what is the bandwidth requirements for MAP/MAF and O2 sensors?
2. how many channels are really needed? On some cars we have 4 O2 sensors. MAF or MAP are 2 other analog signals. That would bring the number of required DAC to 6. Is this all (note, there aren't microcontrollers with 6 D/A channels, probably we need to use PWMs or something like that).
