DIS module must be from 87 to 93 Cavalier. 94 and up the coils are directly triggered by the ecm/pcm.
Those ecm's will work with either high or low impedance injectors. Make sure you pull the Toyota resistor box out if using peak and hold driver.
Cavalier DIS requires 60 deg reference angle. Be sure to install wheel at angle that matches DIS system or base timing will not be correct.
Quad 4 module might work but system is physically tougher to adapt. No plug wires, everything is bolted under engine cover. I'd stick with Cavalier system. Might have to do something for 1X signal though. Cav module may have one available that isn't usually used.
