Do I need a Map Censor? an EFIE in my car? Can I just hook up the HHO module with the PWM and be good to go?
Please let me know,
Thank you

yes you do need a map sensor enhancer and an 02 enhancer at least. obd 1 cars still have 02 feedback like newer cars the main difference is obd 2 vehicles go into closed loop a lot faster, they can control the fuel/ air ratio at lot more accurately, and they can detect when a sensor is starting to fail but hasn't completely failed. obd 1 only can tell if the circuit is open or shorted.

Could I get away with just the Map Enhancer and leave the O2 alone? Or would you buy something jsut to lean the 02? Liek them extensions or whatever.

if you were to only get one i would get 02 enhancer. but to get the most from it you need to tweak at least one of the input sensors(map, coolant temp, air temp).
