My 1990 civic hatch dx does have a MAF sensor that i am aware of how will a dry nitrous kit work on it??

If you are talking about the one on the firewall attached to the IM via vacuum line that is the MAP, "if you have different TB from 92 up, which you probably don't becuase I don't think you swapped it, then it would be on the TB". You do not have a Mass Air Flow sensor, but you do have a Manifold Absolute Pressure sensor. I believe no adjustment is needed because "I think" the MAP is only concerned with pressure not additives to the system via intake arm, yada yada. Now boost is another story

 

I ment i dont think it has a MAF. I dont understand what is going to tell the ECU to send more gas through the injectors.

What i am saying is that i have a dry nitrous kit. When i spray it i dont understand what is goin to tell the ECU that i sprayed it, and that it needs to add more gas to the engine.

NOS is just a mixture of chemicals that when sprayed into your block makes the explosion under combustion more powerful. Oxygen one of the main ingredients "hints the name NOS" will burn much cleaner and powerful compared to normal air...containing much more crap than pure oxygen. I don't think you need excess fuel when this mixture is shot in because all it is doing is substuting for the air going in. But please someone correct that if it is wrong, because I have no idea about nitrous, only common sense to try and help.

the reason he is asking is because he wants to run richer when spraying because you don't want to lean out when spraying or bad things happen. it is not substuting air it is adding air with the n02 mixture. what you want is either to tune you ecu or get a wideband 02 sensor which everyone who is spraying or boosting should have and get either bigger fuel pump, fuel pressur regulator, larger injectors or a wet kit conversion

 

I have an ajustible fuel regulator. I just dont know what kinda PSI to run. Do u think a 35 shot all stock would hurt anything??

 

i think you will be fine but you will be on the lean side when i had my dx stock i was at 13.4-1 afr but you have the mpfi swap so you should be fine you should get a wideband o2 sensor and adjust from there
