Dry shot: Solenoid failure: Low TPS
What happens when your nitrous solenoid doesn't shut on a dry shot?
Scenario: You let off of the throttle and your motor starts decelerating and the nitrous is still spraying.
Does the MAF still compensate?
I purchased 2 nitrous solenoids to avoid this situation and it just had me thinking, "what would actually happen?"

well...actually...if you close the TB (let off the gas) there will be nitrous only going through the meter hole on the TB and around the edges of the blade. This will usualy result in the car revving high or maybe even bouncing off the rev limiter if enough is getting through. The rest of the nitrous will come out of the front of the airbox.
As long as you close the TB I dont think the effect will be catastrophic. I belive the MAF would still compensate since the entire intake charge will be nitrous at that point and be much colder than normal...it may even go rich. But thats just speculation since I dont think anyone has had a wideband on when its happened.

I can tell you exactly what will happen. The engine will die immediately.
No damage.

I haven't been scanning when the engine died with the N2O wide open, so I don't know for sure which it is, but it's either way too rich due to the MAF input, or it's way too lean due to the oxygen content.

Well it was both stages, and I really don't remember the jetting at that time 125/150. Everytime I pulled out at a light, or the bank, because I drive hard anyway the rpms would be at 3000 and bam man this is pulling today, then 4200rpm bam it's pulling like a mo fo today. Why I didn't figure it out sooner is behond me. I have rpm activated indicator lights on my dash, so I can see when and what rpm each stage comes on.
