Alright so heres the deal guys. Good news is, everything was working fine on my dynotune dry kit, and I went out to start getting it tuned on only a 50 shot with my wideband. everything went well, and i tuned to a rich 11.0-11.5 A/F ratio. hit well, and pulled well. great! i was ready for the track tonight. i started the night off great with a 13.31 @107.4 with a 2.01 60' (Lid and Catback only, 38 degree weather)

the night got shitty real fast. i decided it was time for a nitrous pass.

Bottle Pressure set at 1000ish psi
Purged until I saw "white"
Flipped the arming switch at 3200 RPM, 2nd Gear (a4)

well, it hit "alright" right off the bat, and quickly died out followed by the engine sputtering, and the service engine soon like coming on intermittantly. according to the A/F wideband, it never went lean...which is good. but im confused. Air in the tank maybe? please help guys!

 

first find out what code you though and then pull off your lid and make sure you did not freeze your MAF.

on a small dry shot like that, i wouldn't think air in the bottle would cause those kind of problems. when i used to have my old dry 100shot i got an air packed bottle once. in my case, the car just felt like it was running NA and never bogged or missed.

I have only one question for those who THINK they get an "air fill." How much does air weigh? The simple answer is.... if the bottle weight is correct, it CANNOT be full of air! Air will NOT add weight to an empty bottle.

 

ok so why would it have worked flawlessly earlier that day with no sputtering of SES lights? the light never stayed on, so would there even be a code stored for it?

 

most likely something small.
