Hi In have a b17 with very good compression runnin ngk iridiums, headers ,intake, exhuast, stg3 clutch, fidanza flywheel, short shifterand 55 shot of zex with purge. When I spray its fine for about 3 secs then my cel comes on and I lose a little power . I usaully cut it off right when I see the light come on. Does anyone know what might make my light come on? My timing is also retarded 2 degrees. I just got this system and it hasn’t run right yet. Please let me know. Thanks
Well why don’t you see what cel code you are throwing? :shrug: That will tell you why its coming on.
okay I did my code check I have a code 1 = oxygen sensor , code 12= EGR, and a code 3 map sensor . And I reset my ecu and ran it again with spray and they all came back but only with spray . Otherwise they never show. Any one got any ideas?
did you hook up anything with the hose going to the map sensor? Because it should not be affected by spray at all.
yeah I connected a t into the map sensor vacuum line for intake pressure to the zex nmu.
don’t know what an nmu is, but I’m guessing its a pressure sensor. Assuming you didn’t change anything else when you connected it, then it shouldn’t be affect the map. Its hard to tell what’s going on with the information you posted. Sounds like its going into safe mode for some reason.
The nmu is what zex calls thier nitrous managment unit,the only vacuum type lines on it are to the intake and pressure regulator. The other lines are nitrous in and nitrous out to the intake pipe, this is a dry shot.
I would splice that into a different line. The map signal hose is definately something you don’t want to be messing with. There are plenty of other options. What about the wiring to the nmu? Take a pic of the engine bay, especially by the intake manifold, so we can see how stuff is hooked up.
I fixed it , Thanks for everybody’s help but the nitrous forum on superhondahad the answer :rockon:
what was it?
dont be a dog to those that tried to help you… what was the answer?
-waiting, and waiting… and waiting…
I hate when this happens.
I can’t tell you the amount of times that I was looking for an answer to a prob… and found threads about it… read the entire thread… only to see “I fixed it” with out an explanation as to how.
