I have some wiring issues with my current nitrous setup but I can't tell whats causing it. It works pretty well but it seems to cut out sometimes. I have it wired up like in the schematic that I have attached. I am using a HSW Interface to pull timing and a Zex Window switch. The problem I see when I datalog is that the IAT temperature does not stay at 158 like I have the HSW Interface setup to do. The IAT temp in the datalog run dips from 158 down into the 130's and then jumps back up to 158. I have tested the Arming switch, the FPSS, the WOT switch, and the Zex window switch and they all tested fine. The problem has got to be related to the HSW Interface. Is the way I have it setup the way it is suppose to be or should it be different? Thanks in advance.

 

how do you have the interface wired to the iat. sodder? or some type of connector

 

I sliced back the sheathing on the wire and soldered the connection and then put heat shrink around it. All my connections are soldered and heat shrunk.

 

try it with out the FPSS

 

Sorry I forgot to mention, I actually have the FPSS jumpered right now so I know for sure its not the issue. Thats what I thought the problem was initially but even with it jumpered it still cuts out. Its not real bad, on the nitrous pass in my sig it cut out one time but since the temperature dips down to 130 its not pulling timing all the time which has be a little worried plus I just don't understand why its not working like it should.

 

Jump over to the support ticket so you can attach all your log files and we'll take a look.

double check grounds. try not to have them all at the same place. check other connections. call hsw
