  • Nitrous with ms 2 v3. 57

    Wondering if possible and if so how I would go about setting up my zex kit up to the ms unit for it to essentially operate the on/off switch so that I can use the system during rpm windows at wot instead of just at wot?

    MS 2 v3.57
    Thanks

    Yes - they have some notes on example wiring starting at the bottom of this page: http://www.msextra.com/doc/pdf/html/...e-3.4-162.html

      Greg, your problem is quite simple. I predicted I would see what I'm seeing.

      You are going into fuel cut, or overrun. It's cutting fuel completely when it sees the paramaters you told it to cut fuel at, it gets below your overrun cut-off rpm, then it adds fuel back, so RPM's climb back over your threshold, then it cuts it, over and over.

      You should probably decrease your MAP value for when it cuts fuel. Something well below what your car will want to idle at. it looks like you have it set at like 27kpa. That's way too high. You don't want it cutting fuel when your revs are dropping in neutral, you really just want it to cut fuel completely when decelerating in gear. Mine is in the low 20's IIRC.

        Thanks that's what I was looking for. I'll get a chance to play around with it once I can get my hands back in NY laptop. Stepdaughter has kind of taken it over since starting school so I'm probably have to aquire me a new one lol. Thank you and I'll check back if I have any issues asking the way. I will feel much better running the kit within windows.
