Thread: Dry Progressive Nitrous

  1. #1

    Default Dry Progressive Nitrous

    Wondering what experience people have had using the Closed Loop fueling function with a dry progressive nitrous setup. Seems like a fantastic idea to me, want real world feedback from people that have used it. Will be trying it out hopefully in the next couple months (fingers crossed) on my new engine combo (416 LS based deal) with a single stage IS Fogger.

    I've used it, and it works just like the instructions state.

    Thanks Danny. So as long as the rich/lean limits are setup correctly, it should realistically have the fueling dialed in after a few passes. Then I can start walking timing back in it. I was just curious as to how fast it would react to fueling changes at 8000+ RPM.

    Correct, although it's important to have a well tuned Base Fuel & Timing Table, before spraying nitrous oxide.

    Yeah, I'll definitely be making multiple engine passes to get the Base Fuel & Timing Tables all sorted out first. Again, I appreciate the info.

    The dry setup works very well. I used it on a single & double kits. Within the first couple of hits you'll see some lean spikes off the hit that you'll need to adjust for. If using progressive, you'll keep more fuel % then NOS. Set timing very safe and work on fuel. Then start inching up on the timing. I haven't worked with the curves for timing yet, but I'm looking forward to that.

    Yes it does.

    Yes, be sure to tune the "Dry Fuel Delay" parameter.
