Timing Tuner
The timing tuner connects inline with the crank position sensor. When the nitrous is activated, the timing tuner can shift the signal to retard the timing. It also has a window switch and activation delay builtin. All of the setting are customizable.

So, if I went and added a 150hp nitrous system to my car and just went to have it dyno tuned............how would that be any better or worse than having a timing tuner?
Its advantage I believe, is you can run a NA Tune and have the timing computer pull timing only when the Nitrous is activated.

The Timing Tuner is a device that is installed on LS1 and derivative engine equipped vehicles for adjusting the spark advance ‘timing’ to extract improved engine performance. The unit installs ‘in-line’ with the crankshaft sensor wiring and alters the signal that is received by the PCM (Powertrain Control Module, ‘engine computer’). By shifting the crankshaft signal ahead or behind in time the spark timing in the engine is changed.
The Timing Tuner is used to adjust the Spark Advance to improve engine response and power. Assuming sufficient octane fuel is used, most production engines will make more power with a few more degrees of spark advance. However when Nitrous Oxide or superchargers/turbochargers are used to raise horsepower the spark advance must be reduced (retarded) to prevent detonation. Detonation (pinging, spark knocking) is very destructive and is to be avoided. Always run high enough octane fuel for the power levels desired.
The Timing Tuner also has a Nitrous Oxide (N2O) control feature. The unit features activation delay, timing retard, and activation controls based on RPM. The setup can be optimized for non-N2O driving and when the trigger wire is energized the secondary settings are activated. This ensures the optimum setting is always available both with and without N2O.
My RWTD NA tune was 308 HP, when I changed my tune for Nitrous (pulled timing) I went to 299 HP NA.

I "PLAN" on only using the spray for track visits....

Do you think it would be that benificial though?
I mean when your talking about 5-10hp for a $300+ item.......that doesn't make much sense to me. If it is a big deal for you to win the race I would think you would use the bottle.
But if its going to take 30-35hp from my car N/A, well I might want to consider it. You know what I mean?

Verdad Gallardo Yep I agree, I am content running with the tune I got. I can swap between the NA tune and the Nitrous Tune with the Predator, but the 8 or 10 HP difference I cannot feel the difference (nor can the wife when she is driving it when I am gone). I don't race often anyway.
Unless you have an aftermarket tune? no timing pull is needed on 150 and below. Just use the highest octane fuel. Also, to be ultra safe, should log for knock retard. Some just randomly pull timing based on the guesstimation rule of XX timing pulled for each XXhp added. I think this is a lame way to do it, but some have no other way, or don't desire to do it by checking if needed.

And I should be making mid 500's to the wheels and around 600rwtq.... You don't think I need a tune for that?
I have one, the main reason I got it was B/C I couldnt get RWTD to modify my tune and so I have a lot more freedom to adjust my timing however I'd want. I also liked the fact that the timing only gets yanked when the WOT switch gets triped.

Here's another myth. Many believe that you run as much timing as you can untill kr appears then back off a couple degrees for best power. This is not true. Max power does not always equal max timing. The best way to set timing for max power is on a dyno and go for max hp, not max timing.

What is actually happening is the crank signal is intercepted and the ECU is tricked into getting that signal measured milliseconds later than it would when the spark advance control is off. Of course this doesn't happen until the Timing Tuner gets a signal voltage to do it. Please correct me if I'm wrong about this.

Another benefit of the TT other than its features of a window switch built in, delay activation of N2O for better hole shots and increased HP off the bottle but that it can help with fuel economy as well since the spark can be advanced and a more complet burn take place which in turn creates more power.
