Hey guys I need some help here. First of my car is a 01 WS6 M6 it puts about 400 to the wheels.

I am probably going to put a NOS on it. I currently do not have a after market tach, but have been considering one with a shift light, or maybe just a light with a 2 stage rev limiter?

I would like a 2 stage rev limiter but I will also need someting that retards timing when I shoot it.

1 Does MSD make something for our cars that will do what I am looking for?

2 Is any one here currently running this setup?

3 Any other ideas on how I can do this?

4 Any other inf you guys can give me would be great.

 

That looks good but does it have a 2 stage rev limiter?

 

Actually no. heh, all of that for me to say that. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Is there a reason for a two stage rev limiter and not just using a progressive controller? What's the difference and benefits? What size shots are you planning on spraying?

Charlie.

 

I think i may be able to help you out.

We have a LS1 timing controller that should work for you. Basiclly it allows you to control your timing NA and have a retard for when you want to spray nitrous.

The following is just copied right out of the instruction sheet, and the following info should answer your questions better than i can. I can email you (or anyone) the full instructions if you would lke to know more.

************************************************
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.

The Timing Tuner has several adjustments:
Spark Base: Adjusts the spark advance/retard at all RPMs
Spark WOT: Adjusts the spark advance at RPMs over 3000
RPM: Adjust the minimum RPM to activate the N2O relay
RTD: Adjusts additional spark retard when N2O is activated
MODE: A series of switches to set the N2O activation delay and maximum RPM

And remember NOS is a Brand <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

The main reason I want the 2 stage is for launching, not really anything to do with the N20 side of things. I can set it to launch at 5800, then at the line you just floor it and it will hold at 5800. After the clutch is out will goto second stage say 6500.

I'll probably spray a 100 shot. I don't know what a progressive controller is.
