- Ground the Gray tach output wire.
- Turn on power to the ignition without cranking the engine.
- Hold the Gray tach output wire to ground for seven seconds. (AT LEAST five seconds.)
- Release the wire from ground before ten seconds have passed.
- To confirm the process has worked, cycle the ignition power off and back on.
How do I turn off MSD rev limiter?
How do I know if my MSD box is bad?
The best way to check the box is to turn on the ign, then ground – unground the white wire. The box should fire the coil with 400V each time you remove the white wire from ground. If you remove the coil wire from the dizzy and place it near ground, a spark should jump and you will hear high frequency chirp.
What is a 2 step exhaust?
Two step is simply a secondary rev-limiter. Under a certain speed or when a switch is turned on, or a combination of both, ignition or fuel is cut at a certain RPM. This holds the engine at that set RPM, which is ideally the best RPM to launch the car at. Two step can be used on naturally aspirated and boosted engines.
What is a 2-step rev limiter used for?
A 2 step rev limiter is a great thing for those with a manual transmission that want to improve there launching with the car. Anytime you can decrease the number of variables to something, you will gain consistency. Consistency is very important when trying to get a high power car out of “the hole” in drag racing.
Does 2 step build boost on the line?
While 2step does build boost on the line, it is different from anti-lag. How does the limiter work? A rev limiter works by either retarding the timingor cutting the fuel to the motors cylinders. Most tuners will refer to rev limiters in two ways. One is called a “soft cut” rev limiter and a “hard cut” rev limiter.
Why does my car backfire when I engage the 2 Step limiter?
This is why when you engage the 2step rev limiter on a boosted car it becomes EXTREMLY LOUD and you hear all of the back firing. Backfiring is when a car doesn’t burn all of its fuel in the combustion process, and then combusts in the exhaust system.
How do you set the rev limiter on a car motor?
Pick an RPM where you believe your motor makes peak torque. Next set the fuel cut and ignition cut to be the same RPM. Then set the VSS speed to be the speed that you want this rev limiter to stop limiting the motor and let the car rev all the way up.
