Shooting flames with my Lingenfelter 2 step launch control

I set it at 3,500rpms. Works pretty well...to bad it is too cold or icy to actually launch the car right now.

Just an RPM limiter. Here is the info from the site.

"Sometimes referred to as a 2-step or launch controller, the LNC-2001 adjustable RPM limiter and timing retard controller can be used to provide consistent launch RPM off the line in drag racing and other standing start racing applications. In turbocharged applications the LNC-2001 can also be used to retard the timing in order to build more boost at the line.

The LNC-2001 can also be used as an adjustable individual cylinder RPM limiter, providing reliable and fast acting spark based engine RPM limit control. This is especially useful in vehicles that have auxiliary fuel control systems where it is not possible to make sure that both the factory ECM/PCM and the auxiliary systems both turn off fuel at exactly the same time. If the two don’t completely cut fuel at the same time you will run lean when the one system cuts off the injectors, risking severe engine damage.

Please note - although launch controllers like the LNC-2001 are often referred to as 2-step controllers, they are not true 2-step controllers. A 2-step has a high and a low RPM limit function with a switch of some type enabling one setting or the other. The LNC-2001 only has one RPM limit setting so if you are using the LNC-2001 as a launch control RPM limiter, you will need to use the factory ECM/PCM as the engine maximum RPM limiter engine speed governor.

The RPM limiter function of the LNC-2001 acts by disabling spark to individual cylinders and not fuel like most production RPM limiters so the 2-Step/Launch Control function is not meant for use on the street or for use on cars equipped with catalytic converters. The 2-Step/Launch Control function of the LNC-2001 is only for use at the race track on race vehicles not equipped with catalysts. Failure to follow these precautions can result in premature catalyst failure."

I've had mine sitting in a box for 6 months, after seeing this I might need to finally get around to installing it!

Any chance you might be able to have someone film your belt tensioner while you're on the 2-step? Curious how much that thing is flopping around with all that carnage going on
I doubt anything is really happening but you have sparked my interest to watch.

May not be this violent, but SOMETHING has to be going on. Lemme know what you see if you get a chance to scope it out. After seeing the video above I really hesitated putting mine in. I dunno how much a 109" long belt would appreciate that haha

The car was building 15 psi and shooting meth...I am going to have a shit ton of power off the line. I hope I have traction!
