Total noob ? NLTS how does it work?

Here's a total noob question?

How does No Lift To Shift work?

Thanks in advance.

Most cars have rev limiters set for different situations. For instance, while the rev limiter in gear may be 7,000 RPM, when in neutral (or anytime the clutch is disengaged), the rev limiter may be at 3,000 RPM. Many automatics have this feature too, although, obviously, it isn't based off of the clutch.

When you're doing high acceleration runs at the track, it is often advantageous to keep the throttle at WOT rather than let up (the turbo stays spooled, and everything is generally quicker). By keeping the throttle floored, as you can imagine, the RPMs will be much higher than the rev limiter will allow. Thus, you are prohibited from using this technique.

An NLTS is something that eliminates, or adjusts, the rev limiter somehow. DSMLink is one method of altering the rev limiter.

How do you shift while WOT?

An NLTS is something that eliminates, or adjusts, the rev limiter somehow..

NLTS adjusts the RPM to a lower baseline by linking to the clutch switch. When the clutch switch engages, the RPM's automatically drop to a set point (i.e. 5500 RPM) and if a shift is missed, the motor won't over rev. EPROM ECU's are also programmable with this feature although it requires a clutch wire modification and a splice into the ECU. In addition to keeping the turbo spooled, this also reduces driveline shock.

In the absence of a working speed sensor or pulse generator, NLTS can also be used as a stutterbox. Pretty nifty eh?

Hope that helps,

Andy

Hope it help....

Q: What is Shift (No-Lift-to-Shift) RPM? What NLTS rpm should I choose?

A: Launch rpm is the rev limit you get when the car is NOT moving, and the clutch is pushed in. Shift rpm is the rev limiter when the car IS moving, and the clutch is pushed in, for "flat-shifting", or "no-lift-to-shift". But, you had better have a GOOD transmission to do just that. The most common, and recommended rpm for the NLTS is 6000 rpm. This seems to set you up nicely for the upshift. AGAIN, please remember though, the car will shift normally if you do NOT hold the gas pedal to the floor, so don't be afraid of this option. You don't even know you have the NLTS or stutterbox if you drive normally. How often do you EVER hold the gas pedal to the floor when you shift or launch? Thats the ONLY time you'll know you have those features.
