Conditional How-To: Drivable Launch control and NLS!

More fun stuff for my beta guys....

Earlier versions of Launch control and No Lift Shift worked in drag racing situations but were annoying during normal daily driving situations when the fuel cut would be triggered every time your foot brushed upon the clutch pedal. This is no longer the case with the new conditional features. Now we can set up two indpendant tables, one for Launch Control and one for NLS. And we can set up each with suitable conditionals to retain daily drivability without sacrificing functionality. Here's how we do it:

First up, Launch Control.


Before it was activated any time the cluch was depressed. This was unfortunate because launch control was only needed during the launch and no where else. To fix this, we set-up a conditional requiring the clutch to be pressed for more than 3 seconds before the launch control map was made active. So this means that the user simply rolls up to the starting line, presses the cluch for 3 seconds, revs up the motor (bang bang bang), builds boost and whooosh... takes off. The table for launch control can look something like this...



Now, right-click on the table and select "Edit this map." It should look like this depending on how your maps are configured.



As for the conditionals, it is set up like this:




And now.... No Lift Shift


As with launch control, we use our new conditional parameters to make NLS less intrusive. In this case, we only active the clutch-induced fuel cut IF the car is running under high load/boost. This means that under normal driving (lifting off the gas between shifts), the fuel cut is not triggered. This makes the whole NLS system completely invisible until it is called for by simply not lifting off the gas when the clutch goes it. It works ridiculously well. The NLS map can look something like this:



With the following map configurations:



As for the conditionals, set them up like this:



Give it a shot... What you'll probably find is that you can keep both NLS and Launch control in your daily driving map. Along with the full SMART system, this map will end up using 7 tables. That only leaves 5 tables available for your secondary map bank. This just happens to be needed amount of tables for a basic SMART map

Also attached is a complete map for a car that I tuned today (Stg 1+ with methanol). It has a fully active launch and NLS map with a full SMART system. To see what is going one, you can follow the logic on the fuel side (Fuel->Smart fuel->Launch->NLS).

Cheers,
Shiv

Can I add LC/NLS by creating a map 6/7 in an existing xm3 file or do I need to copy the Fuel/Timing parameters into the blank template found in the secret directory?

It seems like you could also only activate NLS if the TPS reads 100... There might be a flaw with that, but it seems practical for daily driving, but again, I'm not a drag racer.

As usual I stumble on this thread by accident and it's something I could really use. Shiv, can you please make the images available again. I also agree, this should be made a sticky.
