Enable Clone² NLTS (No Lift To Shift) Control

The Clone² ECU (and almost ALL flash ECUs) can support NLTS (No Lift To Shift) using Chrome v2.0 or higher.

So what exactly is NLTS?  NLTS is a feature which allows you to maintain WOT (Wide Open Throttle) while shifting gears on a manual transmission car.  The Clone² ECU will control the throttle amount for you as you push in the clutch so that you don’t have to “blip” the throttle.  Some people swear it really improves their shifting speed.

In order to implement NLTS, we use the Clone² ECUs built in Park / Neutral ground input (which is always grounded on a manual transmission car) and rewire it into one of the clutch switches used for cruise control.  This way the Clone² ECU will know when the clutch is pressed in.

Fortunately, wiring this in is actually easier than it sounds, although it will require a bit of flexibility on your part!

Step 1

Enable the NLTS feature in Chrome v2.0 and download the ROM to your Clone² ECU.

Step 2

Locate the cruise control clutch pedal position switch located at the top of the clutch pedal.  There are two switches on the clutch pedal.  The other switch is the clutch pedal interlock switch which is used for the starter interlock.  The clutch pedal position switch has a large nut on it and it is also used to adjust the clutch pedal height.

Step 3

Locate the connector that attaches to the cruise control clutch pedal position switch.  There will be two wires in the connector.  A Black wire (ground) and a Black with Yellow stripe wire.  Locate the Black with Yellow stripe wire in Pin 2 of the connector.

Step 4

Using a suitable length of Automotive TXL or Automotive GP wire, TAP into the Black with Yellow strip wire approximately 2 in from the plug.  If you cut the wire and do not reconnect it, your cruise control will NOT shut off when you depress the clutch pedal which could result in loss of life or your motor.  Wrap the connection with electrical tape if you did not use an IDC tapping connector.

Step 5

Route this wire from the cruise control clutch pedal switch to the Clone² ECU location.  Be careful to avoid all pinch points and sharp metal edges so as to not cut the wire.

Step 6

Locate the Park / Neutral wire.  There are three different methods depending on your particular setup.  You can locate and cut the wire in your OEM harness or if you have a Plug n’ Play harness you can locate and cut the wire in the Plug n’ Play harness.

1G (1991-1993)

Locate the Black (Sometimes Black with Silver stripe) wire in Pin 71 of connector C-53 of the factory harness going to the OEM ECU plugs.

2G (1994 – 1997)

Locate the Black (Sometimes Black with Silver stripe) wire in Pin 91 of Connector C-54 of the factory harness going to the OEM ECU plugs.

3G (1998-1999) OR Plug n’ Play Harness

Locate the Black  wire in Pin 67 of Connector B of the factory harness going to the OEM ECU plugs or of the Plug n’ Play harness going to the Clone² ECU plugs.

Step 7

Cut the Park / Neutral wire located in Step 6 approximately 4″ from the ECU plug.  Connect the wire coming from the cruise control clutch pedal switch which was run in Step 4 and Step 5 to the free end that is going TO the ECU Plug using a suitable connector like a Molex InsulKrimp butt connector.  Tape off the remaining free end of the cut Park / Neutral wire.

Step 8

Test the operation of the NLTS by driving the vehicle at a low speed, and while coasting in neutral AND the clutch pushed IN (down), push the accelerator pedal all the way to the floor.  The RPMs should only climb to the pre-set limit of 5000 RPM, or the limit you specified in Step 1.  Also, while at low speed, verify that when the cruise control is activated, that it de-activates automatically when you push in the clutch.

You now have NLTS (No Lift To Shift) working!
