The HKS VAC Velocity Advanced Computer - Type Z is an electronic device designed to eliminate the vehicle's factory speed limiter. When competing on the drag strip or a circuit track, the factory speed limiter can hinder a vehicle's performance. The VAC is a completely plug-and-play application with not need for modification of wiring/drilling/custom fabrication, and is a must when wanting to go faster than the factory settings will allow.

FEATURES:

- VAC Type Z is a device that cancels speed limiter of FAIRLADY Z for circuit driving.
- CAN BUS signal, which controls whole vehicle systems, will be used for cancellation of speed limiter. Thus, speed limiter is canceled safely and surely.
- Only 4 wires of ECU harness need to be modified to connect VAC Harness. Once VAC Harness is removed, it will be stock control.

Functions:

- Speed limiter cancellation function - Option speed signal output function

Advantages:

- If option vehicle speed analog output wire that outputs converted signal from CAN BUS system, is connected to Circuit Attack Counter, Turbo Timer etc., car speed can be monitored. (Speed pulse 4)
- As it is an external device, even if data of stock ECU is reflashed, functions of VAC Type CM can be used.
- Stock meter shows actual vehicle speed.

Installation:

- Modify 4 wires of ECU harness and connect VAC Harness.
- Connect VAC Harness to VAC Type Z Unit.
- Fix VAC Type Z unit.

Kit Includes:

- VAC Main Unit
- Vehicle Specific Harness

COMPATIBILITY NOTES:

- It cannot be used for vehicles with synchronized downshift rev matching system.
