Common Questions?

What is the D1SPEC  Voltage Module and what does it do?

This product is a high capacity voltage stabilizer with advanced chipset designed to regulate voltage in your vehicle like no other. It stores electrical pulses in your vehicle using D1 patented NDDDD X3++ CHIP technology, developed by the Fujitsu factory in Japan. The chipset store the energy and release to your vehicles electrical system when on demand. As you know the alternator and battery are never in sync and never produce the same steady voltage. Heat, speed, electronics and vibration are many factors that can cause voltage fluctuations in your vehicle.

Why did my car not come with this kind of product from factory?

Good question. If this product is so great, why not have it installed by manufactured? The main reason is cost. Every manufacture tries to cut cost of production. Even $50 extra cost to them could be millions in production costs. Most manufactures won't include products like this not only because of cost, but because their vehicles are not performance oriented. A Honda Civic for example is not targeting performance.

Installation instructions - Please read

Step 1: Connect the (+) terminal from the D1SPEC to your (+) terminal on your battery, followed by the (-) to (-) (also known as ground).

Step 2: Mount the product in a location away from too much heat or vibration.

Step 3: Plug the black grounding cable into the D1SPEC, then ground the metal tip into any metal chassis or existing bolt on the frame of the vehicle.

Step 4: Optional Step, use the provided ground cables as you choose: Make additional Grounding points from battery to chassis of the vehicle. Make additional grounding points from alternator to body of vehicle. Basically the more wires grounding the chassis the better the electrical flow.
