ATS Diesel has designed this Twin Fueler kit to combine the fuel volume and pressure needed to maximize driving experience. The ATS CP3 control box is designed for the LML and will utilize the pulse signal from the factory CP4 and convert that over to work with the CP3. This will allow a smooth rail pressure curve without the need of going into custom tuning tables to control a secondary pump.
The factory CP4 is designed to be a high-pressure pump to increase atomization of the fuel, resulting in a better driving experience on the new LML platform. Unfortunately, this setup lacks the volume compared to previously used CP3 pump, resulting in a limited power band and short cap on power. (866-209-3695/www.atsdiesel.com)
