NO CRIMPS, NO MESS, NO HEADACHES
Plug and play features eliminate the need for wire crimps and complicated wiring diagrams. Wires are cut and stripped, then inserted into the wire bus for a secure, plug in connection without the need for special tools or wire crimps.
Simple, four wire installation. There is no need to interpret complicated wiring diagrams, the terminals are clearly marked so you know exactly where each wire goes.
NO DIALS, NO SWITCHES, NO PROBLEMS
Installation is easy. There are no dials to turn, no switches to set and no chips to plug in. The MB3906 Perma-Tune comes to you pre programmed and ready to be installed on your Mercedes Benz 8 cylinder engine. You can always customize the module later using your wireless device to make secure, reliable configuration changes through the built in Bluetooth connection. You can program in the advance curve so that the distributor mechanical advance mechanism can be locked and add multiple strike ignition to aid starting or increase the power output to reduce spark plug fouling. All using free software downloaded from the internet. Don’t want to do any programming? No problem. Programming services are available by sending your Perma-Tune to the factory or have the program customized for you remotely by a factory technician using your computer.
STRONG, YET FORGIVING
