Product Description
Perma-Tune premium ignition control module for BMW 3.0CS and 3.0CSi models from 1971-74. The Premium ignition module features a smooth, matt finish that mimics the patina of the original aluminum die cast part. It provides full control over RPM limit, mechanical advance timing, power output, multi spark function and has many other features that can be programmed using a computer, tablet or smart phone. This module comes preprogrammed for the Porsche six cylinder engine so programming changes are optional. The programmable mechanical advance feature is very handy for restoring a distributor advance curve that has been distorted by worn mechanical parts without having to disassemble and repair the distributor. Refer to the USB/Bluetooth section at the bottom of this page for more complete information about your programming options. The Gen 6 Premium Perma-Tune makes diagnostics easier by providing onboard diagnostics that are automatically displayed by two colored LED function lights. These LED lights assist in diagnosing both the vehicle and the ignition module. The green LED is a status indicator that can flash diagnostic fault codes. The red LED is a strobe light that flashes each time the coils fires in the same manner as a timing light. This LED is especially useful for detecting intermittent engine misfire caused by wiring or distributor problems. The LED function lights are mounted in the harness electrical connector and can only be seen when the module is powered up. There are three self-resetting overload protectors that assist in troubleshooting while protecting your Perma-Tune from damage. The overload protectors are hidden underneath the ignition module so they do not spoil the original look of the part.
