In this article originally published in Transmission Digest, author Jim Mobley engages in this hypothetical conversation with a shop owner about transmission preprogramming: “I have been paying mobile programmers or remote access programmers (RAPs) far too long. I believe I can save money and time by doing this myself. What type of equipment is needed and what is the cost to get up and running?”

Mobley explains that there are four basic items necessary to start your own reprogramming ventures. You may even have some of these items on hand already.

Windows-based laptop
J2534 interface device
12-Volt 100-amp battery voltage maintainer
Wi-Fi or hot spot

Ignition System Tests You Should (And Shouldn’t) Follow

One of the most basic circuits found on every gasoline-powered vehicle is the ignition coil. This transformer takes low-voltage, high-amperage current and changes it into high-voltage current. It has two windings that are not physically connected. What connects them is magnetism. The primary creates an electromagnetic field when system voltage is applied. When the power is turned off, the magnetic field collapses. The energy from the primary is transformed by the secondary windings into high-voltage power that can jump the gap between the electrodes of the spark plug; this is called inductance.
