AE Tools & Computers 100 Amp Variable Voltage Programming Power Supply

Whether you are reprogramming on board or off board, you must be sure that the power supplied to the module does not drop below proper voltage. Some reprogramming operations with the key-on will turn on cooling fans, fuel pumps, and other components that will cause the battery to drain faster than normal. During reprogramming there is a risk of having the operation fail if voltage falls below the proper operating range. Sometimes a failed operation can be recovered, but there is a chance that failed reprogramming could ruin the control module. To mitigate this risk, and to avoid pulling fuses that prevent battery drainage, put a high quality AE Tools & Computers Programming Power Supply on the vehicle during reprogramming. This Power Supply features adjustable voltage, and a LCD display that shows it’s current settings. 100 Amp, variable voltage unit.
