Mitsubishi 3000GT

Having trouble with your 3000GT ECU?

These early nineties Mitsubishi 3000GT ECUs, TCUs and ECS are prone to failure due to the original factory electrolytic capacitors. When they get to a certain age, the capacitors start slowly leaking an oily fluid that eventually will corrode the copper lines of the printed circuit board, as well as degrade or ruin the metals of any components that were saturated in the acidic chemical.

After an ECU has been properly overhauled, the capacitor problem will not be back again. Only the old original factory capacitors, be it from Nichicon, Rubicon or otherwise, are what is causing all the trouble. These capacitors were all made in the 1980s, and later wound up in various Japanese brand electronics and automotive control units in the early to mid 90s. This is not a problem with contemporary components.

Important note:

In some cases, the vertically mounted "sub-board" near the center of the board, either the MH0210 or the E552, is damaged and has to be replaced.

This sub-board is only available from another "donor" 6 cylinder ECM, and that donor ECM will be useless after it is removed. We charge an additional $150 to sacrifice one of our other ECMs to save yours, unless you can provide the donor board yourself.
