The Image below shows the CPU chip that is mounted on the board of the ECU, This will be a 40 pin chip marked with "HD6802W" on the top. Below I will go over both connection types. On 88-89 models there is a open set of solder pads on the board to make the connection. For 84-87 models you need to solder the wires directly to the CPU Pins in the correct locations.
This attaches 2 different ways depending on model year. Installing the CPU Connector to the ECU boardĪt this time you need to add the connector for the CPU connection. Align the number 1 pin with the number 1 pin on the board and press into the holes left from de-soldering the ROM chip.
Now that the ROM chip(s) are removed you can install the socket for the NISTUNE board.
The PDF Instructions linked below will explain this process in detail The process is the same for each ECU but the location and number of EPROM chips will vary by model. To do this you will need to heat each pin of the PROM chip and wick away or use a De-soldering iron or Sucker to remove the hot liquid solder. Now you can start the work of removing the EPROM chips that hold the Fuel and timing maps. Next you will need to clean everything that you will be soldering/un-soldering with acetone as the factory covers everything in a lacquer to protect it from the elements.
If that is not enough then we offer a full insurance backed mechanical breakdown warranty underwritten by AVIVA and a full 14 day money back guarantee.I installed my own NISTUNE board into my ecu myself and it wasn't that hard to do with basic soldering knowledge.įirst start by removing the 4 screws on both the front and back cover of the ECU being careful as they can strip the heads if the ECU was exposed to the elements.
