NIStune Type 1 Hardware Installation Page 11 of 11
The below picture shows the removed ICs, installed 28 pin machine drilled socket and four wire link
jumpers installed in their new locations.
Next remove R15 which is below J9/J10. This is no longer used with the NIStune board installed. Note that
You will no longer be able to use the factory ROM chip in this ECU once these jumpers are changed.
Installation of the NIStune board now follows the same procedure as for other 6802 based ECUs.
