If your ECU has no daughter board then the USB connector board may face upwards If you are using a daughter board then ensure that the USB adaptor board faces downwards and does not touch any other components Notes A31 RB20 S13 CA 18 It may be necessary to use longer screws to hold the original potentiometer bracket U13 KA24F EK10 MAO9 The bracket has a single screw You will need to fabricate a custom bracket using two screw holes to hold the USB adaptor HR31 RB20 We have found that there is no room for the USB connector You may have to relocate this bracket by drilling and tapping new holes in a different location if you wish to have this fitted permanently Ensure your USB socket 1s installed correctly and pressed against the ECU casing This provides a ground contact point for the USB shield to the board to absorb electrical noise and prevent unwanted USB disconnects during operation NIStune Type 1 Hardware Installation Page 24 of 24 6 Inserting The Board Push the NIStune board into the machine drilled socket previously installed Connect the CPU cable to connector X1 and the USB cable to connector X2 Ensure the PGM jumper is not soldered if the board was previously programmed Where there is a knock sensor board being wary of the knock sensor cable If the JTAG programming pins pointing upwards appear to touch components of the knock sensor board these can be trimmed back with wire cutters as these are only used2. 5 1 volts NIStune Type 1 Hardware Installation Page 29 of 29 e Ar e a UM rn er n o PPP 6 Rewire the AFM as per pinouts in the AFM section of the Nistune Software Users Manual 1987 1989 Z31 1 Disconnect parallel resistors pictured below and and remove resistor R201 A a EE ae ei ATEO z Llu 4 a 3 ban S 2 Rewire the AFM as per pinouts in the AFM section of the Nistune Software Users Manual NIStune Type 1 Hardware Installation Page 30 of 30 1986 1988 HR31 RB20DET Note the later year models such as MEC R70 do not require this modification 1 Locate opamp daughter board a Ud ryg naen wei DDTF mu 7 da i r a wr ar ct a E E E ee A al STE T g Cai a z ci sia Fd F tia em Arta ake erect ee re ees ima dh a ce ETNO 2 On reverse side of ECU count from the outside edge inwards and bridge pins 7 and 8 with solder 3 Connect a 5 1 volt zener diode with stripe side on pin 8 and other end on pin 6 ground as pictured below 4 Rewire the AFM as per pinouts in the AFM section of the Nistune Software Users Manual NIStune Type 1 Hardware Installation Page 31 of 31 10 Reading the factory ROM image ECU Type A 1984 1985 These ECUs have two non standard ROM chips 1K and 8K which require special adaptors to read them in a standard EPROM programmer It is recommended you send the ECU to NIStune developments for reading and

Installation X1 The NIStune board will come supplied with two header connectors One is for the USB socket and the other connects to the ECU processor marked HD6802 or HD6303 Early model ECUs will require direct connection to the processor whilst later model ECUs provide a silkscreen connector socket which needs to be soldered to The CPU header connector plugs into connector X1 on your Type 1 NIStune board and has a marking on the connector to signify which pin is pin 1 Important note Due to recent changes in manufacture colour coded wires will no longer be used on Type I boards The pin I will be identified by a marking on the connector itself as well as the end of the wire 1 R W 2 A14 3 A15 4 E NIStune Type 1 Hardware Installation Page 18 of 18 A Early Model ECUs You need to solder the following wires to the HD6802 processor similar to the picture below ASE AT py E E E eet E A Y e A 2 T i i a L a m a r CI a z The header connector you are supplied with is marked with a 1 on the left hand side This corresponds to the on the diagram below Solder the ends of the wires to the CPU pins below ensuring that there is no possibility of the wire shorting to a neighbouring pin Hot glue over the wiring connections afterwards to ensure they do not move Any short circuit will stop the ECU from working and may damage it HD6802W NIStune Type 1 Hardware Installation Page 19 of 19
