EZ116K daughterboard assembly and installation guide
So, now you've got yourself one of my daughterboard kits we should head on to the last chapter of the “Make your EZK chippable” story; Assembly and installation of the daughterboard.
You don't need any exceptional skills to be able to assemble and install this board, but some experience with soldering electronics wont hurt. Still; If you feel you aren't up to the task, just ask someone else to assemble it for you. Especially when a backup EZK isn't available.
UPDATE:
I am also offering EZK's with the daughterboard already installed. PM me for more information and pricing!
Tools needed (just to be complete)
Low power soldering iron. So leave that 250W iron in the shed.
Flux cored solder. Duh...
Small cutting pliers
The kit should contain the following components
28 Pins DIL IC Socket (Eprom)
20 Pins DIP IC Socket
20 Pins board header
3 Pins jumper socket
74HC573 IC
2x 1uF MKT Capacitor
4k7 Resistor
Jumper
Small piece of desoldering braid.
Daughterboard assembly
Although the assembly of the board itself is very straightforward, you still want to take note of the following hints;
IC (Sockets)
1.Note the orientation of the sockets on the board!
2.Don't put the IC nor Eprom in their sockets at this point!
Capacitors and resistor
1.The capacitors are of the bipolar type. This means you can put them on the board anyway you want.
Headers
1.Don't place the 20 pin header on the board. The header will be mounted on the EZK first!
Daughterboard installation
To install the daughterboard you only have to remove EZK's the top lit.
You may notice the holes needed for the daughterboard header are filled with solder. Before the header can be mounted, the desoldering braid should be used to remove the solder.
Desoldering should be done from the backside of the PCB. As you can see on the pics; the tracks on the top side leading to the holes are very fragile and can easily separate from the PCB holes when disturbed.
Once the holes are clear of solder the header can be mounted. Long pin side goes to the EZK.
Now the daughterboard can be mounted on the header. Take notice of the spacing between the IC on the EZK and the daughterboard!
When ready, the small IC can be put in its socket. Don't put in the Eprom!
Set the jumper to the 2-3 position.
Testing
Put the EZK back in your car and try to start the engine. The engine should NOT start! You know your car; Don't crank the engine longer than absolutely necessary. You may flood the engine!
In case you've just changed the oil or whatever, you could disconnect the injectors and just check for spark.
With this test you make sure the EZK isn't using its build in software anymore.
When the EZK passes this test you should disconnect it and put in the Eprom. Reconnect the EZK and try to start the car. Now the engine should fire up normally!
Congratulations! You've just made your EZK chippable!
