Recien le quite la mega a la swift para verificar todo el ensamblaje de la misma. Tengo una duda en la parte de selecionar la corriente de la mega con los "jumpers" . Les escribo ya que fue un companero quien me ensamblo la mega y la programo yo solo instale el cableado en la swift. Ya le cambie todas las resistencias que Caaarlo sugiere en su guia. Pero en la parte de seleccionar la corriente cual selecciono segun el manual de ensamblaje de Megasquirt que les dejo a continuacion o solo basta con soldar el LED 14 y tirar el cable a el pin 36 de la mega. A continuacion el paso 65 del manual de ensamblaje de la mega.
65. It is choice time again. In this case, you will decide whether to populate the high-current ignition driver circuit. This circuit can be used to drive a single coil in a distributor application. In conjunction with an appropriate input signal (from a VR, Hall, or optical sensor, or even points), it allows you to eliminate a separate ignition module, such as a GM HEI 7 or 8 pin module, and run the coil directly from MegaSquirt.
If you aren't sure what output circuit to use, check to see if your ignition is on this list and follow the instruction in the link if it is:
•GM HEI
•GM DIS
•Ford EDIS
•Ford TFI
•Bosch 0 227 100 124
•MSD 6A
•Direct Coil Control
The following instructions are for MS-II™ only. If you are planning to use MSnS-E, please see the MSnS-E site for instructions on how to wire the high current circuit. If you are using MS-I without ignition control, you can either complete this step as with MS-II™, or skip it (it doesn't matter which since the ignition won't be hooked up).
•If you are not using the IGBT high current driver circuit, but want to use the MegaSquirt-II output to control an ignition module (7 or 8 pin HEI for example), jumper JS10 to IGN to bring the signal out on DB37 pin #36. You do not need a pull up, the processor port has one enabled already (at 5 Volts). Skip ahead to step #66.
•If you wish to install the high current ignition driver circuit:
a. Install and solder R43 {13FR010-ND, 0.010 Ohm/3 Watts, brown-black-red}. This is located near the DB37 connector, close to the heat sink.
b.DO NOT install R57 {47KEBK-ND,47K Ohms, 1/8W}. It creates problems with the signal to the VB921 (or BIP373), so leave it out. DO NOT install a jumper, simply leave that spot 'unpopulated'.
c. Install and solder Q16 {497-2716-5-ND}. This is a specialized VB921 (or BIP373) dedicated coil driver chip. This mounts to the heat sink near the DB37 connector. An insulator is not necessary for the VB921, but is essential for the BIP373. The distributor you bought your kit from will indicate which you have, or follow this link: BIP373 for more info. Use heat transfer compound between the component and the heat sink.
d. Install the appropriate jumpers:
For MS-II™, install jumpers:
IGBTIN (near the heat sink side of the DB37 on the bottom of the board) to JS10 (under the 40-pin CPU socket on the bottom of the PCB)
IGBTOUT to IGN - near the Heat sink end of the DB37 on the bottom of the PCB (this brings the ignition control signal out on DB37 pin #36)
For MSnS-E user on MS-I, see the MSnS-E web site for additional jumper connections and to enable the ignition output.
Note: If you are using the high current driver circuit to control an ignition module instead of a coil directly (and don't want to use the processor port directly - i.e., you have not jumpered JS10 to IGN), you likely need to to add a pull-up resistor. This allows the signal to go both high and low, rather than floating and low). Also, the IBGT will invert the signal from the processor, so your 'Spark Output' setting will need to be reversed.
