DownloadBoschBip373IgnitionDriverMega. Squirt II Installation. All delivered Mega. Squirt IIs should have a 2 pin bootloader jumper generally blue installed on a 2 pin header marked BLD for bootloader near one edge of the board. If the jumper is only on 1 header pin, then you also have the operating program loaded, and if you plug in to a main board with a stimulator you should see the injector lights flashing, meaning the program is running. In most cases the jumper will be over both pins. This means only the bootloader program is loaded and you must load the operating program using Eric Fahlgrens downloader program. Download Bosch Bip373 Ignition Driver' title='Download Bosch Bip373 Ignition Driver' />Place Mega. Squirt II into the 4. Be sure the bootloader jumper is in place. Power up your Mega. Squirt controller. Click here to download the MS II Code Update Utility aka. Run the file, and follow the directions that come up. Download Bosch Bip373 Ignition Driver' title='Download Bosch Bip373 Ignition Driver' />This will install the downloader. You need to install the appropriate code for MS II. If you use the downloader previous step you can choose the update function from the File menu to get the latest code and INI from the internet in an MSU package. If you prefer to do it manually, or dont have an active internet connection, the MS II code can be found here www. The code you will load will depend on whether your is a V1 version no CAN chip or a V2 version w CAN. The best way to perhaps determine the MS II version of any board is that the V1 boards had green LPI solder mask, where as the new V2 boards are now blue solder mask. Next you may need to connect some jumpers. MegaSquirtII from the MegaSquirt PCB. This is used for the 12 Volt stepper motor driver. So MS II version V1 is green, and the latest V2 with CAN and the extra memory is blue. All MS IIs sold since early 2. V2 with the CAN chip. To load a ready to load. Download Bosch Bip373 Ignition Driver' title='Download Bosch Bip373 Ignition Driver' />When you purchase a MegaSquirt kit, the components typically arrive individually packed, with part numbers. As a result, while you should verify that you have. S1. 9 file to your Mega. Squirt II over the serial port, you need to use Eric Fahlgrens Mega. Squirt II downloader program click the link to download, which works from either a window or from the command line. If you miss any of these steps, youll have problem communicating. For more info, see step 4. Next you may need to connect some jumpers. Mega. Squirt II from the Mega. Squirt PCB. This is used for the 1. Volt stepper motor driver. You should add a jumper on the Mega. Squirt printed circuit board to provide a source of 1. V even if you arent using a stepper motor this will keep the stepper driver chip cooler. On a V2. 2 main board you run the jumper wire. X1. 3 and slightly below on the Mega. Squirt PCB. to pin 1. DIP i. e., JP1 6 on the Mega. Squirt PCB. On a V3 main board, follow the instructions in the V3 assembly guide. This is the one non plug n play setup between the 6. Ets 2 Save Game Editor more. HC9. 08. GP3. 2 processor i. Mega. Squirt processor and the Mega. Squirt II board. The problem is that the Mega. Squirt II needs the 1. V, but there is nothing like this running to the DIP4. HC9. 08. GP3. 2 for obvious reasons 1. Volts would cook the GP3. This is indeed one of the difficult things if one wants to keep on swapping between the old 6. HC9. 08. GP3. 2 and the MS II, in that if you re install the 6. HC9. 08. GP3. 2, you MUST. Remove the 1. 2V jumper, or. Bend pin 1. 6 on the 6. HC9. 08. GP3. 2 out such that it stands free and does not install in the socket. Snip the pin 1. 6 of the 6. HC9. 08. GP3. 2 short so it cant contact the socket, since it is not being used, or. Use a 4. 0 pin socket and snip pin 1. That way you can easily switch between MS I and MS II and not have to bendsnip the pin on the actual processor. Also, if you are going back to Mega. Squirt I be sure to unplug your stepper motor if you had one connected, because it will confuse and possibly damage your Mega. Squirt I if you dont. It will run for a while and then start resetting madly. This is in addition to the fact that you must unplug the 1. V line from the socket before re installing Mega. Squirt I. Then you have real plug n play between the Mega. Squirt II and the 6. HC9. 08. GP3. 2 from Mega. Squirt I. This is one of the issues Bruce is addressing on the new V3. V source pad. To use the ignition control and IAC control functions of Mega. Squirt II on a V2. Mega. Squirt PCB, you will need to add wires for these functions, and set a jumper or two. The ignition control wire should be hooked to the 5th pin on the JP1 header the row of closely spaced holes beside the CPU socket, near the copyright notice. The IAC pins are connected to X2, X3, X4, and X5 see the illustration below. To bring the connections out on the DB3. If you want to use the IAC stepper motor control function of Mega. Squirt II with a V2. What Makes Gilgamesh Accept His Destiny. Mega. Squirt PCB. X2 or DB3. 7 pin 2. X1. 1 goes to Coil 1, lead AX3 or DB3. X1. 2 goes to Coil 1, lead BX4 or DB3. X1. 3 goes to Coil 2, lead AX5 or DB3. X1. 4 goes to Coil 2, lead B. Note that the V3 main board has dedicated jumpers for the IAC, see the instruction in step 2. V3 assembly guide. Then you need to select the Idle ControlAlgorithm in Mega. Tune. In some cases setting the stepper motor to IAC Stepper Always On will cause the IAC to get hot. However setting it to IAC Stepper Moving Only, might cause a problem with idle speed changing from one start to another. You can test if your IAC is suitable for always on by leaving your stepper powered on the bench for 1. If it doesnt feel too hot to you, then set it to Always On. Apparently this is what GM does. But if you want to be safe they should test it on the bench for 1. IAC temperature frequently with your fingers. It may get warm, but it shouldnt burn your fingers just touching it. There are more details on the IAC page. These DB3. 7 pins are also used for V3. If you want to use the ignition control function of Mega. Strawberry Panic Game English. Squirt II with a v. JP1 header counting from the end nearest X1. Mega. Squirt PCB to the ignition module pin that receives a signal. You should also remove the Dave capacitor, if installed. If you are not using a FIdle valve using an IAC for example, you can remove Q5 from the V2. Mega. Squirt PCB, and connect a jumper from JP1 5 to the hole for Q5 closest to R2. This will give you an ignition control signal on the DB3. If you are using the ignition control, but not the IAC, you can connect the ignition control wire to any of the X1. X1. 4 holes, and retain your FIdle function. For example, on the GM 7 pin HEI module, you connect the Mega. Squirt II signal to the ignitions modules pin E. You will also need to wire other connections to your ignition module, depending on its makemodel. Here are more ignition details. Note that the ignition signal comes in to Mega. Squirt II on DB3. Mega. Squirt. However, it is important to understand that there are differences between the ignition input signal needed for Mega. Squirt II versus Mega. Squirt. Mega. Squirt needed one signal per ignition event, but the timing was not critical. Mega. Squirt II needs one signal per ignition event, but this signal MUST occur at the advance offset with respect to TDC. So you CANNOT use the negative side of the coil to trigger Mega. Squirt II because the coil already has timing advance built in, and using it for a timing signal will screw up the total advance severely. You must use the appropriate distributor or crank wheel for your ignition module. One other thing to note is that the Dave cap will delay incoming ignition pulses. The delay is dependent on frequency. It should be used only if people are tapping an ignition coil primary for fuel only. For any type of ignition control installation, the input source should be Hall or VR sensor or something else other than the coil primary windings i.
