This means the injectors are not fired in any particular order, just the same number of times per unit of time. It does not matter which fuel injectors are connected to which bank of fuel injector drivers using batch injection. Many users opt to group the injectors according to the corresponding cylinder's piston position. For instance, in a four cylin… text/html 2010-08-16T14:34:27-04:00 Paul Symansky http://www.symtechlabs.com/support/knowledgebase/megasquirt:start?rev=1281983667&do=diff Articles Mechanical * Fuel Injector Calculator * Chrysler Temperature Sensor Calibration Wiring * Proper Grounding * How to Solder Wires Together * Working with Coaxial Cable * Adding an ASD Relay to the Fuel Pump Relay Output Firmware * Megasquirt Firmware Downloads * Flashing Firmware into Megasquirt ECU's text/html 2010-06-21T15:29:37-04:00 Paul Symansky http://www.symtechlabs.com/support/knowledgebase/megasquirt:usb-serial_adapter_connectivity?rev=1277148577&do=diff Here are a few tips and tricks for successfully connecting to your Megasquirt ECU using a USB-serial adapter.

Inaccurate sensor readings due to signal noise are not only a nuisance, but a hazard. The best way to prevent unwanted signal noise is to ground the Megasquirt ECU, sensors and actuators at the same spot. Doing so guarantees all ground points are at the same voltage relative to one another: 0V. text/html 2009-11-30T15:49:17-04:00 Paul Symansky http://www.symtechlabs.com/support/knowledgebase/megasquirt:lost_comm1?rev=1259614157&do=diff If you were previously successfully communicating with your Megasquirt ECU, the firmware is likely corrupted. While extremely poor wiring and severe electrical noise could corrupt the firmware, the more likely culprit is an improperly configured serial connection, or tuning software. Besides ensuring your serial connection is sound, you will have to flash your ECU with the latest available firmware to restore functionality. Be sure the firmware in your ECU matches the .INI file your tuning so… text/html 2009-11-30T15:46:52-04:00 Paul Symansky http://www.symtechlabs.com/support/knowledgebase/megasquirt:flash?rev=1259614012&do=diff Most Megasquirt users will upgrade their firmware at some point or another. Follow these simple steps to ensure the upgrade process goes smoothly. MS1/Extra Acquiring the Firmware Begin by downloading the latest stable firmware release package. Save it to an easily accessible location on your computer, such as your desktop. The file will be compressed as a ZIP file, so decompress its contents. The resulting folder must be on the same hard-drive as your tuning software. text/html 2009-11-15T16:02:07-04:00 Paul Symansky http://www.symtechlabs.com/support/knowledgebase/faq:shp_intl?rev=1258318927&do=diff If your order has already been shipped, a tracking number will automatically be emailed to you via the courier.
