Please see our article on serial port connectivity for information on connecting to your MegaSquirt ECU using your computer's built-in serial port. text/html 2012-07-26T01:28:05-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/megasquirt:grounding?rev=1343280485&do=diff Signal noise can be a significant problem while tuning any engine management system. 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 sensors at the MegaSquirt ECU, and ground the MegaSquirt ECU directly at the engine block. Doing so guarantees the MegaSquirt ECU and sensors are using the same ground reference. text/html 2012-07-05T18:40:34-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/megasquirt:terminology?rev=1341528034&do=diff For all intents and purposes, there are two main components in a MegaSquirt ECU: the main board and the processor. The v2.2, v3.0, and v3.57 boards are the three main boards available. The v3.0 board, as you may have guessed, is newer than the v2.2 board and offers many more standard features. We only recommend the v2.2 board for bare-bones installations; for applications with few technical requirements and a very small budget. The v3.57 board is a surface mount version of the v3.0 board. … text/html 2012-05-30T13:24:51-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/faq:warranty?rev=1338398691&do=diff Most SymTech Labs products are warrantied against manufacturer's defects for a one year period following purchase.

SymTech Labs cannot guarantee that a CEL will not appear, but if used properly, our products will not negatively impact your vehicle. In many cases CEL's merely warn you of malfunctioning (or modified) systems.

It is your responsibility to determine whether any of SymTech Labs' products violate local, state or federal laws in your area. In areas where the addition of a SymTech product compromises the street legality of an automobile, the product in question is to be used for OFF-ROAD use only.

For safety purposes, it's best that Megasquirt controls this relay. The same logic that controls the fuel pump relay can be used to control an ASD relay, but unfortunately a Megasquirt ECU's fuel pump relay output cannot sink current from both. Here are a few techniques for connecting both an ASD relay and a fuel pump relay to a Megasquirt ECU's fuel pump relay output. text/html 2012-05-15T20:27:24-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config3.png&ns=megasquirt&rev=1337128044&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config3.png?w=500&h=295t=1337128044" alt="megasquirt:ms_relay_config3.png" /> text/html 2012-05-15T20:27:24-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config2.png&ns=megasquirt&rev=1337128044&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config2.png?w=500&h=362t=1337128044" alt="megasquirt:ms_relay_config2.png" /> text/html 2012-05-15T20:27:23-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config.png&ns=megasquirt&rev=1337128043&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config.png?w=500&h=207t=1337128043" alt="megasquirt:ms_relay_config.png" /> text/html 2012-05-15T15:03:23-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config3.jpg&ns=megasquirt&rev=1337108603&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config3.jpg?w=500&h=297t=1337108603" alt="megasquirt:ms_relay_config3.jpg" /> text/html 2012-05-15T15:03:10-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config2.jpg&ns=megasquirt&rev=1337108590&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config2.jpg?w=500&h=380t=1337108590" alt="megasquirt:ms_relay_config2.jpg" /> text/html 2012-05-15T15:02:58-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams_relay_config.jpg&ns=megasquirt&rev=1337108578&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms_relay_config.jpg?w=500&h=185t=1337108578" alt="megasquirt:ms_relay_config.jpg" /> text/html 2011-01-28T03:04:08-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Ams3_boot.jpg&ns=megasquirt&rev=1296201848&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:ms3_boot.jpg?w=360&h=424t=1296201848" alt="megasquirt:ms3_boot.jpg" /> text/html 2011-01-28T03:02:22-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Aflash5.jpg&ns=megasquirt&rev=1296201742&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:flash5.jpg?w=500&h=250t=1296201742" alt="megasquirt:flash5.jpg" /> text/html 2009-11-09T01:35:12-04:00 symtechlabs http://old.symtechlabs.com/support/knowledgebase/?image=megasquirt%3Aflash4.jpg&ns=megasquirt&rev=1257748512&tab_details=history&mediado=diff&do=media <img src="/support/knowledgebase/_media/megasquirt:flash4.jpg?w=500&h=168t=1257748512" alt="megasquirt:flash4.jpg" />
