The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.
This forum is for discussing ignition setup, tuning, and troubleshooting for MicroSquirt (TM)

I am currently using a 420a coil off of a Dodge Neon on my yamaha motorcycle with a XJ900 engine. I am using the Latest Micosquirt system. I have the coil 12v to center pin and wired the microsquirt pins 11 & 12 to the other two pins on the 420a coil. Will this work? I tried cranking it over with one of the spark plugs out and there was no spark. I have a very limited knowledge on this, but everything else seems to be functioning except for this. I have one trigger input(vr). I see a lot of megasquirt examples, but no microsquirt? Can anyone please help me on this?
From what I've read, the 420a coil module has no internal drivers; it is a 'dumb' unit, and needs high-current drivers. As of the newest version (V3.0), the MicroSquirt no longer has internal drivers either. Attempting to drive a high-current coil directly from the uS can damage the processor!
