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.

I recently purchased a '07 Chevy 4.3L V6 engine for my sand rail. I also got the MSII V3 and Stim Jim. Does anyone have a code for this motor? I have the MAF for the motor as well and would like to use it since it is going to be a stock application. There is also somthing different with the HEI module on the motor when compared to the ones on the support/manual site. It has a 4 pin HEI on there but it does not look anything like the ones shown, any ideas or concerns here? Any help with additional wiring info would be greatly appreciated since I am extremly new to the automotive computer application side. Have plenty of electrical and programming experience.
This one looks like it's quite different from a classic HEI. As near as I can tell, it has a 12 volt Hall effect sensor on the crank reading a 3 tooth wheel (works like a more accurate distributor pickup) and I'd just use that with direct coil control.
See the sections of the manual on distributor pick-ups and direct coil control. The exact needs of this particular engine are not all that well documented and you may need to break a bit of new ground if you want to do this without swapping to an early distributor.
