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 am trying to find the right F injectors for my conversion. Reading the megamanule, it says to find injectors off roughly the same HP motor. There is a motor that produces 3 HP less than mine but is also 200 cc smaller.
With the calculator I can get the lbs/hr(10.3) that my motor will need but I cant seem to get the conversion to work to see if the injectors off the smaller motor will work on my app.
The motor I am going to convert is a 32hp,2cylinder motor with a max of 3600rpm. I has a 90mm bore and 78 mm stroke which is the same bore and longer stroke than my 914 porsche. My thought was ,I might be able to use the same injectors that the 914 uses but they have the capability to flow enough for 250 hp and will probably be too big.
The difficulty is that this calculator won't tell you if the engineers picked injectors that were just barely large enough for the motor, or decided to go with much larger ones than necessary. Still, it looks like a small enough difference in power output that the worst case is you may need to bump up your fuel pressure a little bit.
