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 is the place to ask general MegaSquirt® questions if you are just getting started.

Forum rules Read the manual to see if your question is answered there before posting. Many users will not reply if the answer is already available in the manual.
If your question is about troubleshooting, configuration, or tuning, you MUST include your processor type (MS-I or MS-II) and code version in your post. If your question is about PCB assembly or modifications, you must also include the main board version number (1.01, 2.2 or 3.0).
My project has evolved over the years. I am now building a one off 5.6L version of the 3.5L V8 engine in my car. The new engine has no fuel system and I plan on using MS however I cannot start and break in a new engine while tuning a new MS system. So my idea is to install and tune the system on my existing 3.5L engine running at a proportunatly reduced fuel pressure then transfer the system to the 5.6L engine and increase the fuel pressure to the proper pressure-then the new 5.6L engine should start and run well enough to drive the car??
Instead of changing the fuel pressure, simply change the Required Fuel number to match the new engine displacement (and injector size, if you're changing that too).
Thanks for your reply-yes I will be using the same injectors. Everything will swap over to the new engine-the only thing that will change is the displacement. The first few minutes are very important to a new engine so I am concerned it will start and drive right away.
