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.
For discussing how to choose sensors and create a wiring harness for all Bowling and Grippo versions of the MegaSquirt® EFI controller.
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).
Now that I have got my MS-II running via my stock loom.
It's now time for me to think about removing the stock loom and replacing it with a real loom, & snap module fuse / relay box.
Something like this.
This it what my wiring in my fuse board will look somthing like.
This design will change meny times before I will build the real thing.
Fuse boxes for rewiring came up on the Datsun Roadster mailing list a while back and someone suggested some mid 80's Nissan Boxes. Which are made to bolt to a flat surface.
I have seen them in 10 (Micra), 15 (pickup), and 20 (Sentra) circuit configurations with the relays (3 or 4) clipped right to them. Fairly compact.
The terminals are relatively easy to pull out and re-arrange with the correct size wiring. Pick up a 2nd box to make sure you get enough of the larger wires with the terminal ends on them.
I used a Micra 10 cct box with 3 realys to add the MS to my car. The box with relays measures 15 cm by 8 cm by 8 cm tall. (about 6" x 3" x 3" )
Cost from the wreckers with the complete Sentra harness, 5 relays etc. $35.00
There were also a couple of diodes in the harness, encased in plastic, with a connector which was useful for 'neatly' bridgeing the relay for my fan control as outlined here: http://megasquirt.sourceforge.net/extra/outputs.htm
