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.
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). For tuning/troubleshooting questions, please attached a datalog and your MSQ file to your post.
I have a 240sx running MSII on the stock distributor, I can get the car to turn over and one cylinder will fire and then it's like the MS turns off for a second, or stops sending an ignition signal for a second and then it will start up and fire one cylinder again. I feel like it must be a software problem because I'm getting fuel and the mechanical timing and trigger angle are spot on. Any help would be much appreciated, this project has been driving me crazy for going on 2 years now and I'm so close but I can't get it started.
Looks like it's getting a very brief signal and then losing it - this causes the ECU to show a constant RPM for a brief period. Could you post a copy of your MSQ?
The same way you posted a copy of your data log. Below the Save - Preview - Submit buttons, you will find a pair of tabs marked "Options" and "Upload Attachment." Click the Upload Attachment tab. Then click the "Browse" button that appears. A file open dialog box will pop up. Select the file, then click Open. Then fill in the description in the field below the file name. Once you have all that, click Add the File. Repeat this, starting with "Browse," to add more files. Once you have these all attached, you can enter your post and the files will be attached.
You should have mentioned MegaTunix - MSQ is a MegaTune / TunerStudio file format. MegaTunix uses its own file format. I need your tune file, and would prefer you post it in MSQ form if possible.
