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).
Hi!
I am trying to run ms2 on my Opel Kadett. It's an 2,5l 4cyl engine. I have Edis4 wired to my ms. When i try to start the engine, the rpm peaks to around 120rpm, then it falls to zero again.
Anyone have any idè what could be the problem?

Do you mean it's starting from cold, revving to 1200 rpm, then cutting out?
If so, it sounds like the cranking pulses are about right, but the warm-up mixture too lean.

No, it is not fireing at all! But i have found out some more now! My Edis is wired like this: http://avs.spot-mate.com/images/tech/edis4.jpg The vr sensor is sending it's signal to the edis unit. But what kind of signals should the edis modul send to the coils?

It sends pretty well the same sort of signal to the coils as any other coil based system. It should be a pulse to build up the flux in the coil which when stopped causes the spark due to the flux collapsing.
The EDIS system should fire regardless even when not connected to MS - it has a limp home function. If the VR sensor is correctly related to the trigger wheel this should be a constant 10 degrees BTDC. Have you used a timing strobe light to check the spark is approximately timed correctly?
