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.

Hooked up my ignition on the weekend, but it seems I'm really not in control. I confirmed 5V is reaching the ignition module via the bypass, but adjusting the timing made no difference. I slapped the MS on the stim and measure the voltage output on the EST line and it is only 0.85V. That really doesn't seem right to me.
For my MSII wiring I ran a line from pin 5 on JP1 to the DB37 pin#36.
Running a MSII V2.2 with the 2.883j code. 4 Cyc 1.9L turbo charded 1992 Saturn.
Thanks for any help.
Why did I ever think a turbo Saturn would be a good idea?
My cable from the MSII to the relay board is kinda missing a wire on pin 36 Moved everything over to pin 25 and now everything is cool. Except the car won't start and run which is how I know I'm controlling the timing. Off to the megamanual I go.
Why did I ever think a turbo Saturn would be a good idea?
I started the car running on just the ignition module and leaving the MS EST line and bypass unplugged. When I measure the voltage on the EST line it is 3.39V. Now I plug the EST line into the DIS module and the voltage drops to less than 1V. I really have no idea what the reason is. Any ideas?
Why did I ever think a turbo Saturn would be a good idea?
Okay, hooked up the stock ignition and probed the EST line while car was running shows .239V at idle so it looks like things are okay from that perspective. Still as soon as I apply 5V to the bypass when running on the MSII the engine stalls. So this has to be my ignition settings. Back to the drawing board.
