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.

Iam putting a MSII Ver 3.0 together and Iam little confused on FIDLE setting.
So if Iam wiring into a two wire IAC valve. Do I use the TIP 120-122 transistor? I guess Iam confused where I put the Transistor on the board?
And what wire is it on the DB37?(is it one of the Stepper Outputs?)
In Help would be Awesome!
Thanks!!!!
for fidle (used on old cis injected engines) u dont need to replace any transistors. u need relay to switch it on/off (actually , when engine warms up and ur fidle module is bolted to engine , it will close anyway)
for pwm idle (on newer european engines , bosch two wire pwm idle valve)
u need to use TIP transistor and pwm idle valve will connect to same pin as fidle usually connects (directly , without realy)
