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.

Is PT7 (processor pin 10) hooked to AN07 (processor pin 34)?
The reason i ask is because we wanted to use spareadc2 and it seems it is hooked to PT7 at the processor , we can turn PT7 on in the output port settings and the ADC7 gauge will go from 14 to 1024 as PT7 toggles on and off but stays at 14 with our 0-5v sensor hooked up.
I ran into this just yesterday trying to hook up a fuel pressure sensor. If u use pin 5 on the amp seal, adc7 doesn't work. Adc7 does work on pin 29. This is with extra code 3.0.1x

PT7 was tied to ADC7 so the same pin could be used for a voltage or frequency based MAF. I you are not using a Frequency-based MAF, then make sure this isn't set in MT/TS and makes sure PT7 isn't selected as a spare port output. If configured that way then make sure you haven't indicated you have a second EGO sensor. If you haven't, then you should be able to read and record ADC7 as a voltage on the knock sensor gauge, but leave knock control disabled.
The connection should be to pin 5, pin 29 is tied to ADC6. These are hardware connections, the same for all software, but the output variable you read the adcs can be anything. The above paragraph applies to standard code.
