The firmware itself is written in C/C++/ASM, with a Ford built RTOS.

You gotta start somewhere! I'm hoping the Admins of this thread will create a tuning section.

If you have any questions, let me know how I can help!

Yes, however, this is a pretty good kept secret by Ford. If someone had enough time and knowledge, they could find it fairly quickly.

Yes, any tune will adjust for any altitude. The MAF meters the incoming air and makes proper adjustments.

Also, the O2 sensors are a great indicator to the PCM as well...


I'm not a "tuner", I am a ecu software engineer. Its different.

2011 GT500 = It gets me from A to B

If you want good technical help. Put your Year, trim, engine, and PCM code in your post! Its easier that way
