hitmanpc Posted February 15 Share Posted February 15 So I am new, may be obvious but just putting that out here; But, what is mechanical returnless fuel system? Did some inter-webbing and it looks to be a conversion from a returnless to return style system and I just want to make sure that I understand the values in PCMTEC software: I have a return style setup and want to "play" or "test" with these types of scalar settings. Extra ???: If anyone knows of some settings for a stock (pats deleted/off) 2015 coyote return-less ecm to a return style ecm configuration please let me know. I have gone through what I think are ford control pack configurations on the calibration list however I am not getting any spark quite yet. Thanks in advance for any information.

hitmanpc Posted February 18 Author Share Posted February 18 So after getting the data logging hooked up and understanding a tad bit more it seems that my pats may be enabled on this ecm. What are some common PIDs to look at when determining if pats is still enabled? Thanks again if anyone knows. I will also post this on other forums and if I find out I will reply to this thread.
