hitmanpc Posted February 15 Share Posted February 15 (edited) 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.
