Hey everyone,
Ive got a 2007 wrangler with a 2014 truck 5.7 eagle motor. It has a texas speed 220/230, short headers, obviously no mds and a cold air intake. it has valve springs and pushrods with a cam lock too. When this thing is idling it surges a little and will intermittently pop out the exhaust. I thought it was the base spark and torque reduction spark tabledifferences because it would randomly retard spark from 15deg to -11deg and pop, so i matched the torque reduction and base spark maps and it nearly stopped doing it when i matched the two tables. I have been chasing this issue for a few weeks and have finally gotten it to idle semi well. I know the HO2S heater code is concerning but it is working fine, i have tested it with multimeter and ir thermometer. It is just the pcm. I had ordered a new pcm and the codes went away but it bricked on me when tuning it so i had to put the old one back in for now. The jeep runs pretty good other than the loud popping at low rpm load, and idle. I know the ve tables still need a little bit of work but im really lost with the idle situation and i need some help getting it dialed in. if anyone is willing to point me in the right direction or help me out that would be awesome. my options are limited because i live in fairbanks alaska where there are no in state tuners. Thanks in advance guys
