[QUOTE="04OWwhipple, post: 16267231, member: 178956"] I have been slowly working through tuning my car on a Haltech ECU. I would have to target an AFR of aroun 13.3 - 13.5 in order order to get it to idle smoothly. If i would bring is up to 14.0-14.5 it would start to pop hear and there with little half misfires. The base tune had the zero demand idle timing set at 28 degrees. I backed it down to 18-20 degrees and now am able to lean out my AFR to 14.5 at idle without having that light popping/half misfires. Just curious what people are running for timing at idle? [/QUOTE]
