New at Tuning Question
New at Tuning Question I had a WOT dynotune done already and a hptune car runs perfect except for one thing when coasting under say 10 mph or coming to a stop it still has surging and very rarely stalls until I come to a complete stop then it idles fine. I'm about to get a wideband hopefully this will correct it. Anyone have any tips.
The throttle cracker table is the place to adjust airflow when coasting to a stop. If the idle is good when stopped and your IAC counts are good, don't mess with running airflow tables. The throttle follower is more useful for when you snap off the throttle (it would be adjusted if the rpm dips when you snap off the throttle and then recovers), its not so much used when coasting. Make small adjustments (add about .5 gm/cyl at a time) to the throttle cracker table in the lower rpm ranges and I think you will solve your problem...
