Me and my dad rebuilt the 5.7 hemi out of a 2008 Dodge Charger RT, and we are struggling trying to get the car to idle. We are brand new to hp tuners and both feel a little overwhelmed with all of information out there and not completely understanding what each parameter actually does.
The car has a comp cams sr2b camshaft (223/235 114LSA), ported 5.7 heads, and stainless works long tube headers with catless midpipes.
We have been reading the forums and watching some videos and we have made a little progress tuning. We disabled the MDS, EGR, and the rear o2 sensors. We also raised the idle rpm, and adjusted the min base and startup spark tables. The car will start and idle ok for about 10sec before the car starts dumping fuel and pulling timing until it inevitably stalls. Ill attach the tune and log data. We think the car is trying to warm up the catalytic converters that are no longer there and we are not sure how to correct it. I increased the o2 airflow delay a few times in hopes it would help since the sensors are down by the collectors now, but with few noticeable results. Any advice or links to relevant threads would be greatly appreciated. Even getting the car idling and running good enough to cruise around the neighborhood would be a much needed win at this point
