My buddy has this 13 ram RCSB with the 5 speed and a 5.7. He installed a 270 cam IIRC with a limiter. Well, I tuned the truck via speed density, everything is great. idles great in park and neutral, but just surges like a MF in drive or reverse. Once its moving its fine, but as soon as you stop at a light it surges up and down. between 700 and 1000.
I do all kinds of changes, mess with TB airflow, small range and large range tables. No change really.
I decide to change to stock the factory minimum spark tables and torque reduction tables under the spark tab. Well, after putting the factory values, the truck idles great in park and drive. The problem is as soon as you give it throttle input, the timing goes super negative, somewhere round -20. I have to set the minimum spark values around 10* for it to run fine. So it seems my problem is the min spark tables causing my surging issue, but as soon as theyre put to factory, i just get neg timing with the slightest bit of throttle. I go WOT, and it stays negative for a good 5 seconds, then all of a sudden the timing surges back to positive values. No KR. I've tuned 3 or 4 cammed dodges, this is the first time I see this.
Any clues? i have messed with absolutely everything i can think of. Every switch under auto trans tq management is disabled, as that is how the stock read came.
