exagerated cam overlap on Pentastar at PT 1700-2000 rpm
I runned some numbers and see attached: I observe 40-57 Degrees cam overlap (calculated from VCM tables and proven practically driving) on the range of 1700-2000rpm on Partial Throat, what I think explains why the torque feels on those rpm like a bike on my pentastar....
1. Can anybody propose to me / guide a direction on how to improve this? should I just change the VCM Exhaust Cam tables to not allow an smaller number than 90 degrees at partial throat? or what you guys recommend?
I was thinking if asking for a 2018 wrangler 3.6 stock cam PT tables and copying them, as those have EGR so I would expect don?t make this Exhaust recirculation cam overlapping?
2.- One other question: how possible that my 750mg aircharge/cylinder overlap looks so far from the WOT? I would expect WOT and 750mg/cyl aircharge to be scheduled very similar instead... but thats not what I observe. Suggestion?
Thanks so much!Attachment 118057
