Cylinder Pressure Limit ,,, 2014 GT500

[Abdulaziz_pe]

any one experienced this case on these 5.8 ?

while tuning on the street i recognized a drop in timing advance.

i relogged it monitoring the spark source and manifold temp, once it reaches 60?C (140?F ) the source switched from Boarderline to Cylinder Pressure Limit.

i was tuning it the other day and weather was awful, almost 110?F and i didn't experience any issue with timing or this Cylinder Pressure Limit.

the day i saw that issue was better ( 98?F ) i thought something happened to the intercooler water pump due to the increase in manifold temp. but it is low mileage vehicle.

any clue ?

we found intercooler water pump fail in low mileage 2014 so better to have a look on it.
