Did you know there are limits in your Cadillac ATS-V that are programmed based on engine run time (ERT)? ERT as in the amount of time the engine has been running that session.

The intercooler pump won’t start running for the first 10 seconds. Hard to make a lot of boost with no intercooler flow, but 10 seconds is a pretty short delay.

The intake cam and exhaust cam won’t vary their positions for the first 2 seconds (not much of a restriction there!) but again, don’t start the ATS-V then gun it and expect full performance.

If the engine coolant is VERY cold, under -4F, there is a fuel cut out after 5,200 RPM.
