Can you add custom PID's?

My torque pro pid info for the oar reading is below.

It took some digging, but I found the following:

These are the only PIDs I found regarding Octane Adjustment, so I’ll give them a shot. Thanks

Edit: Learned Relative Octane Adjustment displayed -1.0, so I assume that’s the proper gauge, since that’s the target reading, correct? Thanks again

The downpipe is the only thing that could have even the remote chance of causing any issues, a check engine light for turbo overspeed and an emissions code from the 2nd O2 sensor should have been the only result though. Less intake restriction and cooler charge temps shouldn't have any ill effects on the motor otherwise a high flow drop in filter and cool weather would be blowing up cars left and right.

The popping noise is the engine responding to detonation, if the engine is detonating easily on the stock tune persistently through different tanks of fuel then a physical defect exists within a cylinder or cylinders that is causing undesirable combustion conditions. A timing cover leak is a symptom of high crankcase pressure and smoke out the tail pipe suggests a bad ring or cracked piston when the other factors are considered.

I would theorize that a pre-ignition event occurred in cylinder #2 that caused damage to the piston in such a way that the piston would allow oil to enter the combustion chamber and cause further detonation when the engine was put under load, updating the tune for the downpipe and intercooler would have only added more fuel, boost and timing resulting in a second pre-ignition event that snapped the connecting rod and sent it out the side of the block.

The cause of the original pre-ignition event is unclear, severe lugging of the engine in a higher gear and not so great fuel could have done it or the cast cylinder could have had a flaw that caused it to crack, a lean condition from a faulty fuel system component is a possibility but should trigger a code, a faulty low side fuel pressure sensor would cause drivability issues but normally not enough to damage a factory tuned engine.

It could be many things but if Ford is willing to fix it under warranty without giving you any hassle over modifications then they are confident that the nature of the failure was due to a manufacturing error and therefore completely beyond your control meaning it was going to happen no matter what you did.

Greetings,
If this happens to a stock Mustang Echoboost (no modifications), and Ford repairs the manufacturing error, is it possible for this to happen again?

Possible? yes, it's possible, but not probable. It's most likely that the car will be fine after the repair and have a long life. What happens though is that owners lose faith in the car, and start to feel like it's going to fail them again.

Your response is appreciated. I am in the process of purchasing a used 2018 Echoboost Premium (50K miles). I was told that previous owner installed an after market exhaust/muffler (no other modifications were brought up to me). At time of test drive, the engine light was "on", and I felt the car drove normal. I was told that it was a cam sensor and car would be ready the next day to finalize purchase. Dealer updated me and told me that in fact it was a "head gasket" and that they had ordered the part. And that they are going to send something to the machine shop (not sure if it was the part ordered or an existing part on the car that needs to be machined). It is a pre-certified Ford Vehicle. The car is in my price range, but should I be worried?
