Not familiar with LSPI ... what is it?
It most commonly affects turbo direct-injection motors, google Low Speed Pre-Ignition. Searching LSPI in the EcoBoost subforum on this site would be helpful as well.

the same applies to non DI engines too.

High Load – Low RPM

I believe that a large amount of failure is due to the driver. Even the most cautious of drivers can cause significant amounts of knock on any tune. This isn’t to say that the drivers are dumb or have poor skill, it’s simply that most drivers are unaware of the load they are putting on the engine and how that correlates to the tune.
Simply put, one of the worst things you can do to your turbo engine is to load it up at a low RPM on the highway in a high gear. Building 14 – 18 PSI of boost at 3000 RPM is a high load : low RPM moment that may not have been properly tuned for your vehicle. Most tuners don’t bother sticking the car in 5th or 6th and road force testing it for knock at low RPM. Subaru and Cobb both recommend getting further into the RPM range before going WOT (3500 – 4000 RPM).

I really like you're handling the situation, taking the blame and not blaming anyone else.

You did everything possible that was discussed on these forums, going back to stock, key cycles, etc. and in the end, it didn't work. I'm very sorry that it happened to you and other people should def. learn from this. The "Tune" is the number one mod with the Ecoboost and unfortunately, it is the one tune where if something catastrophic were to happen, you will have to foot the bill to fix it.

In other words, if you don't want to foot the bill for a new engine, don't tune your car. It's def. a gamble since I seen stock engines blow up and they will blame your tune.
Yup a tune is a must have on any car to me but unfortunately I got the short end of the straw this time. I'm not rich by any means so this does hurt me and if I build the motor it will most likely take me a full year to have it completed. Same to pay off the loan to have the dealer put in a new motor. I was down about the issue for the first few days now I'm learning to live with the problem because there's nothing I can do. But this will probably be the last 4 cylinder turbo I ever own. They seem to be the riskiest cars to modify. My other cars were all N/A and we're heavily modified and I never had a problem.

yeah, really sorry about this. it sucks to have that much experience on modding/tuning and having this happen with barely any miles on it.

LSPI, as others mentioned, is likely the culprit here. I'm surprised your car wouldn't downshift once demanded a high load. Typically LSPI is more prevalent with manual cars as the owners don't care to downshift. An auto should. Sorry you had to learn about this the hard way D:

LSPI can blow up a completely stock engine as well.
No engine should blow up from LPSI on a factory tune. The factory tune is designed to pull timing and boost when the knock sensors detect any pre-ignition.

Seriously? And I'm taking it you are a tech and speak from experience correct?

Well, a member here on this thread spun a bearing with just a CAI but I'm guessing that he had a different problem.

Also, the OP has a stock tune with a plethora of mods.

Yes no stock engine SHOULD, too bad there are plenty of documented cases where completely stock turbocharged direct-injection motors blow up.

Make some popcorn, google LSPI and do some reading.

Don't listen to that service adviser.



Regardless of what parameters are modified, any aftermarket tune voids the warranty on the powertrain. It's as simple as that.

Not entirely true. Technically Ford should still tear down the engine just to ensure it wasn't a faulty part. Then decide from there. And foot the bill to the customer if it's his fault. But more often than not, a tune would be the cause. I'm not entirely sure how you could determine a part was faulty from the factory and differentiate from potential damage of a tune.

Joe, I'm sorry to hear that! What caused it to blow up do you know?? This whole thing about key cycles is BS.. That is why my car is fully stock now and I really don't have 10k in my bank to front for a new engine.

Was it tune related or something like the piston rings didn't seat correctly from factory?


Did it give you any warnings, check engine lights before it went out?

Sorry to hear bro, hope you get it sorted out as well.
Please explain whole piston rings theory

Why I wouldn't why waste the time and money. When they find it had been tuned

Pre-ignition doesn't cause spun rod bearings. Rod bearing failure is the result of a manufacturing defect, oil starvation, or abuse.

Anything is possible from other manufacturers. Mazdaspeed 3's will toss the rods through the block if you load them up on boost at low RPM, even in factory form. I was speaking specifically about GTDI Ford engines.

guess Adam can't say one of his tuned cars hasn't blown anymore. Really would like to know why Joes Motor blew.

And no I don't believe his tune was the problem.
