Before this happened so I have no clue why this happen Prb it went way to lean
But the dealer in cail did the motor so now the car is in ny

Take off whatever tune box you have on there.

It would be a OBD remap so the car needs about 45 mins to remove map and lock the ECU.

You ideally also need to put a battery charger on the car to stop the battery draining but it may be OK without it.

Either way if its at the dealer the map is not coming off.

Sounds like the tune just made the issue happen a lot sooner.

Oh,he said he only had the tune on for 20 minutes.

It would be loaded and then he drove it for 20 mins

[technician117]

So you had lean codes before you installed the tune?

[Monteblueem5]

Yes I loaded the tune night before took it for a 10 min
Drive car was fine next day installed downpipes
Went inside took a shower came back out took it for a 20 min ride
That’s when it went boom but yes I had lean codes before all this
I was thinking maybe it was software problems I guess not
So i did reflash car back to stock and relock dme the only thing I left
Was the downpipes as I could not do it on a busy street the only good
Thing is that my tech is my boy I know many years and you really can’t
Tell there’s downpipes because the sheld blocks the pipes on top

Did you use a battery charger?

[Monteblueem5]

Lol because I was in the street I use my other car I put jumper cables and
And I let my other car run

Good idea

[BeachM5nster]

man that really sucks!

but i cant imagine myself modifying and boosting a motor that was throwing codes..

im not beating you up but "what were u thinking" id have to get sorted first, esp with an A/F code

[Monteblueem5]

It’s funny you say that because I’ve been kicking my self I have some really fast
Cars I don’t know why I didnt check my afr to see but according to my tech that’s not what happen the timing skipped and valves came crashing down
On the pistons it was a shit show the block is open on one side I have a 997 turbo making 1280whp on E85 I mean it’s built but still I know when shit don’t
Feel right I come off the Throttle so I don’t know what happen here

[Dwaynos]

A tune cannot be the cause of the timing skipping. It looks like a coincidence that you tuned the car the night before. BM3 is not to blame here.

So you've had some feedback from the shop? Sounds like they pulled a head and found all of the valves bent on one/both sides? If the timing was set incorrectly from day one, you would be down on power and it would feel weird in addition to the lean codes, so it seems that wasn't the case based on what you've told us so far.

[Monteblueem5]

Come to think of it did feel down on power now that I am putting 2 together

[TLK]

Lean mixture is bad news especially on turbo cars, you get detonation. Knock sensors, o2 sensors and a good DME can keep you going for a while but you really have to get that sorted out as soon as it appears.

If BM3 tune leaned out the mixture even further than you had just prior, that could have been the trigger. But may have just going to happen anyway given time.

[Monteblueem5]

Just a call from my Sa new motor on the way

[carlitosgomesm5]

That's great news, good luck with the replacement and hope the shop does a good job.

Damn that is awesome news! GL with the new engine!

[technician117]

Great to hear! Did they confirm any thoughts on what caused the problem?

[Monteblueem5]

The tech thinks it jumped timing

[M5Rick]

Do you know if the timing chain was the cause, that is the chief suspect if it was skipped timing.We read of engine failures but on some the exact causes are sketchy.
