Endgame setup- BW s257sxe

Sounds like a plan, I hope you can get something worked out. I am interested in what the tear down shows. Goodluck

 

Well..endgame setup is exactly what I got I guess [emoji17][emoji17][emoji17]

Cylinders 2 and 3. Pistons are roasted

Wow, kind of reminds me of.

 

I hope you get warranty work on that engine, that is some serious damage for a built turn key engine.

 

Unfortunately, he won't be honoring any type of warranty on it. Even with it only being 8 months old and less than 7k miles. He said he only honors things that are his fault. So I assume he takes the position that this isn't his fault. I can't believe it really. He is offering to help me with labor and that's about it.

So basically he'll warranty whatever he feels like? Did he say what he believes bro hebthat caused the issue?

 

Yeah, it's really unfortunate how it's being handled. I'm responsible for a whole new bottom end in his eyes. The root cause is unknown. Damage like that comes from extreme detonation I would think. Here is the log from that moment the event occurred. It's pretty clean in my opinion. I'm going to pull the di injectors shipped with the motor and get them tested for now.

For the reputation Jordan has, that's extremely disappointing to hear.

 

Are we in agreement that some sort of responsibility on his part is apparent? I'm still going through all the emotions really. It's mine boggling at this point

Tough situation. You'd think if it was blatant assembly error that it might not have lasted 7k miles, but it also seems your tune is proper and has been churning out clean logs. I guess I'd expect a more final determination of the cause before he straight up says you're on your own in regards to the warranty.

 

Yeah that's how I feel about it too. We really won't know until we tear it all down. It's probably won't happen for awhile at this point. Money is so tight for my family being on my income alone the past few months. Wife was checked out and into a mental health center. All while I went to work and cared for our 2yr alone. The one thing I can do now is, get both the PI and DI injectors tested to make sure that wasn't the cause.

Detonation wouldn't be related to the engine build.

 

How long had you been on that tune revision.

 

Only enough time to load it and take logs to send back immediately. Maybe 20-30 miles realistically. I have logs from every revision saved. Ranging from the bnr s4v1 I had previously on 91 to the current s257sxe 91 and e30 tunes.

Could always be a part failure but that would point more tune than build

 

Part failure? As in?

Anything in the fuel delivery system.
Ignition timing

 

Injectors were sent out for testing today.
In my opinion, the logs tell a lot about the fuel delivery system and potential failure. If it was fuel pump related, we would see a lean condition. Bad gas? We would see KR. Being returnless, all that's really left is the injectors sent with the motor (no test/flow data provided) or my brand new PI injectors.

I was able to visually inspect the intake valves. They do not appear bent or damaged. Aside from the usual carbon build up

You said in this post 8th revision trying to get rid of knock. Possibly the damage was already done to the pistons with detonation before the e85 tune.

 

KR during that revision never exceeded 3.0 KR or throughout the whole 91 tune.
