Fabbing the piping so no new pics for a while.
Tearing the old motor apart to see what failed. Ring land destroyed on two cylinders, but the tight clearances kept it from ruining the block. As we suspected, we probably had detonation. Sent from my PG06100 using Tapatalk 2

Did you actually go from fab to destroyed in 1 day?
How did you get from this:

I believe his old ride- Gretchen, was being rebuilt as it had a low cylinder or 2

Same project new base car. He replaced the engine in Gretchen and took ERRY thing off and put it all on the new one. The LFX has the ability to be tuned with other tuners besides Vince at Trifecta. Good luck buddy. The LLT will never be the same thanks to you.

Sorry for the confusion. Here's the back story.
Right before CFest we had an issue with the LLT (broken valve cover and subsequent leak down in two cylinders). Decided to run it anyway and just buy a new motor for a forged build. We suspected it was the tune so we were a bit apprehensive about not being able to at least see the logs going forward. We investigated swapping ECUs and even buying an LFX but it all looked a lot more expensive than just trading the car in. So, we pulled the LLT motor from Gretchen and put the new one we were going to build in her. That car was then traded for the 2012. Before we got to far with this build we wanted to know exactly what failed on the original LLT motor so we could address any weak spots. Here's what we found. About 1/8th of the ringlands on two cylinders broke off. Because the tolerances are so tight on these motors, they stayed in place and the block/heads look fine. That's the bad news. The good news is that these rods are something else...they should take a lot of punishment. The bearing are also tough -- as much as I put that engine through they look brand new. The crank looks fine as well. These are very well built motors, but the Bosch ECU is not as friendly as we would like. So the take away is we are ordering some forged pistons and lowering the compression ratio. That will take about two weeks. After that we should be ready to tune. Hopefully we'll have some numbers early December. Again, sorry for the confusion.

I predict you will have much better results with your new tuner.
