Un-top you were pushing a bigger than normal turbo to this kit, with out the proper fuel needed to the engines needs.
I have studied your YouTube videos, one can clearly see you sometimes running lean up top. Again in my opinion, but if you had the proper boost cut via ecutek you would have figured to upgrade to more fuel needed to run properly at that boost level.
Remember these engines were not built to with stand these power levels. The key ingredients is necessary for them to last.
Sorry to hear of you're lost. I too am pushing mine's & have saved in case I experienced the same results.
At the end of the day we all love to push the limits.  |
I appreciate the input and I dont know what happened and you could be spot on but I will point a few things out you are wrong on so it can help use all possibly come to a better conclusion on these failures across the board.
I am running ecutek and do have AFR protection and overboost injector cut enabled and configured by seb ( one of the best in the business ).
I also have knock warning turned on and saw it a few times when getting into the throttle in 4 gear a little to soon in the rpm range ( Learning the car )
I am running a Aeromotive 340 pump with 1150cc injectors and a cjm se-1e fuel return system incorporating a flew fuel setup so I believe my fuel is fine.
Lastly the AFR you are seeing are with E85 and are going to be different than you typical 93 octane tune as well as I had a leak in the initial stages and my wideband was off a bit during off throttle after a pull
I am pinning my failure up to a casting defect or existing issue with the cylinder 1 ringland area and of course pushing the limits to 14 PSI for 4 months probably didn't help it. I have seen a few people pushing the BP kit to this level with no issue so I think it was a one off issue in my case. My replacement motor also is seeing closer STFT numbers on bank to bank so I think that tells me the rings were already leaking oil into the cylinder day one of tuning.
