Blew my motor yesterday....tuner says AEM wideband 02 sensor flatlined

[cptnsx]

This has become a lively discussion and extremely informative. I have had to set this aside for the last 2 weeks as I took the earlier advise to heart and just "chilled" on this for a while. I am going to try to get the tune file/data logging from the AEM. Is there a member that can objectively evaluate this tune forensically?
I am trying to make a decision on rebuilding and to what extent and most certainly do not want a repeat of this tragedy.

Thanks again for all the support and advise, genuinely appreciated!

I can take a look at it.

RYU I think you were correct when you said it felt like you made a little more power with the water/meth. What actually happens is the water cools the air charge then when the air/fuel ignites since the water can not burn it turns to steam. Since steam has a very large expansion ratio it helps push the piston down with extra force while cleaning your engine at the same time.

I saw a video AEM put out talking about this on their site or YouTube a few months back.

Thanks cptnsx, I am trying to get the tune file, it has been challenging to say the least with the tuner.......many excuses.....no protein. I will let you know as soon as I can get my hands on the file.
I truly appreciate your willingness to help!

Buying a used motor may also be more cost-effective, once you factor in the cost of labor as well as of any parts you'll need. When my engine needed replacing, I estimated the cost both ways, and found it would cost less to replace my engine with a used one than to rebuild it. (Note, in my case, it was a stock engine.) Don't forget to include all the costs when estimating - the cost of parts or the engine, shipping costs (which can be significant for shipping an engine cross-country), and what you may get back if you sell the block or other parts from your blown engine......

Why would anyone want to procure a used motor in an aftermarket forced induction scenario?

The OEM pistons are cast and mine as well be made from peanut brittle.

I don't see it as being cost effective over the long run. Not at all.... unless he is going back to NA.

Trying to get a tune file from a tuner that blew your motor is like trying to extract hen's teeth.
Good luck B.

Shouldn't the tune still be in there though unless altered or cleared?

Maybe he can pull it himself if the tuner didn't try to cover his tracks.

Do you have the car in your possession? If so let me know I can walk you through the process of getting the tune off the EMS.

Ask him for all logs file, I doubt he'll give it to u. Tune file u can get it of Ur ems unless he clear it

Hmmmmm interesting, Thanks E-Nough Logic, I will Try to get to the car and bring a laptop. I decided to go the conservative route and flat bedded the car to Acura of Lynwood today. Their top Tech, John Li is going to quarterback the rebuild, tune etc., to a finished turn key (tuned) car. He is one of the top Acura Techs in the nation and the one who installed the S/C and Laminova and has done so many times. It's about a $10k proposition but I will have an Acura Dealer behind the finished product. I will have the opportunity to change piston compression and add a better clutch (thinking the SOS 375). This will likely take about 2-3 months. If any of you have any suggestions on the parts and or build, I will definitely take them into consideration. Prior to the S/C my car was doing 287rwhp N/A as it had cams, larger TB, headers/exhaust, CT air box Injector Dymamics injectors and AEM ECU. I am hoping for a conservative tune at around 375- 400rwhp.
REALLY Appreciate the attention and input this post has generated.
Kind Regards to all,
