Most people that have piston problems crack theirs, I melt mine. So, be carefull if you throw a code get it fix Asap.

 

wow..you liquified it!

 

Ouch sorry to see that. Lets not see that on your buildup

 

Damn Scott did your phone get shut off or what?

 

No how come? I have been in and out all day long. But I check for msgs all the time.

 

Well that sucks. Im curious did you have a wideband to watch your afr?

 

No just intense racing tuned PCM.

 

That sucks. Intense said CAI's mess with their tunes.

 

another cooked engine from a 2.5 with no AF monitoring. :/

sry to see that bro....but your askin for trouble with that much modification and no safeguards.

 

I payed the extra for the CAI tune from Intense was kind of POed to find it was still runing lean since their site clams plug and play, but no hurt feeling just more mods.

 

Also the cars been out of commition for about a month finally desided to strip the block today.

 

That sucks, I didnt realize they have an option for that. I got the stage 3 right after they came out and dont think they had that option yet. Im glad I moved on to a custom tune.

 

That's why I want to learn how to tune my own car so I can change tunes with changing weather. I bet you the changing weather had a lot to do with the fact you were getting knock. They should tune the pcm's to be safer instead of getting every hp you can out of the car. My pistons probably already look like that....

 

**** bro that blows! Thats one reason I will not by a pre tuned PCM.

 

Very sorry to hear, at least you can look forward to a forged engine now. Its all you can do when in this position.

I was curious what code you threw, like you said above?

 

Don't forget about the rods..

 

Sorry to hear man .

All you guys with mail order tuned pcms , know what your a/f's are . If it was known this car was that lean , almost every tuner Ive heard of will re-tune for free if you can accurately inform them whats goin on . All cars are different in one aspect or another , theres no such thing a universally perfect tune for everyone . Even with the same combo between cars . I know as fact Intense and Rob both will correct tuning issues free of charge if you can accurately tell them whats going on .

 

what codes did you throw. b4 u blew up.

 

P0171 more pics after I get some more batteries for the camera.
mods: 2.5 pulley, intense pcm, autolite copper plugs gaped at .35", siemen 60 injectors, injen cai, 93 octane fuel, 22 or 23 psi (gauge didn't go as far as the needle did).

 

The code would come and go, it didn't know what it wanted. 2 be lean, or not 2 be lean that was the question, and the answer was 2 melt.

 

Did u verify the injector for the bad cylinder was good ?

 

Haven't got that far yet, just got it apart yestarday.

 

Has there been alot of problems with the siemens?

 

I have heard of one problem with a 60lb injector. So you didn't even have an interceptor to watch for knock? Come on man, you gotta at least do that. Protect yourself. All it takes is a bad batch of gas to ruin an injector or allow detonation.

 

No . I have seen instances with all types of injectors that have randomly prematurely failed . Its not a common problem , but it does happen . It may have been "weak" for a period of time causing intermintent code when it strained for fuel when u drove more aggresively than just normal light crusing . Then just quit , and bye bye piston.
