I'd be willing to bet that they didnt install the cams right...Usually they can only be put in the "right" way, but if the sprockets are way off then the valves are going to collide with the pistons. Thats why some stock camshafts have the cam sprocket attached to the camshaft in one piece.

 

so you all think it wasnt the fact that the car may have leaned out too much?...rather that the timing was incorrect?....if AL (dynoflash) could please comment on my theory of what happened that would be helpful being that he tuned my car.

 

i bet they didn't install the cams right either.

 

It is so freaking hard to blow up an engine with the stock ECU, even reflashed. The ECU is really good at keeping things safe.

 

yup too much timing causing detonation would blow up the headgasket or crack a piston before it breaks a con rod and locks the engine. I would pull the head first and be VERY VERY carefull to check if a socket or screw/nut/bolt wasn't in one of the cyl. A foreign objet getting between an open valve and the cyl head will snap the valve head off and destroy the head/piston/rod and sometimes cyl wall and sometimes turbine wheel.

Seems logical to check out mechanical damage first since the parts that were JUST installed could very well be where the issue came from.

 

This definitely sounds like a mechanical issue and not tuning. Did you put in new springs/retainers with the cams? Also, what did Al change your rev limit to? Keep us updated on what you find out.

 

Definitely True. I think it was the cam install.

 

thanks guys..i'm waiting for the diagnosis on monday.....I would be put in quite a predicament if it was the mechanics fault....being that the owner of the shop is one of my best friends....

 

Sorry to hear of your troubles.

From what I gather, you originally got one of my beta tester reflashes back a year ago for a stock evo


Since that time you have made numerous modifications , intake, exhuast, cams etc etc

And. . . you have not yet sent in the ecu to get a retune to match your parts

Is this information correct - or am I missing something ?

 

that information is correct.....i was just about ready to come and see you again for another custom tune.

 

It's very hard to have the piston hit the spark plug directly.

 

There might be your problem

 

The truth is that many people install cams and drive 300 miles to get them tuned with no problems. Except if the smart mechanic pushed the pedal to the metal then he might ran too lean for a min but I don’t see this happening. Anyways, if the cams are installed wrong which I think it's the issue here then your engine will not last at all after the installation.

 

What typically happens is the plug's insulator comes apart, which usually ventilates a piston. It's sometimes difficult to determine exactly what happened without being able to inspect the engine.

 

In this case, you still have a fuel cut which would have activated if they tried to turn up the boost beyond 20 psi

Whle the tune would have been off for your new parts, as Az3ar correctly pointed out dozens and dozens of people have installed those same parts and driven hundreds of miles in some cases to get a custom tune update without incident.

In this case, the most likely cause was a mistake in the cam instllation or some tool or astner being introduced into the fmic pipes

Best of luck resolving this very unpleasant situation
