To make a long story short, I had a perfectly fine f22c with 24k miles then had a local dyno shop tune it for me, then the next day a ticking noise arose which turned out to be a a severely scored cylinder wall. I know barely anything about tuning but I was wondering if I told someone my setup and sent them my tune if they could tell me if anything is ridiculously wrong with the tune. I would really like to get this guy in trouble because I found out after doing some research this guy blows motors all the time and does nothing about it but at my knowledge of tuning I cant doing anything. I really appreciate any help!

 

What was used to tune, did you check your oil level

 

what do u mean by "what was used to tune"? I have an aem 1052 if thats what ur talking about and yes oil was fine I changed it a day before the tune.

 

I don't see how a bad tune could cause scored cylinders in 1 day. I would expect a bad tune to cause piston, ring, or bearing damage from detonation.

 

yup

 

well I'm not sure what happened first. Top compression ring was cracked in several places but was all still on/in the piston, the edge of the piston (where the side and top meet, on side of scoring) it is rounded like the piston was at an angle and that edge dug in to the cylinder wall, the piston was also crushed a little because I cannot get all of the cracked ring out even with pliers. I can post pics if anyone would like to see

 

pics would help

 

His tune was way wrong. He caused bad detonation to blow up piston rings and smash the piston that badly.

go after him.
