Blown Engine, Tune Caused This!

[sim302]

Had car tuned in Melbourne, it detonated about a week after I had it done. The first tune was fine for a month or so but the second tune after an exhaust change only lasted a week. After the engine rebuild it was ran on another dyno/another tuner and could not do one power run on previouse tune due to detonation. Previouse tuner is aware of this and wont admit mistake claiming ignorance even after evidence is put to him by other expert tuner. Just wondering if anyone has had success in claiming compensation through small claims, fair trading etc? I know its a long shot, but surely they cant get away with it! Also its not the only car that the engine has let go by this tuner in melbourne recently, and other cars are getting around with undesirable tunes.

Any advice or experience is greatly appreciated.

C'mon name the tuner or suburb, you could try fairclaims but have to prove it was there tune that caused it. Keep trying though, if you name the tuner just think of it as community service to stop it happening to someone else.

Sorry to hear about your problem.

It would be helpful to at least mention a suburb so you might be able to stop someone else sharing your experience.

Yeah I can appreciate what your saying, western suburbs.

there can be lot's of causes for blown engine, yes a bad tune is one, but a rebuilt engine to differnt specs will requires a new custom tune to suit, quite possibly the existing tune would not be right as compression would be different cam timing could be different etc, and if you belived the previous tune killed it, why would you bother risking the new engine with this tune.

It was rebuilt to same specs, the previous tune's af ratio's were wrong, too much timing etc.. in the new tuners experience, after the rebuild they run the car up on the dyno with the old tune to see where its at then retune it. The two tuners also talk on a regular basis and all data was shown to this tuner, the stuff up's were outlined.

More details on the tuner, got a name?

[ratter]

are we talking stock or was the original built?

If stock, things vary quite a bit from one motor to another and a rebuilt motor will still vary, if the original was a built motor that had been blueprinted, a identical motor could be built so things are identical, but I doubt that would be the case.

And if stock, why would you build another motor to stock specs in a performance application.

Air fuel ratio can vary quite a bit without doing damage, but yes too much timing can damage things but you would have heard it pinging. Too much cylinder pressure though could damage it though with out too many warning signs except for how hard it was going before it went bang
