Blown Engine, Tune Caused This!

[Paulie2256]

Yeah I would be pretty pissed off. Probably more than you are (unless your not showing it)

If the new tuner had a look at the tune and found evidence of mistakes or bad tuning that directly caused the engine failure then I would say name and shame the *beep*.

You should also post up some evidence. It will make things valid.

Insead of the so called naming and shaming, just say the company where you have got your tune done. Theres nothing wrong with that is there?

Also where were you that you had your helmet on? A circuit track perhaps?

There's waaaaaaaaay to many factors to consider before you blame the tune. I'd be looking at mechanical things and variables like fuel first. Then if you have no clues, begin to blame tune. Which it still may be!

Bummer, bugger and . Bigger power is just so easily accessible in 4 valve engines. I can understand the angst.

They can probably handle some more timing than std off boost to sharpen up response. Manufacturers typically take out a bit of timing down low to reduce combustion temperatures, and therefore lessen nitrous oxides. This helps them pass the emissions and drive by noise testing.

But beware.....when modified, some people just don't realise how well these engines breath with the std head. The timing may even/probably will decrease as it comes on boost, even though the revs may have only increased by 2-4oo rpm or so.

On boost, due to more power, they simply need less rate and total timing than a normally aspirated engine. Any turbo/supercharged engine should be considered a variable compression engine.

A good rule of thumb I always use is this;

Fueling and ignition timing follows the airflow curve (and therefore the torque curve) up to peak torque in the low and mid ranges, and then follows rpm to max revs.

I ALWAYS turn the radio/stereo down when I stick it to a modified turbocharged engine. Listen to/for messages from the engine.
