Pfc With No Boost Controller

[rtune]

I was at my local tuner shop today and saw an R34 with (so far) no gearbox.

engine had blown up because owner didn't know it was boosting to 2 bar..

tuner said that another shop and put in a pfc with no attention to a boost controller

and sent him out with a tune, and the dash only showed 1.1 or whatever, but

it was over-boosting and .. bang ..

his bill is going to be in the teens for the engine, and more for the rest ..

Does that sound ridiculous?

totally amazing

How isnt the tuning shop liable for the damage???

Sounds very ridiculous.

How a car overboosts is beyond me.

It runs to the actuator, and if tuned/dyno'd properly they would see how much boost it was making. It doesn't just change like the wind.

And if the dash was showing 1.1 (im assuming aftermarket gauge?) then how its reaching 2bar is yet another mystery

well it was an R34 so it has an MFD and unless the MFD vacuum hose is buggered it should show minimum

boost but what is the maximum it can show? Does regular MFD have a lower limit than MFD v2 (which is 2 bar).

well you didnt say GTR so i took off a cluster gauge type scenario

Either way the dyno operator would know where boost was set

then if there was knock (which youd imagine there would be) the check engine light should have been going nuts.
