N249 bypass

[footlong]

I've done it an noticed a masdsive difference. Namely my peak boost pressure pressure is now 5psi. Limp mode.

Thanks, but no thanks.

Youve done something wrong then mate

Check your black and white check valve is in the right way round first!

Might help if you post a couple of pictures of how youve done it so we can maybe identify the problem aswell

Not so good,

as pidge says post pictures of what youve done.

What exactly do you mean by that?

Maybe something is wrong somewhere. You checked the massive N249 thread????

 

[footlong]

No, done everything right. i think it is caused by boost spikes. runs ok, dv sounds better, off boost driving is smoother, but occaisionally i get a limp mode after a "good push".

I'm thinkin a map will get this sorted.

what did it used to boost?

 

[footlong]

10-11psi. still seems to be around the same peak but i get an occasional limp.
Bloody cars.

Standard mapping only boosts to 8psi?

 

[footlong]

It's a cupra R mate.

Overboost on a standar map (cupra r) thats all, if you were remapped you probably wouldnt get it. I've never hit limp mode for overboost since i've had the car.

 

[Pidge]

Thinking about it Willz might have been hitting limp mode aswell, Cupra R making ~5-7psi and turbo having to work extremely hard (very hot after only 2 mins!).

And he did have a fault code for overboost aswell!

Although it did have a really nasty misfire between 4-5k rpm

 

[wilz]

Hopefully some one can clear this up for me,

Lambda sensor ordered aswell so will see if that cures the misfire.
