Default Golf r mk7 down pipe - 12-28-2018, 02:59 PM

Hi
I'm looking to buy a down pipe, but I do not know if I take one with a cated or not.
What do you think? Catted or not? What the gain?
Can it help to make power with a golf r with a down pipe?(with the Jb4)
and will it affect consumption or with the jb4 we are able to optimize everything.
Sorry lots of question 😂
Thanks for your help
Sorry for my bad english iím a french from Montrťal

We have seen similar gains on catted or non. Just be sure that its legal to swop those out in the Country you from.
Consumption shouldnt be affected.

You can set the Future use D value to 90 and it will autoclear faults. It has a negative in that if it clears the fault it will disable the cruise control if done whilst you using it till the next restart.
You might also want to look at a suitable O2 spacer to decrease frequency of the fault.

It depends how good the traction is which is relative to the street conditions and tires you using. Most guys lower the boost to around 2psi add over stock so the launches are more consistent.
If you running map 1 or 2 just punch in max boost 1st value to 2. If you in map 6 with high absolute values around 17 works as a value.

If its stored numerous times the car needs to do a drive cycle before it will clear.

hi George after some test to try to run my down pipe properly with jb4, I always have the error code epc, to lean or to rich, with use of o2 spacer. I tried several o2 space without real change. I really think the product is fantastic but it does not seem to work well with a down pipe. There must have a way to make a fix on it?
Or i will just change my setup for something more adapted for the jb4

Without JB4 you don't get this errors? I had on my old TT 2.0TFSI down pipe with sport catalyst and it throw errors constantly, Im try spacers and didn't help, so only option has been remap(they change only one byte in code to disable checking) and never get that CEL back... Now on cupra with HJS down pipe with sport catalyst I also don't get CEL but is probably one of most expensive down pipe on market...

There are o2 spacers and there are o2 spacers, I was getting epc light every 2nd drive cycle, until I fitted a good quality o2 spacer. You can't blame the JB4 for the epc light, when it is your down pipe causing the light to come on. Try unpluging the jb4 and see if you still get an epc light. simple.

Wait hummm did i blame the jb4 for the epc light humm i don’t think so.
I only say for what i have tested it not a good combination for me! i think it better to go with a frontmount and a meth kit with a jb4 it’s a better combination.
yes I have $ 400 of o2 spacer good or poor quality, for 1 month I test several combination without success.
And yes i try with and without the jb4, and yes it’s still come up for a simple fac it not changing partition in the ecu it’s just changing some signal.
And yes with some combination of spacer the epc light never come up, but the check engine yes.
My question is only if he know something or if it a try and see.
I don’t want to go with a flash i want to go all out with the jb4 and it potential to max it out.
Its not my first project but with a piggyback yes, so i’m testing it.
And masher55 what is the one you use?
And sorry if some of you thinks i was bashing the product i’m just not the best in english and Google traduction is not the best tools ahha
I really like it, its the reason why my golf r is not with a flash.

I know in some markets they use a straight O2 Mini *** device that seems to work.

Dgolfrmk7, after trying several spacers, I got one from a local company,(South Africa) Strada Performance, which worked great. No issues since.
