Question regarding my RS4 fpv 200 bar frps

[r5gtt]

Would I be able to fit these parts and not map my car for a while or would there be any issues in fuelling?.

Thanks

200bar?

[Dan_FR]

The RS4 valve yes, but do not fit the rail pressure sensor

200bar?

sorry yes the 200 bar one.

The RS4 valve yes, but do not fit the rail pressure sensor

thabks @Dan_FR crappers wanted to fit them all in when I take the front off this weekend but never mind. Can the 200 bar fprs be able to be done at a later date and is it easy enough to do without taking the inlet off?.

Thanks

[Dan_FR]

Never changed one in situ so can't say.

Feel free to check on TFSI Tuning as it may be ok to 'limp' it to R-Tech if driven carefully, but the fuel pressure will end up being a lot higher than the ECU sees/thinks it is. Certainly wouldn't give the car any stick with it fitted until the ECU software is calibrated for it


Why are you changing it anyway!? Aren't you staying K03!? If so then you don't need to change it

I don't know dan thought I'd fit it as the front will be coming off 
you're right about the fuelling so I'll leave that alone 
May still go K04 later on so will keep this safe.
What of the RS4 fpv can I still give my motor some stick without the map. I'm slowly getting it all on for my 2+ map so IC will also be going on once I chop the reinforcement bar to house the IC and still waiting the 90 degree alloy pipes so won't be any time soon. Time isn't on my side and the weather isn't great although it's nice and sunny outside its freezing

Are you sure it's not a 136 bar FRPV?

(...)C. The other thing they do is use the RS4 fuel rail pressure regulating valve. This valve closes at 136 bar, versus our stock PRVs have a 130 bar limit. APR's stage 3 kit replaces this valve with a custom one because at stage 3, you need more fuel. But, at lower stages, will it help? Let's talk about this valve (OEM Audi P/N 079130757).(...)

^^ 200bar is the sensor not the valve

Absolutely fine fitting the RS4 valve, you can fit all of the 2+ bolt ons before mapping without too much worry, just don't go fitting K04 based sensors like the MAP or the rail pressure sensor

Fuel rail pressure sensor my friend and it's the one I was told to get when going K04 by dan for my car to run properly.

thanks ever so much for that Dan much appreciated  I'll get everything fitted bar the two mentioned and if I do go K04 this year then throw them on with my S3 injectors I sold then bought another set

The fuel rail pressure sensor is 200 bar for the K04 engine. You can use one from an Ed. 30, R, S3, etc.. I confused us with the RS4 valve.

haha sorry man 

I've got all the sensors but wasn't sure if I should fit the 200bar rps on but thankfully you guys are here to help as I would have made a big mistake by fitting it on and causing fuel issues 

K04 is something I'm still looking into and wished I hadn't sold my K04 to that clown who damaged it and blamed me. Didn't need the money but wasn't going to go down that route at this time and now thinking doh I should of just done it but the weather and my nerve problem is preventing me from fixing cars
