Title: Ttrs lpfp problems?
Post by: Pikey Motorsports on April 11, 2014, 10:21:00 pm
Anyone getting any problems with there's? I have been having probs with my car cutting out under full power in 5th and 6th and belive it maybe the cause of the pump

Yes it can happen.  It can cause the controller to overheat then shut down, causing the cuts.  With a map more suited to your build, and getting rid of the sh*t RS4 injectors then you should be fine.

I've not had an issue like yours but on two occasions so far (over a 4 month period) I've noted this fault code. I had no CEL and the car has always performed well.

012555 - Low Pressure Fuel regulation
               P310B - 008 - Fuel Pressure Outside Specification - Intermittent
             Freeze Frame:
                    Fault Status: 00101000
                    Fault Priority: 0
                    Fault Frequency: 1
                    Reset counter: 255
                    Mileage: 47878 km
                    Time Indication: 0
                    Date: 2000.00.00
                    Time: 08:56:04

             Freeze Frame:
                    RPM: 765 /min
                    Load: 18.0 %
                    Speed: 0.0 km/h
                    Temperature: 91.0°C

                    Absolute Pres.: 980.0 mbar
                    Voltage: 13.843 V

The second occasion happened even after I changed the low fuel pressure sensor.
Have you scanned for a fault code and done  a basic setting for the pump?

Been wondering what it is and something suddenly just popped up whats pointed me to the problem!

Was something what needed sorting but didn't bother to much at only high speed so wasn't on the top of the to sort list...
See apr have removed it from there kit!

Will a ttrs controller fix it also?

That code is normal.  Map spec is different to what the pump delivers.  Just need the specs broadening in the map.

Seem to recall that with the ttrs controller you lose the pump priming function when you open the drivers door.

Thanks for that Alex.
It may be coincidence but I also noticed on each occasion prior to scanning the car my polar readout showed 0 bar for both lpfp and fuel rail pressure.

S3 injectors flow more and spray better than RS4 injectors.  Always have done.  Ditch the Revo map and go to Niki.  The big turbo maps were designed around ATP cast manifolds and GT series turbos.  Done about 5 years ago and things have moved on loads since then.  There is just no need for them to revisit them at the moment. I'm sure they will once they start doing their own bt kits.

Rs4 injectors were and are only used on US based maps as they were all that was available until the TTS was launched there.

I've just ordered some 155 bar return valves for the two Nortech kits I'm doing, and for my build. This should give enough fueling hopefully before needing anything else.  So many cool things that Niki will be working into these new maps.

Is there any proof anywhere the s3 injectors flow more? There's so many mixed opinions on that?

Have you been told that recently about the BT maps? I have been told there new?

I have had going to niki in my mind before, but the car does drive great and makes good power and curve hmm it's a big decision
Title: Re: Ttrs lpfp problems?
Post by: vRSAlex on April 12, 2014, 08:09:07 am
I believe the bt maps are still the same ones from when jonnyc had them.  May have had slight tweaks over the years.  Speak to Kev direct and ask him.

I have a K1 being mapped by Niki at the start of map using the Nortech kit.  Stock engine, but things like a hard cut rev limit will be added, gear based boost, pops and bangs like the rs focus and a mild launch control.  All using the stock n75 valve.  Using boost controllers is just a way of working around a map that isn't specific for a car.

I will try and find the vid showing the S3 injectors flowing more than the RS4 ones. There is also a TTS out there running 600bhp on S3 injectors.

They key is the fuel pressure, like you said Alex, with a 155FPRV and a good pump (LOBA or APR) you're able to run and hold massive pressures!
Title: Re: Ttrs lpfp problems?
Post by: Pikey Motorsports on April 12, 2014, 11:48:56 am
I may change in the future Alex.. But will probably stay where I am at the moment.. Us there any solution to sorting the lpfp from overheating?
Title: Re: Ttrs lpfp problems?
Post by: Hurdy on April 12, 2014, 12:53:39 pm
The Uprated LPFP can overheat and APR say it is due to the difference in the wiring between the VW's and the TTRS/RS3. I haven't had any issues....so far and ran the R at Marham last year with the RS3 LPFP up to its top speed over and over again with no issues or codes.

The RS4 injectors are my only option with GIAC at the moment, but things change.  :wink:

Alex is right up to a point about using a boost controller, but you'll struggle to make the same top end power with a lower boosted turbo. N75 is limited for boost recognition and if you want to run 2+ bar of boost then you'll need a controller and then tune for it accordingly.

Not true on the boost pressure.  You could run 100000000 bar of boost, but the stock MAP sensor needs some trick calibration, or run a 4 bar sensor.

GIAC = American, so they say RS4 FTMFW Yo!  :laugh:

Believe they can cause continuous running without the car running.  There is a good thread on Vortex somewhere.  GolfRS is the thread starter.

Interesting......i thought the general idea was that the s3 maxed out around 420-430...im sure id read that on here a few times,so what is the limiting factor to go more on say a stage 2+ car,the turbo?..

So does the ttrs lpfp actually do anything beneficial??
Title: Re: Ttrs lpfp problems?
Post by: Pikey Motorsports on April 12, 2014, 05:29:38 pm
Had a look at that link Alex? But it sounds like its not to much of a big deal the pump running for a few minutes after? And the lpfp will prime by key with the controller?
Title: Re: Ttrs lpfp problems?
Post by: Tfsi_Mike on April 12, 2014, 07:41:50 pm

Stage 2+ is a fairly modest state of tune by recent standards.

I fitted the lpfp as I knew it would do the same job as my old one just with a much lower duty cycle.
Meaning it's not under stress when I'm giving the car beans on a track day.

My 2nd reason was future proofing for a BT setup that I one day may afford

Post by: mk_boy85 on April 20, 2014, 02:19:32 pm
Thinking about it it's a simple fact starring us in the face. An s3 injector stock runs 265bhp/4 =66.25 per cyclinder and rs4 is 420/8=52.5 per cyclinder and with them not having the perfect flow either it seems that the s3 is a better option.

Post by: vRSAlex on April 20, 2014, 08:27:42 pm
The 'APR' Walbro 255 pump is only around 85 quid. So I guess the cost is in the controller and fittings.

I rigged up a Bosch 044 pump in a big turbo Xbow around 5 years back in the factory basket, but got rid of the oem fuel pump controller for a simpler relay system. Never had any issues with that setup even on slicks.

I'm not sure how the APR system will be for the fuel return, and if it will still overheat the stock controller over long high speed runs.
Title: Re: Ttrs lpfp problems?
Post by: Hurdy on April 20, 2014, 09:20:56 pm
I spoke to Guy Harding about this issue. His R runs an inline auxhiliary pump with the OEM intank pump. No issues at 600+ bhp. I'd say the pre runner to APRs solution.
