Title: Has anyone changed the LPFP at Stage 2+?
Post by: berg on March 21, 2013, 10:26:18 am
Was talking to Alex about this and considering it. I know people have changed it at WMI stage, stage 3 etc but was wondering if anyone had taken this step at 2+?

Also spoken to Alex as was considering it at STage 2+ as mine makes a squeaky noise not just the priming buzz...

Perhaps a mini GB if the benefits can be quantified at this level of tune?

Changed it to what an upgraded one or just renewed it.

as the new versions seems a bit different to the old ones, l asume it is for the better  :happy2:

yeh i was just going to change it to the newer version. . Should be pretty straightforward  :happy2:

My take on this is a mod should add some tangable benefit.
If your present lpfp is meeting or exceeding the requested vs actual pressure output and also supplies enough petrol to maintain your hpfp fuel rail pressure then the mod would be a pointless expenditure.

I think my lpfp needs done as top range it feels like there is a fuel cut for a split second every so often, Still need to log is and see what is going on  :happy2:

i have read about a few failing?

Personally i think there is benefit to changing a part that could potentially fail as the miles pile on, maybe to an updated part.

What options are there for aftermarket or new oem pumps?

I've fitted RS3 / TTRS LPFP

How easy/hard was that to do matey?  :happy2:

I was under the impression that these literally run from a 12V source and pump at a really low rate to the the engine, ive spoken to a vag master tech who wasn't able to guarantee it but does doubt there is very very very little point in upgrading it, only benefit maybe prime faster slightly but can't see there being an increase in performance from it, it just delivers to the engine and doesnt run under massive pressure like a hpfp,
only way I can think of it is like maybe upgrading your washer pump  :signLOL:
he couldn't guarantee it too me and im no expert but id want too see dyno results and data logs before I buy one....and soon  :laugh: I need a new one

Post by: Tfsi_Mike on March 21, 2013, 08:45:56 pm

I dont expect to see any gains.  Some people have claimed gains. 

I did it because the lpfp works hard to supply the engine, the TTRS pump will be under much less stress which long term for me means reliability. Also future proofs for possible BT plans as it provides lots more headroom  :innocent:

Master tech!  You mean apprentice.

Variable load pump controlled by its own ecu.

All the logs are in my build thread.  Can flow and hold much higher pressure at lower load.  Basically gives the hpfp more help allowing it to work under less strain.  After fitting I noticed more mid range and top end grunt.  Hpfp pressure was also more stable.

might put the ttrs lpfp in then and the apr hpfp at same time and get rid of the autotech internals

All you need is a pump and a blanking plug when running it in a fwd car.   Ive had some cnc plugs made for the job.

Is the TTRS/RS3 lpfp a direct fit into the S3 then Alex?

Here's the deal.  The TTRS pump does not work on all cars that it fits into.

The problem is the pump controller.

The TTRS pump can burn up the pump controller on most models.  So far, only Golf R, some S3's and some SLCR's are verified to work with the standard pump controller.

However, you can buy this and know that it will work no matter what.  :driver:

"Low Pressure Fuel Pump System

The APR Low Pressure Fuel Pump System is a complete, OEM style, PWM controlled drop in fuel pump and controller solution designed to fit cleanly in the OEM location. The upgraded pump provides adequate low-pressure fuel to the APR High Pressure Fuel Pump to support the power levels produced by the APR Stage III Turbocharger System."

Give me a week and I'll have the pricing.  You can buy the entire kit with the intank pump and controller or just the controller separately.

what is the difference, between the 2 pumps

or with just the controller.

If you have an uprated intank pump already like a TTRS one, you can buy just the controller so the TTRS one will work properly.  If you don't have a TTRS one already, you can buy our complete kit.  Our pump does not flow more than a TTRS one and both are plenty for upwards of 600BHP or more.

alex, have you had any issues with oem pump controllers?

I have one in BWA Seat Leon, Golf R and SLCR currently and they seem to be ok so far.  I know the Golf R and SLCR should be good but we've found that in China for example, it won't work on the Golf R's there.

We've done a Scirocco R and it burned up the controller in about 5k miles.

The issues we've seen are that some cars won't even idle correctly immediately after install, some cars will burn up their standard controller in less than 50 miles and others will burn it up in 5k miles.

Instead of playing the game of who has a controller that will work, we decided to make one that we know will work for all.

I have the TTRS in my golf on stock controller, so far no issues related to controller IMO, but are upgrading to the USP intank solution soon  :happy2:

I want a bit more headroom, and i also want to see how much more the USP solution offers compared to the TTRS. I must say that your solution seems well thought out, any insights as to the difference between the controller supplied by you and the stock one that are supposed to fail/fails in certain vehicles?  :drinking:

More headroom than 600BHP of flow?

From what I understand, we've made one that has stronger electrical components that are needed to keep them from burning up.  Which components I do not know.  The uprated intanks draw more current on the controller and the controllers that fail weren't strong enough to cope with the extra current demands.
