Audi TTRS Intank fuel pump wiring mod
« on: April 16, 2015, 12:58:11 pm »
Hi does anyone have a link or any information to help me complete this wiring mod ?
I heard because of the starting amps on a ttrs in tank pump it overheats the fuel controller and causes fuel cut one you go throught the gears at wot.
Apparently there is a wiring mod that will prevent this .
any help please ?

@basman
Dont be silly.
They need the feed bypassed for when on wot somehow.
You would have to run a seperate feed.
The ttrs pump draws over double the current over heating the fuel control unit

I'm currently getting quite bad fuel cut at higher revs, already replaced hpfp for an autotech one, changed the fuel filter and changed the lpfp for another used one. Did some logging on VCDS and the fuel pump struggles at higher revs and doesn't maintain 6 bar of pressure (which I believe is what it should be). Was going to get an rs3/ttrs lpfp but now it looks a bit more complicated than that...

I thought the (standard) pump was variable pressure, 4 - 6 bar?  So long as it doesn't fall below 4, it should be OK.

Well it was reaching 100% duty cycle and 4bar when I'm reaching higher revs which then results in fuel cuts for me.

Rs3 control harness fixes it apparently it's the easy option but expensive
