hpfp should never be first option
If you use correct fuel line and clamps along with install injectors correctly I don't see much that could go wrong. MPI comes stock on ROW models, we're just changing the injector size and when it fires.Yea I I guess the assumption here is a big one but my question is assuming everything is installed correctly. You don't have to look too hard to find people having issues with both but troubleshooting and fixing a LPFP / MPI setup seems more of a pain than swapping out a HPFP.
I guess the real question is if LPFP/MPI setups on this platform have gotten to the point where they are relatively trouble free when installed correctly and when not pushed to their limits.
I'm using these guys with their single ear clamps and tool:Right on. Thanks guys.
Fuel lines had not even crossed my mind. I'll do some research on setups and see where we land but the goal is to get this stuff installed this spring
As for LPFP. Go RS3, don't bother swapping a new pump in your existing basket and that'll remove almost all possible issues. Most lpfp problems are install related.
Yes, You need a tune to use it without damaging the pump, controller or both, but it's a plug and play drop in swap.Dumb question but is the RS3 fuel pump direct bolt On?

It's not quite that simple. So the pump and the controller are from the RS3. They're sold separately, and yes, you can source them to use if you'd like to save a few bucks. Though you'll need hardware that is AWD or FWD dependent to make the pump and controller play nice with the MQB.One more time for us noobs. The controller comes with the RS3 pump? So I just need to source am OEM RS3 pump online and it'll be good to go? That's way less expensive than the alternatives.
They don't. They set the cylinder head temperature targets lower, which causes the ECU to run the water pump more aggressively. The oil is cooled by coolant, which then in turns lowers oil temps somewhat.Rando Q: Why do tuners generally set the oil temps lower? I have a guess that the lower baseline temp helps keep components protected as the car is pushed and heated up. But I don’t really know. Just curious.
Neat! ThanksThey don't. They set the cylinder head temperature targets lower, which causes the ECU to run the water pump more aggressively. The oil is cooled by coolant, which then in turns lowers oil temps somewhat.
It's a nice trick for street-driven tuned cars to keep them alive longer.
