Hi guys, Im thinking to do an HPFP upgrade - but I live in Indonesia where the octane rating is bad and we dont have ethanol at all at gas station.

Im currently running an OTS BM3 91Oct; do you think with an HPFP upgrade the power gain will be worth it if I were to stick to the 91Oct tune?

Any inputs will be greatly appreciate, thanks!!

Not worth it if you only have access to 91.

Have you ever tested octane boosters, such as boostane? I know you run a combination of different fuels

Alright, so I've read through all of this (and likewise have previously posted in the thread).
If I'm on a stock turbo with MHD Stage 2, it sounds like I can upgrade to Dorsch Stage 2 (to later upgrade a turbo in the future) and just select the setting in the MHD app for the Dorsch HPFP) so that the car can run properly. Is that right? Or do I need a completely different tune for this?

T_H_O_M_A_S · 07-04-2021, 12:23 PM

yes and no

Lol, yes to which question? Yes, I just do the selection in the MHD settings and I'm good to go; or Yes to needing a custom tune?

T_H_O_M_A_S · 07-05-2021, 04:59 PM

again yes and no

or
yes you can use the pump if you check the option .
No you dont need a tune to run an aftermarket hpfp .
its just a electronic controlled mechanical device to supply fuel at a certain pressure into the rail .

Does anyone have experience with Deatschwerks DW440 pump?

It's a brushless pump that is advertised as having B58 Supra compatibility. I purchased one and it looks to be the same physical size as the pump and same connector that came in the fuel bucket core that I purchased.

That is not a high pressure fuel pump, that is a secondary/replacement fuel pump to the low pressure one. If you havent done the HPFP or are not running port injection that you have no need to do the LPFP

Thanks for the reply. Sorry I didn't clarify I I have a dorch stage 2 pump and wanted to run full e85. I was just wondering if the stock lpfp would limit me in some way.

If you're on stock turbo than no not yet, but check your logs when under full throttle and high rpm if your fuel pressure on the low side is dropping than yes and upgrade is needed

kern417 · 07-20-2021, 10:44 AM

Rule of thumb is if you don't need port injection then you probably don't need a LPFP. It seems to flow more than a stage 2 pump for most setups.

kern417 · 07-30-2021, 12:38 PM

I made a video discussing why some hpfp upgrades need custom settings. Hope this helps.

Uni-Rapide · 07-31-2021, 05:16 AM

Just wondering, does anybody now the difference between the old and new calibration for the Dorch HPFP in BM3? And when you should use which calibration?
Thanks!

If I remember right old calibration was for aftermarket fuel pump but the new calibration separates stage 1 and stage 2

Found a good price TU pump online so I have been thinking about getting a TU pump upgrade this few days.

1. How is the reliability of the stock HPFP? I can't seem to find much reports of it failing prematurely. I'm curious to see how long they last.

2. I think I wont be running E30 blends anytime soon as my 440i is a daily drive. Will i see much gains with TU pump on MHD stage 2 map?

weehe126 · 09-15-2021, 09:40 AM

You will see no gains by just switching to the TU pump. The pump lets you use E30 which gives the gains.

Thx for reply. Looks like the factory pump are pretty reliable too?

The HPFP is extremely reliable. Not many ways it can fail since it's a mechanical pump. They should last the life of the engine.

You need to flash the stage 2+ map to access the extra hp that's supported by the TU pump. Running the same stage 1/2 map will not net any gains because the pump itself doesn't change anything.
