you need to change the plug also . some soldering is required

The N54 and early N55 pumps are stronger than the standard N55 HDP5. The B58 plunger style pump won't fit to replace those rotary style ones.

The S55 pump is an HDP5 pump. I suspect it's equivalent to the N55 pump, thus the need to use two of them on the S55.

showtime I think you need to order the connector too.

OP, what PSI did you reach with just 93?

Any update on the ethanol too?

i havent had any map updates so far , and as for ethanol ,
i prolly need a map update too . never used it before .
Peter told me to go the E20 route to see how far the pump can go

Will be very interesting to see what power you reach with this pump before fuel becomes a issue, maybe compare pump fuel, E85 and E20

To those who have gone and bought the pump, mind keeping us updated on how this solution works for you? Highly considering this upgrade in the near future.

This is pretty exciting news if this is truly an almost "plug and play" solution. I'm quite surprised no tuning is required for this pump. I know the XDI pumps require some values to be changed in the flash. Awesome work!

seeing as this evo pump is within 1% of the xdi 35 could we install this pump and select xdi35 when using an ots bootmod3 flash?

HDP5 evo running on N55 engine - YouTube

uploaded a movie clip of the evo pump running

the longer wires were just in case i had to swap them , but they will be shortened overtime :D

I highly doubt it, from what i understand the XDI pumps run a different frequency, i could be corrected, the evo pump will plug and play, not sure how the car would feel most probably going to need a custom tune

dont think extra programming is required , when i check rail pressure mean vs req , one follows the other smoothly , been running it for couple of days without any flaw

So I'm guessing this pump works as well on the late 135i/335i E series? The ones that were built after 06/12?

if your car has a plunger style pump , it could very well be

I have an F87 M2 - just a quick question regarding the connector swap. I've attached the only picture I have of the connector that goes to my OEM HPFP. Based on the part number you've provided for the connector you had to swap, it doesn't look different from mine. It looks the exact same actually aside from the wire colors. My OEM wire colors look to be solid white, and blue/orange striped.

I know they're not the greatest photos, but did your OEM connector look completely different from the one you had to swap in? The connected you've recommended looks very similar to my OEM one. Do you mind taking a look at the photo below and confirming as to whether or not I'd need the connector?

Thanks!

for some reason i cant post the datazap links :s
I applaud you and others before you trying different alternatives to increase the performance of their BMW. As others know from different online forums, I’ve done the same. Some hits. Some misses.

While your results are interesting, I see very little actual improvement in the results as the HPFP cannot even hold 2000 PSI. It is struggling to hold that.

My stock F30 N55 HPFP can hold that and more.

As for alternatives, the XDI-35 runs at 2600-2900 PSI and can easily hold 2900PSI. The XDI-60 can run and hold 3500PSI (but the F30 injectors probably won’t like that).

So all in all, I’m not seeing where this is really much of an upgrade. In fact on my car, it would be a downgrade from stock.

If you put it on a physical dyno, you’d see that.

Again, high fives for looking at possibilities. But this seems like a miss to me. XDI far superior performance.

Well i ve got that comment once more from somebody else . in every log i have so far from wegde /MHD , even with the oem and the evo pump , at the beginning of the log , the rail pressure is higher , but tapers to 2050 . in the V1.10 of the app there is also a rail pressure required . the rail pressure mean just seems to follow that . why its only a little over 2000 psi idk ? maybe its tuner related ? . what i do see in those logs , is with the oem pump rail pressure dropped further when hovering around 18 psi , the evo version doenst . 800 psi or 2000 psi is a decent upgrade to me . its only to be seen how far it can be stretched when ,i or others who are willing to try this , going with E20 or more


as far as the connector goes ,it has to do with production dates
If your car was built before March 2014 you may need a new plug.
It was changed around 03/2014

Perhaps your OEM HPFP was old and worn out :

Considering Rail Pressure Request Data is NOT in your OEM Stock log data, one cannot compare.

But again, I am not seeing an improvement based on what I’ve seen on mine and others stock HPFP.

Suspect your number will drop dramatically as more ethanol is added based on the data provided in your files, as it is struggling to hold 2000 PSI on 93.

we'll see it overtime
what i do see in the logs after a shift it crawls back to 2000 where the other wasnt capable . the xdi will get you prolly even higher boost levels i know that too, but at what cost ? if i wanted to get me one i had to pay at least 2500 euros incl taxes and everything , now ive paid less than 200 for this easy fix . i also dont seek 25psi levels or higher . if i get to 20 or 21 psi with e20 its fine

Incorrect.

Itís common for a tuner to target a lower rail pressure when using the oem hpfp, especially when you are on the edge of what it can flow.

You need to factor in load/boost, afr and iatís to get a decent picture of how the hpfp is managing. Just because your oem hpfp held 2600psi doesnít mean itís stronger.

You can quite clearly see the oem hpfp struggling to maintain the requested 2000 psi, after adding the evo hpfp it maintains this without issue. The requested 2000 psi wonít change until the tuner changes this in his tune.

Another source has stated this pump flows 13% more over the oem. Going off of this it isnít as strong as the xdi-35. However that 13% should run some decent numbers on a ps2 and certainly max out the oem turbo. We wonít know for sure until someone tests and tries.

Great work Thomas, for sure this pump is showing an improvement over the oem. As explained above the rail pressure is lowered by the tuner. it will be interesting to see how far the pump can take you.

I noticed you mentioned the connection changes at 2014, do you know if the newer connection is plug and play or is still required to be swapped out?

Cheers.

Sorry Thomas I was referring to the cars with a build date after March 2014. Will this newer style connector fit straight into the the evo hpfp?

normally it should do a quick check on your car's pump to make sure

Great news, makes it even more simple for the newer cars then.

Iíve bought myself a low mileage pump to fit to my M2. Should provide me with enough fuel to max the stock turbo out now 👍🏻
