TU Pump DIY: ruclips.net/video/ealRKi-PTPI/видео.html
You always read my mind. TU gets here Tuesday! Best B58 channel on YT.
I wasn't going to do it if I had to splice my car oem wiring then I found a video somewhere of flipping the plug! And yes loosely attach everything together then torque down together! I had to learn it myself!!!! 💯
Just ordered a tu pump. Thank you for the info on our platform!
Updated DIY coming soon 😬
Can’t wait! Getting ready to order custom trans tuning from watching one of your other videos!
I simply love your channel man. Keep it up
🙏🏾
I got my TU Pump from Puma Speed Performance in the UK brand new for $425.00. I haven't installed it yet. I'm waiting until spring weather gets closer. Then I'll install the pump, CTS catted Downpipe, Remus cat back, and the XHP Tranny tune. 2018 G30 540.
You’re going to have a fun summer.
@@Hockenduke Thank you bro
How much hp you pushing ?
I literally was saying I'm done with upgrades. But with TU pumps prices dropping. I have no choice.
Tbh it's basically an investment idk 🤷🏾♂️
I appreciate you vids man ❤️
Hell yeah good stuff!
Picked mine up 6ish months ago for about $500. Still need to find somewhere i can fully open it up so i can run some logs 😅
Great video!
Can you do a tutorial with the installation method you mention or link to a video where they use this easier way to install it?
i'll be installing one on the 340 and will include that in the video
@@kern417 Great, thanks man!
i like it already
Thank you
Now the TU pump is 250 bucks. For a stock turbo its a steal for stage 2+ e30 or e50
Excellent vid as always, you continue to provide a great service to the B58 community 👍
I have a M140i, currently Stage2, considering going Stage2+ this year.
Are there any benefits of using a Dorch Stage1 over the TU HPFP?
And would the Dorch Stage1 produce a slightly different power/torque curve compared to the TU?
Future plans to perhaps put into consideration of the HPFP choice.....undecided if I will be going Stage3 or not, if I do it would be a smaller hybrid turbo, possibly the LIttco L520.
No real gains from TU to DS1
What is your fuel economy?
Thanks
I really appreciate it man
I have a TU pump ready to fit, but *_I have a question_* ....After a little story/rant sorry:
I previously asked a well regarded BMW/Mini specialist to fit the TU pump during my car's service. He was at the point of bolting it to the head and called me to say he was apprehensive of torquing it down. He reckoned that, because the TU pump has a thicker flat bottomed plate vs the stock pump having a thinner plate and indentations around the bolt holes (to accomodate tall cone shaped o-rings on the gasket), it would require more than 12NM to fully seat the pump in the gasket and be leak free.
As he didn't want to risk stripping the threads, trying to get it to seal, he didn't fit it (even after watching your tutorial vid); proceeded to re-fit the old pump and charge me 2 hours labour on top of my service bill 😡
It was suggested that if there's a TU gasket (which there is) he would be happy to fit the pump with the 'correct' gasket (costing me another 2 hours labour).
As a TU gasket was pennies I bought one, so I could see whether it had the 'all important' thinner o-rings (which it does, they're flat not conical). The issue is: the outer shape is not the same as the gen1 and I think it will be incompatible with my cylinder head. Of course I won't know for sure until the pump is removed again.
As I'm not paying someone to do a job twice, I've decided to fit it myself once I have a day off with nice weather. It's just the 'issue' he raised, is now worrying me the longer I think about it.
What do I do?
Do the original gasket 'cones' compress easily enough so the outer gasket seals up fine at 12NM of torque?
It seems everyone and their gran have fitted these hassle free and I'm the only one stressing out! 😳🙄🤪
Sounds like overreaction. I have just fitted a TU pump and there is plenty of thread engagement, even with the thicker flange. Thread striping aint a problem for sure. Most important thing IMO is to tighten it 90 degrees max per bolt, alternating to not damage the shaft. Acc to ISTA, when working on the fuel system, it is also recommended to cover the ignition coils (remove if necessary), as fuel contamination on the silicone hose can damage them. Just follow Kevin's DIY and send it!
Everybody I know has used the stock gasket. I don't see it being an issue.
@@LuizPauloDT Thanks bud, that's what I thought. Sending it Sunday if the weather is kind to me!
@@kern417 Appreciate the response Kern. 👍I knew he was being over cautious. Great content as usual.
Do you need to add a tune to run the TU pump safely? Not just for power gains, but to just drive.
no bro
i heard you do so the ecu can adjust for the tu pump
Love the content man. Installing my
Tu pump today for my g30. If I stay at mhd hpfp stage 2 93 will I see a decent torque jump while I wait for mhd flex fuel to get here?
you will not
so do i need just the pump or the fuel rail too
You probably never got this question brother, but why does BM3 have a stage 2+ 91 octane whereas MHD only offers a stage 2. One shows huge gain with 91 octane whereas the other doesnt?
There aren't really much gains to be had with 91 so mhd didn't make a tune for the tu pump.
@@kern417 bm3 are basically liars than 😂
Great video buddy! Have a question- actually running mhd stage2 98ron. Is it worth to upgrade pump to TU and go stage2+ while i will be running only 98ron?
Thx for answer ✌🏼
Yes. I Will be posting a video soon with my testing
Trevor is a good guy, but I buy my products through MRM Performance. He has the TU pump for 389.99 and Micheal is a pioneer in the b58 community
Hey Kern, I was looking to get your opinion on whats going on with my 2021 Supra. The only mod I have is a Active Autowerks catless downpipe and am experiencing a decent amount of smoke pouring out of the exhaust at random points usually when the vehicle is about to come to a stop or is at a stop, and the car only has just over 1000 miles on it. Do you think this could be related to the PCV system?
It could be. Do you have any codes or anything? And you're saying the car itself only has a thousand miles, or it's been a thousand miles since you installed the downpipe.
Could just be the downpipe itself. When it reaches those extreme temperatures for the first time, smoke can come out, typically white smoke. After driving it around, the smoke will go away completely
@@kern417 The car only has just over 1000 miles total mileage on it. I for sure have codes for deleting the cat but I have not read them as of yet, I do have access to snap on scan tools though. My though was; I may have revved it a little too hard before getting it tuned and messed up the internal pcv system? I'm not sure what else it could be. Thanks for the insight!
@@dennybrows9916 I have had the pipe on there for a while, it would not produce the large amount I am seeing or at random points. It is most certainly burning oil for whatever reason.
@@fatalmastermind yeah potentially. Thick smoke is usually oil
Great video, can you run this pump on a 2015 435i n55 ewg?
Some people have made it fit on an n55 by modifying the mounting flange.
@@kern417thanks for the help!
Hi mate! Do I have to reset any adaptations after installing TU? Or just install pump and thats it :)
Just install
will you see improved power on stage 2 93, by switching to a TU pump?
i believe it would just be better to flash stage 2+ as all you require for it is the TU pump.
Hey I have a DP+intake and stage 2 on Bm3 tuned. Would I gain any power upgrading my pump to TU pump and sticking with same tune?
No
Do you need to tune the ecu, if you upgrade the fuel pump and the hpfp?
TU HPFP: No
Dorch/Spool: Yes
@kern417 so I got a 2019 440i the basic sport package not the M on my car I want to tune it thinking of going stage 2 do I need a hpfp since I live in California & it's hard to come across 93 or e85 gas can I jus run it on 91 with no hpfp? Thanks for your time & help
watch his video of running E on stock hpfp
What if I run 93 only with a TU pump? Will I see any gains? Compared to the stock pump?
Slightly quicker spool but not necessarily a lot more top end
Does it matter what HPFP I’m running if I have port injection?
The tune will be different if that's what you mean
@kern417 i just ordered the TU pump i believe it comes without a cam follower from my understanding its best if i use the original cam follower and place the new TU pump right on? also would you recommend i use the same gasket from the original pump onto the TU pump?
Just replace the pump. I made a whole DIY explaining the process. The link is in the description
@@kern417 good lookn G 💯
Picked up a used one for 280$ ready to install on my G01 X3. But kind of get stuck cause the hpfp in the G01 is covered by a piece cover and I am still figuring out how to remove it. Searched a lot of tutorial videos but all the F or G chassis 3/440i don’t have a cover over their HPFP.
Thank you for your reply. I have figured it out on a video about installing Dorch HPFP on G30 540i. Just unclip the grommet and move it backwards.
Hey mate have you eventually fit it? I'm trying to fit it today but the TU pump doesn't sit flash the spring session it's slightly longer.😢
@@leonlou3422 yeah. There is a video on installing Dorch stage 2 HPFP on a 540i. The cover is exactly the same as G01 X3. They are just held on to with 2 grommet.
thoughts about putting this pump on an n55 ewg?
requires some modification to fit but some people have done it
Hey kern big fan of channel. I have a 440i gc and I have pure 800. Tu pump , PI , meth , Fbo, stage 3 low pressure fuel pump running on full e. How much power do you think the tu pump could handle before I’d have to swap to a dorch stage 2?
If you have all that it doesn't matter
I have seen some ppl mention they use a filter when switching to an ethanol mix, are you running some type of filter?
The only hpfp upgrade that I know to come with a filter is spool. I don't use one and most people don't.
@@kern417 awesome, thank you!
Hey, I just installed the TU pump and after a couple minutes of idle, i got a code saying it’s running too rich. Does this mean I installed it incorrectly or something else. I’m tuned on Mhd and 91oct
make sure that everything is connected properly. make sure the connector is fully seated etc.
Hey Kern thx for the amazing video! with the tu pump and stage 2+ MHD tune, what e85 mix do you recommend 50/50 with pump gas? If you could please tell me your thoughts for maximum power?
usually e30-e50 just depends.
ruclips.net/video/vKUJGd8-H2Y/видео.html
Ok thx for the reply Kern
Hi did installing the tu pump cause a check engine light to come on or give any problems with smog ? I don’t want to swap it out for emissions
i’m thinking about getting a TU pump so i can jus go stage 2+… if i get one, do i HAVE TO do a e85 mix or can i still run regular pump gas?
@@jscraziii2568 there are pump gas maps for stage 2+. But it can also work with any other stock/stage 1/stage 2 tune.
Hi, I have a TU pump installed on my Gen 1 and intend to install a pure 800 and run only 94 Oct. How much power do you realistically think is left on the table with this setup as opposed to installing a Dorch Stage 2? Thanks
you won't make much more with a dorch on pump gas. the TU is plenty
Thanks
Having a 540xi, if i want to go for stage 2+ with tu pump, what about my transmission? Would it handle the torque?
No doubt
@@colbybalduzzi6667 heard its recommended to keep it under 600nm
600 ft lbs. Closer to 800Nm
I have a 540, I ran the MHD stage 2+ for about 6months without any transmission issues. Now I run a Hybrid and so far all is well. However, I just don’t use launch control.
get xhp
Can a tu pump be fitted to a stock (mppsk) 340i? I know it will provide no gains at this point but I will go stage 2 later on just wondered if it’s ok to fit before tuning or is it best to do at the same time?
Yes
Just a heads up, you will want to go stage 2+ not stage 2 with the TU pump!
Hi for stage 2 is it worth getting tu pump? only for Pump gas?
Only for stage 2+
@@kern417 thx , summer I want to tune it …
If I get the tu pump can I run e40?
Sure
Do you (or anyone else) know if you can fit the B58tu HPFP on a B48? Looking to run higher ethanol content.
yes
I think the b48 comes with a tu pump . I popped the hood on my daily 2021 330i and the pump looked the same , I have not confirmed this though I should have look at the number on it and see if they matched
@@giowilliams7855 you have a B48TU
@@giowilliams7855 I have a 2017 330i (so 1st gen)
If I'm only running 91 pump gas on a gen1 B58 340i with no plans to upgrade from the stock turbo - is there any benefit to upgrading to a TU pump?
Not really
I’ve noticed kern is really short when answering comments. If you’re on MHD you can use the stage 2 hpfp map if you have the TU installed and you would notice a decent power gain. Don’t know why he said you wouldn’t.
Mhd does not have a stage 2 hpfp map for 91 octane. Pay attention to the details.
@@Owen-ww3tr😂 hmmm
Hi, I have a 540i and I recently upgraded it to a stage 1, running 370whp. I also substituted spark plugs to new stock ones and cleaned up fuel injectors. However recently an intermittent failure occurs, mainly after after continuous time of flat out driving, in which the engine fails and the car gets to emergency mode. I still didn’t get to the cause of the issue, but I suspect it may be something related with a hpfp. Do you think upgrading it to a b58tu would make the system safer and avoid potential issues? What else could I do to improve reliability?
you need to diagnose the problem before throwing parts at it. scan for codes. run a log. and go from there.
@@kern417 thx for replying, it has been now a week I left it on a specialist to get me the diagnosis and they still couldn’t find the issue or replicate the failure 😂😂😂😂 I will keep digging it and for sake of curiosity will let you know what was it when we find out
Sorry if this a dumb question. Thinking of getting this upgrade for my M240i. Can someone explain what a HPFP does and if my economy will be reduced by installing one?
Hey kern I have a m240 I’m currently stage 2+ and running a E30 blend on my stock fuel pump I was told that’s the safest blend I can run on stock fuel is it really safe for the car ?
You cannot run stage 2+ on stock fuel pump
@@kern417 sorry not stage 2+ I mean stage 2 with the stock fuel pump
@@irobtheweedmam ok. phew lol. but you can run any ethanol mix with a tune designed for it. if it's an e30 tune then i would only run e30 unless logs indicate otherwise.
@@kern417 it’s not a custom tune I’m still on Ots maps
@@irobtheweedmam depending on your tuner, they offer e30, e50, or even full ots e85 maps. So run whatever the map is designed for. If you're running e30 tune, stick with e30.
