Hi I am James Stuarts friend and former co worker Trevor I got a T shirt from you did some work on the 3RS and 3S was not the one who ripped it down the lane ! I am a paint correction,polisher . I am so proud to have been able to help in the small way I have I love your content .I have and currently own a 1985 Jetta with a 2.8 vr6 a little heavy ,and a 1967 VW beetle highly modified for speed and handling . I thought the B5 was a daily driver but I see you like me can not keep it stock. Love 😊U keep moving forward only faster Your friend and subscriber Trevor
I realize that last week running e40 for the first time maxed out the hpfp at 6k rmp I got a CEL for low fuel pressure, older pumps don’t like higher ethanol. This video is just what I been dealing all week lol if I find the issue with this pumps I will let u know . This Cars start pulling a lot of timing when you running out of fuel . So make sure you don’t melt your cylinders . . Awesome video like always , probably next is making sure your injectors have the correct flow .
Cool video. Enjoyed seeing how to somewhat read the logs. It would be cool to watch a video that shows us how to read logs and what to watch for and stuff... 🤔 lol
Did you replaced the hpfp cam follower when you did the upgrade? I noticed when I did my pump that the cam follower was in pretty bad shape at 85k. Just a thought.
I'm always concerned about the plug gap being too large and the boost blowing out the spark. But plugs are new so idk. Maybe tighten up the gap a bit anyway
Which spark plugs and gap are you running? I am running BKR8EIX at 0.026-28 gap with stage 2 single pulley, it cleaned up my logs compared to the stock plugs at stock gap.
Octane booster isn't good for your car. It corrodes your spark plugs. With the perfect blend of ethanol and pump gas I was seeing no ignition correction.
@@VancityAudi I wonder if you don't have valve float? 3rd is the only gear running out to 7450ish rpm. Very interesting issue and thanks for sharing. Hope you get it sorted.
Its interesting that you say the LPFP should be around 4800 hpa. That's where mine is while I'm cruising. It tops out at 6k + when I'm at WOT on a E40 blend. 4800 still seems low to me.
My money is that it is something with the IE tune. If not there it is a issue with fuel injectors. Likely best to take them out and get them flow tested and cleaned. Another thought is that the higher Ethanol could have loosen some crap in the fuel system causing a clog at any point in the fuel system.
This has absolutely nothing to do with the tune, lol. It is a hardware based issue. We have continued to dig in and have found other issues already which will be shared in future videos.
Hey Adam you should do a test on the new 93 shell that’s starting to pop up in metro Vancouver. Ive heard people are seeing great results and maybe this might be the one fuel option that works for people here without running corn juice(or use as much).
You're now the 438th person to tell me that, lol. Find someone else to pay for all of the fuel and the dyno time and I'd be more than happy to provide the testing and video for everyone.
@@dirk5950 my apologies if that is the same thing, lol. As much as I know a bit, I'm still learning other terms. The "HPFP actual hpa" improved significantly as well after we replaced the pump.
@@VancityAudi yeah, would be surprised you could see eff. volume but not pressure. that would be odd. sheet, im still learning the mk7 golf platform years later. all the softwares reporting things in hpa, or millibar or psi and not being standardized is pretty annoying, lol. is ambient pressure included in this value or not? lol. yeah, always learning. it's fun though!

Thanks for the work you put in on the RS3. I appreciate the support on the build. Thank you for also supporting the channel.

I'm dual pulley on 93 and got low fuel pressure with ie hpfp hoping logs show my low pressure pump taking a shit
The good ol balance of too little or too much ethanol... I fight the same on the B9 haha. Fingers crossed you find a solution! Great content
Thank you.
did this job at around 180.000km helped me more at lowrev accel
On a side note, have you done any maintenance on your S4 injectors?
No
Do you ever go into limp mode like a EPC light pop on
No, never

Thank you for the suggestion, but we figured out the issue in the next video
@@VancityAudi Nice! Look forward to seeing it.

We already tried that and it didn't work. We've since figured out the issue and I'll go through it in the next video.
@@VancityAudi oh that's great, look forward to that
Which spark plugs and gap are you running? I am running BKR8EIX at 0.026-28 gap with stage 2 single pulley, it cleaned up my logs compared to the stock plugs at stock gap.
During this video I was running the Brisk DR12S, but since then I have changed to the BKR9EIX at a 0.22 gap.
May be a dumb question, but is there a reason you don’t add octane booster for timing pull?
Octane booster isn't good for your car. It corrodes your spark plugs. With the perfect blend of ethanol and pump gas I was seeing no ignition correction.
@@VancityAudi interesting, never knew that. I don’t remember seeing if you had to change your lines out for ethanol or just D the ethanol meter
@@bagelbandit6076 you need to upgrade your HPFP to run an E40 tune. That's it. th-cam.com/video/QZdhAsxmsBw/w-d-xo.html
@@VancityAudi thanks!!
You consistently have a lpfp pressure drop at the 3-4 shift on both pumps.
That's the way the car has run since I purchased it and have continued to upgrade.

I don't say it should be 4800hpa. I say that the lowest it should get during a WOT pull is 4500hpa.
When was the carbon cleaning last done?
Around 8,000km ago
Thanks for the update. Hope you find the issue before you make it back to the track. Just curious what boost pressure are you seeing during you run.
All of it... 🤣 I see roughly 19.5psi
Is that why I keep losing power when I have at least 150 miles left ?
Possibly. Log your fuel pressure and you will be able to see for certain.
Taking it next level, nice!
Just trying to fix an issue, haha. No next level achieved here.
My money is that it is something with the IE tune. If not there it is a issue with fuel injectors. Likely best to take them out and get them flow tested and cleaned.

everyone blames the tune after switching to 034
Check the fuel filters and for sure new coil packs
The fuel filter is a part of the LPFP from what I understood.

@@VancityAudi this is a douchy reply
@@dvcphotography4564 Take a look and tell me what you think then: th-cam.com/video/vdg8DJmKODs/w-d-xo.html
@@VancityAudi I apologize I didn't realize you've done them before lol
what I really want to know is did you end up finding out the issue with maxing your duty cycle? im having the exact same issues
Which lpfp did you go with?
Bosch OEM
Was that an OEM pump ?
Yes. I never ran an upgraded LPFP on my B8.
Cool video again Adam! What was your rail pressure before and after, did that change?
My logger doesn't record rail pressure, sorry.
@@VancityAudi it's not hpfp actual hpa?
or does it basically just show a 1 the whole log.
@@dirk5950 my apologies if that is the same thing, lol. As much as I know a bit, I'm still learning other terms. The "HPFP actual hpa" improved significantly as well after we replaced the pump.

Should have upgraded and installed an RS7 LPFP, direct fit
There's no need when this was cheaper and works as needed.
@@VancityAudi Its going to act up soon again, they don't perform too good with e40. The Rs7 one is great with e40
@@DavidMoore12345 I don't like your pessimism, lol. Fingers crossed it holds up for me.
That look though lol.
The car says augggggghhhhh
Hpfp was always going to be the more likely culprit. The lpfp is more crucial in terms of flow rather than pressure.
You'd be wrong in this case. The HPFP was working perfectly fine. It was the battery that was the issue: th-cam.com/video/qIbGEbod8Bs/w-d-xo.html
