I'm going stage 2+ tomorrow.

How do I tell from data logging that HPFP is installed correctly?
Which parameters should I be watching out to verify installation correctness? Like should hpfp target be higher? How do I make sure engine is getting more fuel for each combustion?
Attached below is my stage 1 log:
https://www.bootmod3.net/log?id=5ff9...0b4338ff7a3e34

I'm also getting smaller plug gap. Is there a way to verify that from log?

Thank you!

Your going to really feel a big difference from stage 1 stage 2+. Regarding fuel pump, if it's not installed correctly, you should notice right away upon start up, if the car sounds like it's choking or dying.

When viewing the hpfp in the log, you will want to look at hpfp target and actual. Those two numbers should always be close together, it's fine if they deviate 200psi or so, but for our b58's, are target will usually be around 2800psi, you do not want to see actual going down to 2200psi or lower.

With the stage 2+, you shouldn't be concerned with that at all. I only ran into problems when running higher ethanol mixes on stock turbo (e50 or more) and ethanol mixes on current Vargas GC turbo (e40 or more). That's also because I have TU pump, it can't handle too high of an ethanol mix.

Regarding gapped plugs, just keep an eye out on timing corrections. You usually do not want to see -3 degrees of correction throughout cylinder's 1-6.

You should be good though

You should also run E40 to be safe. I verified I had E30 in the tank and was getting a lot of timing pull. Bumped it up to E40 and was fine. Shouldn't have an issue with E40 for any of the upgraded hpfp. I just mix 50% 93 and 50% E85 to get E40 or close enough to it.

you are running E30 map with E40 in the tank? That's considered OK?

[lixiang7349]

Thank you for your help.
I wanted to verify that I am getting a higher pressure by monitoring the parameters. I was just wonder which number(s) should go up so that I have piece of mind that the fuel pressure is actually higher instead of depending on butt-dynoing.

I would recommend targetting just above e30, like e32. Run logs. If they look good, leave it there. If you see timing pull, increase e-content until it smoothes out. Mine works well around E35 so it depends on the quality of your gas.

I believe i responded to you on instagram or facebook, but i'm just going to post my answer here as well. nothing fuel-related will increase or change in your logs once your fuel pump is installed. But if it's not installed properly, you will see dips in fuel pressure.

[enemigo13]

any idea how much load (%) and E mix can support B58TU hpfp? I still not crashed it (~210% request at 5500rpm, actual is probably bit less, diag limit is 191.25, so cannot see bigger values) with ~e30 mix, going e50 probably requires less load (boost)? what max load limit you should set running full e85 with B58TU pump?

my log btw : https://datazap.me/u/enemigo/f30-340...=2-13-17-18-19

no gapping necessary for stage2+ ,

i have stage2+ with e40 blend , it gives me clean logs

https://datazap.me/u/thomas/stg2-hpf...og=0&data=3-20

why would your rail pressure have a higher target when you switch hpfp's ?
that explains to me you dont know how it works .

Are you tuning the car yourself? The fuel pressure will crash around 2500-3500rpms from my experience. This hpfp design makes more pressure the higher the rpms. So on a stock turbo that tapers boost down you won't have issues in the higher rpms. The only reason to go higher than E30-40 is if you are getting timing pulls. Running straight E85 won't benefit anything and you will probably lose low end boost so you don't run out of fuel.

[enemigo13]

yes, myself. with stock hpfp I crashed hpfp at 4000-4500rpm easily requesting 200% load, fuel 98RON.

My car is Running OK after installing the hardware and flashing 91 stage 2+.
What kind of 0 to 60 or quarter mile can I expect from this set up? I have all wheel drive.
2019 M240i xDrive

Who has a 91 stage 2+? Doesn't even make sense, you are out of octane before running out of fuel pressure.

Ok? Are you suggesting E30?

If you have ethanol near you, I would 100% recommend an E30 map, especially with the TU pump. I've been on Stage 2 E30 for awhile now with just sligh rail pressure drop, nothing too severe. I'll be going the TU pump route here shortly.

Yes, that is the only point to have the TU pump.

[enemigo13]

91AKI/95RON is way too less for even stage2, why run stage2+ without octane? it will be heat, not power generating machine

I have an M240i xDrive and I usually run 7.3-7.5 ETs at the 1/8 mile track, and a trap speed of around 95-96 mph. The only two power mods are a MHD E30 ots map (I aways splash a lil extra E in the mix, but nothing over E35) and an AA catless downpipe.

I do run a xHP transmission tune, but I’m still sorting that one out.

Hopefully this will give you an idea for what the regular stage 2 does in the M240, I’m definitely looking foward to your results with the stage 2+

Well I got it because I wanted to run 91 stage2+ map which requires the tu pump and dp. Are you saying I could have run it even without installing tu?

Thank you for your response but why would 91 map that makes less power generate more heat than the E 30 map which makes more power? That seems counterintuitive.
Are you talking about more heat in the turbo or cylinders.

As far as dips in the fuel pressure, what kind of issue would that cause? If your AFR are still on point does a low fuel pressure cause any problems?

[lixiang7349]

Today I finally pull the trigger to get some E85 mix to run E30 OTS map. Tu pump, catted downpipe, new champion plug at .022, kn filter, stage2+.
The car definitely pulls so much stronger. I was able to get the following logs.
What parameters should I watch out for to ensure I'm doing mixes right?

Data logs:

https://www.bootmod3.net/log?id=6003...90c656f5acc372

I decided to shoot for E33 which turned out to be a good idea since I wasted some through spill and not totally emptying the not-well-designed midwest fuel container.

Thank you in advance!

[T_H_O_M_A_S]

why did you gapped the plugs ? because you read somewhere about it ?
