Yea, this is the actual result.

When I installed the MST turbo inlet, I did a boost leak test and got nothing.

I believe I did this datalog on the way home (only got 1 run): https://www.bootmod3.net/log?id=5fb8...90c6284ecd351b

Did the dyno on Sunday night.

Isn't that Peak HP number really low for Stage 2? even for a PWG?

Honestly, I have no idea. So I am waiting for other comments to compare.

I was expecting more, maybe around 360whp with around matching torque. But the torque totally surprised me. I thought I had good tires when racing against AWD cars. I just got a lot of torque.

It's strange because the torque looks a little high and HP a little low. Did you not log the dyno run?

Looking at your other log, the rpm of the values makes sense, since 2900 is right when you hit max boost and after 4500 boost is plummeting, so making peak HP right around where HP and TQ cross makes sense. I would need to look at another stock turbo PWG log but your boost does seem to drop pretty dramatically. I know it usually does, just not sure if to the same extent.

Your timing is great. I assume you have high ethanol content because your HPFP is dipping by up to 500psi basically the entire time until boost starts to fall off.

No I didn't. I should have but totally forgot about it till afterwards.

I'm hoping other PWG owners can chime in and give some perspective as I don't know what standard boost drop looks like.

Using your calculator and working with consistent E content for both 91 and E85, I've been doing E30 mix.

I'll do some logs tonight on the way home from work and see how it compares to this log I just posted.

In addition to what you listed to watch, I also pay close attention to knock, HPFP and STFT.

I see it now, thanks for the clarification. I wasn't reading the whole power band, just the rapid uptick on the graph. Appreciate the info! Thanks

Hi guys, so I'm a few days into bootmod stage 1, coming from a BMS Stage 1 and I'm am extremely happy. The fluidity of the power band is phenomenal. I'm surprised at how much quicker the car is. I clocked a 4.4 0-60 off of my OBDII P3 gauge - my question is How fast is thing going to be when I switch to Stage 2?
I'm currently running ER Chargepipe, Turner intake and Megan Supremo exhaust. Waiting on Turner IC and high flow cat to be back in stock to go Stage 2.

With RWD and good tires, you should be able to get very close to 4.0.

With Xdrive and if you launch aggressively, you can probably get into the high 3s.

This might required more than just the ACN or 91 map though; you didnt specify what octane you are running.

I'm on the stage 1 93 Oct. Sorry I see all you guys talking about Oct and I'm just used to 93 here in Florida. I just ditched the RFT's and went to Michelin PS4, grip is fantastic. If I get lower into the 4's I'm going to be a very happy camper!

I'm in Florida too and you need to start adding some E85 if its near you because that makes a huge difference! Just ordered a set of PS4's as well, can't wait to see how much more it will grip!!

That's normal boost drop for a pwg turbo. My boost curve looks similar running bm3 stage 2 e30. I've never dynoed but my car feels faster than 330whp, based off races more than 330whp for sure. I do have access to high quality 93 and e85 though. My bet is a low reading dyno.

PS4 or PS4S? Hopefully the latter as they will provide much more dry grip. Those are what i run.

Thing is, it read 441tq, which definitely doesnt seem low. Torque is what "feels fast"

Oh my car feels fast, and has race against cars over 330whp. But as mention, it's the tq that makes the car feel fast.

And if it is a low reading, I must be making waaaay more torque. I might start a thread and see if other PWG guys have dyno charts.

I should have shopped for a new PS2 during Black Friday but in my opinion, 10-15% is a basic discount and not a huge Black Friday saving. With that being said, I might be shopping for a used one.

Earlier today on facebook I saw a dyno graph of 535i PWG custom stage 2 tune but basic bolt ons, stock turbo, and it touched 377whp on a mustang dyno. 325whp is really low even for a PWG. Maybe the dyno isn't calibrated/set up properly?

Anyways, I just took another quick look through the log. Given that your IATs are over 100F, my main concern with upping E% would be HPFP crash when its cooler outside. Having said that, i think the best approach right now is to get the test kit, test the E%, run your tank very low, then do a target mix of 25% and log that. In the meantime its not necessarily dangerous to run this map or anything. You could also just run the tank low and switch back to a pump gas map, up to you. You could also assuming E10/E85 for pump gas and E85, target a E30 mix based on those concentrations, and log that to see if its too much for the pump to handle. Depends on how patient you are.

Well my E85 pump surprised me. E85 had 87% and the 91 had 6%. Ended up shooting for an E26~27 mix. No hiccups in my pulls on the highway after the fill. And I managed to squeeze in a log at the sketchiest time of day lol!

Here is my previous log with timing corrections as a reference. Estimating I had an E21 mix:

Here is the new log with E26~E27

FYI I definitely felt a bump/small pothole on this latest log haha

Man its crazy how BM3 is overboosting by like 2psi for such a long time. Anyways, your HPFP pressure is dipping quite a bit throughout the entire pull. I would do maybe 0.25 gal less E85 on the next tank, maybe E24. Its not enough to cause fuel trims to go crazy but its quite a bit of dip. Timing looks good until like 5800 then some corrections. You can see the bump when RPM jumps to 6400.

I saw that my timing had improved. Not sure why it corrects at the higher band. But I honestly have no idea how to read the HPFP. I'll have to search around some guides to get a better understanding. This was supposed to be my finished project but now I'm considering the stage 2 Fuel pump.. frustrated lol.

On my first fill I did 3.5 of E85 and 11.4 of 91. But I decided to do a huge pull on and off the highway to fit in another .4 gal of E85 to be as close to E30 as I could. I guess that greedy .4 additive screwed me.

In terms of overboost, whereabouts did this happen? I was told boost can be +/- 2 PSI to be considered "okay"

Thanks again Jeremy

See attached picture below. HPFP is simple, just look at actual versus target. Ideally you want to be right at target. A few hundred PSI might not be a big deal, but once you get below 1500psi actual you can start to run into fuel delivery issues. Your STFTs arent going positive so your fueling is still under control (i.e, its not a "crash").

The overboost isnt a "problem" its the nature of the BM3 maps. It just differs from MHD and other load based tunes where that doesnt happen (and isnt 'allowed' to without the DME intervening).

If you plan to stay stock turbo, stage 1 HPFP would be more than enough. Stage 2 if you want to future proof the car for a turbo upgrade and ethanol map in the future. The good thing is that now even if you get a stage 1, you can run the 2+ map, so you arent doing it just for the take of having enough fuel for this map.

So I got xHP over Black Friday, flashed stage 3 and yesterday noticed in manual Sport mode the shifts are slow, specially from 1st to 2nd gear, big delay. In Sport+ the shifts are pretty good, barely any delay. My stock Sport mode was way aggressive and now it barely touches 5.5k before shifting. Shifts are smooth and fast in auto, but the manual shift delay and slowness in Sport mode is bugging me. Reached out to xHP and this is what they said:

"Make sure your BM3 engine tune does send the true torque values to the transmission, as "bend" torque values are often used, to get around the transmissions factory torque limits. If your tune uses bent torque values, then they should be able top provide a file without the bent values, as manual cars do not need this for example.

You can try stage 1, which does not use the new shift logic for 8HP, if you prefer it more. Otherwise, you can use traction mode to speed up your shift speed, without having to be in Sport mode for example. Jus click your DSC button once."

Anyone using BM3 OTS maps and xHP over here? Could you please confirm if you shift manually in Sport mode(Not Sport +), is there a delay going from 1st to 2nd?

I believe most of bm3 users don't experience this or maybe don't notice it? Feels like I'm missing something or doing something wrong.

There's a fairly good delay in comfort and sport, but I learned to live with it, normally if I want to pass someone or want to actually use the transmission, I just slap it on sport+ or use traction mode and be done with it. It doesn't bother me as much as it does others.
