bootmod3 Stage 1 OTS map testing - 93 octane, dyno - 100+whp/wtq over stock baseline

[proTUNING Freaks]

We spent some time on the dyno with the S55 and bootmod3 building out the OTS mapping for 93 octane pump gas. The car is a non-ZCP, stock hardware outside of K&N drop in filters. The car is also still on stock spark plugs with 47k km (~30k miles) on the odometer.

It was ~90F ambient temps, fairly hot and humid and only one fan in the room with really poor airflow across the front of the car. Peak boost on this run is around 20psi in the intake manifold as shown in the datalog, 21psi before the intake manifold at the pre-throttle TMAP sensor.

We were able to add a few degrees of timing over what we had before at full load and found MBT for these boost levels without any significant timing pull. We're targetting a little richer AFR at 12:1 at full load without any noticeable loss in power which is always nice for added cushion in safety especially for pump gas. We've seen others target 12.3-12.4:1 on pump gas tunes out there, not sure why they choose to run leaner as there's no measurable gains from running leaner than 12:1. Our recent throttle management changes are working great and keeping the throttle wide open at 100% throughout the run which keeps airflow uniform as opposed to erratic behaviour that would disrupt airflow and at times cause an onset of timing pull across some cylinders. Keeping it open when required (at full load) is important and as CaryTheLabelGuy alluded to, BMW seems to also have fixed this at the factory with the ZCP software. We haven't yet been able to confirm that as we haven't seen ZCP software just yet but will do soon. They might be doing it very differently though so remains to be seen.

Air to water intercooler does an exceptional job at keeping IATs in check. Had this been an N54 or N55 it would've been suffering due to really poor dyno room airflow conditions and ambients.

Dyno graph attached. The graph is in STD correction as typical for the BMW platform and zero smoothing applied.

We're testing this tune on a DCT S55 this week (this was a 6MT) and we'll also be adding catless downpipes to see where that takes us for Stage 2 on pump gas.

Any questions let us know

Absolutely great power curve. Especially on stock turbos.

[webshellstudios]

waiting patiently for release...

[te37]

Waiting for release. lol

[chewbakam4]

Those are such amazing gains for a stock car on pump gas. I think I'll just be adding downpipes and that'll be plenty for quite a while!

[tsela_f80]

Let see some FBO runs with E30/100+Octane!!!

I need this in my life (Let me be the first in NJ?) haha

[Bmwlmr99]

Nice, ...I'm just looking at reliability also, nice to hear about a rich air to fuel conversation for a change from a tuner....instead of just dyno numbers

[FSociety]

Great work proTUNING Freaks

Could you also show smoothing 5 graph to compare to other STD/Smoothing 5 numbers etc.

Looks good DZenno! Nice and smooth and timing is impressive on pump 93 at these boost pressures, but not too far from the stock BMW timing curve (max timing).

Some use 5 some use 0 out there. We typically don't like to use smoothing these days at all but here it is, gains are roughly equal but smoothing just makes the lines look a little prettier When looking at dynos you really want to ignore the numbers themselves and focus on the delta (before/after tuning).

[V3rbatim]

You made this power with 22.5 psi? Impressive.

Absolutely impressive gains! I'm not sure how you guys are doing it, particularly when other flash tuners are barely gaining 40whp.

Out of curiosity though, any explanation to the power dip from 5500 - 6200rpm even though the car seems to make more power again after 6200?

VF states 60-70whp and 90-100tq from their stage 1...

I believe with 25psi boost? I may be wrong. Still, good gains.

VF and HEX dynos are Uncorrected and are advertising peak gains.

The dyno above is STD Correction and the 100+ WHP/WTQ is for max gains.

VF Engineering said that Hex Stage 1 is 24psi, and Stage 2 is 26psi. I'm not sure where the boost is being measure at but they posted a dyno previously showing the boost curve.

That's great too, I wasn't aware of that as I stopped following their updates after a small incident I experienced with them which put me off at the time they announced their software "re-release". But they might be the only other tuner making that much power on pump gas for an otherwise stock car. In general, all the other flash tuners, ESS, GIAC, Eurocharged, Gintani, Enzo, PP-Performance, Mc-Chip, EVOTech etc are making around 40whp.

[chewbakam4]

Making more power with less boost is why this is even more impressive.

I'm not so certain that the dyno plots above are showing that they are making "more power" with less boost than the HEX Stage 1. When I read the dynos I see far more power under the curve on the HEX Tuning Stage 1 even though there may be slightly less "peak power". HEX definitely shows a wider torque curve and that's what you feel when you drive.

[BMW M4 PWR]

Ummm based on strictly a stage 1 pump fuel tune on essentially a stock car, this PTF dyno graphs clearly shows a FAR superior power gain than a HEX stage 1... and on less boost to boot* ...The difference between an off-the-shelf static flash and a custom tune sir... it's like comparing apples and oranges. The PTF tool is a game changer* That's a given.. And it's only going to get better from here

Are you blind? What's there to be not sure about exactly? Its black and white and the guy above even said 24psi on stage 1 from VF Hex while this is 20-22.5psi.

The other guy that keeps talking crap its not peak gains they posted. They posted max power stock vs. max power on their Stage 1 like everyone does.

PTF, can you see what MAX gains were in your graph as I'm sure along the curve the gains are EVEN higher.

[Fast Intentions]

this is great, im very impressed by these gains, wonder if this tune will be something that i can use and also retain my JB4 for meth control .

Nice to see you here
