bootmod3 Stage 2 93 octane OTS map - dyno - 663whp / 666wtq

Any chance you could do a run limited to 600lbft wheel torque? I'm curious to see if the HPFP can keep its pressure at 600lbft across the range.

Throttle starts to close at 2800rpm while the HPFP is still on target for another 1000rpm. HPFP only begins to drop at 3900rpm which if you compare to the dyno graph is on its way and getting close to peak torque. HPFP pressure bottoms out at 5k which given the dyno graph is the point where torque is highest for a given RPM and there's most fuel demand from the HPFP. The DME has throttle wide open already though 800rpm before that, at 4400, where was the DME to protect it with throttle if throttle was part of that protection strategy?

Throttle isn't part of the fuel pressure protection strategy as throttle would've been closed throughout the HPFP drop, it would not open as it was dropping if that were the case. Throttle is a boost control component.

HPFP starts to climb back up past about 5300rpm as torque starts to drop off eventually managing to keep up with fuel demand as we're unable to keep torque flat to redline at this torque level on these turbos. At the same time boost is dropping off towards redline so some of that torque could potentially be lifted towards redline as well but I suspect we'd just see the HPFP not recover longer than here, or go further south.

Question I'll leave you with, why are people adding meth when pushing power on this motor, especially in midrange, if we might have considerably more room to go in the OEM fuel system? How many dynos on straight race gas without supplementing with meth have you seen where someone pushed far higher than say 700wtq in midrange with stock or upgraded turbos? If you know of anyone I'd love to see some datalogs with dyno graphs. There's considerable midrange power/torque left on the table even on stock turbos with appropriate octane.

We're on the same team here, just trying to get the most power out of these beasts so the more factual data is posted the better the discussion. Cheers

It depends on what you are hitting. It could be a lambda limitation, it could be the torque to fuel table is not calibrated in the region you are reaching, it could be hitting an airflow limitation on the amount of pedal, it could be something as simple as the table axis controlling air/fuel/boost/spark/etc only go to a specified amount in Nm. It could be anything hence why I suggested there should be more investigation into the reason.

In my experience, fuel limitations occur at some RPM and flatline, not fall and then recover if it was a hardware limitation. You get to the point of max pressure and the pump would supply what it could. That dropoff of fuel pressure and throttle looks controlled by the ECU. Hence why I call the HPFP limitation not plausible at this time.

I'll answer your question. The aftermarket tuners usually are only making changes to part of the ECU to create more power. They are not usually adjusting all the tables for complete functionality as the time and reverse engineering of all the tables are very expensive. Meth is just a band-aid until someone investigates more and determines why the fuel reduction/dropout is happening.

The HPFP pressure may peak and then drop if the flow capacity is exceeded by the flow of the injectors at full duty cycle.

Can HCP custom tune once Bootmod3 is set up?

And how much is it?

Car: M6
Mods: Downpipes, bootmod3 OTS Stage 2 93 octane map
Octane: pump 93 octane (98RON)

Boost on this run hit 24psi down low in one spot but levelled off to 23psi by ~5800rpm, 21psi at 6600rpm and 19.5psi at redline.

One item to point out, at this power level blending in ethanol is not a good idea as you can see in the bm3 log posted below that the HPFP (high pressure fuel pump) is falling under target to 1600psi from the targeted 2900psi. If you've ever dealt with misfires on your S63tu when pushing power, and not using meth or secondary PI injection to supplement and help the fuel system, then we suggest dataloging and paying attention to your HPFP pressure. Midrange power/torque we feel is already maxed out due to where the HPFP is sitting unless we lean it out a bit to 5500rpm and to go higher in that area you'll need meth which is easiest to install or a PI kit that we don't think exists for the S63tu today yet.

This is the current state of our OTS Stage 2 93 octane map. We're looking to get a bit more dyno runs in as its very likely there's a few more reliable ponies in there at 6k rpm. Let us know if any questions at all.

What numbers is the stage 1 putting down, if one is looking to preserve clutches?

Clutches start to slip if you go much past 650wtq. Stage 1 on 93 typically is around 60-80whp above stock baseline numbers. On a Dynojet roughly around 620wtq.

Perfect. Can DMEs be sent directly to you, or does one have to go through one of your vendors? Also, please keep us updated on the new features of BM3. I see a lot of love for the F80 platform, but not so much info here. Thanks.

You'll be in good hands bro

At those figures do you see the HPFP drop in pressure?

Yes absolutely, you can send it to us as well as any of our authorized dealers.

Everything we do on the F80/F30/F87 front with bootmod3 applies to the F1x as well. The only exception being flashing the transmission which at this time is available for the M2/M3/M4 only. Any questions at all feel free to drop us a line.

Our OTS maps are built in a way that doesn't make the HPFP drops impact performance or reliability in any way.

What does your transmission flash do for those cars?

Maximizes line pressure, smooths out up/down shifts and with the latest update it also makes D1 mode on the S55 seem more efficient with early upshifts

Awesome. Thank you for the link. Any idea if / when this might become available for F series M5/6?

Is the DCT in the M5 the same as the one in the M4 I wonder? Hmm..

To my knowledge it is. My BMW indy mechanic who owns an M3 wondered why the clutch clamping force adjustment wasn't available on the M5 as it is on the F80 platform.

I think it's because the m5 comes with higher clamping force due to the weight.

I have a question for you folks. I like how this capability comes with an ots tune, datalogging, and the ability to do your own tuning. In Hawaii we have 92, which is right inbetween the 2 types of ots tunes offered so the ability to tune locally to 92 is a plus. My question is concerning these two features:

1. Top speed limiter removed
2. Cold start delete with check engine light for no cats removed

I understand you can get them on the ots tune. My question is do they transfer over to a custom tune? Say if I have a custom tune done here to my car will I still have cold start delete with check engine light for no cats and top speed limiter removed?

When you go in for DME unlock the file read out as your backup will be whatever tune you've got currently on the car. You'll activate with that file and it'll become your 'stock' tune in the app. Not stock obviously but we consider it your original pre-bm3 software you started out with and you can switch to it at any time if you like or need be. In most cases by far cars coming in are on the stock software.

Vmax is part of all our OTS maps. Cold start delete and cat efficiency monitor removal for decat downpipes are part of our Stage 2 OTS map.

Hi there, i am at 3500ft altitude,

I am running 2014 M5 competition package, stock, jb4+bcm/91octane/100%meth at 2000ml/min running toyo r888r.

I logged my car with map7(25psi peak)with 3500 feet altitude vs 0 feet altitude in the same day, the results are attached.

at 3500 feet (boost drops as rpm increases)


at 0 feet (boost are on target)


With bootmod3 may i keep the boost for not dropping too much near redline as in 0feet?
