B48-T0 OTS map update is out  - Version 2.0

The new OTS maps have gone through a huge revision this time.

  • CHN91 (Chinese 91) OTS maps have been added for poor fuel quality with lesser ignition timing and slightly less boost pressure over the ACN91 OTS maps.

  • We also added E30 OTS maps for those who'd like some more power on their 4 banger 
  • AGG OTS maps have been optimized for burble so they are really aggressive this time, duration and aggresion have been changed to suit the map name.

  • Drivability overall have been improved, yet with better throttle response. This is done through a different torque strategy compared to previous maps making the car feel more comfortable during slow driving but a beast when going WOT 
Enjoy ! 

Version 2.0, August 8th 2021:

- New torque strategy

- TCU limitation removed

- Improved drivability

June 16, 2021:
bootmod3 CustomROM (MapSwitching,FlexFuel,AntiLag) N55-M2 Engine Support and the New Map Editor - Now Available!

bootmod3 CustomROM Features + New Map Editor + UI Enhancements

June 2, 2021:

B58-T0-C and B58-T0-D OTS map update is out- Version 2.3

The new update utilizes an increase of TCU limitation to the ECU. This allows for more midrange torque combined with a new boost control strategy.
Moreover, the drivability has greatly improved. Casual driving is now totally different and has a stock-like feeling until pedal goes all the way down.
Ignition timing during spool has also been changed allowing for a slightly quicker spool.

Key features:

  • Major improvements on drivability
  • TCU limitation of 550NM has been lifted
  • Boost control has been improved
  • Aggressive OTS map versions now have a more deep burble sound

Minor OTS map update for the B48-F-H (Version 2.1)

The ACN91 octane OTS maps has been updated to provide a more solid and stable OTS map for people who only have access to really poor fuels.

This new set of ACN OTS maps has been tested with a lot of cars all over the world in different altitude, fuels and weather.

Ignition timing targets have been changed to prevent ignition timing corrections, together with a slighly richer air to fuel mixture reducing overall potential knock.

Moreover load and torque structure has been changed to provide a maximum load and torque over a given RPM range.

More updates to come !

November 26, 2020:

B48-F-H OTS map update version 2.0 is now out!

Completely new strategy on the new OTS map has been carried out.

Torque calculation and boost control has been changed.

Ignition timing advanced has been changed as well to minimize ignition timing corrections for all the octanes available.

All this results in a flat torque band giving the user great power towards redline.

Map info:

Version 2.0, November 26 2020:
- New torque structure
- Ignition timing revised
- Boost control revised
- Power increase

July 3, 2020:

S58 OTS map version 2.4 is out!

After gathering tons of datalogging from users across the world, even more improvements were found, applied and tested 

These findings resulted in a smoother boost curve at high engine speed allowing for a more clean ignition timing curve thus more efficient power, especially on stage 1 cars with stock hardware.

Furthermore, burble is now working better for cars with particulate filter (OPF).Version 2.4, July 3 2020:
- Boost taper at high RPM fixed
- Unstable wgdc at high RPM fixed
- Burble activation for OPF cars

May 10, 2020:

B58-G Stage 2+ OTS maps now available!

The stock turbo can flow on the B58, but the limitation is the HPFP, with the B58TU HPFP or Dorch Engineering HPFP you can unleash the true beast of your B58!

Boost pressure is around 20 psi

Required hardware:

- High flow downpipe

- Upgraded fuel pump (Dorch Engineering or B58TU fuel pump)


- OEM BMW B58TU Fuel pump part # 13518631642 - This fuel pump is plug and play, Map Configuration should be left unchanged or set to OEM

- If using the Dorch Fuel pump, Map Configuration for the HPFP should be set to DORCH

We recommend XHP transmission flash to take advantage of the high torque

B58-G OTS map version 2.1 is now available!

Version 2.1, May 10 2020:
- Boost and load control changes

We spent a lot of time on boost and load control on this Version 2.1

This should now be resolved.

That doesn't explain what your tune has to offer to the community. Congrats on the accomplishment though. But you veered of the topic of discussion. What does your tune offer in terms of drivability, fueling trim, overall powerband curve.

"For example. All the tunes out there piggyback or flash for the F10 / N55 have all claimed peak numbers, but only peak numbers and nothing that held across redline. So if my goal was to peak at 350whp, but at 5000 rpm I started dropping and by 6000 rpm I was flat-on-my-face with 200whp, the fun in that tune is short lived.

Currently on the new tune I am hitting 345whp at 5100 Rpm and 310whp at 7k rpm! This is a big deal and here's why. Previously I was making 345/500. It was 345whp at 3100rpm and 200whp at 6500 rpm with torque steadily holding but no extra power being made, something was amiss. Now with 100 ft lbs less torque, I am making the same power and holding power across to redline. A 345/400 car that holds to redline is a much more powerful car then a car at 200whp / 6500 rpm for obvious reasons.

When another 535 is shifting around 5500 rpm with an available 200whp, I'm still making over 310whp to 7k rpm and then I shift. Now thats a high reving BMW and on par with e90 M3 performance.

Peak boost is 19 psi and holds 13psi to redline. That the secret sauce."

Do you understand my question more clearly now that I presented you with an example of powerband curve?

I have seen other n63tu dynos as well and the consensus seems to be around 390rwhp, which if you do the math (15% drive train loss on a rwd vehicle) puts it at 458 crack. This is right in line with typical BMW under claiming actual HP.

The dyno BPC is showing at the net +127 claim seems a bit odd. I am not sure what vehicle they were running but it only did 350rwhp stock, far less than the 550i in the other example. Still using a dynojet, this would be only 409 crank under the same math assumptions. That crank number looks like the old n63 number to me and far less than factory. Even Terry @ BMS dynoed a stock 550i and it was 392.

So it makes you wonder whose claims are right. To be fair, DusH did all wheel dyno his 50i and it made 455 or something on a hot day and it was a mustang dyno which said typically reads 20hp lower than a dynojet. That would put it right into the 470awhp area. Again, this is in line with the other plots and even BPCs high number.

To me, that stock number BPC has is suspect. I think the REAL net wheel hp is somewhere around 70-75 with a stage 1 tune. This is far from aggressive for a BMW engine IMO. A stage 1 tune on my old 335i netted around the same on a dyno and that engine and platform handled it fine for years.

Hope that helps.

I would tend to agree with your statement as I would think it to be more like a 100 hp at the crank increase which would be a 70-75 at the wheels gain. Did Dush have a stock dyno baseline and then dyno with BPC flash? That’s all that would matter to see the gains he got, regardless of what type of dyno. Also keep this in mine the 550 if rwd will always put down a little more then a awd x5, more wheels turning more drivetrain loss, I even heard that auto trans all loses little more than a manual trans too. I have had my evo on both mustang and dyno jet dyno and it’s more like a 40-50 hp difference at 400 whp , my car put down 400 whp on dyno jet but only 350 on mustang. I’m going to dyno my car soon to see stock numbers before I put a piggy or flash tune on. I will post my results hoping to dyno it this Saturday and if not the next after.
