Latest v4 maps and firmware

Postby vishnut_vadmin » Sat Aug 07, 2010 4:49 pm

What's New:
Firmware #29 (please use with attached User Software v4.20)
1) Current Map Selection display: http://www.youtube.com/watch?v=h_PccbaV ... _embedded#!
2) Airbag Code Clear function added to Command Center: http://www.youtube.com/watch?v=ZJEZvdYx ... r_embedded
3) New Boost Response User Adjustable: http://www.e90post.com/forums/showthread.php?t=435393

Firmware #28
1) Added display calibration options for non-USDM cars that have 280kph speedos (instead of 260kph speedos)
2) The default two-stage Shift Light RPM value has been reduced from 8000 from 7500rpm.

Firmware #27
1) Vishnu Command Center is now fully enabled. For more info, go here: http://www.e90post.com/forums/showthread.php?t=427976
Note: 135i users will notice that the cruise control stalk does not have a "2 click" movement when push or pulled. So in order to enabled/disable the Command Center, you can also push/pull the stalk and hold for 1 second. The Procede will interpret this as a "2 click" push/pull input.
2) 2 Stage Adjustable Shift-light. See here for more info: http://www.e90post.com/forums/showthread.php?t=427851
3) Cruise Control Stalk Mapswitching and Map 3 enabled. See here for more info: http://www.e90post.com/forums/showthread.php?t=427866

Firmware #25
1) Revised warm-up boost control routines for smoother shifting when the engine is cold (oil temp>160F)
2) Wastegate Compensation AutoTuning now active
3) SES light flashes for map indication have been removed and replaced by tachometer needle confirmation
4) DSC button mapswitching for Z4s should be functional
5) Revised Autotuning target scaling

Firmware #21
1) Fixes the issue where start-up map selection (map 0 or map1) was dependent upon selected gauge display mode (fuel level or boost). No other changes.

Firmware #20
1) Now capable of displaying boost pressure in the fuel level guage. To toggle between display modes (either boost or standard fuel level), simply double-click the hazard button while the engine is running and in performance mode (not valet mode). The boost display mode option is not functional in valet mode. The display mode is persistent upon engine turn off/on.
2) In a 335i, the display range is 0-20psi. So that means that 1/2 tank represents 10psi. 3/4 tank equals 15psi, etc,. In a 135i, the scaling is different due to differences in fuel gauge geometry. Looks like 1/2 tank is more like 15psi. This will be resolved soon.

Firmware #18
1) CAN Knock and CAN Coolant temp now display ACTUAL AFR for bank 1 and bank 2 respectively. These changes are reflected in the 2 new datalog set-up files that you will need to drop into your "Procede" folder.

Firmware #17
1) Now the map defaults to Map1 (instead of Valet) right after the initial firmware update. No other changes.

Firmware #16
1) Ignition Correction AND Boost AutoTuning is now active in BOTH standard injection and progressive injection modes.

Firmware #15
1) Fixed display bug where debug byte 5 would nominally exceed maximum boost value.

Firmware #14
1) Revised conditionals for AutoTuning. Will prevent the false learning that occurred during light load conditions.
2) Ability to enable/disable AutoTuning functionality in both map1 and map2.
3) Ability to adjust base wastegate position during idle and light load conditions in order to minimize wastegate rattle.
4) Gear compensation for AutoTuning.
5 New logging channels: CAN DME Lambda bank1 and CAN DME Lambda bank2 (from front wideband o2 sensors)
6) Revised warm-up compensations for boost limiting.

8-17 Maps
1) Both maps (especially 6AT maps) have far less boost taper at high RPM
2) Maps now available for upgraded turbos (ASR, Turbo Dynamics, EPL, RB)
3) Default Boost control DC Gain is now 50%
DETAILS:
-Currently Boost Autotuning is only active in both standard injection mode or progressive methanol mode. This means that Injection Mode must be equal to 0 (standard injection) or 1-99 (progressive methanol). If set to progression methanol mode, autotuning is only active when methanol flow is above the meth flow threshold. If methanol is disabled or runs dry, autotuning will stop and the car will run on the Map1 settings. For more info on how progressive methanol autotuning works, see here: http://www.e90post.com/forums/showthread.php?t=403236

-Autotuning is also only active when oil temp is between 170 and 270F. So don't expect it to work when your car is cold. You can see the status of the AutoTuning system by monitoring Debug Byte 3. 0= not active. 1= active.

-Boost Autotuning is has the authority to adjust boost pressure by +/-5psi. This means a total adjustment range of 10psi. The lowest boost setting is 10psi. The highest is your start boost plus 5psi or the Overboost value, whatever comes first.

-The Maximum Boost value in the user adjustable menu now defines the upper AutoTune limit for boost pressure. Boost will not rise above that value regardless of how low aggression target is.

-Ignition correction Autotuning has full authority to move Ignition Correction anywhere from 0 to 100%, depending on conditions. To help things out, it's always a good idea to set your initial ignition correction, right in the middle, at 50%.

-As before, both Boost and Ignition Correction autotune values reset to default/initial values when you conduct a DTC mapswitch. If no DTC mapswich is conducted, the autotuned values are persistent upon ignition power off/on.

-There are a few new debug channels added to the datalog setup files (see attached). So make sure you put them in your "Procede" folder like usual. You'll see one of the new channels in the user software window (debugbyte 5). This represents the current autotuned User Boost level just like debugbyte 2 represents current autotuned Ignition correction.

-When driving, it is normal to see debugbyte 2 and debugbyte 5 change independently of each other at times. At other times, you will see them change at the same time. The AutoTuning logic is still in it's early stages so expect enhancements/changes over the next few months. But as is, it still works very well. And, if anything, it errs on the conservative side which is a nice place to start.

-To adjust base wastegate position, you will adjust the Wastegate Position user adjustable. The default value is 90%. If your car has wastegate rattle during idle, light cruise and decceleration conditions, try reducing this value. Reducing this value, will move the wastegates more open during these conditions. At the mimimum value of 30%, wastegates will be fully open. PLEASE NOTE that this feature only works during very light load conditions. If your wastegates rattle at moderate to full load, there is nothing we can do as moving wastegate position will have a negative effect on boost control. As such, this fix only works during off-boost, light load conditions. At the very least, you will be able to reduce the severity of the rattle. At best, you may be able to eliminate it completely. Try to keep this value as high as possible in order to maximize initial tip-in boost response.

GETTING STARTED:
As before, Map1 is set to run initial/starting settings of 13.5psi and 50% ignition correction. Map is set at 14.5psi and 50% ignition correction. Stock or mildly modified cars can start off on map1. More modified cars can start off on map2. Although after a bit of autotuning, both maps will become the same, so this isn't even important. But it's always more desirable to start off conservatively and let the Procede's autotuning logic make things more aggressive-- instead of the other way around. Of course, you can always change these initial/start values as you see fit. Just keep in mind that Boost Autotune has a limited adustment range (+/- 5psi). So if you expect Map2 to be an autotuning 20psi 110oct race gas dragstrip map, you'll have to have a start boost/UT setting of at least 15psi.

IMPORTANT:
You must reset learning (by DCT mapswitching) after making User Torque or Ignitionn Correction changes to the User Adjustable menu. If you don't, the Procede will have to relearn around the changes you just made which, if big, will take some time and possible make the tune temporarily too aggressive.

HOW TO TEST:
The nice thing about AutoTuning, is there is not much for you to do. In this case, just pick either Map1 or Map2 and drive. And let the Procede do the rest. If you want to speed up the learning process, doing a few 3rd gear full throttle pulls (4000rpm to redline) will help since Autotuning is only active at WOT and full boost.

Frequently Asked Questions (FAQ)
What are these two datalog files (Channel_Data and Datalog_Setup) in the folder along with the maps and firmware?
They are for datalogging/monitoring. Simply put both files in your "Procede" folder. Windows will ask you if you want to replace existing files that have the same name. Select "ok". This files will automatically set-up your datalog preferences to record useful data. This is only useful if you want to datalog. But it's easy enough to do. So do it! :)

What map (1 or 2) do I run?
We recommend map1 since it is more conservative. Autotuning will adjust it upwards if/when conditions allow.

What is this new "Wastegate Compensation Autotuning" feature?
With this feature, the Procede will learn and adapt for your car's unique wastegate stiffness. This varies greatly from car to car. And compensating for it will make the car far more responsive and enjoyable. This particular aspect of Autotuning does NOT reset to 0 after a mapswitch or even after a firmware update. It is persistent. This learning process, however, is reasonably slow. And it learns the quickest at full throttle, between 3000rpm and 55000rpm. So to speed along the learning process, focus on these operating conditions. DO NOT ADJUST the "Boost Control Gain" user adjustable. Leave it at the default value of 50%.

My in-dash boost, afr, map # display readings are all off (ie, read too high or too low). What's going on?
Your Procede is in the wrong display/calibration mode. If the are reading too low, you probably have a 135i and are stuck in 335i display mode. If they are reading too high, you are probably a 335i and are stuck in 135i display mode. To toggle between display modes, simply hold down the DTC button (for 1 second) while double-clicking the Hazard button. This setting is persistent so you will never have to do this again.

What is the difference between the regular 8-17 maps and the 8-17 maps for Upgraded Turbos?
The regular 8-17 maps are intended for cars with factory turbos. The 8-17 Upgraded Turbo maps are for those running upgraded turbos (EPL, ASR, RB, etc,.) The main difference is in the Boost Control DC table. Please run the appropriate map. Running the standard maps in a car with upgraded turbos may cause overboost. And running the Upgraded Turbo maps in stock turbo'd car may result in sluggish boost response at high engine speeds.

My wastegates rattle upon deceleration and light cruise. What i can I do to shut them up?
Try adjusting the "Wastegate Position" user adjustable parameter. The default value is 90%. Try dropping this value in 10% increments until the wastegate rattle issue is resolved. Some cars may require values in the 40-50% range before rattling is solved.
