8882 Bre кто-то юзает его? Опции

А то все хром, убердата, турбоедит. А тем временем БРЕ очень солидный продук только вот разобраться бы полностью в данной проге..
Кстати только у него заметил скриптец для настройки ИТБ на моторе...

Я его пользую. Какие конкретно есть вопросы?

Не понял... Т.е. он сам решает сколько надо лить в зависимости от соотношения смеси? т.е. самонастраиваемый? Если так-то моя идея накрылась медным тазом...

Даталогин в нем действительно реализован. Именно поэтому я сделал вывод что на мозгах pr3 и pw0 его можно получить, т.к. BRE, наскоько я знаю, заточен именно под эти мозги.
Что ты имеешь ввиду под автоматической правкой топливных карт? Есть опция пересчета значений топливных карт при изменении объема двигателя или производительности форсунок. Ты об этом?

Не я про это

Using the Real-Time AutoTune
BRE supports real-time AutoTune. To use this you must have the datalogger open, a properly setup wideband o2 sensor run into your ECU (2nd o2 sensor (pin C8) on an obd0 VTEC ECU), and an ostrich emulator emulating in live edit mode. BRE needs to know the afr in order to do this. Using the real-time AutoTune feature is very easy. All you need to do is hit Ctrl+Shift+R (or click the Logger->Start Real-Time AutoTune menu item) with the logger running.

Before you start it for the first time, though, there are some settings in the Auto Tune options dialog you should at least look at. These options are available in the Edit->AutoTune Options... menu on the ROM window (not the datalogger). Also, you need to adjust the target AFR in the main ROM window to your desired target AFR.

First, the basics: each time a cell is hit in the logger, the current, east, south, and southwest cells get assigned a weight based on the interpolation values. So a weight of .20 would be 20% usage of that cell on that sample, a 1 is a 100% weight on that cell, meaning that cell is only being used and the surrounding cells are not being used at all.

The Options:
Min Change:: The minimum change that the tuner will make. If the percentage difference between the measured and the target mixture is lower than this value, nothing will be edited.
Max Change:: The maximum change that the tuner will make. If the percentage difference between the measured and the target mixture is higher than this value, than this value will be applied.
Min Freq.:: this is the minimum sum of those weights for the tuner to make a decision in some particular cell. i.e. 4 samples with a .5 weight in, say, cell 2,5 will allow the tuner to average those samples and make a decision on how much to increase or decrease. The higher the number the better the average but the slower it is.
Min Cell Weight: the minimum weight that will get averaged into the "good samples" pile for that cell. i.e. no sample in some cell with less than 20% usage will be considered in the decision making process. The higher the more "accurate" the sample will be for that cell. BUT I have found that sometimes there is more of an even distribution. For example, my car it idles with an even distribution of ~.20 to ~.25 on the 4 cells in the idle area and so the tuner will do no adjusting because all the cells are outside the acceptable range.
Max Col Deviation: the maximum that some cell's pulse width value can deviate from it's east and west neighbors. In this case the cell being edited by the tuner cannot be 15% larger or smaller than the east or west cell. This helps keep the tuner from raising the crap out of a cell then lowering the crap out of another cell nearby which would result in an ok average sometimes but would make it unpredictable.
MaxRowDeviation: same as above but for the row neighbors.
LatencyIntervals: this is the minimum number of samples that must occur before the tuner can make another decision. Without this, the tuner does not account for the time it takes for the changed value to go through the ostrich, the ecu, into the engine, through the exhaust, to the wideband, through the controller, back through the ecu and into the logger. If this is low (like 0) then the tuner tends to over shoot because it does not see the change right away, and when it does, the afr is way past target. This option is the reason real-time autotune is slow. The problem is that it kind of needs to be slow to allow changes to propagate. I have tested this value at 3 with a 50ms datalogger interval and it was very accurate.
Cell Block-out: There are 2 (or more) tabs in the AutoTune Options dialog that are labeled "* Fuel Block out." Each of these tabs corresponds to one of the fuel maps and allows you to specify which cells to NOT auto tune. When the background color of a cell in one of these tabs is white, the cell WILL be auto tuned. When the background color is black, the cell will NOT be auto tuned. To change the state of any cell, first highlight the cell in question, then right click and choose the option you wish to use. Shortcuts are Ctrl+B to block a cell or range of cells, and Ctrl+U is to unblock a cell or range of cells.
Notes
The realtime autotune is not for driving fast. Its for tuning cruising, idle and/or gradual changes in rpm and/or map. It cant cope with big transitions because the ecu adds corrections beyond the maps at those times, then the tuner sees the change in afr and tries to adjust the map (which isnt necessarily causing the afr change). I use it to tune 800 - 5000 rpm cruising under different loads. I typically find a nice route with hills and flat portions, turn on the real-time auto tune, then go for a short leisurely drive. I try to stay away from big pulls and big changes in TPS.

Each time a correction is made and you are logging to a file, the correction from the Tuner is placed in a column called "Tuner Adj." in the log file. Its in the format "(column`row) multiplier; (column`row) multiplier;"

An example would be: (1`2) 1.05; (1`3) -1.023;

Using statistical AutoTune
The statistical autotune is used by pressing the button at the bottom left of the Analyzer form. It is assumed that the ROM you want to autotune is open and the latest log from that ROM is opened in the log analyzer. When the button is pushed, the differences in the % Differences tabs are applied to the fuel maps with respect to a couple options available in the AutoTune Options dialog:

Min Change: The minimum change that the tuner will make. If the percentage difference between the measured and the target mixture is lower than this value, nothing will be edited.
Max Change: The maximum change that the tuner will make. If the percentage difference between the measured and the target mixture is higher than this value, than this value will be applied.
Cell Blockout: There are 2 (or more) tabs in the AutoTune Options dialog that are labeled "* Fuel Blockout." Each of these tabs corresponds to one of the fuel maps and allows you to specify which cells to NOT auto tune. When the background color of a cell in one of these tabs is white, the cell WILL be auto tuned. When the background color is black, the cell will NOT be auto tuned. To change the state of any cell, first highlight the cell in question, then right click and choose the option you wish to use. Shortcuts are Ctrl+B to block a cell or range of cells, and Ctrl+U is to unblock a cell or range of cells.

Что такое БРЕ?

2TJ
извиняюсь за флуд, но что хуендай тибурон делает в аватаре???

БРЕ = убердата = турбоедит ~ chiptuner(ТАЗ)

Скажем так..БРЕ такой же по функциям как Убердата,но менее раскрученый изза обд0 направлености...Турбоедит рядом не стоит с бре...ЧИПТЮНЕР для тазов тем более :)
Кста радует что чел пишуший бре не закинул проект а постояно чтото клепает и постояно отписывает и фиксит баги..
Щас от иду прошью новую фичу шиф лайт...мелочь а приятно :)

Потому что Аккорд отдадут через две недели. Сфоткаю - будет новая аватара. А на тибурон не наезжай, ему каждую гонку почти все машинки того же класса сливают. Привезён из японии, установлен 3.0 V6 двигатель, коробка yamaha на заказ, чёрный кит Jun Racing B.L. Black.

оффтоп имхо

off: хуиндаи огрызаются однако...)))
