Guys, look at this ignition map. Is the optimum angle at low loads? Stock compression ratio

There is a max pre ignition angle maximum
in the ECM. 37.5 pre ignition I think is the maximum.
At my V8 I raised the angle until knock detection worked. At low load the knock detection isn’t active but you feel if the engine has more powe or not. Test it during constant driving.

find a program called fairdell hexcmp2, you can view 2 bin files at the same time and see the differences plus copy data from one to the other really easy with that program.

Hi
attach complete txt log file and pic from max boost pressure map values.
You should explain what is your ecu (AAN, RS2, MAP sensor (2.5; 3.0, 4 bar, stock Bocsh or MPX6300,400)), what is your settings in Winlog (Logger configuration - map sensor type) and what is the main version of ecu soft, Prjmod SD or stock or ... to be to have more base info.

[QUOTE = d_anev; n2056088] Привет
приложить полный файл журнала TXT и рис из значений карты максимального давления наддува.
Вы должны объяснить, какой у вас блок управления (датчик AAN, RS2, MAP (2,5; 3,0, 4 бара, стандартный Bocsh или MPX6300,400)), каковы ваши настройки в Winlog (конфигурация Logger - тип датчика карты) и что является основным версия ecu soft, Prjmod SD или стоковая или ... чтобы иметь больше базовой информации. [/ QUOTE]
Карта mpxhz6400a, чип наддува с сайта m2.3.2, топливный чип сделан на основе файла Big Turbo с m2.3.2. Настройки и настройки winlog тоже от Дмитрия Прж. Лог-файл прикреплю позже.

You need to adjust air when ignition change isn't enough... ignition is faster than air stepper but sometimes not enough
83DF is setting the target rpm when AC is activated. (10 is the factor)
This is done in 4565, it's also removed.
code:00004565 code_4565: ; CODE XREF: code_44F1_IdleControl+6F↑j
code:00004565 lcall code_FF9_tableAccess ; 9BA0 / 9BAA

code:00004569 jb RAM_20.4, code_4578 ; Jump if Bit is set
code:0000456C jnb RAM_20.6, code_4578 ; Jump if Bit is clear
code:0000456F mov A, #2 ; Move (Op1 <- Op2)
code:00004571 movc A, @A+DPTR ; 83DF NSAC - min engine speed for AC
code:00004572 cjne A, RAM_5, code_4575 ; Compare Operands and JNE
code:00004575 code_4575: ; CODE XREF: code_44F1_IdleControl+81↑j
code:00004575 jc code_4578 ; Jump if Carry is set
code:00004577 mov R5, A ; Move (Op1 <- Op2)
/edit:
Is also removed in fuelcutoff routine.
1C6E mov C, RAM_20.6
But this only affects the rpm change for fuel cut during AC on

Originally posted by jonn48 View PostHello guys. Again it is time to use the air conditioner and again the problem of increasing idle speed is relevant. I tried to do everything as written above, copied hex to the specified addresses and inserted it into my file, I made a scalar in the xdf file to the address 83df, but this did not help. Raising does not work. On the original rs2 file, the enhancement also does not occur. I do not have enough knowledge in disassembling, so I ask for help with this problem. How to make the increase in speed like the stock and tuning AAN files?"The really good drivers got the bugs on the side windows." Walter Röhrl

for a simple cheat just raise the setpoint RPM from 800 to around 950RPM. thats what i did on my car for now and that was enough to compensate for the AC being on. never looked into the code Acki posted but i will now because i have had this issue on several other cars with the AC mapping not having an affect on the cars.
