For some reason, on the original rs2 chip, there is also no increase in speed and a no switch to the "idle isv linearization AC on." I see it in trace mode with emulator in tuner pro. Could the removal of R660 somehow influence this?

the removal of R660 should not affect it. bosch tends to ground unused ADC inputs from the factory instead of letting them float as open pins. just fixed the AC in my S6 finally and now that i read this thread its really bothering me that the AC control part of the code isnt working right lol.

i have an idea of using the old automatic in gear target idle RPM table as a table for target idle RPM when AC is on. i didnt test this yet but i think it will work, this is what i changed below.

ROM:455E ROM_455E:                               ; CODE XREF: ROM_44F1:ROM_4557↑j
ROM:455E                 ljmp    ROM_7FA0        ; Long Jump

This is the table switching depending if AC is on or not.

ROM:7FA0
ROM:7FA0 ROM_7FA0:                               ; CODE XREF: ROM_44F1:ROM_455E↑j
ROM:7FA0                 jnb     RAM_20.6, ROM_7FA8 ; Jump if Bit is clear
ROM:7FA3                 mov     R2, #2          ; Move (Op1 <- Op2)
ROM:7FA5                 ljmp    ROM_4565        ; Long Jump
ROM:7FA8 ; ---------------------------------------------------------------------------
ROM:7FA8
ROM:7FA8 ROM_7FA8:                               ; CODE XREF: ROM_44F1:ROM_7FA0↑j
ROM:7FA8                 mov     R2, #3          ; Move (Op1 <- Op2)
ROM:7FAA                 ljmp    ROM_4565        ; Long Jump

This takes out it reading the constant RPM value for AC on.

code:00004569 80 0D                    sjmp    code_4578       ; Short jump

so this gives you a 4x1 table based on coolant temperature at 0x9BA6 to adjust your target idle when your AC is on. works in my head and when i run it through IDA disassembler so it should work when running in the ECU.

Let me know if this method works on the car. Unfortunately, I do not know how to work with the disassembler, so I can only watch. Still, it's interesting why the rs2 code doesn't work as it should.

it works fine. post up your motor chip and i will patch it for you with this.

I will be very grateful!
If it doesn't bother you, check the LC code to see if its operation is normal.

Большое спасибо! Утром я внес поправку в xdf, вечером постараюсь написать в ecu.

I will change the code to "add some rpm" to the map value.

[jonn48]

I want to express my deep gratitude to vwnut8392, the corrected code works well! There was a problem on my car: when the AC is turned on, the speed does not increase to the values indicated on the map, but when the climate turns on for heating, the speed increases. On another car, everything works as it should. I think the problem is in the climate control unit.

Guys, how to connect innovate lc-2 with Winlog? Did someone do this via the usb port using the lc-2 digital output?

I connected my Zeitronix using a software port splitter.

What is the safe option for decap patch?
patched or patch removed?

Thanks

Guys, have you noticed a difference in engine operation parameters on the same firmware but different ECUs? I set up and drove the ecu 551B, now installed the same firmware on the ECU 551AA and saw a richer mixture.

Hello, Can anyone share PRJ mod BIN files for setup like RS2 + or k26hybrid or something similar I need something between Stock BIN and BIG turbo to compare in order to learn how to corectly tune my car. My setup is K24 7400 turbo.

Hey. There are files for K24 7400 and Bosch nozzles 550cc, tfsi coils. Not completely configured, but it works adequately, it will take a few adjustments to the ignition and boost for your fuel and car.
