Auto and manual BINs different by only one bit B_autget. For manual this bit set to 0 and for auto to 1. Also there can be some small calibration changes but it does't matter at the most.
But to find this bit you need to disassemble your BIN or compare your BIN with manual one in which software version is the same. Also this thread contains OLS file for old P80 platform. If you'll read this thread then you easily found it.

The manual files do have kickdown etc values. Post your file

I can send you 50WRHJ software for manual and auto transmissions. And you can try to find a difference in kickdown etc values.
Or 50GPHJ software for auto and manual.

Again.

Just because you think you observed a thing doesn't make it valid for everyone.

10ERHJ (late 06 quality update) for instance or any other P80 project has around 4000..5000 Bytes difference between same engine and same emission standard but different transmission.

50WRHJ Tag has been used for all software projects from some MY05 and all MY06 on, four different layouts exist.
Differences are torque converter stall speed maps, reverse engine / transmission speed plausibility maps, Pedal maps, torque monitoring maps, idle torque reserve maps, fault paths along with replacement values, ...

50GPHJ has less differences, but around 1000 Bytes also.

I wouldn't say those are non existing or not important.

I flashed XC70 B5254T2 AW55 with S60R TF80SC software. Injectors and turbo were swapped to 440 and K24. Car runs fine and makes 0-100 in 6.5 secs. Please expain your arguments. All these words about kilobytes of differences just words. But I want to thank you for your criticism. It helps to continue investigations and dig deeper and deeper.

What does this statement have to do with different calibration of manuel and automatic transmission ecu files?

I think you might don't want or can not understand what the point was: because it works for you in a small window of the possible operating range an conditions, it must not do under other circumstances.

See, the B5254T2 has "high" compression, B5254T4 has "low" compression.
What will affect this the most beneath filling calculations?
I will tell you: knock control.

But, if no knock occurs, maybe because you drive 100 octane and in cold conditions, you will not notice any problems.

Now the other guy in Denver in the summer, facing 40 degrees Celsius and above 1000m altitude running 90 octane will blow his engine.


Different example: maybe your approach for whatever will produce problems when kickdown is engaged.
But your customer didn't use kickdown while testing your software?
You will come here, tell everything works. Next day customer uses kickdown because he needed to and gearbox beaks. Will you come here and tell? I guess not.



The reason im arguing with you: I don't want to explain all this every day four or five times in each message i receive. So come here, tell things you observe as this.
Not as fact you have clarified the last twenty years you worked with those Volvos as others here did (including me).

Good luck with all this

I'm running my B5254T2 engine with 1.4 bar of boost on 98 RON every day. Even on 30 deg celsium. And had no problem with detonation. About kickdown. I flashed s60 t5 with B5244T5 engine and AW55 gearbox. It was my tuned flash based on S60R TF80 software. And again car runs fine. It made 6 secs 0-100 on FWD. No kickdown or all these horrible problems. Also I switched S80 2.9T bin from AT to MT. Because where was no s80 with 2.9T engine with mechanical transmission. And again it works. Even cruise control. And I'll switch one XC90 with 2.9T engine to MT after I'll finish my GUI software for flash. Now owner has a problem with engine limiter on 4000 revs. All these practice. But I understood you and will dig deeper into difference between AT and MT calibrations.

I had downloaded them all and never saw a manual identifier in the file names back in August. When i went through it all again I realized one of them was a manual for 99, but it was not labeled in the file name Tongue. Ill go back and compare this to mine.

It's a manual file cause it constains this string: P80 TO B5254LT MAN 2WD EU

Thanks for the help!

I am working out a deal for a 1999 C70 2.3T ECU. Will use it as the primary one. Im curious though, people have been able to swap the immo chips and even flash them on this forum. If the ETM, ABS, and other modules are non coded (verified through a volvospeed post where someone swapped the DIM, VGLA, Locks, key ring, keys, and ECU), and i am able to reflash the eeprom. Then would the manual ECU itself simply plug into my new system. All the boot loading, program control, etc would be isolated to the ECU itself, and if the immo is reflashed to my setup then would it not act as if it is in its original car?

I would need to verify the ETM and ABS work, but i am unsure if my above understanding is incorrect. Ill probably just test this out in the summer or when it warms up outside.

I'm not fully understand you. But if you reflash EEPROM in your new ECM module to car's ECM module then immo will be OK. It works for 1mb software. And as far as I know it works for all ME7. You have to read this and other topics again and again.

prometey1982, did you find maps for soft launch control?
Quote
Soft Limiter
Very rudimentary "launch" control can be added via using two RPM limits[47][48]

VNMX (1157E) - The vehicle speed for activating the raised (normal) rev limit. Set this as low at it goes (1.25 km/h) so the launch control shuts off as soon as you start moving off the line.
DNMAXH (16304) - This is the RPM above rev limit when the fuel cut comes on. Tweaking this helps make more boost on the limiter. 50 RPM is a good start.
ITNMXH (16308) - Dwell time under lower limit before activating the upper limit. Set to 0.
NMAX (1630A) - Ends up being the launch RPM. 4500 is a good start.
NMAXOG (16312) - This is the raised RPM limit which becomes the standard limit. Set to your desired redline.
TMOTNMX (16316) - Coolant temp for activating raised (normal) rev limit. Set this at -48 so that you can rev past the low limit while car is warming up.
TNMXH (1631A) - This is the time duration of the raised (normal) rev limit. Set this to its maximum value of 655.3500 seconds. In theory, this may trigger at some point, but nobody has reported such a thing yet.

I found only NMAX

Quote from: P80R
Does anyone know how the BIN & IMMO are interconnected? i would like to flash my R ecu bin to my xc ecu. Can anyone explain or point me in the right direction so i can do my DD.



On P80 in bin is some definition of engine type, this has to match to you transponder box. If you change engine type in bin of ECM you have to change 1 byte in transponder box to the right engine type. There is 1 byte for engine typle like LP turbo, HP turbo, non turbo or diesel engine. Without the change of this byte your engine wont turn on if you try different bins of different  engine types...

For most conversions I'd still use the ecu that came in the car, or a clone of it. Compare the closest bins and look at where and what the changes are and do, if the file structure is slightly wrong because you're just swapping from "a" T5a to "a" T5m with slightly different a2l's you could be looking at non starts, comms errors to modules and wiring incompatibilities creating more problems. I haven't done that yet myself so feel free to add or correct anything.

The 4k rev limit is to stop you neutral dropping. I found it in some with a2l's; 20xxxx.a2l but not looked at yours yet, wouldn't that work as your soft launch parameter when switching to manual? ..thinking aloud...
