RomRaider

Change in RR the data type switch to see the raw data. It will look like numbers around 128.

I think this PDF will be useful for understanding M3.1

Added stock BINs from different M50

I will be glad of any information on data registration on these ECUs. I have an ADS adapter, maybe it will work with the TESTO logger, I have not tried it yet

thanks bro your bins seems to be working they are same as we have , and i think fabio has used this pdf motronic 3.1 to create this definition , and changing to raw data and numbers will look 128 that doesnt solve the problem TunerPro software os already show that way

Hi again! Fabio I tried the last settins you posted even with more ignition like - 20. It is not like poping its something like a little burbe. Maybe we should add something more.

Do you think we can make it more aggressive and if have a way to make it pop also without touching the gas pedal

You should make Log and analyze it how Actual Ignition looks because no one here knows how to make those Pops and Bangs in M50, maybe the Ignition/Fuel Map isnt Base Map or something. Read more about it in Guide or search net.


Make Log with Editions and Without see what changed.

How to make log on m3.1? I can watch live data m1.3-m3.3.1 using Launch X431, it records, but during movement there are very few frames per second and very frequent disconnections.
Are there other methods, or is this only possible with an emulator like moates or cobra rt? May be Testo logger+ads interface?

people are using ostrisch for that
someone can show us how to make definition file like the one FABIO make it for 402 ecu ?
let complete all the other ecu 400( rare one), 403, 405 and 413

Hello! I found a video on youtube
launch control on Bosch Motronic 405 https://www.youtube.com/watch?v=YSh0KqM5pZI
and flame popcorn on Bosch Motronic 403 https://www.youtube.com/watch?v=q-YCGuMDtjM

How can this be done without ostrisch/cobrartp ?

Hello everyone, I have been researching info about motronic 3.1 and how to make pops and bangs. Fabio's settings work well when the gas pedal is accelerated a little. There are a few temperature maps related to rpm that are responsible for cutting injection (maps 4x1, 5x1, 6x1...). I have searched with wols for all the possible maps and I have done some tests recording chips (I don't have an emulator). Map 19 keeps the injection working and the car popped without touching the pedal but the rpm dropped very slowly and the car did not go back to idle... It stayed above 1k rpm (hot car). I share a photo with all the maps that I have found to see if someone can find the correct map (tried on 19, 20 and 17 and nothing has happened except what was mentioned with 19). thank you very much to all.

can u try table 31 ?

No, I can’t understand this map and doesn't look like a rev map…
If I activate the last cell of the map 23 at 6500rpm I get that there is always gasoline injection but I think it works badly because the car does not stop injecting gasoline, several pops are heard but they are weaker than when the accelerator is pressed a little.

The other maps that seem to be of revolutions and temperature do not do anything or work badly... I would like to know if there is any guide or help to identify each one of the maps and know exactly the function of each map. In another forum a colleague with an m42 engine found a 6x1 map that was the cause of the injection cut, but I don't have any map with values similar to his. If someone knows something and is so kind to contribute information I would appreciate it. thank you very much and sorry for my english

Tables 19 and 20. Fuel restore rpm with and without AC.
I'm yet to find the ign retard table on decel though. This is why you have rev hang.

Oh, it's make sense!
If this table depends on coolant temperature, it may be one of the tables that I have in the image above. Some values are untranslated because I don't know all the formulas, that's why strange values appear in raw data...

can we make an update for the xml with the new tables ?
if anyone wanna try something i can try it on my car
im searchinf for flashable eeprom for thoose ecu
actualy i found it and i have it but its too big and need little bit of hardware work
its an 27SF010 or 020 it have same adresses like the 27C but its flashable you can use it many time
i use it to try multimap ( one flashable eeprom not 27c eeproms)
i have the schema if someone is interested i can share it here

Ok, I have a solution that works. Definitely the map that cuts the fuel injection is the temperature map 23. In addition, the idle ignition table must be modified, both the values of the Y axis and the data. Basically, the ignition is retarded at a certain rpm, thus achieving pops and bangs without touching the accelerator. For the modification of the ignition map you have to use wols because in romraider the data is not displayed correctly... I leave here the definition file for romraider for people who want to investigate and try. The only flaw with this solution is that some gasoline is being injected until the car is close to idling, that's where it stops. It would be necessary to investigate if there is any map to control the injected gasoline with the accelerator stopped, but it may be that this control unit is very old and does not have it or it may also be one of the rpm maps that are still in the file.
