mmmmm im not sure but i remember i learn this in an old post
i think the ecu adapting the fueling try to disable lambda and see what it change ( even if on these old engine lambda is not very very big deal ) but try this and see

hi forum im searching to disable lambda for my m50b25 non vanos engine 402 ecu , xdf in download section doesnt have maps or something
can someone help plz ?

but if cant detect knock and afr with it its useless !! better you change to ms41 bro its a loooooooooooooot better

im interested on boosting my m50b25 with same power 280-300 also if you can help me on that for the tune better to switch to ms41 ( m52 management ) if you wanna keep the oem management you have to find a way to detect knock and afr !! i suggest to tune it on dyno ... and buy a flashable eprom for t...

sorry bro but the F222 is selected by wrong !!! i dont mean anything by selecting it another think bro i wanna know , it about the rpm limiter in the 413 506 M3 ecu ( i believe its m3 us which is basicaly m50 stroker ) have this rpm limiters depend on speed i wanna make the same think so i can do a ...

this is the first step as i understand make the " table of table" in a list like this then i have the WOT fueling map start at 0x7234 = "8B 8A" , but i cant find it in this list ( i searched for 7234 , 8B8A, 3472, 34F2 ) or what should i found ?

yes yes i will relocate the new extended map in an empty space "FF FF ....." , then change to the new adress in the " table of tables" so it can wrok in the 403 ecu the table of tables in hex its 200 bytes and in 402 599 bin its 206 is that normal ? did i "select" the c...

i'm searching for it so i can use it after i extened some table
for exemple i wanna extend the WOT fueling table to 7000rpm and make new adress for it , and i MUST change the adress also in the " table of tables" so it can work , if you understand what i wanna do

if i undertand you well this should be "the table of tables" ???

you mean the table who have the adresses for other table start from 7A5E ? and finnish in 7B33 ???

Someone familiar with m50 402 motronic 3.1 ecu, can please help me to find the table who have the adresses for all the other tables i mean something like "the table of tables"
the ecu use this table to "know" the adresses of the other tables
thank you very much

you can use them if you wanna test
but the B25 and b20 software "tune" are different , so you better use the correct chip for your engine

im very interested bro

thanks

i did , check your email

hi forum i hope that you are ok i thought that it will be a nice idea and very usefull topic for most of the people if we share same update xdf's for thoose ecu's xdf in tunerpro site are good enought but i'm sure that some of you has added some new maps or something and here some of my xdf's i just...

xdf sent enjoy

send your email i will send it to you

how did you manage to it ??
which way did you did it ??

how can i find the "table of tables" in the 402 sw098 ecu ???

can you share your XDF ??

anyone know the decceleration maps on thoose ecu's ?? or 402 one ?
i already have the decelaration fuel map ( fuel overrun) for 402 i need the ignition one tobe able to retard it in deceleration

guys do you know or have any software to diag codes from thoose obd1 ecu's ? and if i need any interface ??

retard the igntion in low load and add fuel in the same area (part throtle body) ... and touch the pedal a little bit , it should pop

someone have better xdf than the one in tunerpro site ?

this one is working for both 405 and 403
you should know how this ecu work before tuning dont just change numbers specialy rev limit donc just make it 7000 or 7200 it will be wrong
