RomRaider

Why not just the ROM you are working with and the helpful people here can suggest the required changes?

it is ms42 from e46 328i m52tub28 01100AD010000
i try to load rom but The extension bin is not allowed.

...

hello i started modifying my original file with only the maps available in romraider.

I think I have modified all the maps available for the intake camshaft but in view of the advice of sda2 maybe some map(s) is missing, I will continue to search

if someone has an opinion or a map (s) to help me?

hello some new today

what i learned here:

romraider allows to modify initial position, duration camshaft and table of vanos


comparing m54 b30 / b25 gives some idea of ​​maps to look for:

c_cor_cam_in_ref

definition:

calibration modifiable by application correction camshaft

value:

b30 -7.9 crk
b25 -1.9 crk
b28- 1.9 crk

what I know:

this map for MS42_01100AD
is not in the romraider definition as far as I know.

she allowed a "tipsb" (link in the conversation)
get a camshaft position reference value 6 degrees higher in inpa. (corresponds well to the modified value of b30)

and better operation of the engine (so obviously a real change in position) ...

c_fac_cam_sp_in_isapwm_min_

definition calibration factor inake camshaft setpoint pulse width modulation idle speed actuator minimum


value

b30 0.828
b25 0.398
b28 0.398

I do not understand anything more his name ...

if anyone understands the influence of this factor ?

Hi i tried to understand the c_fac_cam_sp_in_isapwm_min map so i started by trying to understand isa pwm this helped

https://motorsport-electronics.co.uk/on ... dIdle.html

but it is a factor there is no unit (millisecondes,Hz,% or degrees)
i guess the write order of the map has a meaning on who applies the factor to who?

to know if isa influence setpoint cam or setpoint cam influence isa.

I see the common point of the air between isa and intake cam would it be logical that the factor would be greater due to the change of cam?

for the "min" words is a minimum factor apply or a factor apply to a minimum value isa or sp cam?

I can not find any information on this map in German is fak_st_ms_vti

which could think that nobody modified it?

I have read many times to copy almost all values ​​different from b25 / b30 but "almost" remains to be defined for me.

I prefer to understand before modifying without knowing the final influence..

isapws Can be log?

hello

I watched all the thread of the peoples here having succeeded in the cam swap
I did not find more information I said to myself that maybe they had
explanation by mp ...
I have tried my luck without success for the moment (I do not lost hope).

inevitably I googled all the b30 / b25 differences not defined and I find nothing

I find this scalars in rr forum
(the 3 where I am 99% sure to have to use them)

c_cor_cam_in_ref
Maybe that could be useful simply for the reading good value (correction) in inpa?

c_cam_ini defined
c_cam_op_in. defined

The not defined

c _cam_sp_dif_max b30 0.75 crk b28- 1.125 crk

a maximum maximum difference between the reference and the measurement?

this does not deal specifically with intake cam but a specific calibration to ms42
does not take care of it?


c_crlc_cam_ad_ivvt b30 0? b28- 0.199?

this scalar is complicated
calibration correlation constant camshaft adaptive ivvt (vanos?) wow!
something related to vanos and cams..

this does not deal specifically with intake cam but a specific calibration to ms42
does not take care of it?

C_t_cam_sp_lgrd b30 40ms b28 50 ms

does not take care of it?

c_fac_cam_sp_in_isapwm_min b30 0,828? b28 0,398?

here we are talking about intake cam!
I think it is the last that it would be useful to understand.

I spent several days with three PCs (rr, TP, ols)
accompanied by all the definitions and damos of different versions for ms42 / 43

so to summarize I have all the Maps waiting futur logs
3 scalars which must be modified
4 mystery scalars (3 where I guess don't care about it and one that might have an influence on idle but nobody talks about it )

concerning the mechanical part I noticed that some people mounted the cam and ask the questions of the adaptations after.

And it does not speak about breakdown or defect
(it is the fear that I had).

I tell myself that maybe the cam is not recorded in the right place in the ecu but still works on it's original position scalar / map?

Thanks if anyone reads me again

Well, sorry for the delay.
I did All the comparing, editing and finally tuning with Romraider.
Dont know which missing tables is talked about but after all the car runs fine and according to the monitoring theres nothing wrong. No issues no malfunction no nothing but more power and fun.

I did a MS42 M52B28TU and modified it with MS43 M54B30 Parameters using Romraider.

Next up is a 3.46 diff swap

thank you so much!!
maybe we will have the answer one day of what is missing ... but if the car runs well like that I may not take the risk of modifying maps of which I do not have the definition.
How définition IS your ecu? I use a 3.48 dif also

I have latest ECU which should be C6 and for Romraider i use the latest definition files (dont have them on top of my head atm)

So whats your current state?

- mechanical Mods done?
- Software mods done?
- car runs?
- error Codes?

Thank you for your answer.
The current state is that the car has entered to have a replacement of all the silentbloc.
Which must be returned to stock for the technical control.

For the software part I have two ECUs a 011025 stock and a 01100ad tuned
As you have successfully adapted on c6
(without modifying another Map or scalar up to the unknown)

I am thinking of trying to switch 011025 to c6.
to be able to guarantee a result on this version.

for missing parameters (only available with TunerPro software) sda2 did not mention version (is this general in ms42 or just on the version it worked on?)

so I still have some mechanical work before the swap and I have to still learn how to log in order to control the state of the engine and its management before starting to modify

Hi!

What values did you set for injectors minimum injection time and dead times? Did you use the values from Wiki?
Thanks.
