Ms42 ews

Hello guys,

My second post and being soo specific, sorry.
I´ve been looking at a damos for MS42 and wondering if EWS delete is such a pain as some seem to believe or not.
I´m used at turning off switches with Bosch ECUs but Siemens seem to be a bit different.

Here´s what I believe have to be tweaked but could use some help from more experienced guys:

K_DTC_IMMOB_PE
K_DTC_IMMOB_N
K_DTC_IMMOB
EPZ_INC_EWS
EPZ_INC_EWS_N
EPZ_MAX_EWS_PE
EPZ_INC_EWS_PE
EPZ_MAX_EWS_N
EPZ_INC_EWS
TIMEOUT_EWS
T_IMMOB_N_WINDOW

And in doubt with "SPERR" maps does it refer to "wegfahrsperre" like bosch does?

Anyone messed around with times and values, will it be ok to try with zeroed values and "maximum" times? :)

Thanks in advance and hope I can help too.

Cheers,
Diego.

The MS42/MS43 never came out on a car designed for boost. Boost maps don't exist for MS42 and MS43.

The DME uses MAF, so it does not "see" the air pressure in the intake manifold.
