Mercedes 320 CDI EDC16cp31 boost limiters and diagnostic

Postby juice » Fri Feb 14, 2020 1:19 pm

Hi folks, i made a remap on my ML 320 cdi edc16cp31, increase boost maps and limiters by pressure atm, to around 2650 mbar
I attached my stock file.
I tried to log while driving, the fuel iq 90mm3 as i requested, all good with fueling, but for boost i can measure a flat line 2550 mbar, and looks like a diagnostic limiter or something
Boost maps are 1E514A, 1E538E, 1E5EE2.
Any ideas ?

Hi,

There is a good chance its your diagnostic limit.
Have you got a map pack so I can have a look at your file?

Thanks,
