Title: What limit maps/constants need to be adjusted to allow higher boost via MBC/EBC? Post by: elRey on April 06, 2010, 10:37:41 PM What limit maps/constants need to be adjusted to allow higher boost via MBC/EBC?
I'm not talking about tuning a higher requested torque just yet. But allowing a higher boost via external control (MBC/EBC). I'd like to discuss in stages. 1st stage) boost higher than stock 'boost' limit, but below max 'torque' limit. 2nd stage) boost high enough to exceed max 'torque' limit. Assuming injectors/MAF/MAP are calibrated. Stage 2 might flow into the subject of tuning a higher requested torque which I'll like to avoid for this discuss. Or adjusting AFR/timing. Thanks, Rey Title: Re: What limit maps/constants need to be adjusted to allow higher boost via MBC/EBC? Post by: Tony@NefMoto on May 27, 2010, 04:22:26 PM You need to:
-increase the allowed boost deviation (deviation of actual boost from desired boost) -increase the allowed airflow (max airflow for the given RPM) I think that is it if I recall correctly.

Sorry for the late reply. Title: Re: What limit maps/constants need to be adjusted to allow higher boost via MBC/EBC? Post by: elRey on July 12, 2010, 12:17:23 PM Thank you again.
