Catalyst Protection on PRA Ecu

Post by contectr »

Hondata,
I have a Euro Civic Type R (EP3) with K20A2 engine and turbo kit GT3582R TScroll and sometimes i drive it on a Monza Italian Speed Circuit in the track day session.
The car run fine but i see after a few lap in the long straight (gear 5-6) the Afr ratio on my Plx Wideband go to rich at 11.0 ( Car tuned at 12.0 Afr)..
It's possible the ecu calculates a hot cat and use the catalyst protection table for save it???
How they work this table for boosted engine, collumns 10 is the collumns for boost table?
The value in the table are not the Afr target i think but a value that the ecu use for correct the final injection time and cold the cat..
If i low the value in the table i low the ecu correction ??

Thanks a lot

You need to look at the 'WOT Comp (cat protect)' tables. If you have no cat, make them the same as the 'WOT Comp' tables.

If the tables are identical then is is not the cat protect enrichment which is changing the air fuel.
