hello all, I have a alfa gtv 2.0 ts 155 hp euro 2 (ecu bosch m1.5.5) with some minor modifications:
-direct suction dia);
-the final and the central section;
-throttle intake-polished and blended;
-the ecu remapped.
The car goes very well, but I have a strange curiosity?, regardless of my car,the question can? to be given to any petrol engine naturally aspirated, I think:
In case you would remove the catalyst,you know that the ecu should be remapped to search for, in part, to eliminate the vacuum at low revs caused by the absence of the catalyst, and to give a p? of gasoline in the most as pi? eliminate back pressure and the more you tend to lean(or am I wrong???). The question ? how we should touch on the maps in advance\injection to make the engine better with the new change??
I should point out that until now, all my cars I always try to map I, with your immense help and reading and reading on the forums. certainly not will be? a wonderful job(I believe that it is right to talking about a beginner in the field), but luckily I never caused any damage and I've always got something in the performance.....
Thanks a lot to all.
