Hey! Anyone has base map for b20 405A 11,2:1 ( or around ) and fuel pump?

 

You need more compression for those cams. They are very hard to make idle below 1200rpm and are very choppy like a big block chevy. Hope this is for non daily use only and you have some great springs and valves in your head

 

Is good compression, the 405a are not more than a itr cam with 10 ° less duration. The LSA is much higher ( 113° and 104° itr ) and ABDC is lower too ( 44° and 45° itr ).

The only thing that could really affect is the intake lift that is equivalent to a stage 2 vtec (12.1mm). I can leave the idle at 1000 rpm and it keeps working problems smoothly. I was only interested in some reference map since I don't have the knock tool and I have the conservative map

 

You can get a chip basemap from here. http://www.phearable.net/ecu-chippin...p-basemap.html

You are better off getting the car tuned.
