b20b ecu question

[crazyhondahead]

i have a jdm b20 motor with ls transs...i wanna use a 99 si ecu(p2t)..will the ecu make the swapp runn good??

The p2t from what I under stand is a b16 obd2 ecu. It will run the motor but not good. The b20 needs more fuel then a b16a at lower rpms its a torque motor. The other problem is the p2t will be trying to kick vtec. You don't have vtec or a vtec pressure switch. It will trow a vtec code. The best thing to do is get the ecu for your motor or get a chipped ecu and tune. List of ecus PGMFI.ORG - Grassroots ECU Development - Library . EcuDefinitionCodes
