recently dropped usdm sr20. the car originally came with a jwt ecu programmed for bluebird injectors and 9.5 compression. dont know what maf is programmed to the ecu. i lost the maf that originally came with the car. i picked up a gti-r maf. now i fire up the car w/o the maf revs up to 2k with no misfires. i connect the maf it misfires in idle and all through rpm.
now my question is. could it be a bad maf? or the ecu not programmed for that maf could cause the ill misfire?
any thoughts would be helpful.
