Hi just bought a power fc code Ecr 010 000
its got no controller. so i unplugged batery plugged in power fc .its kicking but not starting. air con works fans heater stereo ect so i was under the impression everything goes through ecu so if they work does that mean ecu works and just needs to be tuned . ive got 555 injectors z32 map waiting to go in and high flowed turbo with dumppipe.At the moment its got 3 inch exhaust , pod filter , boost controller, stealth intercooler, does it need to be remapped, thats why its not starting cause might have a previous owners maps. any advice would be appreciated thankyou.
