My friend has a gsr block with a b16 head on it. He is currently using a b16 ecu for his engine. I was wondering if that is ok since his engine is 1.8 liters and his ecu is for 1.6 liters. Is there going to be enough fuel for it, or should he get a gsr ecu? Just wanted to see if it is dangerous for him to be doing that. Thanks.
