1990 2.3l quad 4 Dohc 16 valve 5 speed in a fiero
Is there anyone out there that can give me an idea of why the stock ve table is way rich. The mods I did were port matching exhaust to the stock 4-2-1 header, (exhaust ports were very necked down!!!) made them more aerodynamic too. Only cleaned up intake ports.
I understand and header will scavenge and it will be flowing a lot more air due to larger ports but having a little trouble under standing what these changes did to the engine characteristics. The ve table looks completely different! And wondering what other parameters are going to b way the heck off. Raising injector pw seems to do good but lowering accel enrich seems to do good too? Will opening exhaust lower need for accel and power enrichment.
Basicly asking how a pro with a lot of experience would start this tune and what they might expect the engine to do or how it changed?
Thank you for your help!!!
