Another "Is Fuel Injection a Worthwhile Upgrade?" Question

Me thinks EFI would play nice on the post 87 magnum engines. Or at least have a roller cam etc. I dunno why I am thinking this...I also don't know why it wouldn't work, on an older engine, you'd need your intake air meter and a o2 sensor maybe something telling the computer where tdc is, is there anything else?

Efi will play nice on anything. It’s just more of adapting the technology to older engines, and using the technology on newer engines. You do not need to tell the computer where TDC is. It doesn’t care. You need an accurate crankshaft position sensor (with one of many patterns available) and a cam sync, (cam position sensor). The cam sync can be anywhere really. You dont necessarily need an “air flow meter” (mass airflow sensor) as most aftermarket efi systems use map, and you definitely need O2 sensors.
