"How To Tune Up The ECU on 1991 Mazda Protege"

1991 Mazda Protege Front View

I have an 1991 Mazda Protege and I want to know how can I get into the ecu and tune it? like make injectors pump more fuel into the cylinders and for it to suck more air in to just try and improve power a little bit.

Answer: The computer (ECU) is the LAST thing you want to ‘tune’. At best, you can replace the rom with a hotter chip, programmed by someone who spent years specializing a particular brand and engine size. Stick to add-ons like headers, cat back systems, turbos, nitrous, etc.
