Mass air sensor and chip

    So I need some help. I recently installed headers and exhaust on my 2014 scion tc. I have an aem intake arriving shortly. Is it worth buying a new mass air flow sensor and possibly chip and programmer to tune? I hear chips are waste of money because our computer will reset. So do i bother with air sensor?

    yup.. your research is the truth. There is no chip that would work with our ECU (Computer). And what would a new mass air flow sensor do that the oem/factory one isn't doing? it's measuring the air flow and telling the ECU how to match that air with what it's metering out via the fuel injectors. Just a waste of money to get any other MAF (mass air flow) sensor.

    The only issue you need to consider is the cold air intake. if the CAI air filter is an oiled filter that can foul out the MAF sensor. Which will require it to be cleaned. CRC brand sells an awesome MAF sensor cleaner. The MAF already gets dirty due to crankcase vapors being re-introduced into the intake stream for emissions. And that's with the regular air filter/intake system. So just plan on cleaning the MAF more often, usually 6 months is what I clean it (stock system).

    I think you've done most of your upgrades already.. The ONLY way to make more power is forced induction like a turbo, but at that point you're rebuilding the engine to put up with more pressure. Toyota had a supercharger for the 05-06 I think it was.. they dropped it, it was destroying the engine! whoops!
    Thank you for the help. I had the k and n box filter. But got the aem cold air intake. Which assuming id clean as often as I and n. And yes turbo is too much money. I wouldn't mind lightening the car. But the carbon hoods etc.. Are dam expensive. Any other ideas please feel free to suggest. Just for fun I've been sanding and polishing block and other parts in engine compartment to look real clean. Taking forever though

    hey if it's worth doing it's worth taking the time! Nothing ever got to perfection overnight! but yeah carbon hoods are insanely expensive. I remember they said that carbon fiber could be mass produced and that would reduce the price.. um.. that's not happened at all! lol..

    I remember someone saying what I'm about to say.. And they're right. That the tC is already at a sports car deficit from the beginning because it has a glass roof. All that weight at the highest point on the car! So it's a sporty-car not a sports car. I agree you do as much as you can, but there are limits. I think you've done great with the mods so far. Those are about the best you can do without something like a custom turbo system. $15k+ and for those that did spend that money they weren't that much faster! Now that has to suck!

    I think what is awesome about the tC is what it is. What it has to offer. When I look around at all the other vehicles out there none match what the tC offers. Even this many years later. crazy.. just glad to have one!
