- 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!
