Will I be running rich if I install bigger injectors?

W a good o2 sensor doesn't the computer adjust the (guess) duty cycle? I mostly wanna run bigger injectors (17.5) because of the "better atomization" and they are newer. I'm running a jc chip. Stock everything else

You will be fine running those injectors. I like to run them in stock or semi-stick M20 engines. Nice upgrade over the old stockers.

yes

So to be clear. 17.5 injectors on a stock motor will have the same a/f as 14.5s. Thanks.

Yes, the DME will adjust DC for the slightly larger injectors. Your MPG gauge will no longer be accurate, but you shouldn't notice any major effect on your overall/actual MPG. The difference in size is roughly 30cc which isn't much. I have been wanting to do this upgrade myself, but have been lazy and am looking for someone who has a set that is reliable (clean and known working), clean and has new o-rings or they are selling a refurbished/rebuilt set.

will the OBC mileage readout still be accurate?

[nando]

no

[shiboujin]

no

[nando]

how will your OBC mileage be correct?

it won't. your duty cycle will change, and the OBC is based off the stock injector size. it works the same way the MPG gauge does.
