Short ram problems
Asked by Mycar1516 Dec 12, 2017 at 05:02 PM about the 2015 Nissan Sentra SV
Question type: Car Customization
I have a 2015 nissan sentra 1.8 and it will not run
with a short ram intake. Just curious what I need
to do to change that? It runs fine with stock but
refuses to idle or run with the short ram.

When you got the short ram, did it require a bigger MAF sensor? Some of the aftermarket manufacturers require a larger MAF due to the increased airflow from the new intake. Smaller engines are particularly susceptible to this. You may want to check. Also, make sure you hooked the air hose back up correctly to the intake. You need air, spark, and fuel to make combustion. Somewhere, you've got an issue with the "air" side of that equation.
I built it no leaks or connection problems, I spent the time building it right, I think the oem maf sensor is rejecting the short ram. I just don't know where to go from here, if an aftermarket maf will fix the problem?
Air is my problem just dont wanna drop 170 on a sensor to find out it doesn't fix the problem.

Being that you made it yourself, it makes determining which aftermarket MAF would work with it. Do you have any idea what kind of air flow rate your intake is working with? I admire ingenuity when I see it, but bear in mind manufacturers of intakes dyno test their units for hundreds, if not thousands, of hours and this is exactly why. Getting a piece like that dialed in is a lot of trial and error.The other potential issue I see is the aftermarket MAF is going to be processing an EXACT amount of air through it at an EXACT rate. Even if you were able to get it to turn over and idle, you'd likely have a check engine light on because it probably won't be flowing the exact right rate to make it work. All I can suggest is to try a few different options and trial and error it, but you may be better served to purchase an aftermarket kit and save the trouble. If money is the issue, I certainly understand but being that your car is a 2015 I doubt you want to drive it around with dash lights on already. I do wish you the best with it though.
Thank you for being honest and yes money has been rough but I do understand what you mean. In that thought process it may be better buying a regular. When I put it together I knew the maf wasn't reading correctly, from what I have researched it is sensitive. So from what I understand an aftermarket sensor won't read oem specs, but still may not read without problems...that would have been my next question. Once again I do appreciate the help.

You are welcome. I hate, and I mean I HATE, being the bearer of bad news. I'm sure you've made a quality piece and the tubing isn't the issue. Money is rough for everyone right now so I can definitely appreciate you giving it an attempt. I would be concerned that you would spend money on a sensor and it not fix your issue. If you're going to throw a couple hundred at an issue, I'd just buy a regular kit when you can afford it. You may have to save for a bit, but when you buy it the install will go MUCH easier.
