what do the map notes say?

Designed for cars with stock intake!!!

If you really want it then do it and log the car a couple of times and make sure everything is ok.

Technically, you can, but it would not be in your best interest. If you want to put on the intake, do it and get protuned.

Bad advice. Logging won't do crap. DO NOT run the intake at all whatsoever.

The OTS map is also compatible with Cobbs short ram intake. Get a protune to maximize the potential of your APS CAI.

You need to STOP posting when you have no idea or proof. You can can ONLY run the intakes listed on in the sticky thread in the AccessPORT forum. How do I know this? I asked Cobb directly. Proof>>>>internet opinions.

The reason cobb will tell you that the ONLY intakes you can run on their OTS maps is that they are INCREDIBLY careful and anal retentive about their claims. I am not saying this is a BAD thing, its just the way it is.
They will not release a product or make a claim without a ton of testing (I mean a LOT, seriously, loads of testing) to ensure that it will work well.

As there are many aftermarket intakes other than theirs, taking the time to test all those intakes, is just not a realistic proposition. Therefor, its easier for them to just say only stock, or their intake.

The reality is that there are a couple intakes out there that DO WORK FINE. And yes, there is proof. A lot of people having pulled datalogs, showing no problems, IS proof.
Cobb telling you no, doesnt change the reality that other intakes DO WORK FINE.

Saying datalogging does nothing is laughable at best. I am not even sure where someone can come up with that mindset. Datalogging tells you beyond a shadow of doubt how your car is running. In other words, if you slap an intake on your car, regardless of it being the Cobb intake, or something you cobbled together from old soup cans, you can datalog the car and know 100% if the car is running safely.



I really think that telling people NO, without explaining why or why not, does a huge disservice to them. If you understand what makes an intake work well or not work well, and what intakes out there fit certain specs, you can tell right off if something is most likely going to work. Then you can look at overall results from years of using a part, and come to a very solid conclusion.

Here is the reality
Stock intake
Cobb short ram+heat sheild
SPT short ram+ heat sheild
K&N Typhoon short ram+heat sheild
APS65mm cai

ALL OF THOSE have been shown to work well with either no engine management, or with the AP off the shelf maps. The AP, just like the OEM ecu, can adapt to minor changes just fine, and none of these intakes cause anything other than VERY minor changes. We are talking .1-.2 difference in AFR right off, which the ECU adjusts and compensates for withing @100 miles.

Now this is very good information it should be added to the Accessport sticky.

BTW, dont get me wrong, I am not saying slap it on and never bother making sure. While you can be fairly safe (as safe as any non tuned motor can ever be, and any OTS map, is untuned) doing so, you really should be logging the car after you add any mods, just to make sure. Its not hard to see what the IAM is, and if its way down, you know there is a problem.

Honestly, you should do that even if you use the exact mod list that Cobb (or any tuning company) recommends. You can never EVER just slap a mod on your car and know 100% that it will run safe. I have seen cars that slap engine management on (of any variety, not just the AP) and run so poorly that they will likely have engine damage in short order, and I have seen them run amazingly well. Even an OTS map, with the exact recommended supporting parts can be very unsafe. Or very safe.


What baffles me is that people jump up and down about running a non cobb intake, but they completely ignore the fact that Cobbs OTS maps are also designed for a high flow cat downpipe. People scream and yell about an intake, but they completely ignore that many people are running catless downpipes.

I had to remove my APS 65mm intake after I switched from UTEC to the AP. The short term fuel trims were maxed out at idle, because under the cobb map, the car couldn't get to the target 14.7 afr.

If your really wanting to use the intake, id reccommend putting on the intake and getting a protune.

How long did you give it?

I ask because 9 out of 10 cars are fine with it.

But, this is an EXCELLENT example of why you have to datalog ANY changes. Regardless of what others experience.




Really, and this SHOULD be obvious, if you have an AP and want an intake and dont already have one, just buy the Cobb intake. Its not that much more expensive than the other aftermarket intakes, in fact its cheap than some.

If you have an intake, install it and datalog it. WHen you first start the car, if the AFR isnt where it should be, let it idle a while (20 min maybe) then drive it NICELY around the block or something for 15-20 min, then see where the AFRs are. They should be much closer, if not dead on.
If they arent, maybe give it a little longer. If it doesnt come in line then, take it off till you get tuned.


But in general, those intakes listed, work fine. This guy is an example of one that doesnt. Datalogging is the key

Car was still warm from my drive to the shop, we set the UTEC to bypass, loaded the COBB stg 2 map, and watched the short term fuel trim and idle hunt for about 10 minutes until we pulled the plug. Switched over to a factory intake within a matter of minutes, and BAM . . . no more idle hunt or fuel trim.

YMMV.

Running 92 oct (on the 91 oct map) @ sea level @ approx. 65 degree temp.
