No, not compatible.

 

oh alright, thanks anyways

 

cobb just brought out there stage 1 with the aem intake. i wonder if it will be alright to run a drop in filter and turbo inlet hose with that tune.

 

Just curious if it's safe to use the Cobb Stage 1 AP map on my EVO X MR with only a K&N Air Filter added..

I'm starting to get sick of cleaning my trunk every other week cause of the rich exhaust.

 

Hey guys, here is our current list of "off the shelf" maps: http://www.accessecu.com/accessport/.../EVOXMaps.html.

We will be releasing new maps for other popular intakes as well as the AEM including drop in filters and the AMS intake.

It looks like theres no gains from Stock Stage 1 map and AEM stage 1 map...so theres really no point of getting a intake or filter?

 

i think they made intake maps just for the AFR's IMO

 

I was glad to see that Cobb released a Stage 1 93 Octane tune for the AEM intake today. I've been running the Stage 1 93 Octane tune for a few weeks now and I absolutely love it. I'm really glad that Cobb decided to release the AccesTuner Race software for free, and I've been playing with the software, performing data logging, and SLIGHTLY adjusting tunes for the past several hours.

Flash back to a week or so ago, I read a post on how to make a DIY intake for the Evo X. Being as I bought a car as expensive as the Evo X, a few hundred bucks for an intake isn't really a lot of money, but I like little DIY projects, and a I figured a $30 cone intake would be a fun project - and if it sucked or didn't work with the Stage 1 tune, my Miata needs a new intake anyway. :-)

Physically any cone intake with a 3" inlet will fit on the stock MAF sensor housing. I didn't figure this would flow TOO much more than stock (so I figured it'd be somewhat safe with an already safe Stage 1 tune), since the stock MAF housing is used and obviously the diameter doesn't change... More on this later. The best part about the DIY cone intake is that it sounds AWESOME. You can hear turbo spool now and the BOV sounds almost aftermarket. It sounds awesome and I'm a ricer, what can I say.

Cobb specifically says that you're not supposed to use aftermarket intakes with the Stage 1 tune. I'd soon find out why.

With AccessTuner Race you can easily log pretty much anything the ECU monitors using the OBD -> USB adapter and cable that comes with the Cobb AP. After I saw that the Stage 1 + AEM tune was released today I decided to compare it with the standard Stage 1 tune. I found that the only thing that was modified was the Mass Airflow Calibration setting.

I decided then to do a few logs... I did second gear WOT rips with the following configurations several times and averaged out the results:

1.) Cobb Stage 1 93 Octane Map with totally stock car
2.) Cobb Stage 1 93 Octane Map with DIY cone filter on stock MAF housing
3.) Cobb Stage 1 + AEM intake 93 Octane Map with DIY cone filter on stock MAF housing

I'm the first one to admit that I'm not an experienced "tuner," but after researching definitions for the things I was logging, I quickly determined that Knock Retard was pretty important log data to take in to consideration. Obviously air-fuel ratio was another. Being as I don't have a wideband O2 sensor, I was only able to make value decisions based on what I was given by the logging that the AP provides. To get to the point, the goal was to get to a working tune with ZERO knock retard while still maintaining an AFR that was inside what a standard O2 sensor deemed "safe."

With the above in mind, here are the results of my "tests" given the above tests with their results, and my final result (in green) with a custom map based on the AEM map with the addition of some tweaking.



Keep in mind I tweaked in VERY small amounts until I received the desired effect. Temperature outside was between 75 and 80 degrees and we are approximately 800 feet above sea level.

I wasn't really a fan of all the red on the second (purple) column there. In my very limited experience, other logs threw some red flags as well with this setup when using the Stage 1 Cobb + stock car as a baseline.

I'm not sure if I'm 100% on track with this, but I figured I'd post my results and maybe get some input from people who are more experienced than I am. Here are things I've noticed - with the standard Stage 1 93 Oct map I did notice that acceleration was slightly weaker than with the stock airbox, even with the "*** dyno." This was before data logging - a week or so ago. I've actually had the intake removed from then until now for fear of doing damage to the car. Now, the car (with this tune and the DIY intake) seems as responsive as before (with Stage 1/93 and stock intake) and I still get the benefit of hearing what the turbo is doing.

Ignore this if I'm a total retard, I just thought I'd share.

 

Nope - they changed the calibration on the MAF sensor. The PEAK horsepower and torque may not have increased, but that doesn't mean that there were no power increases elsewhere. There's a lot more to power than just peak horsepower and torque. I played with this map today - see my thread here:

https://www.evolutionm.net/forums/ev...uner-race.html

 

I have read on here before that anything below 1 is usually ok on knock retard. I wonder why the stock map with OEM filter is hitting above 1 but the modified filter added doesnt, I figured the purple map would be way worse.

 

For what it's worth when I added my UICP to the Cobb stage 1 93 map my knock count went down.

 

Thought I might shoot this one out to you guys.

I just got my AP this afternoon and I cannot live without it now. I loaded the newest cobb stage 1 93 map for my otherwise stock X and tried out the dyno feature from 2,000rpm-6,000rpm in 3rd gear with a weight of 3600 lbs.

Result: 317hp @ about 5700rpm -----> that can't be right can it? I just saw a video of a stock stage 1 93 octane pulling in the 250-260hp range on a Dyno Dynamics setup. Did I input the wrong weight for it to be that off?

Is this because the AP dyno is still in the beta phase?

 

My comparison shows that the real dynos are much larger. After all the AP will fit into a shirt pocket while real dynos need almost a whole room.

 

LMAO


Nice.

 

Tried posting in Cobb Tuning forum, but thought I'd get more traffic here --

AP firmware version: 1.3.2.1-9588 (Beta)
Model: USDM Evo X MR
Map: Stage1+AEM 91 Octane (v1.0.1)

I'm noticing that from Live Data, my Relative Pressure Reading is showing negative values. My Absolute Pressure Reading has values between 5 - 21 PSI during normal drive. My Barometric Pressure looks right at 14.5 PSI.

Is anyone getting the same problem? Why does my Absolute Pressure Reading look more like the boost values I would have expected from Relative Pressure?
