Cobb AP w/ Cone Filter
Tried searching, couldn't find anything exactly what I was talking about.
A Cobb AP is on its way. I currently have just a cone filter installed. To go stage 1, I either have to upgrade to an intake that Cobb has a map for, or go back to the stock airbox, but the only intake I would want that Cobb has a map for is AMS, and it's pricey
.
However, I was looking at the Cobb SF intake, and realized it is essentially the simple cone-filter mod (right?), using the stock rubber inlet hose. Has anyone, or does anyone know, if you could safely run the Cobb AP Stage 1 + SF Intake map with just a cone filter? Or perhaps use it as a base map, and live-tune to safety?
Probably will be going back to the stock airbox until I get a compatible intake, but I was just curious if this made sense.

yes, there was a person that used the AEM intake map with a cone filter, then after some logging, tuned for zero knock using Access Tuner Race.

At first I thought it was just me, but the car didn't seem like it had as much pull as when the stock filter was on.
When they released the Access Tuner Race software I decided to do some datalogging both ways and see what I could find. The next day I saw that they released a COBB Stage 1 + AEM tune. I first did datalogging with the standard Cobb Stage 1 with and without the cone, and then tried logging with the Stage 1 + AEM with the cone, figuring it would be much better. It was. Gone was the mid-range power loss that I experienced with the Stage 1 + cone. Logging revealed that the ECU was still flagging a bit of timing pull and knock retard. Here's what I found:
The difference between the Stage 1 map and the Stage 1 + AEM map was just MAF calibration, so I decided to live tune with the cone, using the Stage 1 + AEM as a base. I was able to get rid of the knock retard completely and greatly improve the pulled timing to a little below the levels that I logged with the Cobb Stage 1 + cone filter.
Car runs WAY more mint now than when I was using the cone with the Stage 1, and according to logging is safer than using the cone with the Stage 1 + AEM tune.
If anyone has an AP and wants a Cobb Stage 1 93 Octane + Cone filter (rest of the car stock) tune for a USDM GSR, let me know and I can post it up.
