Default Cobb Accessport Stage 1 Log - DAM 16

Hey Guys,

I just got the AP in my 04 WRX wagon. 62k miles. Only other mods, K&N air filter and a Grimspeed Up-pipe. I set up Stage One with the AP 5 days ago.. I've driven the car everyday till the oil temp hit at least +70c... Today, I did my first data log... Just learning how to read it - would you guys mine taking a look and let me know if anything looks odd?

I followed the loggin directions on the cobb vid - logged in 3rd floored from 2500k - 7k - although I see from the data I started loggin closer to 3k and stopped just under red line..

I'm a little concerned the the DAM is locked at 16... Here's the log from today:
https://docs.google.com/spreadsheet/...GVrYzFtVnhrUlE

I also did a log yesterday, however I didn't remember the instructions correctly and ran through all the gears... but - DAM is locked at 16 there too.. link:

Oh - I just got an oil changed yesterday - if that matters.

thanks in advance for the look.

Drats.

I saw this from cobb:
"Dynamic Advance Multiplier (DAM) is a measurement of how happy the ECU is..."
SO based on these comments - I take it that 16 is "happy" and 1 would be "unhappy?"

Hello. The DAM maxes at 16, so that is what you want to see (after it has learned up from its intial value of 12 after a map reflash or AccessPORT install).

It looks like you are running the older v300 maps. We made a number of improvements to the maps in the v310 version. I would go ahead and download the v310 version of your map (from map repo - see link below), use the AccessPORT Manager software to transfer it to your AccessPORT, and reflash it to the car (make sure you reflash it and not use the realtime function in this case). The v310 is the best version to run for your car.
http://www.cobbtuning.com/info/?ID=3061

Looking at your logs, your A/F Learning 1 hits some extreme values (+10%). This usually indicates a fueling issue. In the case of these older cars, it could be a "tired" Mass Airflow (MAF) sensor. This causes airflow to be underreported which can cause you to run lean. I would go ahead and replace the MAF sensor with a new one. It is so critical to engine operation that if there is any doubt, you always want to replace it. Other issues that could cause erratic fuel trims are a bad/aging front o2 sensor or intake/boost leaks.

Thanks Bill - I see in the notes form the map "MUST USE FACTORY OR COBB SF INTAKE SYSTEM..." Could the K&N filter have an effect on the MAF sensor? I'm up in the mountains for the week - do you think a MAF sensor clear could help?

thanks

Do you have a K&N panel filter or K&N intake?

Just the panel filter... and as mentioned - I have a cat-less up-pipe.

Download the new Maps - and re-flashed. Starting the heat cycles tonight. Will repost logs later in the week... Thanks for the help!

In theory a K&N panel filter could impact the MAF sensor, but even if it did, it would likely to be minor (especially compared to an aftermarket intake). I don't think that is the case here. Any other mods (like catless uppipe) will not impact fueling accuracy. The same is the case for driving at high altitude. I would go ahead and replace your MAF sensor. It is a very common problem on these cars and even if that isn't ultimately the main problem, it is a good practice to replace these when they get old due to how critical they are to the safe operation of the engine. The front o2 sensor is another one that has problems as they get old and at higher mileage.

Thanks Bill,

I was poking around online and had a hard time finding one - is this something I could 'upgrade' - or - should I just go to the Subaru Dealership and buy one?

thanks

I would just stick with the stock sensor, but you don't have to necessarily buy it at a dealership. Check with your local auto parts store.

Re-Flashed with the updated stage 1 maps.. did 3+ warming cycles... ran a log tonight Check it -
https://docs.google.com/spreadsheet/...UN0bVpVd2t1Ync

AF learning starts high, but then tapers off pretty quickly - that seems good. Everything else look good?

Already ordered the new sensor all the same, can't find any tutorials on installing - seems pretty strait forward.. anything special I should know beyond how to use a screwdriver?

Thanks!

Nope - it is straightforward - just install it the same way that the current one is installed. After you install it, reset the ECU via the function in the troubleshooting menu of the AccessPORT. This will reset your fuel trims to zero so they will learn properly for the new change. Drive for about a week on the new sensor without reflashing a map or resetting the ECU and then see what your fuel trims look like. Another culprit with these old cars is the front o2 sensor which tends to degrade with age.

Ok - the O2 Sensor died and was replaced about 7000 miles ago - so - that shouldn't be the problem. I'll post the chart again in a week or so.

Thanks Bill
