AFAIK the GIAC flash is encrypted, which is why it cannot be read out by the COBB AP.

How does the ECU read it if its encrypted?

The stock DME is encrypted

Get a JB4 and run it on top of GIAC with 1-2 psi overboost when meth is active.

Too bad it doesn't work. It would have been nice to have something new to tinker with

I thought GIAC offered a flash loader? Couldn't you order that and swap a "stock" map to the DME And then overwrite the stock map with the cobb? Or would that not even be readable by the AP? I thought the dinan tune was encrypted also and thats why the cobb just overwrites it with a "stock" map.

You can tinker with the jb4 on top, great gauges and easy to setup. Only boost is added, timing, fueling etc is still managed by the flash. I am running stage 1 with 5 psi on top .

It does not. Just as with the Dinan flash, COBB uses a generic map to replace the tuning flash (which is then irretrievably lost).

The GIAC flash loader actually does not load any maps, as they're already stored in the DME. It just activates them.

It would be best to PM Rob@Cobb and ask him.

Anyone else notice that? Ive looked at my logs and even sent them in to cobb and they said they look normal.

So after looking at more of my logs I'm not making full boost, 16-17 psi until 4k rpms. From 2k rpms to 4k rpms my waste gate dc is in the 75% range and then drops to 45% when I make full boost. My load requested is also higher than actual load until 4k rpms. If anyone wants I can email them my csv files to take a look.

When looking at cobbs dyno database there cars on stage 2+ sport are hitting 16-17 psi by 2800 rpms so I know something isn't right. Im gunna contact cobb on monday but was hoping you guys may have some insight for me.

Started my car this morning, it was 20 fahrenheit. Drove the car for less an mile, and it went in limp mode. Didn't rev more then 2500 rpm.. any ideas Cobb?

Read the codes........
Than you can search them on the forum to get an answer on what they relate to

sdstatestud88 · 12-10-2011, 06:43 PM

Any insight on a Release date Enrita?

How does it compare to the stage 1 + JB4 setup you were using?

Laid Black 335i · 12-10-2011, 09:11 PM

Question for anyone who can answer:

I just had 3" Catless Downpipe's installed and the "Service Engine Soon" / SES Light Came on as expected. From my research, the only way to get the light turned off is to upgrade to a Stage 2 map since it's already calibrated in the stage 2 map. Can I upgrade to stage 2 with just Catless DP's and BMS DCI? Or do I need an upgraded FMIC too? It is winter time here in Maryland so it's pretty cold outside. I am currently running the Cobb Stage 1 aggressive (93 oct) map.

The other option I saw was getting the downpipe fix from BMS.

Any help appreciated.

bigdnno98 · 12-10-2011, 09:13 PM

you can run the regular stage 2 map and it will supress the SES. you only need the FMIC to run the Stage 2+ map.

Thanks for the quick response, when you say "supress the SES", you mean it will turn the light off correct? I will eventually get an aftermarket FMIC when funds allow it, but my only focus right now is getting the light turned off.

bigdnno98 · 12-10-2011, 09:35 PM

Yup, light will go off unless you go back to a Stage 1 map. It usually takes around 50 miles to come back on once the tune is removed or Stage 1 map is flashed.

^Cool. Also just saw this post as well:

sems faster but it depends the boost you put on top but the engine is happier with higher ignition advance, very responsive. The ST mapping is very nice indeed especially for an AT.
