Default Please help! stage 1 problem

I just got my ap yesterday, flashed the stage1+SF 93 octane map and logged it today in 3rd gear S#. During my run, the car hesitated around 4k rpm's and shortly after I hit redline, all these lights came on: check engine, traction control, cruise, and I could not get out of regular sport mode.
According to my ap, there was a solenoid a malfunction. I cleared the ecu with the ap to get rid of all these lights. Did I really screw something up? Could someone please look at my logs?

Sounds like you hit the overboost fuel cut (P0244 DTC). What year STi is this?

Did I cause any damage to the engine or turbo hitting that high of boost? Also, how does the rest of the log look?

The log shows that you are overboosting and boost is wavering (high, low, high, low, etc.). Temporary overboost isn't going to damage the engine, but you don't want to be doing that long-term. The first thing to do would be to download and reflash the low wastegate (LWG) version of the map and go from there (do another log).

You can download the LWG version of your map from our map repo:

Use the AP Manager software to get the map from your computer to the AccessPORT. Then reflash that map to the car.

Thank you for the reply. I reflashed with the LWG version but haven't had any time to log again. I really can't feel much power difference over stock which is slightly disappointing.

When you reflash a map or install the AP, it resets the engine control unit's (ECU's) learned parameters. This can make the tune feel a little soft until you get some driving in there. Give it a about a week and it should feel better. Get a new log when you get a chance and we can see how the LWG map is doing. Also get another log after about a week of driving and we can see if there are any fueling issues that may be making the car feel sluggish as a result.

They look good. I had the same problem minus the lights coming on. It takes a good day or two of driving around for the ECU to learn the new maps. Im not a pro with reading the data but from what I see it looks good. If you have issues again maybe try running the Stage 1 91 octane map. That won't hurt if your running 93 octane. Im sure one of the guys from Cobb will chime in on this post and give you better details then me.
