Post subject:  Carberry idle issue for my 2002 WRX

Hello, I have recently flashed the Carberry rom tp my 2002 WRX. The only information I had going into this was that the Carberry rom had some added on features and enhancements that the stock ECU rom did not have. Right away I noticed a difference in performance. Wow, I thought to myself, just imagine what it could do if I actually got it set up properly. One thing that got my attention, was when I first start the car, its a little rough at idle nut eventually it calms down. I did some logs and looked at the learning view. And honestly, looking at the data I could see some anomalies, but have no clue what is causing it I could really use some help with understanding what I am looking at. And I would even be able to offer some donations but it would have to be in bi-weekly installments, living in southern California having 3 kids and job that just doesn't come close to be able to afford life let alone spend on modifying a car that my wife absolutely hates)

I have rambled on too much about nonsense, now let me tell you what Im working with:

EJ205
(K&N Short Ram Air Intake
TGV Deletes
TD04
Stock light blue injectors
Stock WRX TMIC
Stock Front O2 sensor
Stock BOV
Stock Boost Controller
Install AEM IAT Sensor onto the TMIC to the left of the Throttle body
IWIRE Hybrid Speed Density cable, connecting the MAF and the IAT
Catless downpipe
3" exhaust cat had been hollowed out.

Any advice would be greatly apprecated, thank you

Also I have no idea which parameters I should be logging, so Im sure that would be a great starting point. Thanks again

Notice that your A/F learning is pegged at 15% in the first two ranges? You have injector flow scaling set to 575cc (roughly what pinks flow), stock light blues flow 420cc. Fix that immediately.

That map also had a ton of other errors.

Start with this map: Youll have to go in and change everything over to SD.
