Having some trouble turning off DTC's on a 2011 WRX. I uncheck the boxes i want, but the codes still set like i didn't do anything. Anyone else having this issue? Or is it a problem with this ECM?
Thanks,
Derek

A lot of DTCs don't actually turn off with Subaru ECUs.. I have an open support ticket for this. It's a real pain on the dyno when you pull the rear O2 to install an AFR sensor for tuning and start popping codes..
Here is what i got from support, looks like you have to take a class in order to do this:
Thank you for contacting HPT Support.
WE our software is emmission compliant and some dtc's you have no access to anymore, If you take the 2 emmissions tests this will allow you access to some of the dtc's but not all.
https://tunertools.hptuners.com/
All you need to do is use your account info and login to tuner tools then go down to classes and take the 2 tests, apply the code in editor and you'll gain access.
No dice, did the class and everything, updated my software and firmware. I reread the car and verified that the codes were unchecked, but they continue to run regardless. Working with support- i will update this as i work through this
I am being told that we can no longer mess with DTC's for any reason by support- bear in mind that this is a competition/race car that never sees public roads:
"Well you've heard of the EPA.

My guess is that they are no longer supporting the engine diag tab in the software. So if you get it to work great, if not you are on your own and probably out some credits
