Default ECU (Emissions) Help! EGR: Ready

Hello everyone,

I've got an ECU emissions issue and as far as I know I'm the first with this issue. I bought my 2011 wrx brand new and the first flash I put on it was the Cobb AP Stage 1, followed by the Perrin Stage 2 Map once I installed their downpipe. I then went to Cobb Stage 2, then to Torqued Performance Stage 2, then back to Cobb Stage 2 with SF Intake map. No open source tuning, only AP flashes.

I have to get emissions and safety tested this year so I put stock DP back on and unmarried the Cobb AP, which SHOULD have put my ECU back to stock settings. When I went to get tested, the report showed that my EGR monitor was: EGR FLOW: READY. Now, my car does not have EGR, so this is an obvious evidence of tampering to the county emissions department, and they blacklisted me so I have to return to their shop to get passed. They will not pass me until the EGR FLOW shows "NOT SUPPORTED." At the shop I go to here in SLC, I checked two tech's STi's ECU's - one with the AP, and one without, and both showed EGR NOT SUPPORTED. So, I am assuming one of three things: It was either Perrin's map or Torqued Performance's map that messed up my ECU, or possibly I need to drive a few more drive cycles before my ECU clears that out. Everyone I have asked seems to be stumped and have never seen this issue before. If I don't get this resolved, I will probably have to buy a brand new ECU from Subaru. Regardless, I will be driving a few hundred miles just in case that clears the ECU and fixes the issue.

Any help or suggestions would be greatly appreciated. I have also contacted Perrin as well as Eric @ TP but they haven't responded yet, and Cobb is no help.

Thanks so much

Sorry for your troubles. The AP v2 will return the ECU to the state it was in prior to the install when you uninstall it. The only way to uninstall the AP is via the "AccessPORT" -> "Uninstall" menu option.

If that was completed, then you should be on the original factory ROM, assuming you did not have a tune flashed to the ECU prior to installing the AP.

I think your best bet is to disconnect the car's battery for a few seconds. This will reset the ECU. This will cause the readiness monitors to be "not ready" until you do some driving. But, hopefully this will fix the issue with the EGR being reported as supported. I assume you have your own OBDII scanner to check the readiness monitors?

If that doesn't work, you can install the AP and then use the "expose ecu data" function to make a back up of the map that was installed to the ECU prior to the install (which you can retrieve via the AP manager software). If you post that up, I can take a look at it and see if there's something wrong with it.

The other thing to consider is that sometimes the emission station employees misinterpret stuff and get it wrong. So, that may just be the case here unless you were able to independently verify it yourself via an obdii scanner. For example, they could have been scanning another vehicle with EGR and mixed up the data with yours. Just something to consider. I would get/borrow an obdii scanner to confirm there actually is problem before trying to fix something that may not even be a problem.

Bill,

I have been in touch with Shayne as well. He suggested a hard ECU reset as well, which I performed this morning. I drove all day, and then verified at the shop with the scanner that the ECU still shows EGR FLOW: Ready.

I bought the car brand new from Subaru, and the only software I've used on there (with Cobb's and others maps) is the Cobb AP. The only other thing I can think of is that the ECU came stock with EGR showing ready, but that wouldn't make sense because the car doesn't have EGR to begin with.

Install the AP and then use the "Expose ECU Data" function under the "AccessPORT" menu. Also do the "Memory Snapshot" function under troubleshooting. Then use the AP Manager software to transfer those two files from the AP to your computer. When you have the two files on your computer, let me know.

Did any of this fix your issue. I'm interested in purchasing an ap but living in Ca with smog obd checks and such I'm hesitant when I read posts like this.

I have not received any data from the OP, but this is the first I've heard of his particular issue. The AP does not modify manipulate the readiness test logic, so the behavior will be the same as stock.

Curious BUMP. So I'm guessing no data was ever given? Perhaps somehow faulty stock ECU? Really curious if this has happened to anyone else... and i thought the AP could be used as an obd diagnostics tool, perhaps not in the same manner? Thanks for any answers.

On a stage 2 car if they are just doing your smog based off of your obd then u should be fine. My cars always pass because the code is defeated.
