Programming ECU to remove EVAP codes

[Lumpyguy]

Is There a place or a way to Program or Tune out the Fuel/EVAP codes when you remove all the wiring and sensors/valves for the build?

RomRaider. Open source tuning for the Subaru ECU. Delete your EVAP codes permanently.

Just did that yesterday, it worked perfectly. I just used ECUFlash I downloaded from the site I bought the Tactrix cable from.

Cobb Access Port is another option, but it is a good bit more expensive.

If you go the Cobb Accessport route, you download access tuner race (ATR) from Cobb and use a laptop working through the Accessport device to delete the codes. I haven't done it yet, but just read up on all of it. The software is a free download once you have the pricey Accessport in your hands.

A google search will even point out which codes need turned off.

Thanks guys, Love this site!

Some of the codes involved: (pulled from another site, so some context is missing)

P0458 - EVAP system canister purge solenoid valve circuit low
P0447 - Evaporative Emission Control System Vent Control Circuit Open
P1400 - Fuel tank pressure control solenoid valve circuit low input

P0458 is a result of purge control solenoid missing (the two port solenoid in attached to intake manifold)

P0477 is a result of EVAP system missing??

P1400 is a result of pressure control solenoid missing (this is the part which had the broken nipple. If I leave this plugged in, even with the nipple missing, this code disappears)

Anyone with an Accessport know how to force pass readiness monitors? Or another method to 'get' there?

Thanks to everyone posting about the EVAP codes.

I'm going the COBB Accessport route, but the AcessTuner software now costs a bit more. Yes the software is free BUT you have to take an online course mentioned on the Cobb site and pass a few of the associated tests. The course is $149.

Took me half a day to go through all the online videos and pass the tests. Good information there BUT only the last 3 or 4 lessons deal with the COBB stuff.
