Have you accessed the ecu before? Or do you know if possibly it could be locked by a tuner?

That can be the case...Im not sure it came in with a blown engine so I rebuild it and put it back to stock.

If indeed it is done with Ecutec or Cobb do you think if i bring it to Subaru dealer thy will be able to put the stock map on there or will I have to get a new ECU?

I Can attempt to put a stock map on it myself BUT it might lock the ECU due to Immobilisers on 07 STI's.

Is there anything that can be done IF it is Tuned with ECUTEC???

I know a way if it is with Cobb which i will tray today.

Subaru will charge you $90 to try to unlock it. To remove the ecutek lock on my ecu, I was able to marry and unmarry a cobb ap to my ecu. That removed the lock, I've since then gone open source

I fixed it by marring and unmarring a Cobb AP to it. so now it is on a stock map.

But I have a few codes I need to turn off with Open source

1. The evap system code ( I have the heads holes pluged ) and pumps just sucking on Fresh air...

Then some how I got the Rear 02 sensor showing P0037 REAR O2 SENSOR LOW INPUT???It happened right after i downloaded stock map on it..Go Figure

Can I turn OFF this code and dont worry about rear 02 sensor or I have to replace it?

My main question is_____When I download stock map from the ecu With Open Source to erase the codes. DO I HAVE TO PUT THE MAP BACK ON THE ECU TO RESTART THE CAR WHILE IM MODIFYING THE MAP (FOR ANY REASON) ON THE COMPUTER???


OR IT DOESN'T MATTER I CAN HAVE THE MAP DOWNLOADED AND STILL RESTART THE CAR?

Thank You

You need to pull the Rom "map" and erase the codes. Then you flash it back to the computer.

Is that what your asking?

When you "Pull" the rom, you're just pulling down a copy to your computer. (the rom is still on the ecu also)

You said you're on the stock map now, but you have a FMIC, Downpipe, and intake.

You *could* drive it like that after you grab your rom and while you're working on the map but you should really drive easy I would say. Stay out of boost as much as possible. You also need to tune it for those mods and not just erase the codes and reflash.
