Default ECU Replacement or Repair

Hey guys! I donít really know where to put this but Iím gonna put it here since Iím a newbie lol
I have a 2006 STI and Iím pretty sure I have a faulty ECU cause I have a code (P0230) that no matter what I replaced still came up. I was wondering if you guys knew of any good ECU replacements or repair places?

2006 STi has immobilizer and has to be programmed to the car and the correct VIN written to the ECM. Dealer only and dealer Programed.

I donít mean to come off as an *******, Iím just being curious, but how is it possible that AEM has an ECU replacement? Is that what the extra wires you need to buy for it come from?

Just explaining the situation, Iíve delt with plenty of nuked/flashed/broken ECMís

First, Itís not an ECM replacement. Youíre either talking about piggy back tuning solution or a stand alone engine management system. Like AEM Infinity. Neither of witch are simply a plug and play solution with out significant knowledge of how to program and operate the system.

Second, All something like The AEM is capable of is strictly engine management, It is not a body control module, things like DCCD VDC, all of the interior operations sill have to function through the factory ECM/BCM

Also quoted from AEM ďTHIS PRODUCT MAY BE USED SOLELY ON VEHICLES USED IN SANCTIONED COMPETITION WHICH MAY NEVER BE USED UPON A PUBLIC ROAD OR HIGHWAY, Ē

The issue youíre having with the fuel pump circuit is either the harness, the fuel pump control module , or the pump and how itís wired. Possible the ECM has an issue , but throwing an aftermarket tuning setup isnít going to fix the root cause.

Thanks for the knowledge bro! Iíll go back in and check the wiring cause Iíve replaced all those parts. Hopefully it is a wiring issue
