Hi guys, Got an email today that my A9L ECU is on it's way back from ECU Exchange in Green Acres, FL. Their price is just under $100 to go completely through the ECU plus shipping with 48 hour turnaround. They found a burnt internal ground, that with your help, I had already found. They also discovered that the power supply was faulty. So, they repaired the ground circuit, replaced the power supply, replaced all the capacitors with upgraded capacitors, replaced voltage regulators and beefed-up areas where Ford ECU's are known to fail. They also provide a lifetime warranty and will repair at no charge, even if the failure is due to my own incompetence. I never would have gotten to this point without all of your help. Thanks so much and I'll let you know what happens after the reinstall. Any suggestions on anything I should do before I reinstall the ECU to make sure that I don't blow it again? As you know, you already walked me through the rejumpering of the O2 harness.
