The reason for the reflash is to download an upgrade. Replace ECM with factory new or used. Replace the old with the new sensor and do the reverse of the procedure to keep the sensor fitted. Thats absolutely absurd that you have to code a fuel injector after replacement. When installing your unit the first thing to remember is to disconnect the battery prior to removing the old unit. If the car starts without problems, then reprogramming is probably not necessary. Most of the time, after replacing the sensor, if you don’t relearn the sensor, the ECU might store the old sensor data, which causes throw the code. Wipe the terminals down and allow them to. You can pull the MAF from the intake pipe and air filter by removing the clamps. You should expect to pay between $150 and $300 at a local repair shop or service center just to have the ECU inspected and tested. If your Toyota ECU is failing, you can try to reset it. After the time passes, reconnect the battery cable to the terminal. One way is to use a multimeter to test the voltage. If you have a faulty ECU in your car, then you have to check the Ignition coil to replace or fix it. Undeterred, Kilmeade kicked things off on Monday with the briefest of references to the man he was temporarily replacing. 1) use the ecu matching the engine 2) purchase a third party tuning ecu and get it programmed to suit 3) have a tuning company re-program the existing ecu from the old engine - this may or may not be possible - they will tell you.
