Do you have supplies on-hand to repair a 2002 Infiniti G20 Sport A/T (49-state, non-California) ECU with part number MEC22-613 A1 1X24 and DTC P0505? The mechanic has already replaced the IACV+sensor and TPS. I'd like to place an order today, send the ECU out tomorrow morning, and receive the repaired unit by Tuesday, do you think that's possible?
If you need it, my VIN is JNKCP11A52T511239. The ECU also has the number 23710-6J118 on it, but this seems to be shared with other versions of the ECU which are not compatible.
The car is in limp mode and Idle Air Learning never completes. Sometimes there is DTC code P0325, but only once in a while.
Also, is there any reason I should upgrade the TCM firmware? Is the TCM separate from the ECM, or integrated?

The ECU you have is an all-in-one unit. There is no separate TCM. We can do a full rebuild which should fix the P0505 code. This is a common failure with this ECU. The P0325 code could be a secondary code however we'll see what's going on and clear those codes. You can purchase the repair service from the link below:
