I've just reverted my 2013 FRS back to NA, from turbocharged running Ecutek. It still has the Ecutek cable/dongle paired, but I reverted to the original stock map.

When the car was running the turbo setup, I had wideband o2 assigned to the CPC input wire on the ecu, and I had the evap solenoid output repurposed to drive my 3 port boost controller.

I reverted the ecu wiring on the inputs back to stock, and I reinstalled the evap solenoid under the intake manifold.

I'm now getting two faults, P0453 and P0451 (with P0453 coming back first) when I clear the codes. It only takes a split second for the CEL to come back on after clearing.

Is there anything on the software side of things I could check? Was there anything I needed to revert to stock in Ecutek past what would load when re-writing the oem ZA1JA00C software?

I swapped back out the solenoid under the intake manifold with a spare, all hoses are hooked up correctly, and it still triggers a light immediately.

Thanks for any tips! The car runs great other than this with the original engine reinstalled.
