Default 318ti use Z3 DME for SAP delete and emissions delete

While looking at a few part numbers and knowing european n318ti's did not get a secondary air pump, fuel changeover valve, carbon canister valve, fuel tank pressure sensor.

I figured out that all European ti's use the same ECU as the USA Z3's.

with hardware number 1438877 vs our 1430105 <- these part numbers correspond to BMW numbers.

The pin outs are the same. With the exception of the wiring harness not needing pins 64,65,66,and 72 that control everything listed above.

There may be some early USA 1997 TI's without secondary air pumps and the rest of the parts running z3 ECU's.

Another benefit is the ability to flash multiple different software with winfkp 141439320 would correspond with the correct flash for a direct ECU swap with a USA ti and would delete all the components above and pass emissions.

There is another flash that can be used for cars with headers no cats and instead just rely on a base map to tune the mixture and does not use the 02 sensors to trim the mixture.

With that said anyone have an ECU with part number 1438877 laying around I could buy?
