Early injectors / Late Motronic... trouble coming?

[eddie124]

Hi all,

Just been browsing through a number of discussions here on Tech Help, and hit upon a discussion of injectors.

My Tourer has an early 325 is engine, so IIRC it has low-impedance injectors. But I'm converting the engine loom to facelift spec to match the main loom, so will my injectors work with the later ECU? Or do I need new ones? If so, which ones do I need to seek out (models, engines they came on)?

Thanks for your input on this.

Cheers, Eddie

do not mix high and low Z dude !

all 325i should have 714 light blues with 3 bar reg

Ant, 714? I thought the M20B25 injector was a 715? Mine was. Both 714 and 715 are high impedance, but I thought the 714s were an injector from the M42/M30? I'm confused. Bosch numbers?

My bad ! 715 is last 3 digits of the OEM units.

been swapping between builds for a few days, mind is numb !
