I have a case with m880 8 injector set-up 4 cylinder engine hayabusa.
4 primaries inj + 4 sec inj suddenly the no.1 sec injector starts sprays from idle.new wire lines new injector same problem.If sec injectors disable from ecu manager problem goes away.

Any ideas???

Answered this in your other post.

In a nutshell. Lower the Secondary Battery comp a little. When the secondary injectors are "off" they still get their battery compensation pulse, this is normal opperation becasue the injecotr should not flow anything at this pulse width.

You may have the wrong battery comp table for those injectors. Probably get them checked to make sure all secondaries do exactly the same thing, number one may have a problem.

Also,
With the engine running and the secondary injector giving fuel, press "F" for the fuel view screen and see if there is an individual trim for that injector.
