Settings for my new injectors

[scheides]

It will be next to impossible to get those to work properly without dsmlink or aem. Stock injectors are 450, 880 is roughly double that, and the S-AFC can only do 50% changes, not 100%.

As far as idle is concerned, larger injectors usually need to have the afc set to zero or even a positive value for the very lowest rpm setting. Try setting it to +10 or even +20 and see if it will at least idle.
