SAFC question

[i_heart_boost]

does anyone know if an APEXi SAFC is effecient when using 750cc injectors, or if it matters?

Most people would use DSMlink when you get into 750cc+ injector size. It technically still can be run, but it is not suggested with those size injectors.

is there any ill effects of doing it?

Your settings will be so far to the - that your airflow will be extremely skewed. This can lead to really high timing and poor performance because your ECU will think you are getting much less air than you really are.

ouch. to what cc's is an safc capable?

Also, PM andymoraitis as he will set you up with the settings when ordering your chip.

I am running 850's with the chip, I threw on an safc just so if I need to fine tune things, I can.. Although, The safc is not needed now.

650cc is where most people see the last place an AFC can be used successfully. Or, like 1993eclipseGS said, get a chip that in effect sets you back to 450's, so any adjustments you make are on the stock airflow numbers. You could run, theoretically, whatever size you wanted, in this case.
