EXACTLY....I'm 99% sure its indirect. and thats kinda why I still think Emanage is still just an oversized AFC don't get me wrong its got some GREAT features(auto injector sizing calculator, datalog, and of course MUCH more map resolution than the AFC)and is definently on top of its class as far as entry level piggyback systems, but still as far as fuel subtraction for running bigger CCs goes, its basis is the same as the AFC...strictly airflow(MAF, etc.) manipulation and nothing more...from what I see no direct injection control EXCEOT for maybe the sub/aditional injection map(which are only used to ADD fuel)

 

so does the split second have direct signal input?

 

I'd like to know as well...can't really tell from the directions, but theres is no indication of any injector wire splicing/cutting. my extremely uneducated guess is "indirect" control(but allows to to uses the MAP sensor for tuning reference)

 

Neither can directly control injectors IMO.

SS has MANY custom versions, so I don't know for sure what's possible, however the TWO main types seem to be MAFxRPM or MAPxRPM, not both.
