Apexi PFC Inj Map

[AusFreak]

Hello,

 

I was hoping someone could explain to me the numerals the injection map shows on the Apexi Power FC's Commander.

Seems to be 3 digits with no decimal place from what i can tell, example 100 109 

How is this calculated?

You mean these numbers?

Bigger numbers means more fuel.

Yep this one, is that based on a percentage or how is that calculated?

Arbitrary number, more means more fuel.

Not related to volumetric efficiency like modern ECUs.

Hrmm okay - so with the commander no way to calculate the af/r ? im assuming 100 is 14.7

No because then bigger numbers would mean less fuel.

[AusFreak]

how did you come up with that? It makes more sense that a higher number would mean more fuel wouldnt it?

Which is why you are wrong

[AusFreak]

i didnt mean that the injector timing was af/r

Get a Haltech or Adaptronic or Motec or Emtron 

Plug up a wideband o2 into the ECU anf all your questions will have logical answers.

Sell or throw that PowerFC in the bin.
