Hello.

Somebody knows why Apexi SAFC not works in K20A2?

thank you for help.

 

iVTEC is different than the old version and the original VAFC won't control it... so Apexi released the VAFC II to work with it.
It has to do with the VTC part of it, I'm not fully sure on the reason.

 

I know that vtec and ivtec are different system,

but I don`t want control ivtec,

I only want adjustable fuel curve,

that`s mean k20a2 has other map sensor than previous b series engine?

 

If it's an safc, or an safcII either of them should work for the fuel curve as long as that's all you're trying to adjust. There haven't been anyone saying it hasn't worked before to my knowledge.

Are you having problems with it? You might get more information on CRSX.
