i will be installing a jrsc on a type r and ppl have told me that the set upwill run really rich top end . So my question is can i use a vafc to lean the car out top end and use the fmu at the same time ?? i was told that the fmu will overide the vafc settings making it useless .Is this true ??

 

I use them together. No the FMU does not make the fmu worthless.

Wish I had gone stand alone now, but it works.

 

HUH?
