Will the V-AFC hack work with a JRSC (450 cc with V-AFC)? Do I need a FMU or can I just use the JR BTC and the V-AFC? I want to pass emissions here in Tucson, Arizona and will use the V-AFC with stock injectors then tune it with the 450 DSM injectors after I pass emmisions.

Please help and all coments are appreciated!

 

You can use it.. but why not go with uberdata and get rid of the vafc and a BTC... it will do both for less money.

 

jrsc doesnt require a hack...because its got the map sensor before the boost pressure so the map always reads vacuum no matter if your boosting 5 or 20psi. the stock inj can handle 6psi all day long...if you go up to 10psi, i think 450 would still be to large...maybe somewhere like 310 would be good.
