Hi guys I´m newbe here , I acquired recently a 240sx with rb25det swap , with the apexi power Fc , and I have a few questions. My FC commander doesn´t read any boost press, is this normal or my map sensor is bad , or even not connected????The engine is stock , only greddy intake and front mount intercooler , and I´m thinking in 400whp with an upgraded turbo like garrett GT-35 , but I see that the power FC is tuneable only by MAF vs rpm in the rb25det engine , is any possibility to make a tune via MAP vs rpm , or the only way to go is replace the maf for a bigger one???

Thanks.

You don't have a Map sensor and you can't use one with the RB25 PFC.

Hmmmmmmmm , so.... I will not have any boost cut without a MAP......What would be the MAF needed to make around 450-500whp ????

A Z32 MAF will get you there.
