Need Help For R32 With Rb25 Box And Ecu

[Stylz_32]

hey guys,

wondering if anyone can help me, i have recently put in an rb25 box into my r32, and bought a drift iridium speedo. coz i seriously couldnt be bothered hacking up senders and the having to refill the box with oil after the sender came out. now the speedo works fine but hicas is completely gone.

i have the r33 speedo sender wired one wire to the drift iridium speedo and one wire to earth on the body

i have wired pin 53 on the ecu to the r33 electric sender but it doesnt seem to work right.

i have a PFC and under speed ill be doing 50 km/h but it'll show 200km/h on the controller

is there anything else i have to do with the wiring to get it correct and hicas working again?
