Hi all,

I have a 1998 4Runner 3RZ with a TRD supercharger. I'm currently running a 2.5" pulley (~5psi) and stock injectors, but I have a 2.4" pulley (7-8psi) and 370 cc/min injectors waiting on the workbench.

Last weekend, I finally got around to installing a URD FTC1-E I bought a few years ago. I'm getting the hang of tuning it using the R4 software and a BR3 scan tool, but I'm wishing there was a way I could measure injector duty cycle. As far as I can tell, this parameter isn't exposed via the BR3 and the OBDII interface, is it? Assuming it isn't, is there a way to measure IDC on these motors without buying yet another interface device? I'd like to know what IDC I'm at now @ 5psi/stock injectors before I change boost and injector sizes.

Thanks in advance,

Jeff
