1991 240sx ini failed

Post by blindside73 »

I'm using the USB/otg adapter which works great on my 1996 S14 240sx but won't connect to my S13 240sx. It almost seems as the ECU isn't communicating at all. My s14 goes through several states during initialization where the s13 does nothing and times out. I am using the paid version of nds1.

What am I missing? Thanks

After doing more research I'm guessing i have a usb/otg adapter that isn't generation the 9600 baud clock on pin 8. I found some posts that show how to fix the clock for bluetooth adapters but not for the usb adapter.

Anyone know how to fix the clock signal on the usb adapters which is needed by the older ECUs? Thanks
