RPM reading is off, speedo not working
R33 rb25 gts-t in a 1995 240sx.
Swap is done. Have a S-AFC II installed. My tach reads about 1500ish while the S-AFC II reads about 900ish. What can be done to correct this?
The speedo isn't even working. Wiring was spliced by Mckinney's. I remember vaguely hearing something about splicing in a plug from...a 240? Forget. Any help would be appreciated.

Did you use the RB lower engine harness... If so you gotta yank it and use the KA lower. That will fix your Speedo problem.
Check my Yahoo site for the guide to prepping the KA lower...in the files section.
