Problems setting RPM calibration on SAFC2 for N/A KA24de

I have all my sensor types calibrated.
Sensor Type:Hot Wire, 5-5, 1in and 1out
Now when I check RPM calibration after 2800RPM it seems to jump in calibration.
My actual RPM gauge is ahead of SAFC calibration by 280RPM.
I've tried everything the manual recommends and still can't find the problem, so I am assuming that possibly the wrong sensor type was selected.

the sensor type is correct, is your arrow point up?

Yeah my arrow point is up as well.
I really can't determine if the problem is the SAFC or if my RPM cluster is faulty..

well the rpms of the safc i would believe would be more accurate. but my rpms seem to match well both on the cluster and safc.

is your 6-6 a setting for NA??

Yep I just followed the SAFC manual. Daughter boards on the KA and sr are the same for s13's so I just followed what the Apexi manual told me for s13 SR's. Same format pretty much.

Right..With an N60 you should be using a 2in-5out, with a 1in-1out.
I've followed everything in the book with mine and even had A/F ratio's checked. Everything is fine accept for the RPM calibration, it's just bothering the crap out of me that I can't figure it out, and it's probably something really simple. Could just be my RPM cluster, it is old. I'll also check the speed sensors on the tranny and see if there still good. I also noticed that my digital speedo was off on my 1/4mile times.
Anyway just for reference....
VG30e, SR20de, and KA24de use the same sensor signal of a 5-5.
I plan on using an SAFC onto my VG33e frontier truck once I have put enough bolt on's the little truck that could.
