Nistune RPM issue

Post by CHIEFAPONTE »

I recently conducted several pulls on my car and noticed the log never recorded anything above 6400 RPMs while the RPM gage on the vehicle has shown RPM above 7000

My car is a 1991 R32 GTR.

I have searched the forums but have not found any info.

Any info you can provide will be greatly appreciated.

Please post log file (stream mode) during RPM pull. I've not noticed this on the bench

See log that I just made and replayed

Matt,

sorry for the delayed reply. attached is the RPM pull. one thing I noticed is that as I increase RPM the mismatch gets bigger. At the 3000 RPM range, the gage on the car indicated 500 higher, at 4K split is 700; by the time I reach 8000 on the car gage, the nistune is only registering 7K
