6th is 1:1 but some dynos may not like being run up to 172 MPH and I think the stock limiter stops you 100 RPM short of redline in 6th.

6th Gear for the IS-F

Find a Dynojet...

Turn OFF Trac & VSC..

Good to have numbers that are graphed SAE Corrected & Smoothing set to 5.

SAE Corrected numbers take all Elements into consideration, when the graph is actually plotted.

Usually, the 3rd to 4th pull in dynos repeated 5-6 times during testing, will also be the one to choose..

You will be able to see the difference in dynos after 2 or 3 of them as the power increases to its peak.
After a 1-2 pulls of decreasing power. You know that its time to end that dyno session.

This will Best represent true RHWP numbers.
(rear wheel horse power)

Dyno's after an engine cool down period (even a few minutes) will cause a spike in rwhp gain. Also, known as inflated numbers.



Good Luck
