RSM - Are they acurate?

[Guilt-Toy]

Reason why i ask is because ive got one on my R33 and i recorded a 13.02 & 13.00 and everyone is telling me that my 33 cant do those kinda times and that it must be totally out.

Ive checked the speedo on the RSM and it seems fine. the speedo on the dash is wrong but the RSM is right.

Are they 100% acurate? or just total garbage and im really doing 14's or something ?

It even said 4.77 0-100 on a good launch.....

I have the older Apexi one, not the Blue screened one...

anyone have one of these and recorded it while at the strip to compare times ???

anyone have any ideas how to make sure they are accurate? (i dont have a drag strip available where i live)

does yours have g-force sensor or just use wheel speed? With wheel speed only, anytime your wheels are spinning its inaccurate - think of how quickly the wheels can cover 400 m if they spinning, and how much less distance you'll actually have covered.

I used to have an AP22 which uses g-forcs to calcualte accurate figure. G-tech is similar, and I understand there is an add-on available for RSM to do the same.

No i dont have a g-force sensor.... its the old type that reads from the wheels.

I try not to wheel spin but i find when I do i get worse times.

They're not that accurate unless you get the G sensor, and still yet is a little off. It's not as good as going to the track and getting time slips there. That's where you can brag about your times and back it up solid.
