Blitz Power Meter Problems

[nigelswazi]

Hi

I have just finished connecting my Blitz SBC and Power Meter, all works great except the power meter is incorrectly reading speed, its exactly half the real speedometer speed? Anyone know how to fix this?

Anyone else have this problem with theirs? Its installed in an R33 GTS-T.

Thanks all help would be appreciated

Do the calibration again (accelerate to 40 then press enter). Mine always seems to be a few km/h below what the speedo says.

Yeah the speedo in most cars overestimate a tad (intentionally?) compared to the speed sensor.

Yeah but its exactly half the in car speedo. Could it be something to do with being de speedlimited? Is there something that halves the speed signal before the ecu just guessing but does such a thing exist??

Thanks for your help I will attempt calibration but figured if it was that out it could be something else.

Thanks

If you have a speed delimiter, then this will be the problem. You will have to wire the Blitz Power Meter to the speed signal before it get's converted by the delimiter.
