speedo innacuracy

Post by nunoctr »

Hi hondata,

Went to a drive in the highway and I was doing 260 km/h on the speedo.

In the datalog the car was only at 240km/h.

Today went to make a dyno and they said the car have a brutal speedo inaccuracy of more than 20Km/h.

The car is the FN2 civic and this is MAP based calibration there is in f.manager for the FN2 (with changes on fuel, ign. and cams).

What is the problem?

Thanks

Nuno

The race calibration in a FN2 will give an incorrect gauge speed due to the final drive. The datalog speed should be accurate. We plan to add a setting to fix this.

If you have an issue then we need to know:
- chassis type (eg FN2)
- calibration type (AFM or race)
- final drive
- gauge speed vs datalog speed vs actual speed
- actual speed determination method
- gear speed was measured in
- tire / wheel size if different from stock

The last version of the software allows you to correct the speed.

Yes it's ok now.
I put less 7% on the dash and it's = to the VSS.
Thanks

you need the last beta version of the flashpro software. Then go to the "calibration" and put -7% in the dash speed.
