Hondata

A customer reported me that the Speedometer sometimes freezes for some seconds and the cruisecontrol deactivates by itself. I just noticed that sleeping Speedo Needle on the dyno while tuning.

Is this a know issue? How to fix?

This only happens with the spezial modifed 05+ RSX KPro ECU + Hondata conversion harness.

Application Notes

An primary oxygen sensor from the 02-04 RSX or 02-05 Civic Si must be used. The 05-06 RSX O2 sensor will not work.
OBD2 must be disabled to eliminate errors generated by the ECU looking for emissions items that the 05-06 RSX does not have.
The speed sensor spins about 100 times faster on the 05/06 RSX gearbox as compared to the 02-04 RSX. Above 65-70 MPH cruise control may not function smoothly and may cancel from time to time. Also see Tech - K20 Transmissions

Weak. :(

But thank you for the fast reply.

Does it work better with a external speed conversion box like the one from Hybrid Performance?
