Change of final drive

Hi, i need some help. Recently i had a final drive installed (5.46 final drive) on my fn2r. Previously flashed with hondata and cruise control feature and dash meter (avrg speed, distance to run, fuel calculator, etc) were working fine. However after installation of the final drive, we adjusted the final drive ratio gear on the hondata and did the necessary speed correction to indicate the correct dash reading. After re-flashing, the cruise control and dash meters were not working. How can i solve this?
Thnks

Hi, i believe my tuner is currently using the 2.3.2
Dont know the previous version when it flashed however when we tried loading back to the previous map, cruise control n dash gauges also were not working.
Any help is welcome.

Hi spunkster,
My apologies. Version is 2.3.1
I am running on the standard fa/fg map based skunk 2 CAI with cat.
Also running only on eg/ek air temp sensor
For the past 2 years we had not had any issue with the dash meters or the cruise control.
All the while we have been running on this till the latest flash where the dash meter n the cruise control stopped working. Is there any way to resolve without remapping another calibration in AFM based?

We have remapped the tuning to AFM calibrations using the Fn2r group N reflash calibration.
However the cruise control still doesnt work. The cruise control option is enabled.
The cruise control disengages when we engage it. The final gear ratio also has been changed accordingly to 5.46.
Is there anything we are missing out?

However the calibration is such:

1st 3.267
2nd 2.13
3rd 1.517 44 countershaft teeth
4th 1.147
5th 0.921
6th 0.738
Final 5.46
Notes

Can someone please help. Also speedometer reading is incorrect. Do we have to manually correct it? Thanks

Return youre ECU back to stock and flash again youre new Map.
Maybe it helps.
