Hi Rohan
Sorry for very long delay with answer.
Will wait your test on itbs.
Look here what folks from CIS countries do with VFM when they couldnt buy new or remanufactured:

They use contactless TPS from Daewoo vehicles. Works not so good( the cuoldn't tune charcteristics) , but it's better than nothing
To make immortal VFM I am thinking about developing PCB with angle position sensor, which user can install in original vehicle's VFM.
Remove old resistive board from it, and install install new one converter with contactless sensor.
There will be converter,sensor and Bluetooth module inside original VFM.
Software and firmware will be almost the same.
So user can tune old VAF as you tuned MAF
In some cases it is better to use VFM instead of MAF on old engines.
Because they produce a lot of cranckcase gases which can degrade measuring element of MAF- it is actual for CIS
Have you recieved the repaired converter ?
