Meter is Malfunction

Hi all, sorry for havent update for a long time.
It took me a hell of time to make the meter functioning.
The meter cannot function since the new generation engine using different method compare to the old engine.

New generation Engine:
Meter <> Computer Box <> Engine

Old generation Engine:
Meter <> Engine

So, i have tried everything but still cannot work. I already put together the old computer box. but still malfunction.

At last, i've decided not to use the meter . just put apexi rsm meter.

It is very dissopointed. but "what to do" .. at least i tried my best to do it.

Now it is the time to make FMIC. Will post picture later.
