Installed my new DL1/Dash1 today but I can not get the RPM I/P to work using DL1 5v Tacho I/P.
ROVER K series with MEMS 3. I have spliced into the tacho wire which with no load shows 3.xx Volts at idle, so I believe this is a 5V O/P. RPM reads Aprox. 275 and when the revs are increased the Dash1 seems aprox 1/3 of actual RPM.
I have read some detail on the VOB setup and the last comment appears to be from RT support that this is still work in progress.
Tried playing with the DL1s conversion formula but no luck.
Any ideas please?

RT Support,
Yes you are correct. The Dash1 appears to show 1/3 of actual revs.
I tried moving the I/P wire to the "Spark in" and there was no change i.e indicated RPM was about 1/3 of actual. Also tried grounding the "Spark GRND" and this gave spurious readings in the 1.000s
Then tried adjusting the formula from:
O/P= 0 x I/P^3 + 0 x I/P^2 + 1 x I/P + 0
to
O/P= 3 x I/P^3 + 0 x I/P^2 + 0 x I/P + 0
This resulted in a "No Data" display on the Dash1.

Richard
