RPM Input DL1

[skip7]

I have set the RPM feed from my ECU (Megajolt), by piggy backing the tacho feed (to a Stack ST200). The Tacho works correctly. I have the Tacho feed going to the rL input. The rG is to a ground on the chassis.

The Megajolt documentation states that the " TACH OUT signal provides a 12V pulse for every ignition event".

Data is being logged, however the data does not tally with usage. I have tried changing a number of settings in Analysis (min, max, sensor type) to try to understand the data. All of which do not make the data match expectations.

Questions:

1. What can I change to make the data understandable in Analysis?
2. Should I have connected the tacho input to the rH?

Skip.

Hello,

In the analysis software click data> vehicle options> RPM and set the pulses per revolutions. Does this make the RPM look correct? If not please email me a run file and i will investigate. kieran@race...
