Hi All,
I've tried my best to use the search function, but I can't find one of the wave forms I need to create. Whilst not an electronics whizz, I do pretty complex in car installations so I suppose I'm a half numpty ha ha.
I'm need to transfer the output from a gearbox to an input that the donor vehicle can accept. I've found as much information as I think you'll need, but if anything else is needed please let me know
Original form:
At 20mph
Freq 25.85hz
Upper 4.65v
Lower 10.44mv
Average peak to peak 4.75v
@40mph
Freq 47.38hz
Upper 4.65
Lower 10.44mv
Average peak to peak 4.7v
To convert to
@20mph
Freq 913.7hz
Upper 7.14v
Lower .41v
Average peak to peak 7.812
@40mph
Freq 1.52khz
Upper 7v
Lower .4v
Average peak to peak 7.35
Upper & lower figures have been obtained from placing a cursor on the oscilloscope graph, peak to peak has been computed by the program.
Both of the signals are just that, so won't require any real amperage, they input signal in trying to create is just a straight input into an ecu. The primary & created waveforms don't have to exactly be mph to mph, somewhere near will do.
I look forward to your replies and any further info you need.
Many thanks
Paul
