Another note, this is what the scope output look like when the ECU is driven using the linear output with 0.97 for 5V and 1.03 for 0V
And this is what it look like when using 0.98 for 5V and 1.02 of 0V
Please note that I’m repeating the same sequence over and over, as it’s tedious to repeat simulate a scope using excel.
In all cases, I’m using the same time base, as you can see, the linear output is much more responsive than the narrowband, and the ECU is reacting a lot faster.
I’ve done some tests using 0.99 for 5V and 1.00 for 0V getting even better result, still no code…
Looks something like this
There is a whole lot less time spent halfway.
You can see the same phenomenon when logging in HP Tuners :
Narrowband Output
0.97-1.03
0.98-1.02
0.99-1.00
Again, using the same time base for all charts (Zoom 30s)
Thank you.
