I use EcuEdit in all tuning, as you can see from my post. The Dyno will complete the usage, making me dump DD.
This would be oe software I would pay for, if I still continue to tune with my new hectic job.
First of all, i would like to apologize for my English, as it is not my native language.
Yes, i saw it too, very wavy, even after smoothing it.
I've been examining my data, and I found out that the speed-sensor is not accurate enough, sometimes it goes up 4 km/h in 250 miliseconds, and then it stays for 750 miliseconds the same.
And the measuring is not accurate enough, let's say 85 km/h could be 84,5 to 85,5 wich makes a lot of difference for the calculation.
In sample 1 jou have a value of 84,6 wich is 85 in the log, then at sample 2 you have a speed of 85,4 in 250 miliseconds time, and the log still shows 85.
So according to the log, in 250 miliseconds there has been een accelecation of 85-85=0, but in reality it was 85,4-84,6 = 0,8 that's a lot of accelecation in 250 miliseconds.
Then you get inaccurate readings.
Maybe it's an option to change your input value to RPM in stead of km/h as the RPM is just a factor of the speed.
So, you take a sample of data at some time, (speed/RPM = factor).
And then you can calculate the speed from the RPM (RPM*Factor = speed).
At least you have a speed-reading at every datasample, and would make the waving a lot less...
