Road tuning filters for MAF

[tonn0297]

Hello, im trying to get some filters going for road tuning my MAF, but i can't seem to get the result i expect... here's the current formula:
([50091.156] > 10) And ([50091.156.avg(500)] > 10) And ([50091.156.avg(-500)] > 10) And ([50091.156.slope(2000)] < 5) And ([50091.156.slope(-2000)] < 5) And ([50020.113] > 20) And ([6310] = 0 or [6310] = 2 or [6310] = 3 or [6310] = 4)

([50091.156] > 10) And ([50091.156.avg(500)] > 10) And ([50091.156.avg(-500)] > 10) And
//Filter out anything under 10% throttle, and a window of 0,5sec before and after it goes over 10% (transients)

([50091.156.slope(2000)] < 5) And ([50091.156.slope(-2000)] < 5) And
//Try and filter transients, if slope is under 5% in the last 2s and 2s after a transient don't log

([50020.113] > 20) And ([6310] = 0 or [6310] = 2 or [6310] = 3 or [6310] = 4)
//Speed over 20km/h and the fuel trim cell not in decel (we really need a <> or NOT in the conditions)

But i can't see a change in the logged data or the count on the cells in the histogram, can some explain why? Ive looked at a few posts here exsplaning but i exspected no data if filter did not work.

So a tip to others that struggle with the filters, put it in a Math parameter and graph it, it will help alot rather than shooting in the dark... just note you need to close and open the log to update on math change
found out my TPS parameter was wrong.

So now the math looks like this:
[50090.156.slope(3000)]<5 AND [50090.156.slope(-3000)]<5 AND [50091.156] > 10 And [50091.156.avg(5000)] > 10 And [50020.113] > 20

the LOG on bottom graph shows the output of the parameter

Hi tonn0297,

Have you checked if the logging rate is fast enough to capture those transitions accurately?
Sometimes missing data points can skew your results, especially when working with slopes and averages.
