need to filter out bit7(accel/decel) records from veanalyse

Postby Gruelius » Mon Mar 12, 2012 4:56 am

Gday,

Trying to finish car tune, to tune boost isnt ideal with the autotune feature, and to tune the boost sections id like to see if i could filter out the records where accel is going on, atm its throwing off ve's cause its seeing the rich or lean spikes.

would [TPSacc] = 0 do it?

basically i want the time that triggers a accel event + the time that the accel pulsewidth runs (so .3ms in my case.)


Thanks

Currently records under TPS accel should be filtered based on the TPS Accel flag in the the engine field.

Can you post a short log that demonstrates the behavior?

EDIT: If you are using 100% MAP accel, then you may need an additional filter. Pure MAP based accel may not be getting filtered.

its pure map accel. i have a stable tps signal but was advised map is better for tuning.

the problem is my accel records werent right, so when it saw the lean spike it would throw ve's at it. but i guess if my accel is right and it filters it, the result shouldnt be too bad. Id just like to lose the records around hard accel moments so i have some solid data for VE tuning.

This custom filter will filter any map accel or decel:

(([Engine] & 64) > 0) || (([Engine] & 128) > 0 )
