Ok, will use "falling" as there is no "rising" option, and while Help file tells to use "rising" with VR sensors...

rising is for crank cam sensors, not the speedsensor ;)


Ok, so the F1 help file would need to be updated... ;)
Moreover with older fws my speedometer readings where ok with rising and 100Hz/100kph, and now they are no more....

Yes, i put the diode, and yes, I'm pretty sure that playing some more time with PID can take to better results, but i can guarantee you that with a normal position table as has Motec (refdc for Vems) the results are amazing...  ;)
buy motec then ;)  anyway, it works perfect on vems too :) just person has to know what he's doing :)) anyway even if you have ref position table on motec you still need to tune pid ;)

My customer bought a Vems, so that's what I have to map... ;)
Yes, sure, even with a normal position table you still have to map PID, but as PID work is helped by normal position, resulting DC are perfect...

Anyway, are you talking about 1ZZ/2ZZ vvt?
Something must be different from my setup (3SGE Beams), because my sectrig changes in one degree step, so it's never exactly on the target...
just post log :) after that it is possible to talk about something

in my opinion your cam target and cam position follows it perfectly :)) just rpm signal looks little bit jumpy, but I'm not sure what's happening in this log :)
