newest vemstune
http://www.vems.hu/download/v3gui/NIGHTLY/VemsTune-Install-2016-10-01.exe
http://www.vems.hu/wiki/index.php?page=GenBoard/UnderDevelopment/FirmwareChanges
put it into webcache/fw folder in vemstune install, install over firmware web tool

I have the latest VT...
is the 1.2.34 safe to street use?
I saw it has some vvt upgrades...
Thanks

Using latest VT 2016-10-01
Firmware info = 1.2.36

Extracted the new ini files into the Vemstune/Config folder, but still getting the "VT is older than the fw you're using" message!
How to manually update the downloaded ini files?!

Thanks

ignore it ;) just check config validation :)

Talking about the 1.2.36 fw settings, Motorsport/camshaft angle control,
what are intake refdc up & down supposed to be?

this is for you to decide, test, play, think with your head ;)

Yes Mate, I already tried... I saw that they both increase base duty cycle the solenoid starts from.... but I can't really find a difference between up and down!

PS: talking about 1.2.36, I found that Speed sensor setup is missing the Rising option.. is the same there?!

so what is the problem with solenoid? :)

The problem is that I still have sectrig oscillations at lower target angles that disappear when at higher target angles...
I think it could help a table refdc vs target....

PS: can you please confirm the 1.2.36 speed sensor issue?

Thanks...

there is no issue with speed sensor, it has to be like this :)
I think you need more experience doing simple tasks ;) play with pid values a little, it works absolutely beautiful + did you put diode on vvti solenoid output?

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

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

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....

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...
