why timestamp count normaly from 0,00s to 7,55s, then jump from 7,55sec to 3284,30s then count normaly again to 3303,47s and jump to 6580,22s ?!?

am i missing something?

in accel PW chanel i have 8ms, and total pulsewidth is only 4ms ?!?

please look in attached image and help me understand whats going on...

no need to disconect anything

in idle setup just choose valve type = unipolar steper

start from slow freq like 20hz and watch behavior

theeese steppers are pone to be glued with shmoo so dont hesitate to remove it from throttlebody and make sure its clean and mooving according to ECU demand

Hi! can you attach logfile of cold start (please check if you run lanbda sensor when no rpm, and wait for lambda to heat up before crank your engine) allso your .emu config file will help a lot to understood your problem. generaly theese tables take efect only when cranking and then 50 cycles after ...

Shame on me... i missed that one in secondary trigger setup....

I will belive in that if they will not be equaly spaced... but of course i can be wrong...

I don think that 3equal teeth on cam will work, on my car i will grind off 2 of them and use only one

Which ecu you have? Emu or black? Im not sure how base map will help you if your loom is custom, you have to setup everything according your wiring...

Throttle body is what part number? In announcements section of thisforum is nice dbw database...

aaah now i figured it out! it cannot work.. your dwell time is 4.2ms and you fire output1 every event, it mean 3times per revolution, 5000rpm is 83revs per second, one second is 1000ms, 1000ms divided by 83 revolutions is 12ms per revolution,12 divided by 3 events per rev is 4ms. so your dwell can b...

not sure if dual variable cam, and drive by wire throttle, is good engine to play with as beginer... how your wiring is done? you have new loom? or some plug and play conector?

allso fueling squirt tvice per cycle checkbox should be checked

EDIT: wrong idea !!! toyota multiplex igniter needs diferent setup (credit to Denny from ecumaster usa) following text will be right only if you connect coils directly to emu with no igniter ignition outputs seems to be messed up i think that you have 3 coils conected to outputs 1,2 and 4 (dont kno...

i think your issue is ignition related, too big spark plug gap - adjust gap to 0,6mm too small dwell - increase 0.5ms poor coil + - measure with osciloscope when engine running on coil + if voltage drops down too rich mixture which spark can´t go thru - decrease VE -afr is jumping from 12 to sky , b...

In EMU configuration there is allso checkbox, which define real throttle plate position as tps signal in ignition or injection calculation instead of pedal position which is wired to TPS input

But be careful! Im not sure about BLACK, what i wrote is for EMU

Karel its not realy clear, if it is same as for EMU, then:

Pedal has to be wired to TPS input

And throttle position sensor has to be wired to spare analog input and then configured in dbw menu

Thank you!!! Realy precious piece of puzzle

Ok so i look thru logs and on subaru ej20 i found -836° on nissan sr20 i have -723° on some ford i have -677° and -825° on mx5, so it seems that values are allways negative and higher then 360. Ej20 and mx5 is wery interesting, because its offset cannot be compensated with VVT setting "cam1offset" b...

And its even more interesting then that, because value in case on picture is actualy negative so -611.44° so it seems to me that range can be -720° to +720°

So cam 1 angle will allways be in range of 360 to 720° ?
