[m50tu pnp wrong ignition pulse]

i would love to show you the diffence of the signal in test mode and when crankink with same setting and wiring but i can't ad more pictures :/

i think you should modify this test mode to give us the good signal or at least tell us in the instruction to not try the test ingnition mode unless you have oem bmw coils 

yes i will not burn the ecu, that was my bad 100% but it is because i had not spark ( in test mode) and i tried some others wiring en software settings 

the good wiring for vag coil (u5014) is the wiring long/normal i've posted on the 1st post of this discution 

[m50tu pnp wrong ignition pulse]

ok, engine is runing so to make this ecu work with vag coil (u5014) you need to do a pull up resistor like in the instructions that link gives you with the ecu except that you need to do it with the 12v and not the 5v 

after that set the spark edge in rising 

dont try to test it with the test page it will not work 

but when cranking yes it works 

my wiring was good since the beginning !

the coils were good too 

but i was only trying in test mode ... 

and finaly after a lot of things tried i've burn a pin ...

so the porblem is in the software of the ecu because he doesn't give the right signal in test mode

[m50tu pnp wrong ignition pulse]

hello, i just received the fix ecu 

there were a burn damaged ignition GND pin 55 on the bottom board cause by excessive current.

 

but i still have no spark with vag coils 

i checked the wiring 1000 times 

i have checked the signal out of th ecu with the pull up resitor wired and the signal is the same as i put it in rising or falling spark edge ...

when the spark edge is in rising the ignition test is off the signal is flat at 0v 

when the spark edge is in rising the ignition test 2 on the signal is most of the time rising at 12v and a pulse at 0v 

 

when the spark edge is in falling the ignition test off the signal is flat at 12v

when the spark edge is in falling the ignition test 2 on the signal is most of the time rising at 12v and a pulse at 0v

 

is it normal ? 

i dont have spark in test mode 

i did not try to start 

ok i think i have found 

in test mode it does not work 

but when cranking the signal is different 

most of the time at 0v and a pulse at 12v 

so i will try to start without testing in test mode 

[m50tu pnp wrong ignition pulse]

OK thank you very much 

[m50tu pnp wrong ignition pulse]

Do ibhave to send the ecu to you for à repair ? If possible ? 

[m50tu pnp wrong ignition pulse]

Yes standard probe x1 

100% sûre 

Sorry i can't ad more pics :/

[m50tu pnp wrong ignition pulse]

ok so here it is

i have some isues to ad some other pics ... i did the exact same test as above " ign6 pullup resistor 470 ohm 5v saprk edge RISING andcan see any pulse 

"1 file would exceed the total allowed size of 229.79kB, and was skipped"

[m50tu pnp wrong ignition pulse]

And the spark edge ? Rising or falling ? 

[m50tu pnp wrong ignition pulse]

OK so i do the same test but with a pullup resistor 470ohm and 5v ? Or 12v ? 

[m50tu pnp wrong ignition pulse]

here is the 6 ignition out put without pullup resistor signals

[m50tu pnp wrong ignition pulse]

ho nooo 

i've just tested one today with the osciloscope (ign2)

[m50tu pnp wrong ignition pulse]

hello 

im trying to have some spark on my m50tub25 turbo 

1st i wanted to put some vag audir 8 coils (U5014)

i did the pull up resistor mod with 470ohm on the 5v with no luck 

i've found on the link forum that you needto do the same pull up resistor wiring but with the 12v for this coil so i did but no spark 

i've tried with some vq35de coil, pull up resistor with 5v and 470ohm and it works i had spark

 

so i get back with the vag coil 

i tried two types of wiring vag short coil and long coil as i didn't know what size i have 

now i m 100% sure they are long vag coils

i tried back with vq35de coil and it get hot a lot 

i stopped the ignition test 

 

now i don't have spark with any of them

oem coil

vag coil 

vq35de coil 

 

i bought an osciloscope to check the signals 

i attach 2 pics 

the one with a signal that we can see is without pull up resistor it is the direct signal between the wire of the ecu and the engine ground spark edge : falling 

straight 0v and +1v pulse and -1v down (don't) know if it is good or no)

x axis 5ms/div

y axis 1v/div

the one with the straight line at 5v is the signal between the same wire with a pull up resistor between 5v and this wire and saprk edge : rising 

iit keep straight no pulse up or down so no sark

x axis 5ms/div

y axis 1v/div

 

i've attached the ecu file too

can you tell me what's wrong please ?

[1jz gte non vvti trigger issue]

ok i 've found my problem was my trigger callibration that was 360° wrong 

[1jz gte non vvti trigger issue]

hello, i think i have a problem with both of trigger signals 

trigger one is on the crank sensor 

trigger 2 is on the cam sensor (the one on the cam pouley side)

and the trigger scope doesn't looks good i think 

the engine cranks make some explosion noise but no starts the tank is full of e85 as i already drove the car with e85 before

i attached the screenshot of the trigger scope 

and the full base map 

thanks for the help :)
