Ignition EMU

[Urosch89]

Everything is ok now! The VE was too small (90%) and the car was lean.
Now i put 125% anche lambda is 12.5

Send the log in log format. Looks like there is too lean.

Jakub,

with wasted spark, it fires

ign event 1: coil 1 + coil 4
ign event 2: coil 2 + coil 3
ign event 3: coil 1 + coil 4
ign event 4: coil 2 + coil 3

so in order of coils 1-3-4-2 are fired -where- 4-2-1-3 are WASTED.

so I connect like this :

coil 1 to ign1
coil 4 to ign2
coil 3 to ign3
coil 2 to ign4

it's a bit different than your
Coil 1 to Ign 1
Coil 4 to Ign 2
Coil 2 to Ign 3
Coil 3 to Ign 4

is there any difference practically ?

Hi!

What I suggest is to connect these coils to EMU without external module.

You have two option:

1) Preffered one - connect each coil to separate ignition. EMU has ability to fire two spark at once if they are connected in the following way: output 1 & 2, output 3 & 4 and output 5 & 6.
So if the engine has firing order 1-3-4-2 you need connect coils in the following way:

Coil 1 to Ign 1
Coil 4 to Ign 2
Coil 2 to Ign 3
Coil 3 to Ign 4

The output configuration should look as follow:


2) You can connect two coils together to one ignition output. However for full sequential mode you will need to rewire it.

Coils without amplifiers are quite bullet proof, however due to the fact that they will fire two times per cycle it is wise to keep dwell time as low as possible.

If you have possibility to start in full seqential it is advised to do it.
